本來我都諗住一起步玩3D, 唔講技術純唔純熟, 最大問題係制式不一, 無記錯係有３種, 而且3d眼鏡又貴(如果同親友一齊睇,咪要買多幾對),
所以暫時唔考慮

In general, 白幕 renders better color than 灰幕. If you have good control of ambient light in your viewing environment (e.g. thick curtain, non-reflective walls & floor, etc.), you don't need 灰幕.

If you don't do 3D, you don't need to get a screen with a high gain (because 3D projection requires much more light to compensate for the light loss after passing thru the 3D glasses). With today projectors' light output level, gain between 0.8 and 1.0 is already good enough for 2D projection (unless you're installing big size screen like 120" diagonal).
