LCD Monitor & Dead Pixels - Can A Faulty Video Card Cause Dead Pixels In Your LCD Monitor?

Dead pixels are a common, but often unavoidable, part of how LCD monitor displays are manufactured. While technology has advanced and the incidence of dead pixels kept under control, it is not uncommon to find some of those "pixel dots" on a brand new LCD monitor.

But what about video cards? Can a faulty video card cause dead pixels? This was a question that someone actually asked me.

Well, the answer is a categorical "No"

A video card (or DVI card) can't cause dead pixels... BUT the additional features, clarity & resolution of the card can expose any dead pixels that the LCD monitor might have already had.

You can try reinstalling the graphic card drivers if it's a display problem (related to software or corrupted drivers), but dead pixels are always a hardware defect.
