Why does my LS32AG550ENXZA have 2 different specs?

On the left monitor, I'm missing the 2048 x 1152 option on my M1 MBP. What am I missing?

Are you using HDMI 2.0 ports from your PC and 2.0 cables?

@tulipz As a troubleshooting step, have you tried swapping the cables at the monitor while still using the same ports on the M1 MBP? 

That would help identify if it is a cable and/or port issue.

It turns out one of my Anker Hub doesn't support 144 Hz.
