My customer has a Hanns-G monitor hz201hpb. It has light diagonal striping everywhere on the background of the screen. You see it when you're on the Internet, in Microsoft Word and everywhere else when you use this monitor. This doesn't seem to be a flaw in the monitor but has been set up intentionally. I believe it is a consequence of the monitor settings because it's there no matter what computer you plug into it and whether you use a HDMI or DVI interface. It's annoying. I went though various settings, pushing buttons on the monitor itself, but saw nowhere that you could change the monitor background. I also have searched but couldn't find any reference to this. Does anyone know how to get a plain white background for this monitor? I don't think it makes a difference, but originally there was an XP machine and now I've plugged a Dell Optiplex Windows 7 computer into it.
