I recently bought a new HannS.G 22Inch widescreen TFT monitor and it displays a 1 pixel width vertical line of varying colours from top to bottom, which overprints the entire display, however it only shows up in the operating system, i.e.not in the bios at startup. The line is on the right hand side and does disappear and reappear randomly, but not with a restart. I have used it on two computers with the same effect.
Any ideas would be much appreciated
Cheers
