So I have recently purchased a new pc with AMD Ryzen 3 2300x 3.5ghz CPU, Radeon RX 560 2gb GPU. (Windows 10)
I hook it up to my new 34” ultrawide 21:9 LG monitor.
At first when i start it up, the resolution was fine, it fit the screen perfectly. But after installing the driver cd it came with, I have been stuck with 1920x1080, which it recommends, and 3 others that are much worse.
What i’ve tried: updating drivers, 3rd party software that adds custom resolutions, going into ‘All Modes,’ from display settings, and even a full reset of my pc. I have also been on a countless amount of other forums and threads. None have helped much.
How do i get my 2560x1080 back?
Thanks.

If this isn’t enough info I will try my best to get what is needed.
