I'd like to stress test used LCD monitors for problems that may become apparent after they've been in use for a while. I'm looking for those with components that fail because of heat.
To those ends I'd like to set up a workstation that has a live bootable CD that will do something that's someone intensive as far as the screen is concerned. I've found distros that have LCD test patterns, but those are static images. I want something that will show me that a monitor will flake out after an hour of use.
Also, it would be nice if this could be a simple command. This workstation will be used by people who aren't linux savvy.
