To get 1:1 aspect ratio in different games

[Xin Hu]

After reading many discussions about the benefit of getting 1:1 aspect, I have a rough understanding towards it. Thanks to Drimzi and DPI WIZARD along with other contributors that made 56.25% so useful. However, one thing that I wanna know is 56.25% monitor match is used when the the game type is Vdeg and Horizontal Res, right? But when it comes to csgo where the game type is  Hdeg 4:3, what will the monitor match become? Is it still 56.25% or 75%? I am using 1920x1080, 16:9 monitor.

If vertical mm is used, it's 100%, if horizontal like in the calc it's the apsect ratio division:

4:3 --> 3/4 = 75%

16:9 -> 9/16 = 56.25%

x:y -> y/x = (y/x) *100%
