A dim or faint picture on your computer's LCD could indicate various problems, ranging from a bad video card to a simple loose video cable. In some cases, your LCD's inverter board or backlight bulb fails and requires replacement. If adjusting your screen's brightness doesn't help, and all cords and connections are tight and secure, start troubleshooting where the problem may originate to find the proper solution.
Flat screen computer monitors or televisions use a liquid crystal display, or LCD, to display images. These images are comprised of thousands of pixels, which rotate through three subpixel colors; red, green and blue. Manufacturer defects and damage can cause these pixels to malfunction or become stuck, showing only a black spot. Dead or stuck pixels sometimes have a tendency to spread to the pixels nearby, creating a line or large spot of black space.
Computer monitor dual screening works by connecting two monitors to a single computer that has the capability to display on more than one screen at the same time. In order for dual-screening to work, the computer's graphics card needs to have multiple display output ports and support dual monitor display. Dual-screen configurations can also be setup by installing two of the same graphics card in the same computer.
Those pesky colored vertical lines that show up on either side of a computer display are usually caused by a bad connection. The connection often can be fixed with moderate adjustments to the cable and ports. However, the problem may require replacing the cable or it could be an indication of pending hardware failure. Lines appearing on the right side and the left side of a computer display are caused by the same problems.
Getting a higher resolution screen can, but might not, improve a video's image quality. Screen resolution is one factor that affects how the viewer perceives video quality. The screen resolution can improve or worsen video quality depending on how the video content and how the content is being viewed. Video quality is affected by how the resolution relates to the source video's quality, how far away the viewer is from the screen and how large the screen is.
Unlike their large CRT ancestors of yesteryear, LCD monitors don't use what is essentially a big light bulb to illuminate the screen. Instead, they use a thin backlight bulb, powered by an inverter card. This card, often referred to as a board, converts the power received from the computer into the proper voltage needed by the backlight.
LCD monitors have evolved significantly in the years since they began replacing tube monitors. In addition to faster refresh rates, the flat screens have become flatter while offering a greater number of pixels. The price of these technologies has also evolved, relating to both the technology and the overall market for the products.
Most modern computer monitors have landscape-oriented displays. This is useful for tasks that require a large amount of horizontal display, such as watching films. On the other hand, vertical, or portrait, orientation can open up screen space for other tasks, such as reading documents without scrolling. Many monitors support rotation; some even have frames that make this process easier. Ultimately, you will need to configure your display settings if you flip your monitor on its side.
LCD displays in laptops and monitors are illuminated by a fluorescent backlight. If the backlight fails it can exhibit some odd symptoms along the way. Pink displays, fading or dimming, and faint, unilluminated screen images can all indicate that it's time to replace the display backlight. Before making the repair, of course, rule out other factors such as software and loose connectors that could result in a display that doesn't work or doesn't look right.
Connecting your computer to two monitors is an effective way to give yourself more screen real estate that you can use to work on several applications at once. However, two monitors can take up a lot of space on a desktop, and they may perform inconsistently. Instead, connecting your computer to one large monitor still gives you greater screen space with which to work, and the Snap feature in Windows gives you the flexibility to work with several apps simultaneously on the same screen.
Connecting an HDMI-compatible GPU to an HDMI-compatible monitor just involves connecting two ends of the same cable to the same port type on both devices. Both sides of the cable are male and both ports are female, so it can connect regardless of cable direction. However, connecting one HDMI-compatible device to a non-HDMI-compatible device gets a little more complicated and requires using an adapter on the computer's side to adjust the signal and connection type.
The NEC MultiSync EA221WM desktop monitor's swivel stand allows you to easily rotate the monitor so you can use it in portrait mode instead of the standard landscape mode. By turning the monitor sideways, your picture becomes 18.7 inches high and 11.7 inches wide, making it easier to view long Web pages or lengthy word processing documents. Unlike many tablets, however, the monitor doesn't automatically change the picture orientation when you turn the screen, so you must change the orientation yourself in Windows.
Installing a second monitor on your computer with a split VGA signal allows you to view the same picture simultaneously on two different displays. You can split the VGA signal using a simple VGA splitter device you can get online or at a local computer electronics stores. If you're trying to view different pictures on the monitors, however, using a split VGA signal won't work; instead you must use a video card that has two separate VGA output ports, or attach the second monitor to a DVI or HDMI port if one's available on your computer.
Some ASUS monitors include what ASUS calls "Splendid Video Enhancement Technology." This technology contains pre-configured settings to change the monitor's performance to better display specific types of content. The five modes include Standard Mode, Scenery Mode, Theater Mode, Night View Mode and a Game Mode that helps you see on-screen details in your games.
EMachines computers are typically inexpensive notebooks and desktops. While they may represent the lower end of the home computer market, they still have industry-standard ports and connections. With an eMachines desktop, the only way to use the computer is with an external monitor, while a monitor can give a eMachines notebook both a physically larger and a higher resolution screen so that you can see more of what you're doing and see it more easily. On a desktop, the monitor is plug-and-play, while a notebook may require you to press a special key combination.
External monitors can offer a whole new scope for your display, including a larger screen, better colors, better sound and possibly more features than your internal monitor. There are several different types of connection options between a monitor and a computer; the one you use depends on which ports your computer and monitor have in common.
If you need to use two monitors showing different images, you'll probably need to add a video card to your computer. However, sending the same video output to two monitors or to a monitor and a projector is a much simpler process. Since SVGA video signals are analog and carry no special encoding or copy protection, all that you need is a splitter or switch box that connects between your monitor cables and your computer's VGA output. Given that SVGA signals have relatively low resolution, you can frequently use an inexpensive splitter rather than an amplifying switch box.
Video Graphics Array and Digital Visual Interface are two comparable display connection standards. However, a cathode-ray tube is not connection standard, it is a type of screen that has been replaced by flat-panel technology. DVI was created to replace VGA, but the process has taken more than a decade and VGA support is often carried for legacy compatibility. LCD, LED and plasma flat-panel screens have removed CRT from the market.
If your work requires you to spend long hours staring at a computer screen, you might be experiencing increased blurry vision when you try to focus in the distance. According to WebMD, between 50 and 90 percent of all people who work at a PC screen experience problems with their eyes. These problems are also more likely to occur if you are nearsighted. Nearsightedness is known to be hereditary, but there is also growing evidence that a lot of computer work may influence the condition.
To get an accurate color calibration on a professional video monitor -- or any monitor, for that matter -- you need to run an SMPTE test pattern. SMPTE stands for the Society of Motion Picture and Television Engineers, which developed the standard to take into account recording and transmission signal variances. Calibration test patterns are included in all major editing software packages like Avid and Final Cut Pro; you can also download them online. Make sure you use a test pattern made for your editing setup.
Apple’s HD LED Cinema Displays use a proprietary port known as the Mini DisplayPort. While most new Apple computers are equipped with the parts necessary for connecting to one of these displays, PCs with traditional hardware ports will not be able to do so without some sort of an adapter. Once you have the necessary adapter, however, connecting your PC to an LED Cinema Display follows the nearly the same steps as hooking up any other monitor.
As of March 2013, Samsung sells roughly 30 monitors -- ranging from 19 to 27 inches in size -- for computer and television applications. The 27-inch S27B970D represents the high end of Samsung's monitor line. By comparison, although it is still a high-performance device, the 27-inch LT27B750NDX/ZA monitor is an entry-level device at about half the price of the S27B970D. Comparing the two devices illustrates how resolution quality, features and warranties differ as you move up through Samsung's monitor product line by price.

A 4-channel digital scope, also known as an oscilloscope, is an electronic instrument that displays signal voltages on a monitor screen. The scope is used to see the precise shape of a voltage's wave, as the shape is displayed on the screen. A commercial oscilloscope can cost anywhere from $200 to $2,000, depending on its quality. You can make your own oscilloscope using an old CRT monitor.
Even if your computer is portable, you may use it at one or two regular locations, such as at a certain desk at your home or office. Using a laptop docking station allows you to quickly plug your computer into a variety of peripherals such as an external monitor where you use it most often. If problems arise connecting or disconnecting your laptop from its docking station, apply standard troubleshooting techniques.
Introduced in 2002 and selling for nearly $1,000 at the time, the ViewSonic A90F cathode ray tube-based computer monitor was considered state-of-the-art by many users. A decade later there are still some A90Fs in service, many in public schools and other public institutions. Screen problems with the A90F can come from several sources. Some of these have easy solutions; others are not so easy to fix.
Dell released its E551 monitor in the early 2000s. No longer in production, the E551 is a 15” CRT (cathode-ray tube) monitor which is significantly larger than its contemporary flat-screen counterparts. Because the monitor is nearly a decade old, Dell no longer supports or provides drivers for the E551; however, the monitor’s user guide is still available on Dell’s website. If you are experiencing difficulty with your E551 monitor, the monitor’s service code will provide Dell with any information they may need regarding the item.
ViewSonic's A90f+ is a 19-inch CRT computer monitor with a maximum resolution of 1792 by 1344. The display produces saturated colors and high-contrast image output using ViewSonic's proprietary UltraBrite 3X and SuperClear technologies, the latter of which incorporates enhanced phosphor treatment and a glass filter. Although the A90f+ uses various optimized refresh rates to prevent flickering, scan-related problems and other issues may arise.
Despite what you may see in movies or T.V. shows, viruses and malware rarely make their presence known by altering a computer's display. Even more rarely is their malicious payload code to make your computer screen blur along the lines to simulate the pincushion effect. While it is possible that a virus is causing the problem, it is much more likely due to bad circuitry in your monitor.
Flat-panel LCD monitors use a very different technology than the older, boxier cathode ray tube (CRT) monitors. LCD monitors use liquid crystals to form colors in each pixel of your screen. This liquid crystal technology creates a sharper image than the CRT monitors, but it also comes with its share of problems. If you see squares, vertical lines and rectangles, or other geometric shapes on your LCD screen, the problem could be as simple as a loose cable or serious enough to require a new monitor.
As technology develops quickly and new gadgets constantly incorporate the latest features, many users have begun to combine their electronics into integrated systems. One common example of this trend is the substitution of a computer monitor for a TV, made possible through a simple cable connection, to enjoy the combined features of television and a computer in a single system. This setup can reduce equipment costs and use, but is not necessarily an energy-saver without additional steps.
The Magnavox CM2089 monitor was made in the early 1990s. This CRT monitor has a maximum resolution of 1024 by 768 pixels. On most computers, the monitor should plug in and automatically display your Windows desktop. In some cases, drivers may be needed to get the monitor working properly. If you still use older versions of Windows such as Windows 95 or 98, the driver installation will get the monitor working properly.
Though other storage media options are available, the majority of the data stored on computers is stored on hard disk drives. Creating smaller formatted partitions on large-capacity hard drives aids in data organization. Partitioning also allows installation of different programs or operating systems on the same drive. The data stored in these partitions clusters in different ways depending on the operating system and partition format type.
The LGW86 series of monitors offers a tremendous amount of features and configurable options. As with all display devices, LGW86 monitors operate within a specific resolution, color and frequency range set by the manufacturer. When troubleshooting your monitor, identify the category of problem you are having and proceed accordingly. If you are having an unidentifiable problem, you can efficiently repair most causes by restoring the factory default settings.
Stuck pins sometimes cause of computer monitor and cable problems. They can make a computer monitor cable no longer work, resulting in a blank or distorted monitor image. They can also make disconnection or connection of a cable impossible. The type of method you use to remove stuck pins depends on your situation.
When the contrast settings box pops up on your monitor, it can indicate a problem with the computer settings or the monitor itself. In many cases, the issue isn't related to contrast at all but is simply a general settings problem. By taking steps to eliminate potential problems, you can narrow down the potential causes and reduce the need to spend hours on the phone with technical support.
Various problems with an analog screen can cause screen flicker. A Digital Visual Interface converter changes an analog video signal into a digital signal. If you convert the signal from your computer to DVI, you will need a monitor that accepts a digital signal, but whether that reduces flicker depends on the nature of the problem.
VGA is one of the standards that monitors use to connect to your computer. The VGA connection is a trapezoid connection with pins in it to connect and secure it. Properly securing and grounding your VGA connection ensures that your monitor receives all of the information your computer transmits to it; if you don't ground and secure the connection, your monitor may disconnect or return an error message because the signal is not getting through. The VGA cable carries the video signal from the computer to the monitor.
The screen is the primary point of focus on a computer. Replacing the arrays of blinking status lights on early computers, monitors now provide a rich multimedia viewing experience, but the name has endured. A Council for Research Excellence study found that American adults spend an average of 8 1/2 hours looking at screens, while in a scientifically conducted telephone poll by Poll Position, 64 percent of respondents said that they spent four to more than 10 hours a day looking at a screen. According to a 2001 Educational Testing Service research report on the effects of screen size and…
Choosing between a standard-sized computer monitor or a widescreen can be a dilemma. Many people enjoy the extra horizontal space for watching wide-aspect movies, playing games or arranging multiple windows on the screen. Others prefer the standard 4:3 ratio to the widescreen 16:9 ratio because for them the widescreen just feels shorter than a standard monitor. When shopping for a new monitor, consider what you will be using it for most and compare the advantages and disadvantages of each before making a decision.
The ATI Radeon HD 4850 X2 contains two graphics processing units on a single card, allowing it to drive multiple displays or run graphically intensive programs and games. The card features four high-definition dual-link DVI outputs and a single standard-definition S-video output. These outputs, with the correct adapters and settings, provide a variety of ways to connect the card to a high definition television.
Before the days of LCD monitors, tube-based sets, or CRTs, developed a phenomenon called burn-in. Even turned off, these sets permanently showed the shapes of screen elements that appeared continually during computer use, such as menus and window elements. CRTs may have fallen by the wayside, but LCDs display their own persistence behaviors. Dead pixels never activate at all. Some pixels stick displaying one color, instead of changing colors constantly as your onscreen content changes. Other than replacing your monitor, your only course of action is to determine the location of stuck pixels and attempt to unstick them.
The length and quality of the video cable you use can determine the clarity of the signal received when you connect a monitor or television to your computer system. Factors involving the cord and surrounding objects can cause interference or degradation of the video signal, making the image appear blurry. When you add the element of distance, the possibility of a blurry image increases.
To use less electricity and save power, your Dell monitor features an option to automatically switch to "power save" mode when the device isn't actively in use. Normally the monitor will return to normal operation by simply tapping a key or clicking your mouse. Your monitor may refuse to leave power-save mode and display an image if you are experiencing a problem with your video card's driver or if the monitor's cables aren't properly connected.
The I-Inc CY199D LCD computer monitor, ideal for both work and entertainment, boasts an eight-millisecond response time, integrated speakers and bright, accurate color. You may occasionally experience a poor-quality picture, no picture or an error message on your CY199D monitor. Changing the monitor's settings usually fixes these problems.
When buying a new hardware component for your computer, such as a liquid crystal display monitor, there are many factors to consider, such as response time. Knowing what the response time values mean can help you choose the monitor that is best for you.
Monitor display problems manifest in various ways, including strange vertical, horizontal and diagonal lines. The appearance of unusual lines along the length of your monitor generally indicates a problem with one of three components: the video cable, the video card or the monitor itself. Troubleshooting is fairly straightforward and can help narrow down the true culprit quickly.
Monitor problems on your computer or laptop are fairly easy to detect, but often require some trial-and-error to diagnose. A screen with a loss off color displayed could be suffering from a number of problems involving the cable, graphics card or monitor itself. A second monitor can help narrow down the cause of the problem, and point you in the right direction for the solution.
If your computer screen is reading top-to-bottom instead of left-to-right, you may have inadvertently switched to portrait mode. Some computer screens are capable of displaying in two different modes, which gives users maximum flexibility. By learning about these two modes, and about how to access your video card's settings, you can learn how to return your screen to normal.
Unusual black lines on your computer monitor indicate a problem in one of three components; the monitor itself, the graphics card or the motherboard. A second monitor can help you narrow down the true source. If the vertical line also appears on the second monitor, the problem lies within the circuitry of your computer. A clean image on the second monitor indicates the display problems seen on your original monitor are due to a fault within that monitor itself.
The Acer X213W is a flat-screen LCD computer monitor, measuring 21.5 inches diagonally. Technical glitches within the monitor itself -- including defective connections, failing bonds and damaged pixels -- can create vertical lines on the screen that can appear in various locations. Additionally, improper connections -- anything that interrupts the flow of power or the computer's signal to the monitor -- can also cause vertical lines, as can monitor-incompatible settings on your computer.
Provided the plug type matches, any monitor can display the image output of any video card. For the best result, however, you need to consider the native resolution of your monitor and the resolutions available on your video card. Running your monitor at a non-native resolution will decrease image quality. Even if your card supports the native resolution of your monitor, it might not be able to run high definition videos and games at that resolution without lag.
Hook up a TV to a computer or laptop using an HDMI, Mini Display Port-to-HDMI Adapter, DVI, VGA or S-Video. On your big screen TV, you might have a home page that is very small, preventing you from seeing anything, or the resolution might be far too large, with enormous icons and text taking up the entire screen. The settings on the Web browser and the resolution settings on the computer determine how home pages fit on the television screen, as well as the overall resolution settings for your computer. You simply need to adjust these settings.
The HP Pavilion mx70 is the 17-inch version of the mx computer monitor series from computer manufacturer Hewlett-Packard. One of the most common problems with the mx70 is a blank or dark screen after turning on the desktop to which it is connected. If you experience this, follow the steps outlined in the troubleshooting section of the mx70 general information page at the HP website.
Whether you're using an LCD, Plasma or CRT PC monitor, the screen must be configured to the correct resolution and picture settings or the screen will be blurry. Most monitor resolutions range anywhere fro 800x600 pixels to over 2560x1600 pixels depending on the size. LCD, Plasma and other flat-panel monitors support higher resolutions than CRT monitors. Larger monitors also display images and text in higher resolutions. With the correct resolution, maximize your monitor's picture quality.
Computer monitors use hundreds of thousands of tiny pixels -- short for picture elements -- to generate the images you see on your screen. A number of pixels a monitor has is determined by the screen's resolution; for example, a monitor with a resolution of 800 by 600 has a total of 480,000 pixels. Pixels are vulnerable to a wide range of problems, including dead and stuck pixels, defective subpixels and pixelation.
Liquid crystal display (LCD) monitors offer a crisper image and take up less space than older CRT-style screens, but they have their own problems, such as dead pixels or screen flickers. If the image on your new screen randomly flickers or fades in and out, you likely have a problem with the display settings on your computer. Changing the settings in your operating system and troubleshooting potential hardware issues gets rid of the flicker and gets your screen working again.
The IBM ET1720l is an LCD monitor with touchscreen capability, allowing users to interact with their computer without using a mouse or keyboard. If your ET1720l monitor will not come on, you can try a few simple things to diagnose and fix the problem. These troubleshooting tasks often fix simple problems, but you must have more serious issues taken care of by IBM or a certified repair shop to keep any warranty on the monitor.
You can configure your TV to be the monitor for the computer to which all of your CCTV cameras are connected. Enabling this connection requires you to determine the input type that's compatible with both your computer and TV, then use the correct cable to connect the compatible inputs. Once you connect the computer to your TV, you can position the camera windows to display multiple feeds simultaneously.
The ViewSonic VG920 LCD monitor offers a small LED along the right side of the front of the unit to indicate the presence of power. An orange light indicates the monitor is off, while a green light appears when the unit is on. Power issues commonly occur from a loose power cable or dead wall outlet, so verify that the power source is active and connected properly before moving on to more intensive troubleshooting.
Confidential surveys of Fortune 500 companies by the Computer Security Institute describe hardware and software losses running into the billions of dollars annually. Surprisingly, up to 80 percent of these corporate losses are due to insiders. Monitor tracking by companies has proven to be a major deterrent to intellectual property theft. HP among others added a monitor tracking feature to their enterprise BIOS firmware to deal with this growing problem.
It's a long-held myth that magnets can damage your LCD screen or monitor, probably because that myth is rooted in truth. While magnets could harm the technology once used to create monitors, today's LCD screens are nearly impervious to damage as the result of magnets. By better understanding the relationship between the truth and the myth of magnet damage, you'll know when to exercise caution when using magnets around your LCD screen.
Most computers have USB ports to make connections to peripheral devices. Computer monitors use different types of video input formats. Visual Graphics Array provides a high-quality analog signal to a monitor, while USB provides a digital signal. Many computers have VGA outputs to connect to VGA monitors. Without one, use a USB-to-VGA converter, but be aware of the potential drawbacks.
All Dell desktop computers and most modern Dell notebook computers come with at least one socket to connect an external monitor to. The most common sockets include video graphics array, digital video interface and high-definition multimedia interface. The former outputs analog signals, the latter two, digital signals. Some external monitors requiring little to no configuration once connected, but certain settings or hardware can cause problems with the video resolution.
With the modern emphasis on recycling, the composition of computer peripherals, including monitors, are under scrutiny. Fortunately, modern monitors are made from more easily recycled materials, and consumer monitors no longer use cathode ray tubes. However, some materials in computer monitors may be toxic, and your old display should be recycled rather than thrown away.
The Dell Studio laptops with i5 processors are designed for high-definition media and to have more than one monitor display connected. This feature is easy to set up in Windows, and makes it easier to multitask between two or more programs. To set up multiple monitors, you will need monitors with connections compatible with your Dell.
Your Philips 190B monitor allows you to connect headphones via the earphone jack, send sound from the built-in speakers and connect another audio device. Common problems include not hearing sound from one of more of those features. In addition, if you manage several monitors on a connected network, it's doubly difficult to physically adjust the sound on each individual monitor without losing productivity. Some insights on how the 190B works will give you the edge over sound control.
Unlike cathode-ray tube and plasma screens, the liquid-crystal display system in computer monitors and televisions does not produce light by itself. A bright back light shines through the LCD, where the light takes on the display’s colors and graphical shapes. As of roughly 2005, the lighting technology has been shifting from cold-cathode fluorescent lighting to white light-emitting diodes. WLEDs consume less power and are more environmentally friendly than CCFLs.
The advantages of a ViewSonic monitor are negated if you can't see your connected computer's display. The problem can stem from video cable issues, the monitor's settings or the computer's settings. Use troubleshooting to drill down to the specific problem so you can determine how best to resolve the issue.
The small size of netbooks makes them great for travel, but that size comes at the cost of power and screen size. As an result of these downsides, the monitor resolution on netbooks is lower than on most computers, often topping out at 1024 by 600 pixels. Before 2009, Intel restricted netbooks containing Atom processors from using higher resolution displays, though the company has since loosened the constraint.
At 1024 by 768 pixel resolutions, the Acer AL1516 produces sharp and clear images. However, problems with blurry images and text can result from improper display settings, issues with video graphics cards and cable connection problems. The 15-inch flat panel liquid crystal display monitor is compatible with computers that support VGA connections.
Computers have been using video graphics array sockets since 1987, and despite the age of the technology, most low- to mid-grade laptops still use VGA. Some pricier models, however, come with better graphics output and advanced video technology. If you purchased a high-end laptop, you might be surprised to find the VGA socket missing when you try to connect the TV to your PC.
Outputting your computer's display and audio to a 22-inch HP W2207H LCD monitor using an HDMI cable can result in various audio and video problems. Problems can result from hardware and software compatibility, external devices and even the settings on both the monitor.

When shopping around for a new computer monitor, your two primary choices are between an LCD, or liquid crystal display, monitor that utilizes light-emitting diodes, or LEDs, for backlighting, or a plasma display that utilizes electrically charged gas to produce the image. While both displays offer a high-definition picture, there are a number of performance differences between the two.
Dell computers are equipped with settings that enable users to conserve the energy consumed during normal computer use. Newer Dell models have built-in energy-saver settings, in concordance with the Energy Star requirements. Usually, changing the display options is a quick fix and requires no advanced knowledge.
The blue plug at the back of your monitor is called a VGA (video graphics array) connector. It is the male end of a VGA cable. The female end connects to the VGA port of your computer. The plug and the port are often, though not always, color-coded so that it's easier to connect your monitor to the right port.
While most computer monitor problems are beyond the scope of a multimeter to test, you can use one to rule out some of the more basic issues. A multimeter typically provides measurements for voltage, amperage and resistance, and if you have a slightly more advanced meter, you can also measure the frequency of the electronic signal. Measuring the direct current voltage output of your monitor's power supply can give you a hint about where your problem might be. If you have a multimeter that can detect frequency, you can also get a sense of whether an LCD monitor's backlight inverter…
The Samsung 940BW features a 500-to-1 contrast ratio and a four millisecond response time to improve graphics speed. If the monitor is not working properly, you may need to open the outer cover. You can remove, repair and troubleshoot components once the cover is removed.
On occasion, vertical lines and other display problems may appear on your Gateway computer's monitor. This type of problem typically calls for a reset. The connections should be reviewed and object interference ruled out to confirm that a reset is truly necessary.
Dell monitor picture quality diminishes if the flat-panel display isn't properly set up and configured. A fuzzy font can be unpleasant and difficult to read, especially if the monitor's maximum resolution isn't utilized. Whether you're using an external monitor or laptop LCD, several tips and troubleshooting information can optimize your Dell monitor to eliminate fuzzy text.
Monitors come in variety of resolutions, such as 1920 by 1080 for high-definition displays; however, images and text appear blurry if a monitor isn't properly connected or configured to maximize its full resolution. Whether you're using an LCD, LED or another flat-panel display, issues with blurry, fuzzy and unclear images can usually be solved with a some troubleshooting information.
Many users improve the look and feel of a computer by placing a background image or picture on the desktop. You commonly see this background display when you boot up your operating system or minimize active windows on the screen. Also, if you use the dual-monitor function on your computer, you might want to see the same background image on all display screens. This is called "extending the desktop" and it is possible to perform this action in the Microsoft Windows and Apple Mac OS X operating systems.
Stereoscopic 3-D is a technology that allows computer monitors, among other devices, to create the illusion of a three-dimensional picture by presenting each eye with a slightly different image. To play 3-D movies or video games on your computer's monitor, first determine that your current system is compatible with that feature and, if not, by upgrading it.
Connecting your PC to your TV using an HDMI cable outputs your PC's display in the highest quality possible.

Troubleshoot problems with the monitor while using a VGA connection to determine if you can resolve the issues or will need to seek a professional repair person.
If you own an electronic gadget that operates with a touch screen, the type of screen technology can make a difference in the device's performance. According to the EE Times Asia website, most touch screens use what is known as resistive technology. This technology is normally used for high-traffic applications due to its durability and flexibility.
In the language of computing, "refresh rate" is a value indicating the number of times per second that an updated signal is sent from a computer to a monitor. Most monitors and video cards support multiple refresh rates, which you can set by modifying the display properties in Windows. If you select an incorrect refresh rate, problems can result.
A pixel is the smallest screen element on a display device, such as a digital camera screen, monitor or television, which forms the images displayed on a screen. The word “pixel” is a combination of “pix” for “pictures” and “el” for “picture element.” A pixel is can be either liquid crystal or phosphor elements that are energized at different intensity levels to create a range of colors.
It is easy to be confused by the many different three-letter abbreviations and acronyms used to describe the features and components of consumer electronics. These terms often hide the complexity of the technology and make it easier for marketers to use hype or even falsehood to give their products a competitive advantage. For instance, TFT and LED are two terms describing electronic components used in television, computer and mobile device displays that are not competitive, but complimentary technologies.
GPE, or graphics picture enhancement, is a component in your Sony Trinitron monitor that automatically adjusts color, brightness and sharpness settings of presentations, graphics and videos.
