I just bought my shinny new screen and the last one I bought was 8 years ago.

It's Xiaomi 34" Curved 144Hz Gamining Monitor

On Windows 10, I was surprised to see there is a resolution: 6880 * 2880!!!

enter image description here

Oh dear, I checked the specs of this monitor, but on its official website, it's 3400*1440.

I also checked in Ubuntu 20.04, I do not have that high resolution.

Could anyone explain why this is happening?

Btw, my GPU is NVIDIA RTX 2080 Ti.

One option might be that you have Nvidia DSR enabled. to check: open up Nvidia control panel, go to Manage 3d setting and search for DSR-Factors. in your case 2.00x might be enabled
