 Hi John,

 Thanks for the reply.

 Yes, I agree... the resolution is not that great ... but DepthQ is at least
brighter (no need for dark curtains) than our old hunk CRT stereo projector
on the ceiling - and more than 10x lighter, smaller, and cheaper...

 Looking forward to a newer model with higher resolution.
