Secondary monitor's resolution is incorrect

English Hardware
1

Hello there! I’m currently using a dual-monitor setup: my main one is connected via Display Port, and correctly at 1920x1080@120Hz; however, my secondary one should be able to be at 1400x900@60Hz, but this particular resolution isn’t even listed. I’m also using the secondary one in portrait orientation.

Here’s inxi -SGaz:

Are you sure 1400x900 and not 1440x900? On my Dell 1680x1050, xrandr lists only 1440x900.

All seems good here using portrait to the right, though using neither Plasma nor proprietary NVidia drivers.

Oh, yeah, my bad. It was a typo.

I’ve seen some posts in this very Forum regarding incorrect drivers and such, thought maybe that was the problem, but it still doesn’t quite make sense to me.

This monitor seems to advertise some strange data. Built in 2048? A time traveling monitor…also the model is not shown correctly.
Maybe something off with this monitor?

Yeah, it doesn’t show it’s data, but it’s an “3GREEN PRO 1953G”.
