Blurry Screen on Correct Resolution with New Monitor
Edit: using Ubuntu 20.04
I believe I'm running XServer and not wayland. By getting my session ID from loginctl which is 2, and running: loginctl show-session 2 -p Type the output I get this: Type=x11.
Been struggling with this for some time. I've tried updating the dpi on my monitor and adjusting for a new mode but the text on my new Msi Optix G24 series monitor (DP-0 connected primary 1920x1080+3840+0) with 144 Hz refresh rate is still blurry, while the text on my previous monitor that I've hooked up to a dual display (HDMI-0 connected 3840x2160+0+0)
Here is the output from xrandr:

After you provided us with the necessary information, you could use xrandr to check if you can change your monitor:
xrandr --output DP-0 --mode 1920x1080 --rate 143.85If that works you should use the nvidia-settings to create a configuration that suites your needs. nvida-settings (that I assumed from your tags) are available if the proprietary NVIDIA drivers are installed (Ubuntu hardware app)
NVIDIA has written some good solution about persisting (i.e make your settings stay for the next boot) the information you need for your monitors. It also explains why NVIDIA doesn't set the frequency of your monitor right.
The conf file produced by this tool should be saved as file:
/etc/X11/xorg.conf.d/21-nvidia.confReboot. In case that configuration is somehow crappy and your desktop won't start, open a terminal (crtl+alt+f2), login and remove that file. The next reboot (the command is ... reboot) should restore you to your fuzzy monitor.
