5040x1050@75hz Possible?

[Aus_Karlos]

Hey guys new to Nv Surround gaming which i think is awesome.
Im currently running 3 Samsung Displays 2243BW + B2240 + 2243BW on 2 GTX280. Gameplay is pretty much smooth with the exception of Crysis for some reason.
In all my games ive locked the V-sync in the Nv control panel to stop screen tearing, but id like to know if i can create a custom resolution of 5040x1050@75hz or 72hz. The display is currently at 60hz. As far as i know these displays have a maximum hz of 75 but with only some resolutions. I dont fully understand how to setup a custom res. I tried setting up one early and it didnt except 75hz. I'm thinking because i left the timmings on automatic?
Hoping you guys can help me out here..
Thanks

So no one here knows how to setup a custom resolution?

Should be doable in the nVidia Control Panel... but Surround does have a tendency to do what it wants at times. Also, I've never found any advantage in running a TFT at 75Hz instead of 60Hz; it just doesn't make any difference as TFTs don't 'refresh' the way CRTs do.
