Ok here is an example.
On the specs of the Optoma EP719 it lists the native resolution as 1024 x 768 XGA. Then it also lists a Max-Resize as 1400 X 1050 SXGA plus. Here is the listing from Projector Central in case I'm not real clear

Hey PH all I see are pics of the screen. Maybe I am overlooking them after all it is early.
I am guessing that the "s" in SXGA means it is stretched?
