Make yourself a basic screen to the maximum of 1.60 because the projo really is not bright. I advise you to take a gain screen but it must be good if you have a Hot Spot.

Yair brought a giant projector - a Sony VPH 600QM. Alon got a vga-rgbhv connector and we now get images albeit doubled. So it seems the resolution from the user manual is low - it doesn't actually list the resolution but there's a horizontal refresh rate max of 15.75Khz and vertical of 50/60Hz. If you do 15750/50 you get 315 which i think will be the max horizontal pixels. vertical pixels is max 900 from the manual - see p.25. If thats the case then its pretty much too low for modern tastes...
