I am working with a monitor in our offices that appears to have a malfunctioning DVI interface. When the monitor is in DVI mode, even with cables disconnected, there is serious ghosting, artifacts, bleed over and text fuzzing.
However, HDMI seems to be working fine. I'd like to find a piece of software that would potentially stress the internals of a monitor. Maybe something like a digital snow pattern that iterates through all of the possible colors as rapidly as possible, or something like that? Basically, any software that stresses the monitor components, not necessarily the GPU.
