Okay, another office question. I want to darken the tint on my lobby, make it moodier, and instead of LCDs do a projection on white walls. Ambient light levels would be like a nice restaurant, light enough to see text, read magazines, but most lighting would be spot rather than flood, so the wall could be pretty dark. The content would be custom edited, black and white, and the contrast and video edited so that it works with ambient light. Any suggestions? I want to keep cost under control, plus it would run Monday - Friday from 9:30am to 5pm....so life is of some consideration. Because of the application (ambient light, black and white with crunchy contrast, film grain) picture quality isn't of top priority! Source would likely be an 1080p Western Digital looped. I have some good space to sneak mount it. There would be no sound (ambient music from a separate source would be used). Any suggestions?
