How to play Sigma Fullsreen 4:3 HighRes

I recently found method to steup optimal resolution setting in Sigma. Maybe this will help , because I tried properly set up gilde for 2 days.

In gilde settings :
- empty window mode, captured mouse, window extras
- check aspect ratio, vertical, deskopt resolution
- static size no

That certainly works. It even comes up on the external monitor.

I'd like to get it to be windowed and stretched full screen though. I had it working that way pre-Sigma, so if anyone knows how to do that please post.

Doesn't work for me, I get black bars on the sides of the screen.

Thats how 4:3 resolution type works on HD 16:9 monitor. If you dont have black bars, picture is streched and unnatural .
