Test and adjust your monitor from the PC-Doctor Video Devices window. Start this test by clicking the Monitor icon.
Red, Green, or Blue tests: Use the three color tests to help determine if a red, green, or blue color is missing. Click the Red, Green, or Blue button to display an entire screen of that color. If you have a conventional tube monitor, the entire screen or large section of the screen is black if red, blue, or green fails. If you have a flat panel LCD display or a projection device, look for small dots showing up as differently colored dots on the field of red, green, or blue. If the monitor is still in warranty, the manufacturer of the monitor may replace the flat-panel display or projector if enough colored dots are missing.
Use the VESA tests to help determine the following:
- if one area of the monitor is out of focus
- that the colors are not separating
- that one area of the screen is not as bright as the rest
Press the button of the test pattern that you would like to use and visually inspect for problems. These tests make it easier to detect problems, but determining the issue may still be subjective. If you think there might be a problem with the monitor brightness, focus, or geometry, try using these same test patterns (or the combination test) to adjust the monitor. Lastly, be aware that the display image is affected by the type of light and its angle reflecting on your monitor screen. Try to adjust the monitor or the light if needed.
