Using an 1920x1200 monitor with full screen: no problem
Using an 1920x1200 monitor with windowed: downgrades to 1800x1125
There is no 1920x1080 available - maybe because it's a 16:10 monitor?
In windowed mode the border is invisible (outside) - maybe because I've a second monitor?
Thus I'm watching 1800x1125 (16:10) on an 1920x1200 (16:10) not using full screen ...
Why I'm not using full screen? Switching windows and still seeing TWOM isn't possible.
