Sounds like your graphics card is the problem.
If it’s a desktop computer you could replace the card.
If it’s a laptop, you’re out of luck.
CAUTION: I am not an expert.
“Dude! You got a Dell!”
When happened to me they said it was the LSD.
Two computer geeks walked into a bar...
+1 on the graphics card in your PC.
(Also not an expert.)
Can those be replaced by the consumer?
Periodically with great care.
Modern monitors are all made in just a few factories, mostly in China. The chipsets can vary, but most of them meet the VESA standards set for industry, at least superficially.
Try replacing the cables. Whether a VGA cable, or an HDMI cable or a Displayport cable, there is a wide variance in cables that are hard to see. While working for monitor manufacturers, I always kept backup cables, just because. Not often needed, but invaluable when I found a problem during a demo or for a trade show. You would be surprised how often the most generic part was the problem that had to be replaced.
Today most people use a video chip on the motherboard, and only gamers and geeks end up buying the AMD or NVIDIA discrete video cards. But if the problem persists, try another video card, even the one that comes standard with your computer. Heat problems can mess up a video card or the system bus.
Look at this utility to see more about your setup: Moninfo
There are hundreds of videos, classes and seminars to learn this info in depth. The various video standards (VGA, HDMI, Displayport), video encoding standards, copy protection schemes and other issues can make this time consuming.
Start with a different cable, and then work outward from there.
Did 11 yrs as It in a HS, I have always had good results with HP or Acer monitors Square or Rectangle. That said I would agree the graphic card is suspect. Does the Ghosting start right away or over time?
Can you rule out power surges or brownouts?
LCD?
Cable. Didn’t think of that. I am not the OP, however.
Something that happens over time screams “heat” to me. Again, the graphics card can get toasty, especially in an older PC.
I know it sounds obvious, but has he opened the box and blown out all of the dust?
Hook up the monitor to another computer (if you don’t have another computer, ask a friend). Use a different cable. If the problem goes away on another computer, it is probably the video card. If the problem does not go away, it is the monitor.
I WANT A VIDEO OF THAT PHENOMENON!
Seriously...
Need a lot more info. You said a long time...how long? Assuming it’s a desktop, what brand and model is the video card. What resolution is the monitor and what resolution is the card configured for (settings in Windows)? How old is the computer?
No, LSD. It was a joke.
