ET resolution issue

Sup bois, its been 3 days i've reinstalled the game and i'm going through some settings to get a decent resolution/graphics but for some reason I can not get a fullscreen when I change my resolution, i'm trying to play on 1920 x 1080 and this is what i get when i'm applying the settings : https://i.gyazo.com/c7b7835ae5aa4672a1ae522111c9da50.jpg

seta r_mode -1
seta r_customwidth 1920
seta r_customheight 1080
seta r_fullscreen 1

Theses are the commands I used already. Anyone would know how I could fix that?

thanks :^)
