Just need a quick simple answer to this one - I decided to change my screen size... Thinking about doing a 72" wide in 1.85 format (72X40"). This puts me around 8ft lamberts with my ecp4100 in a light controlled room w/1.3 gain screen material (8ft viewing distance). Will that be enough brightness to look good?


Thanks,

--Eric

Kinda dim. Most of the setups I've seen look to be around 12-14 and people deem those "normal". I run mine pretty low (10-ish) so a full white screen doesn't blow my eyes away.

With that set-up it should be no problem to get 10-13 foot-lamberts reflected. I have had no problem getting that kind of light-output with any crt-projectors on a 80" wide screen.

I ran my ECP 4100 with an 80" wide 16:9 screen. 1.3 gain. With total light control the image was good.


Consider painting the ceiling a dark colour, as well as the surrounding walls. This will help 'light control' in a big way (reflected light from the screen).


Going smaller (72" wide) will give you a satisfying image.

I'm assuming that the spec of 120 ANSI lumens for the ecp4100 is correct. Should I try to go any higher on the gain?
