1) I have a 1920x1200 16:10 monitor.
There are two ways to play. Either set it to windowed mode, or if your monitor can do correct aspect scaling, fullscreen then use any resolution and it will fill the monitor as much as possible (black bars sides or top-bottom). The latter also works if your graphics card and driver can do GPU scaling (correct aspect).

The latter is what I usually do. There are two black bars on the left and right side, but nothing tragic.

There is another solution if you can't do any of the above. Let it stretch. It still doesn't look bad!
