I just purchased a G70 – now the screen. I am more concerned for the brightness then the size. I like a little light on the side so I can at least see my wife (she is hotter then anything the bulbs will burn). Will a smaller screen, say 72" wide give me a brighter picture.

I think I will by a 4:3 and mask to 16:9 that way all I have to do is worry about the width.

Yes a smaller screen will be brighter.

To figure out HOW bright...

ANSI lumens * Screen Gain = lumens on screen

Screenlumens / Screen sqft = Foot lamberts ( sp? )

9 is minimum for movie theaters
12 is bright movie theater
30-40 is TV bright

Personally I have a 16:9 72" wide with a 1252 so...
200 ansi lumens * 1.2 gain screen = 240
240 / 20.25sqft = ~12 ftlm

I can have a lights on as long as they are draped properly and not reflecting on the screen. It degrades black levels, but it helps for playing games.
