how do i make my video card display a custom resolution? im trying to drive a 32in LCD HDTV with 2x7800GTX

thanks in advance!
 
Right now, I have a LCD HDTV that I want to use as a monitor. I need to know what resolution I need to use for this set. It's a 720p set, but if I tell my card to do 1280x720, it seems like it's zoomed in. What am I doing wrong?
 
Your TV more than likely has a native resolution of 1366 x 768, most 720p lcd hdtv's do. Unless your TV reports that resolution, you'll more than likely need to use powerstrip to force that resolution or else you'll never get 1:1 pixel mapping.
 
Three things:

If using DVI out: Forceware 90 series drivers now support 1366x768 (see Table A.2 in the Forceware Release Notes), so Powerstrip shouldn't be needed.

If using VGA out: It is not clear if Nvidia GPUs can/can't do non-divisible-by-8 horizontal resolutions over analogue -- this says no, this says yes but it then talks about TMDS (part of the DVI/HDMI interfaces), so ... ?

Display manufacturer intransigence: In practice, many manufacturers don't want you to connect the TV to a PC and have done weird things to the digital inputs. E.g. see:
