The color on my monitor mv740 comes on at times , then goes back to light gray with faded colors and stays that way for a long time. Why is that?

Could be a bad monitor. Have you tried the monitor on another computer? Could be a bad video card too. Also other appliances too close to monitor. First I would try the monitor in another PC and than go from there.

I would check your monitor cable first. Maybe it is loose or damaged. If that does not fix it, then I would look into checking the video card with another monitor (if avail) or swapping the monitor to another system (does a friend have a laptop). Anyway, I suspect the cable or monitor itself.
