How to fix zoomed in game when using Widescreen (1080p-4k)

[Noob]

When you attempt to change resolutions in MB2 to your monitor's dimensions, you may sometimes run into an issue where your game is zoomed in and seems to not support the resolution. Windows likes to scale apps and programs to better accomodate the resolution, this messes up a lot of games that try to run in the desired resolution. Try the following:

Shift + ~
r_customheight xxxx (eg. 1080, 1440)
r_customwidth xxxx (eg. 1920, 2560)
r_mode -1
vid_restart

If you get the zoomed in error, go into your windows display settings:

Right click desktop and select display settings
Select the display you want to fix
Change the scaling to 100%
