Setting up ultrawide (3440x1440) 34" monitor

Question

I've got a Samsung S34J552 34" especially for using with 3440x1440 resolution but looks like it only work at 2560x1080 with Ubuntu 20.04. I tried o add the 3440x1440 profile using xrandr without success (it goes back to the 2560x1080).

In the manual for your monitor they stated that you should be able to use up to 75hz with 3440x1440 using hdmi 2 port. Try it. — Michal Przybylowicz, Feb 10 '21 at 20:08
I used a USB-C cable and it was alright! HDMI didn't work, not sure about the display port. I have an RTX A5500 in my laptop. — Ruthvik Vaila, Jun 15 '23 at 03:01
