Summary: Monitor arrived with broken back lighting. If you turned it off and back on while already attached to a PC a faint green back light would start and you could see windows and stuff, then nothing. This is my first ever disappointment with any PROFESSIONAL model from Viewsonic. We have 5 20-inch VP's at work and they are all spectacular with their high-resolutions, color and crisp dispalys. This model obviously doesn't ship well.
