It is possible to force a non-native resolution scaling onto the game via the config.wtf, but it is very often not exactly advisable. 
You’d want to edit the config.wtf file with an editor like Notepad, and look for a line like this (you can add the line, if its not already present):
SET gxResolution “1920x1080”
If you edit the numeric values the game will attempt to display itself according to the chosen values, but please bear in mind that this may lead to quite some visual distortions or even blackscreens if your display screen cannot work with said values.
If the game ends up looking weird, or the screen indeed goes black, please undo the changes you made.
