Yes.

Why force the projector to accept a mode just because it's native to another
screen? Why not give it what it wants?

You could craft a custom mode, but apparently 1280x720 doesn't exist as a
predefined mode.
Here's some to get you started:
Section "Monitor"
Identifier "SyncMaster"
HorizSync 30.0 - 81.0
VertRefresh 56.0 - 75.0
DisplaySize 406 305
Mode "my_1600x1200"
DotClock 120
Htimings 1600 1620 1632 1652
Vtimings 1200 1221 1222 1223
EndMode
Mode "my_1200x900"
DotClock 70
Htimings 1200 1216 1232 1248
Vtimings 900 930 932 960
EndMode
Option "DPMS"
EndSection

Sure. Most cards have a maximum, and many have a minimum, and for all I
know some exclude certain combinations of X_size and Y_size. Can't be more
specific, sorry.
