Hi all,

We have a large white screen which is 12 feet wide and 8 feet high.

I'm looking to buy a projector which will fit most of this screen.

I think I should be getting a XGA (4:3) projector.  But I wasn't sure if a WXGA (16:10) projector would be better.

Thoughts?

Hi Frank,
12x8 is a 1.5 aspect ratio; 4x3 is 1.33; 16x10 is 1.6. So neither is perfect for that screen, but I would go with WXGA, which is typically 1366x768 (1.78) or 1280x800 (1.6). Regards, Joe

Thanks Joe!  The WXGA projector I'm looking at is 1280x800 so I guess I'll go with that.

Frank,
You're welcome. The world has moved to widescreen format (rather than the old 4x3 standard) so I think that a 1280x800 (1.6 aspect ratio) projector is a good choice and will work very well (although not perfectly) on your 12'x8' screen. Regards, Joe
