Still learning I have been stumped trying to figure out why people use a screen with gain and sometimes significant amounts in a HT?
I figured this would be for bright rooms where light can't be controlled, but I see people with high end PJ's using these?
What am I missing?
A bright room will only make it more difficult to see. You need a room with very controlled lighting such as mine to have the benifits of a High Power Screen. One of the benifits of these is good off axis brightness. My pj is hardly a high end model. It is a NEC 6PG+ CRT projector that I have had forever and never changed tubes on. I used the calculator on projector central and postioned the screen and distance using gamma correction, test patterns on my scaler, and a THX optimzer on Star Wars episode 3. I used to be able to light it up with my DVD player front panel lighting in the back of the room when that was there.
Gain is a tool. Certain situations require higher gain screens. Leonard is right though it is also a preference thing and some people love them others don't. I'll add that some people love their HDTVs cranked all the way up like in the store showroom which is way too bright and over saturated. It's as much preference as anything but mainly it's a tool to achieve the minimum screen brightness for a particular setting.
Also high gain screens are usually retro-reflective, which would preclude a ceiling mounted setup.
Thanks guys.
My PJ is actually within the images' vertical range, but I see you are saying Iwould have to lower it to below midway which is not an option.
