I have two LG monitors on a dual monitor setup. Recently, the left monitor will not go back on if I turn it off. It flashes what should be seen (desktop) very briefly, for perhaps 1/2 second but then goes off again. So, I changed the monitor and the same thing happens with another LG monitor. The right hand side monitor always works.

So, it looks like the monitor is not so much the issue since even a new monitor doesn't make any difference. Oh, if I turn the monitor off for about 5 hours, sometimes it will turn on ok. Very weird.

Any idea what the issue might be? Failing graphics card or something?

Thanks,

Jon

This could either be a failing graphics card (which most likely isn't the issue if your other screen works), an error in your VGA or whatever cord your using for the failing monitor, or a hardware error. You'll have to use process of elimination to try and narrow down what the issue is.
