Question 16:9 + 21:9 Dual setup aspect ratio help

[jam144]

I have recently added one of my old 21:9 monitors to my current setup which already had a 16:9 monitor. The 21:9 monitor is mounted vertically next to the 16:9 monitor, however the 21:9 monitor isn't displaying in full screen. It seems like it's displaying the same aspect ratio as the 16:9 monitor and there are two black bars at the top and bottom of the monitor, I can't find a way to make it fill the whole screen.

Any help would be amazing!!

Have you gone into Nvida control panel and told it to rotate the display?

Yeah and I've tried changing the aspect ratio in Nvidia control panel but that hasn't worked either. Thank you for the help though
