That would be great. The graphics in your theme are generally superb.
Funny enough, my card (EVGA GeForce GTX 570) does have one and only one widescreen resolution on its list: 1280x800. Unfortunately it's 16:10 whereas my monitor is 16:9, so there's still a bit of stretching going on. And it also looks much less sharp than the highest 4:3 VESA resolution it has, 1600x1200, on my 2560x1440 monitor. So I decided to use 1600x1200 with squished graphics, which turns out to be much better looking than when I tried it with 1280x800.
