@ChumCugger The computer industry didn't adopt the wide screen standard until around 2008. Windows 3.1 was way back in the 4:3 ratio days. If you can find any Windows 3.1 wallpapers of size 1600x1200 pixels then you can make those work on a modern 1600x900 pixel widescreen.
@danielbsmith however upon looking into it further there do seem to be fan recreations using Blender which I actually quite like as well.
Thanks!
@danielbsmith unfortunately it's actually quite hard to find a good library of old wallpapers like this. The archive I nabbed this image from only had this particular image in 4:3.
Thanks for the tips though! I super appreciate it!
