I was going to make this same topic so I may as well just hijack this one.
I'm almost sold on GT750e based on what I've read. I know it's the right size/distance for the room (not sure about ceiling height). I'm also new to pjs so some general questions.
Something I've never seen brought up anywhere: How is the startup time? I've heard elsewhere some projectors can take a full minute to start up, which would be a serious drawback.
Lighting is another concern. Supposedly this is the brightest projector you can get for the price, yet just judging by pics/footage I've seen it seems to look downright unacceptable with any light in the room. I'd be using a room with no windows so sunlight would be no problem, but I'd at least like to be able to use it under some relatively dim light at times.
A major noob question on projection: Why project onto a white surface rather than black? Wouldn't black, y'know, improve the black levels? or would that be at the expense of destroying the whites?
And would it look good just projected onto a clean, light grey-ish wall, or would a special screen or paint make a huge difference?
