Is it possible you plugged your monitor into the motherboard video output? (I've done this)
I don't think motherboard video would work at all with a Ryzen 5600, as they don't have an igpu at all
Boot from a USB stick with a Live environment on it. See if you get the same issue.
Issue found: I disabled secure boot from BIOS and now I can change resolution and refresh rate. Thanks for the help!
Thanks for coming back and letting others know what your solution was.
When you swapped CPUs, did you remove your GPU? Even if you didn't, are you sure it's fully seated?

FWIW, your UEFI is generally likely to reset with significant hardware changes (system memory, CPU). It's generally fine with video card, disk and power supply swaps so long as it doesn't boot into a stop code as a result.
How does that make any sense?
Apparently PoP! doesn't support Secure Boot. No idea why the system still runs and works apart from loading nVidia drivers though
Huzzah! Congrats
Checked it just now and yes it's properly seated. Checked power cables too and those are good as well. Cleared CMOS and now display defaults to 1024*768 resolution with no way to change it lol
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
