Question
A couple of days ago, my monitor started having half of the screen go green. I've tried changing the color settings, but nothing seems to be happening. Is my monitor getting old, or do I just need to clean it somehow?

Answer
Purchase some canned air from an office supply store.
Use the canned air to blow out all the vent holes of the monitor.
Unplug the monitor and leave it unplugged for about 1 day.

open the computer case and use the canned air to blow out your case. pay special attention to fans and the power supply.

If you have an add-on video card, remove it from it's slot and reinsert it snuggly.

After about 1 day plug the monitor back in and use the buttons on the front to enter the monitor menu. Choose reset from the menu.

Check function. If the problem persists try the monitor on another computer or laptop. If the problem goes away on another computer you'll need to replace your video card.
If the problem persists on another computer the monitor will need to be repaired or replaced.
