Can't get 60hz on Displayport with 4k monitor (PB27UQ - Asus)
Greetings, I recently switched from Windows to Linux Mint and realized that something was off. I couldn't get 60hz no matter what I tried. I tried downloading the latest graphics drivers and I can't switch from 30hz to 60hz in Display or Nvidia X Server Settings though my monitor supports it. Help would very much be appreciated.

Re: Can't get 60hz on Displayport with 4k monitor (PB27UQ - Asus)
The xrandr info does confirm what you are seeing.
The only suggestion I have is to try the Nvidia-450 driver and see if that provides the higher refresh rate.
There are others on the forum who are better with this type of issue than I am. Maybe they will be able to provide a better solution.

Re: Can't get 60hz on Displayport with 4k monitor (PB27UQ - Asus)
Some error must have been made. The log should list a lot more info on video modes. The xorg.conf file was created but perhaps it has an error. Open the file and post it’s contents:
Did you log out and back in before uploading the file?
xed /etc/X11/xorg.conf

These lines are in the log:
Open the xorg.conf file:
Remove all the lines and then add these:
Log out and back in. If the 60 Hz refresh rate is not used, then upload the Xorg.0.log again.

Re: Can't get 60hz on Displayport with 4k monitor (PB27UQ - Asus)
That didn’t work. My screen just shut down when I logged down so I restarted and and after I restarted I chose Linux mint again and the screen still shut down. On the boot menu log thing it said something like “frequency can’t be used” before the screen shut down. Idk how to get back into my machine now.

Press Ctrl+Alt+F1 to enter virtual console tty1. Use this command to remove the xorg.conf file and reboot:
If you can't enter tty1, then select Advanced options > Recovery Mode at the GRUB boot menu. If no menu shows, then hold down the Shift key while starting, or keep tapping it, or tap the Esc key. In the menu, select “root - drop to root shell prompt ” and press ENTER. Press ENTER again.
Use this command to change the file permissions to read and write:
Remove the xorg.conf file and reboot:
This info is extracted from the monitor’s EDID, which comes from the xrandr --verbose output:

Try repeating the previous steps in creating the xorg.conf file but use these lines:
sudo rm /etc/X11/xorg.conf; reboot

Re: Can't get 60hz on Displayport with 4k monitor (PB27UQ - Asus)
Sorry for the late reply. I’m not sure you’re still here but I kind of gave up trying after the first error but now I decided to try again but I’m sorry to say that the most recent solution you gave me didn’t work either. Thanks in advance if you still want to help me. I guess I have to get used to a blurrier resolution on my screen until new drivers hopefully will fix this problem, whenever that may be, or maybe I will just switch back to Windows for the time being. Thanks for everything that have tried helping me through so far.

Repeat the steps in my previous post and upload the Xorg.0.log.

I don’t understand (`_´)ゞ. I’m so frustrated right now. I even got a new 3070 graphics card and re-download both Linux Mint and my graphics drivers and that didn’t help it either. I really want to enjoy Linux since I hate Window’s spying.
