AMD Radeon R9 200 Series resolution issues on 49 inch ultrawide
I have just bought a new ultrawide 49 inch monitor. I own a PC with an AMD Radeon R9 200 Series. Unfortunately, I'm maxing out at 3840x1080 with no better resolution available. I tried downloading new software for my graphics card but was hit with an error - 'driver signature'. I'm not sure what that means.
Generally looking for some advice as I'm unsure if my graphics card is simply not good enough or if it is a driver issue.
