A few months ago, my LCD monitor started acting strangely. It was displaying moving lines kind of similar to what you might expect on a CRT monitor with a too-high refresh rate. Shortly thereafter, it began acting even more spastic, sometimes flickering the width and height to about 1/4 of the normal size, discoloring similarly to when a magnet is next to a CRT monitor, or displaying "shimmers". I'm sort of confused as to some of this behavior, as I thought LCD panels weren't as prone to interference as CRTs. This leads me to believe that it's actually a hardware issue. My problem is, I can't tell whether it's video card or monitor. I tried hooking up my monitor to another computer and couldn't recreate the issue, but that doesn't mean much. I can't put the video card in another computer to test it, because it's on-board. Since on-board video cards are generally pretty lousy anyhow, I'm shortly going to upgrade--but I'll be mad at myself if it's actually the monitor. Any insight?|||I'd say if you tried this LCD on another computer it's probably the onboard video. But have you tried another monitor on this computer? That may give you the double check you need to feel safe getting a new video card.|||It is a motherboard issue. You might be using a very old motherboard. I have the similar issue once but when I change my motherboard, problem solved.|||not software.
probably a cheap intel video chip.
go get a video card, only about $40.
