How can you tell when your computer monitor is going bad?

Answer by  M85 (172)

This varies between digital and analog monitors. A digital screen will start loosing contrast, things may appear washed out and gray. Other symptom is an increase in the number of dead pixels. Analog monitors fail differently: The color balance might be thrown off and they will become dim. Also watch for things burned onto screen.

Computer monitors that are about to die might flicker or display funny screens (offset to one side or skewed, for example). There may be dead pixels on the display. You might also have trouble getting the monitor to turn on or off, or it might just randomly black out for a few seconds.

If the monitor is a LCD model it will grow progressively dimmer until it is eventually to dim to read. If it is a traditional Cathode Ray Tube Monitor it will take longer and longer to start up and they may be odd lines that appear in your picture.

If you start seeing the picture on the monitor shrinking, blinking, flashing, fading, color changing or the text is blurring it might be on it's way out.

A monitor going bad might have one or more of these issues - random lines,dead pixels,dim picture,distinctly incorrect colours,blury images. There are some ripples appearing in different places in screen, it also affected by distortions and it even changes them in some cases. If the computer is restarted after that computer remains the light stays in yellow.
