I have a 3840-1200px monitor... I'm proud of the fact. The viewing area helps considerably with my workflow. However.
No one designs wallpapers for these resolutions.

Photographs are usually the best option however i'm usually left admiring a piece, releasing that it would make a great desktop, then remembering how wide mine is and how few actually release wall papers at that resolution.

Well, it's for that very reason that all of my wall papers will support these desktop sizes as standard.
3840-1200
3360-1050
2560-1024
2048-1152
1920-1200
1920-1080
1680-1050
1600-1200
1440-900
1280-1024
1280-800
1024-768

I wanna lobby you to do the same, because screen resolutions and desktop sizes will only get bigger and bigger, especially with graphics cards such as ATI's latest 5800 series delievering eyefinity.
