A backlight problem usually doesn\'t give a sharp line like the top/bottom gray-out
shows. Have you tried the monitor with a different video source (another video
card, or a TV output)? If there\'s a signal line with weak drive, or a power droop
during part of the page-refresh cycle, it could cause such an artifact.
Yes, this is a dumpster dive monitor my son picked up at work. He tried
it on his computer when he first got it and it did this.

When my monitor died on Friday, we pulled it out for use, as it\'s better
than nothing.
It looks like a bad-data-transfer rather than a backlight problem, though:
can you try both VGA and digital inputs, to see if there\'s any difference?
Usually, the display has a flat flexible printed circuit cable, internally, it
would also be worth cleaning and reseating that connector.

If you can do it safely, poking parts and connectors with a stick while powered is
a useful diagnostic (even if the printed circuit board is cracked, that
can be fixable if you find the crack).
The intermittent symptom suggests bad connection somewhere.

 It\'s getting worse now making it difficult to use the computer. Ever
try to watch a video bad monitor on the bad monitor?

You don\'t know what\'s on the video and what is the monitor. Here is the
latest symptom.

I\'m ready to but a new monitor.

 I had a 23.6\" Asus, and the one I\'m trying to us is a 27\", I think
I\'ll go with the bigger one, 27\".

I\'m asking for input on a model. I don\'t play games I generally just
surf the internet, occasionally make a line drawing in Paint

and Save a lot of picture memes in paint. Just want something easy for
the tired old eyes.

That does not look like a backlight problem. The transition between
light and dark is perfectly sharp and horizontal. The backlight can\'t
do that.
 
 Best Buy same price as Amazon.

That\'s not a back light issue. That clear line of demarcation of brightness between the upper and lower segments indicates a bad display.
