I have two 4:3 monitors side by side. Both of them are set to 1280x1024. My desktop is extended across both. I downloaded a 2560x1024 image and set it as my background. I went into personalization/etc. and set it to 'Tile' as Google results repeatedly said I should. No matter what I do, tiling just makes four images appear, two on each screen. I'm at my wit's end with this. What am I supposed to do? I'm using Windows 7 64-bit Ultimate. The displays are being driven by a 470 GTX.
