Need to force a resolution part 2

[fishboi]

Guys,

I got the DVI to M1 cable in the end, and for some screwed up reason, it doesnt support the 1280X1024 res. It overscans it on the projection screen. You may recall that I could get a perfect 1280X1024 resolution on the VGA cable, WTF??:

The VGA cable fits the image perfectly on the 100" screen. The good thing about 1280X1024 is the games (same native as my desktop Viewsonic). I dont need to reset the res each time I want to play a game. I just clone my desktop, and it works great. There is no difference in the movies. 1024X768 games look crap.

So why would the VGA cable broadcast 1280X1024 for fit, and the DVI cable overscans it?? I was also unable to get the 1400X1050 res I was going for with the DVI (which the projector supports).

Thanks!

PS (The Omega drivers didnt support mutiple res's. I couldnt force multiple rez outputs).

PS. The VGA cable isnt long enough, maybe 3 feet, so thats why I need a new cable. I might as well have gone with the DVI to future proof myself, but it doesnt fit the rez like the VGA cable. Why would the VGA work and the DVI not, if DVI is better?
