Hello,
I'm racing online using my Acer Nitro 5 AN515-55 hooked up to an Acer ED320QRS monitor. I'd like to change the aspect ratio from 16:9 to 21:9. When I enter this ratio in the Nvidia control panel custom settings, I get an error that says the system doesn't support this. Any tips? I'm fine with having black bars above and below the screen. The goal is to keep an accurate field of view.
Thanks
