My regular gig requires me to go into old high school gymnasiums, with the usual gym lighting, and ambient light from windows or skylights, and project a presentation and/or video from my laptop and camera, via a Kramer switcher/scaler. (Sometimes DVCPro tape playback, sometimes DVD)
I need to add another projector and I have about 3K to shop with. What projectors should I be looking at? Any experience with the Optoma TX783?
The ambient light issues usually aren't too bad, as I have them black out the windows if it's a daytime meeting. I can sometimes kill some of the overhead lighting. The screens that I usually use are 10.5 x 7 ft DaLite (Rear and front project depending on the room)
I also have 12 x 15 DaLite screen for bigger rooms. Sometimes I use an inflatable Sima screen.
