Hello everyone,
I hope you’re doing well.
I experienced a bug for a few months now (hoping it would get fixed), so i think it’s time to share it.
I have an external monitor which is connected via HDMI to my labtop, and it used to be able to be set at 144Hz. Since a few months, it’s now stuck at 60Hz. Now i didn’t use that monitor that often in the past few months, so that wasn’t a big issue for me, but now i think i will use it more often.
Anyway, so i search for similar issues on the internet an i found that issue, in which they used edid-decode to decode what the monitor was sending back to the computer about it’s capabilities.
I’ve search all of the monitors in my system using ls /sys/devices////drm//*/edid and got this:
/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card1/card1-DP-1/edid /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/controlD65/card1-DP-1/edid
/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card1/card1-DP-2/edid /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/controlD65/card1-DP-2/edid
/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card1/card1-eDP-1/edid /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/controlD65/card1-eDP-1/edid
/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card1/card1-HDMI-A-1/edid /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/controlD65/card1-HDMI-A-1/edid
From my testing, the third monitor is my internal monitor (the one of the labtop), the fourth one is my external monitor. The two others indicates ports that aren’t accessible in my labtop (i suppose), and hence are empty.
Then, i ran edid-decode for the external monitor and got those logs :
edid_external_monitor.txt (6.2 KB)
From what i can understand here, it’s said that my monitor does support 144Hz by using custom timings. So that means the problem comes from my system.
I tried disabling secure boot, but that didn’t changed anything. But i’ve noticed that when i used nouveau, the monitor suddenly became more fluid. Now i couldn’t test if it was 144Hz because for some reason KDE Plasma wasn’t loading, but i was certainly more fluild than 60Hz.
So that’s letting me think that there is a problem with the nvidia driver. Does anyone had experienced something like this before ?
Thank you in advance.
