Cant change to max resolution or go fullscreen.

[Dnawalk]

I'm still able to change the resolution but it only allows 1080p or lower my actual max resolution is 2560x1440. It also allows me to pick full screen as an option but it stays as a tiny window instead of stretching to fill my screen. These problems don't appear if I use output adapter 0 instead of 1 but the game runs at like 3 frames on that adapter even on low settings.

I know these might be dumb suggestions but just to make sure :
- is your display monitor connected to your graphics card or the mother board? sometimes it happens by mistake and maybe you are using on-board graphics instead of your dedicated graphics card
- are u using a decent cable capable of 1440p display like a display port 1.4 or hdmi 2 ?
- right click on the desktop and see the current active & known resolution by checking the display option
- make sure in the in-game settings display is set to number one if you're using multi display set-up
- use Alt+Enter
- if none of these worked go to the config file called System.xml under this root :
documents / rockstar games / red dead redemption 2 / settings
open with note pad , find the res and change it's value manually to 2560x1440 , save the file and make it read only
- if it also didn't help delete all the files in the same folder
- update graphics driver
- run the game on windowed borderless maybe
- if you're using a port convertor adapter like a dvi to display , display to hdmi etc .. don't because in my experience most of the time they mess up the resolution and image scale

Welp now I feel silly. Had my display monitor connected to my motherboard. Plugging it into the graphics card fixed this issue. Thanks a lot!
