I’d like to know how to use a design resolution of 1920 x 1080 (so that I can manipulate the game as it is an HD resolution) and use any resolution (say it 960 x 540) to project the game, and, in the case the window resolution doesn’t match the aspect ratio, add horizontal bars, one above and one below.
The second case I’d like to implement is to use a game design resolution of 256 x 224 and when the window doesn’t match the aspect ratio, add vertical bars, one to the left and one to the right.
How do I achieve that? I’m kind of lost. I’ve tried configuring display profiles but nothing seems to work.
