Can't set the proper resolution on my RX 5700 XT

I have a desktop pc running ArchLinux for some months, no problems with my display, but after I updated the system some days ago, my machine is setting the resolution to 640x480 when I boot into my XFCE(also other DEs).
Also there is an interesting fact: I can not get my BIOS SETUP output when my PC is turned on and even my bootloader doesn't shows up(refind)

What I tried:

1 - Disconnect and reconnect the HDMI cable - Didn't work.
2 - Set the correct resolution(1920x1080) using a xrandr script like this below:

xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode HDMI-A-0 1920x1080_60.00
xrandr --output HDMI-A-0 --mode 1920x1080_60.00

the output:

xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

X Error of failed request:  BadName (named color or font does not exist)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  16 (RRCreateMode)
  Serial number of failed request:  41
  Current serial number in output stream:  41

cvt command used to get the modeline used above:

cvt 1920 1080 
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

Re: Can't set the proper resolution on my RX 5700 XT

What if you try another output port on your GPU?

Also, this could seem weird, but: shutdown the computer, unplug the cable from PSU and leave it unplugged for about 1 minute (let any residual currents / voltages go away). Then replug the cable into the PSU and start your machine.

Unfortunately my GPU only has one HDMI output and the 3 others are display port outputs... I only have HDMI/VGA/DVI displays here.

I tried what you recommended, I turned my PC off and then unplugged literally everything on it: all USB devices, Ethernet cable, Power cord.... It didn't work sad

P.S. Tarkovsky was a great Director haha

back then.

Please post a current log and also the output of "xrandr -q"

Ok, take a look, please.

xrandr -q
Screen 0: minimum 320 x 200, current 1360 x 850, 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)
DisplayPort-2 disconnected (normal left inverted right x axis y axis)
HDMI-A-0 connected 1360x850+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   640x480       59.94  
   1360x850_60.00  59.88*

As you can see, I can set my resolution to 1360x850 which my display also accepts, but I want a 1920x1080 as I had before...

And the updated Xorg log file:

https://hastebin.com/efuqatuyul.yaml

and there is another issue... I'm not getting any sound from my HDMI output:

Re: Can't set the proper resolution on my RX 5700 XT

There's no EDID

[     6.400] (II) AMDGPU(0): EDID for output HDMI-A-0
[     6.400] (II) AMDGPU(0): Printing probed modes for output HDMI-A-0
[     6.400] (II) AMDGPU(0): Modeline "640x480"x59.9   25.18  640 656 752 800  480 490 492 525 -hsync -vsync (31.5 kHz e)

Could be the output (Tv? Adapter?) or the cable - if you can somehow extract the EDID from the output, you can force it into the system:
https://wiki.archlinux.org/title/Kernel … s_and_EDID

However:

https://bbs.archlinux.org/misc.php?action=rules

So, I connected a cable to my TV's HDMI input and then to my laptop and other PC with an NVIDIA GPU and looking at dmsg, it says the EDID file is corrupted. Ok, so the problem is on my display(TV) side, but if that is true, Why am I able to use my Android TV Box device on my TV without issues? This Android device is able to recognize the 1080p resolution of my TV whereas my PC's with Linux can't.... Any idea?

steambox is the name of my machine, it's not another operating system...

Re: Can't set the proper resolution on my RX 5700 XT

"cable" - or android simply uses the default EDID.
However, since this is SteamOS, it's really hard to tell for anyone here.

It's not SteamOS, dude, steambox is just the name of my machine. And yes, I changed the cable and the problem persists
