How to change aspect ratio for Widescreen Resolutions?

[lauroon]

Hi guys. I was able now to set the resolution to 4K which is nice, however the image is streched from 4:3 to 16:9 now. Can you bring back the original aspect ratio to have units shown correcty (this means that the view left and right have to be extended).

Then just… don't play at that resolution? It's really that simple.
