2: Video test-pattern

If the right part of the above pattern is darker it could have been caused of low bandwith in your video-amplifier in monitor or graphic-card. It will normally not happen with a digital DVI-D (digital) connection between those devices.

Important, to get this test-pattern to work it must be pixel matched to your graphic-card and the graphic-card to your monitor if it's pixel based.

3: Gamma test-pattern

Use your gamma correction (advanced properties for your graphic-card), watch the monitor from such a distance that the line-pattern in background disappear. That grey box that is close to match the background is your system gamma. Normally gamma=2.2 for PC. If it not match this adjust it.

Important, to get this test pattern to work it must be pixel matched to your graphic-card and the graphic-card to your monitor if it's pixel based.

This test-pattern is designed to also work for video and the PAL system 720x576. If you have a HTPC system and can load still-images in it. Try this image to calibrate your system.

The only player I have succeeded to load this image in is the Media Player Classic. The overlay mode and desktop have different controls for gamma!
