I have a Samsung 20" LCD monitor that is nearly 2 years old.Its LCD panel had developed some dead pixels and so it was replaced by Samsung a few weeks earlier.It had been working perfectly since then,but from this evening the display has started to flicker(i think "shaking" would perhaps be a more appropriate word) intermittently for no apparent reason-it happens once or twice every few seconds and then starts working normally again.I thought it was happening because its DVI cable might have become loose,so i disconnected it from the monitor and fixed it tightly back again,but unfortunately the problem still persists.Can anyone tell me why is it happening?Is the monitor malfunctioning and do I need to inform Samsung about the problem?Does it have anything to do with my graphics card?
and out of warranty. nobody will buy it
