Response time is often an overlooked feature when the average consumer purchases a TV. However, with LCD televisions, it is an important feature to note because of the great effect it has on picture quality.
Defining Response Time
True response time is the measure of time it takes for a pixel to go from black to white, then back to black. This is measured in milliseconds (ms). Be careful, though--manufacturers measure response time differently. For example, instead of black-to-black they may use a gray-to-gray measurement, which is usually a much shorter time. A high response time means blurring and ghosting will occur in fast motion.
Good Response Times
In general, LCD televisions are known to have slower response times compared to other technologies like plasma or even the much older CRT. When purchasing a TV remember, lower is always better. Most LCD TVs sold today will fall between 5ms and 8ms. Some high-end LCD televisions may have response times as low as 2ms.
Choosing the Right Response Time
Fast motion will require a good response time. This means that if you are planning on using the TV for gaming or for sports, a faster response time, 5ms or less, will give you a much clearer picture. If you want to save the cash, however, an 8ms television will give you an adequate picture.
