AMD-GPU driver patch to unlock monitor refresh rate
Good afternoon to everyone on the forum. I'm writing through a translator. I have a specific problem related to the driver for the AMD Radeon rx570 8GB graphics card. The graphics card is designed for mining and has one DVI-I output on board for connecting a monitor. By default, 1080p resolution has a monitor refresh rate of only 60 Hz, but my monitor supports a frequency of 180 Hz. On Windows, I used a special patch that removed the limitations of the driver for this resolution and the refresh rate was 180 Hz and everything worked smoothly without any comments. The patch is called AMD/ATI Pixel Clock Patcher. Is there a way to remove the limitations of the graphics card driver on Arch?

Please install read-edid from [extra] repo .
As root / with root-rights run and post the full output of
# get-edid | parse-edidThat will show us details about the capabilities of your monitor.
Are you using X or wayland ?

I guess the 5 is a typo and should be 6 ?
You will need a custom modeline to get that refresh rate. cvt12-git shows these options .

$Its values are within your monitor specs and don't need reduced blanking OR interlacing.

I'll have to search how to change modelines for plasma wayland .

Re: AMD-GPU driver patch to unlock monitor refresh rate
Please quote only relevant parts of posts. Quote full posts makes the thread less readable/hard to follow.
https://community.kde.org/Plasma/Waylan … ant_Issues and https://bugs.kde.org/show_bug.cgi?id=456697 confirm neither wayland and plasma-wayland currently have a method to change modelines .
https://wiki.archlinux.org/title/Kernel … s_and_EDID describes a method to override the edid information from the monitor .
Use get-edid to get the raw file, edit it with https://aur.archlinux.org/packages/wxedid .
Changing the values for 1920x1080 to those calculated for 1920x1080x160 is probably the easiest approach.
Is the ADC 27G15N the only monitor you use ?
If not, you will have to ensure only that monitor will use the new edid.

Re: AMD-GPU driver patch to unlock monitor refresh rate
i'm use only AOC 27G15N.
Please, need more info for generated and setting up new EDID. Thanks.

Re: AMD-GPU driver patch to unlock monitor refresh rate
It's a lot trickier then I thought, using a custom modeline on X is so much easier.
Are you willing to switch to running kde plasma on X11 ?

Re: AMD-GPU driver patch to unlock monitor refresh rate
You can straight up copy the relevant edid out of /sys/class/drm/card*/edid (or open it in wxedid), then inject it following https://wiki.archlinux.org/title/Kernel … s_and_EDID
Which of these steps is an obstacle?

Re: AMD-GPU driver patch to unlock monitor refresh rate
actually editing the EDID.
I've looked further into it and am confused.
There are 2 types of entries with resolution data :
DTD (Detailed Timing Descriptor) and STI (Standard Timing Information) .
STIs appear to describe VESA modes, while DTDs show information that looks like the values in modelines.
wxedid includes a DTD constructor that does show a corresponding X modeline.
That suggests that the modeline needs to be converted to a DTD that is then added just below existing DTD entries.
Can incorrect values in edid damage a monitor or videocard ?

As my wayland knowledge/insight increases the probability of switching to it decreases.

Re: AMD-GPU driver patch to unlock monitor refresh rate

Certainly not the GPU since it'll have to filter any EDID against its own capacity, but not all panels sanitize modelines (there was a patch to more aggressively filter modelines in mesa or X11 like a year ago because apparently some notebook panels took damage because they allowed to be run out of spec - which might actually run you into a crt error when trying to add the modeline w/ xrandr)
@sovid, have you tried to add the modeline w/ xrandr?
And just as precaution: Can we get the full edid decoded?
for OUT in /sys/class/drm/card*; do echo $OUT; edid-decode $OUT/edid; echo "================="; doneYou'll need https://archlinux.org/packages/extra/x86_64/v4l-utils/

Re: AMD-GPU driver patch to unlock monitor refresh rate

On X11, what's the output of "xrandr --verbose" (running this on wayland is pointless - you're talking to an X11 emulation only there)
Also please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General (the file, don't copypaste the completely random example in the blue box)

Re: AMD-GPU driver patch to unlock monitor refresh rate
the file, don't copypaste the completely random example in the blue box
What am I supposed to do w/ that tail?
However:
xrandr --output DVI-D-0 --mode 0x5dDoes the 120HZ mode work?
Can you btw. use a display port connection?
DL-DVI is limited to 330MHz, so unsurprisingly the 440MHz modeline will get filtered there and I'm not sure how you'd do this on windows except
1. windows lied
2. you were using an interlaced mode
DVI cannot transmit 1080p@180HZ

At 120Hz there are artifacts as if the image sharpness has increased along with blurring. And yes, the video card has only one DVI-D output

Errrr… wut?

Errrr… wut?
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-1 disconnected (normal left inverted right x axis y axis)
DisplayPort-2 disconnected (normal left inverted right x axis y axis)
HDMI-A-0 disconnected (normal left inverted right x axis y axis)I meant, they technically all could™ be not wired to any jack, I guess. Which kinda sucks.
