Resolution problem

[pedroternis]

I have a monitor like this (Monitor Gaming LG UltraGear™ OLED UHD de 32 Inch y 240Hz / Full HD de 480Hz ­ 32GS95UE-B | LG ES) but when I install the Zorin OS my resolution is stuck with 1024x768 60Hz. I already tried to add new configs with xrandr but didn't work yet. See my xrandr bellow:
randr
Screen 0: minimum 16 x 16, current 1024 x 768, maximum 32767 x 32767
XWAYLAND0 connected primary 1024x768+0+0 (normal left inverted right x axis y axis) 270mm x 203mm
1024x768 59.92*+
800x600 59.86
640x480 59.38
320x240 59.52
720x480 59.71
640x400 59.95
320x200 58.96
1024x576 59.90
864x486 59.92
720x400 59.55
640x350 59.77
The funny thing is I don't have the same problem with ubuntu or POP_OS. Can someone help me?

Thanks for your reply.

First thing I would try is to switch between xorg and wayland. Log out, click username, a cog should appear.

I guess you can't change the resolution higher in xorg as well? Ubuntu and Pop OS may be using a higher kernel version than zorin OS - it may require that you install a higher version on Zorin. This guide works as well on Zorin 17:

How to upgrade Zorin 16.2 to a newer kernel

In this tutorial we are going to explain how to upgrade the Kernel of Zorin to a newer or latest Kernel. The reasons for upgrading are not only to be found in the necessity for latest and new drivers, but as well in better battery-management, as well in better processor-management, as well for developpers in global. Frist we are going to install Ubuntu's Mainline Tool that helps us managing Kernels in a decent and easy to interprete GUI. sudo add-apt-repository ppa:cappelikan/ppa sudo apt…
