I just bought a 20" Hewlett-Packard LCD monitor. When my desktop image appears during startup, there's a dancing pattern of red pixels in the black areas of the image. They stop after about 2 minutes and never reappear during the work session. I discovered that if I turn the monitor on and leave it for 2-3 minutes before turning on my PowerBook, the pixels don't appear. Is this just a warming up process typical of LCD monitors? Or could there be something wrong with the monitor?
