I want to use both my monitors together and to do that, I have used Nvidia's TwinView setting. This setting merges the screen estate of both monitors into one large virtual desktop with a resolution of 2960x1050. This is a problem for some wallpapers, though, especially the ones that are designed for one specific resolution. The best way to use these is by combining them in one large image using an image manipulation tool.
Of course I could use the GIMP for such an occasion, but it is way too much work aligning both wallpapers by hand. And why should I when tools like ImageMagick are at my disposal?
