How to Get Rid of the Red Shadow in NVIDIA 3D

Anaglyphic 3D glasses can reduce the color accuracy of the source image.

Many video games use polygons to simulate a 3D virtual world. However, the images are displayed on a flat, 2D monitor, so there is no sense of depth. There are a couple of technologies that allow you to add depth to the 2D images on your monitor. One method displays red and blue shadows of the source image and is meant to be viewed through anaglyphic red/blue glasses. Anaglyphic 3D has the disadvantage of interfering with color reproduction. Another 3D technology that does not interfere with color reproduction uses NVIDIA graphical processing units, or GPU, and glasses with special filters.

Things You'll Need

• NVIDIA GeForce 8 series GPU or higher
• NVIDIA 3D vision glasses
• 120 Hz 3D vision-ready monitor

Instructions

1. Place the 3D vision glasses on your face. If you are using the wireless version of the glasses, make sure you can see the IR emitter and are within 15 feet. This is enough to establish a connection between the glasses and the IR emitter.

2. Access the NVIDIA Control Panel by opening the Windows Control Panel, clicking on Hardware and Sound, and then click NVIDIA Control Panel.

3. Click the item labeled “Stereoscopic 3D” in the left-hand column of the NVIDIA Control Panel. The main page shows settings pertinent to the 3D effect.

4. Check the box marked “Enable stereoscopic 3D” to enable 3D. This 3D mode uses special filtering lenses and GPU technology to create depth in 3D images. Since this 3D mode does not use blue and red shadows and anaglyphic glasses, the color reproduction is more accurate.

5. Adjust the “Depth” slider to bring the 3D image into focus. The right setting depends on the user. Press the button labeled “Test stereoscopic 3D” to display a 3D image. Try to relax your eyes and adjust the slider until you see only a single image. When you focus your eyes with the slider set at the right location, there is a pronounced sense of depth on-screen.
