- Bad connections inside the monitor, including electronic parts like capacitors, that might be defective
- Faulty or loose cable connections at the PC or video end (check the connector pins)
- Bad video card or display driver (this will require you to reinstall the graphic drivers)
All of these can cause monitor color problems - be it intermittent changes in color, or issues with brightness, size & screen position.
Try degaussing the screen if you're using a CRT monitor & keep any sources of magnetic interference away from the monitor. On an LCD monitor, try running it at the native resolution.
