Re: 144hz troubles with an RX580

Did you connect the monitor to the Windows PC using the DVI connection? Have you tried an HDMI connection? Use this command in the Terminal to remove the monitors.xml file, if it exists. It’s not needed and will conflict with the next procedure: rm ~/.config/monitors.xml Use this command to create a...

Re: 144hz troubles with an RX580

This line is from the monitor’s EDID: Monitor ranges (GTF): 50-150Hz V, 30-160kHz H, max dotclock 330MHz The maximum dot clock (pixel clock) is 330 MHz. The reduced blanking mode was using a 346.50 pixel clock. Using cvt12 lowers the pixel clock a little more but still is too high: ./cvt12 1920 1080...

Re: 144hz troubles with an RX580

I'm correct in using DVI-D-0 for the --output flag, right? i.e. xrandr --output DVI-D-0 --mode 1920x1080_143.98 Yes. I assume you used this command before that: xrandr --newmode "1920x1080_143.98" 346.50 1920 1968 2000 2080 1080 1083 1087 1157 +HSync -VSync Use these commands and post the output: i...

Re: 144hz troubles with an RX580

Could not using --reduced with cvt be causing issues? Might I have better luck using gtf to do the calculation instead... The cvt tool can generate reduced blanking modes for 60 Hz refresh rates or multiples or it. The gtf tool cannot generate reduced blanking modes. It was designed for older CRT m...

Re: Screen resolution limited

So it appears that the X.Org X display server won’t allow the 2560x1440 at 60 Hz refresh rate to be used but will allow a 50 Hz rate. Restore the xorg.conf file: sudo mv /etc/X11/xorg.conf.old /etc/X11/xorg.conf Log out and back in. Open the Display program and set the correct resolutions. You can m...

Re: Screen resolution limited

The xorg.conf file will have to be used, along with a script to use when changing GPUs.

One question. When you previously used that config file, was the 2560x1440 resolution in effect after logging out and back in, or did you have to enable that resolution in the Display program?

Rename the xorg.conf file: sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old Create the 20-monitor.conf file again: sudo touch /usr/share/X11/xorg.conf.d/20-nvidia.conf Open the file for editing: xed admin:///usr/share/X11/xorg.conf.d/20-nvidia.conf Add these lines: Section "Monitor" Identifier "Mon...

We are not done yet. That xorg.conf file has to be removed when you switch to the Intel GPU. I will post some additional info shortly.

Does using this command correct the resolution:

Was the black screen on just the external monitor? If you have not made any changes or restarted since your last post, then upload the Xorg.0.log.old file, not Xorg.0.log : cat /var/log/Xorg.0.log.old | nc termbin.com 9999 Then do the steps below in a separate post.

These lines from the log explain why the 2560x1440 mode was not used. The PixelClock for that mode is too high.

Re: Monitor config lost after reboot

If you change the monitor settings in the Display program, then they should be saved in the monitors.xml file. If you make the changes in NVIDIA X Server Settings, then you need to open the Display program and click the Apply button.

Re: Screen resolution limited

Right now the monitor is connected to the VGA port. The EDID info lists a 1920x1080 maximum resolution. Would you connect the monitor to the HDMI port and post the output of xrandr --prop I assume the monitor brand is BenQ ? What is the model number?
