So I recently got a new computer which has an AMD GPU and I also have a bunch of old games. I tried playing this one old game called Speedy Blupi II that came out in the early 2000s and it was stretched. I did not like the look of it being stretched because it didn't look right and it made the game blurry and I want to make the game have black bars. I tried looking all over the internet on how to fix this problem but all I got were results to fix it for CS:GO which didn't work for my game.
My GPU is an AMD Radeon R9 360
My computer is a Dell Inspiron 3656
There is a picture of my Display Tab in the AMD settings.
