To anybody reading this thread that has the issue:
In the graphics options, uncheck 'User Interface In Desktop-Resolution', see if that helps.
If during the game you have a very short resolution list: the game only lists resolutions that match your current refresh rate. For example, if you have a resolution at 30Hz (for a TV p.ex.), it will only display resolutions that can be displayed with that refresh rate. You can change the refresh rate, and then you should see other available resolutions.
