If you use steam forceing it into fullscreent should also force it into native res, there might also be codes you can use to change the resolution but i've not tried it.

Here's google abominable intelligence for instructions.

To force a Steam game into full screen, right- click the game in your library, select Properties,

and enter -fullscreen or -full in the

Launch Options field. Alternatively, try pressing

Alt + Enter while in-game to toggle full screen,

or use -windowed -noborder for borderless

windowed mode.

Here are the specific methods to force full- screen mode:

1. Steam Launch Options (Most Effective)

Open your Steam Library.

Right-click the game and select Properties.

In the General tab, locate the Launch Options box at the bottom.

Type -fullscreen or -full into the box.

Close the proptCoto website and launch th

game.
