How to add custom resolutions to Apex

@chairrrrrrrrrrrr I'm using a small application called vibranceGUI, which is mainly created to help increase color vibrance while in-game and then reset to normal as soon as you alt+tab or close the game. However, this application can also be used to change the resolution of your screen when opening the game, giving you the option to fully customize any game even if the game itself does not support that specific resolution.

Give it a go, it's allowed and completely safe to use with EAC.
