Resolutions available with a 7900GT

[dern]

I am trying to drive an epson tw-200 projector using an nvidia 7900gt card. The native resolution of the projector is 1280x720 but this mode doesn't seem to be supported by the graphics card and I can't add it as a custom resolution either.

Given that this is a pretty standard resolution for 720p tv am I missing something particularly obvious? I don't really want to choose something close as the picture quality suffers for the HD clips I'm trying to show.

I'm mucking about with this as the basis for building a media pc but it seems odd that the card doesn't support the (fairly low) resolution.

Thanks,

Mark

What refresh rate are you trying to run it at?
Equally, when you connect the PC - DVI, VGA, or S-Video?
Does the PC recognise the new hardware attached? If so, what resolutions are given as being supported?

I'm running a 7900GS on XP with the standard Nvidia drivers and I get the option of 1280x720 for my CRT monitor and Sony LCD TV.
In XP if you don't get the resolution option you want for your display then uncheck the "hide modes this monitor cannot display" check box in the "Display Properties > Settings > Advanced > Monitor" dialog box. You should then get all the available resolutions your GFX can support (although your display may not).

If you can't get the resolution you want with the Nvidia drivers then try Powerstrip: http://entechtaiwan.com/util/ps.shtm
You can set up custom display resolutions using it (helpful for 1:1 pixel mapping on LCD TVs).

Thanks chaps. I'd unhidden all the modes but it wasn't there hence the question. Odd thing was that once I'd lugged the machine downstairs and physically plugged it in to the projector the mode I wanted popped up as an option .

Anyway, looks great now. Downloaded media portal which looks fantastic and games look great on a 72" screen. Just have to build the proper pc for the job now.

Cheers,

Usually the reason for this is that windows believes, rightly or wrongly, that the monitor, or in your case, the projector cannot support this resolution. Strangley though it will usually give you a higher resolution though! It is always a nuisance with HD monitors and the only way I found to get around it was to use and HDMI cable and then lo and behold 1280x720 appeared in my list of available resolutions.
