Please note that the original image of Wude's render was not so wallpaper-friendly so some resolutions do look a tiny bit distorted, but I have tried my best to keep the SEGA logo above the task bar.

If there are any resolutions you need that I haven't covered, then tell me and I'll make one for you, or you could just you it yourself
