RX 470 wants to run at 30Hz instead of 60Hz refresh rate

Post by Dukenukemx »

I have a PC hooked up to a HDTV 4k but running at 1080P and I want the screen to stay at 60Hz but it goes back to 30Hz when I either shut off the TV or if I switch inputs on the TV. I can switch it to 60Hz if I run "sudo xrandr -r 60" but it'll go back to 30. Display doesn't give me options to choose refresh rate.

This is what xrandr shows.

Code: Select all

Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-1 disconnected (normal left inverted right x axis y axis)
HDMI-A-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 1538mm x 865mm
   3840x2160     30.00 +  24.00    29.97    23.98  
   4096x2160     30.00    24.00    29.97    23.98  
   1920x1200     30.00  
   1920x1080     60.00*   59.94    30.00    24.00    29.97    23.98  
   1600x1200     30.00  
   1680x1050     30.00  
   1280x1024     30.00  
   1440x900      30.00  
   1280x800      30.00  
   1280x720      60.00    59.94  
   1024x768      75.03    70.07    60.00  
   800x600       72.19    75.00    60.32  
   720x480       60.00    59.94  
   640x480       75.00    60.00    59.94  
   720x400       70.08  
HDMI-A-1 disconnected (normal left inverted right x axis y axis)
DVI-D-0 disconnected (normal left inverted right x axis y axis)
This is what I have in 20-radeon.conf

I suggest removing the monitors.xml file: rm ~/.config/monitors.xml

Use the xrandr command: xrandr -r 60

Open the Display program and click the Apply button. If that doesn’t help, then post the new monitors.xml file:
xed ~/.config/monitors.xml

Also post the output of inxi -SMCGx and xrandr --prop
