How to test for weak pixels

[LukeAP]

I've got a new 20" LCD arriving tomorrow, an LG L2000C.

Obviously I'm going to check it for stuck pixels and colour uniformity, but I have also heard of individual pixels being ok on arrival but failing after a few weeks. Is it a good idea to "stress test" the monitor to try to reveal any pixels which may fail early? Perhaps using flickering video or something?

This may help. MonitorTest is a monitor testing program that's allows you to try it free for 30 days.

PassMark MonitorTest? is a tool that allows users to investigate the quality and performance of their computer monitor or LCD flat panel screens. With more people spending more time in front of computer monitors it is important to purchase a quality monitor that will provide crisp, bright images, while reducing the strain on your eyes. MonitorTest displays a series of specially designed images on the screen at a variety of different resolutions and color depths to test for optimum visual performance. Each of 25 different test screens have been created to test a particular aspect of the monitors performance.
