Dual monitor setup (driver issue?)

Absolute linux newbie here. Appreciate any kind of help. Just installed Mint 22 to try it out. I have 2 monitors (1x 1080p 144hz Display Port, 1x 1080p 60hz HDMI) and currently only the 144hz one is accessible in 60hz. Tried a bunch of solutions I found online and got it to work. No idea how cause it took hours and after a restart it was somehow all reset to 0 so here I am again.

drivers I tried from the driver manager:

nvidia 550 driver + restart

nvidia 535 driver + restart

nvidia 560 driver + restart

All resulted in a successful install but no luck on having the ability to configure my monitors. xrandr shows me that I only have one monitor connected and "xrandr -r 144" gives me the following result for that main monitor: Rate 144.00 Hz not available for this size.

Check my display settings and nvidia x server settings app, which is missing a lot of options regardless on which driver I install.

What's the solution here and what other things can I provide to get help? Thanks!

Mint 22 - AMD Ryzen 7 5700X - RTX 3070

Start with the reported Display Settings and NVIDIA X Server Settings behavior, along with the xrandr output for both monitors. Reproduce the dual-monitor setup on Mint 22 and determine whether Cinnamon has a specific defect; the report currently does not identify a file, test, or concrete change that defines done.
