HDMI ports disconnected

[andrea28]

Hello everyone, I apologize in advance but I am a beginner and I also apologize for my English

Anyway, I have an old monitor that I connected to my laptop via an HDMI(laptop)-VGA(monitor) cable
However the monitor is not detected
In particular, if I start a wayland session and run the xrandr command I get the following output:

Quando invece apro una sessione X11, ottengo il seguente output:

My PC is equipped with only one HDMI port, I don’t know why with X11 it detects two

How can I fix the problem and get the monitor working? Thanks everyone and sorry again

[nepti]

Please, do not post pictures of the terminal. Always use a code block for terminal output.

@andrea28

HDMI(laptop)-VGA(monitor) cable

Maybe that’s the cause.

@andrea28

Windows dual boot: Probably

Does the monitor work with this cable on Windows?

Have you checked whether an HDMI to HDMI connection from your laptop to another monitor or television works?

[andrea28]

On Windows the HDMI-VGA configuration does not work

I tried with a TV and with an HDMI-HDMI cable
The result on Linux is that the monitor is detected but there is no signal (for a couple of seconds you saw the screen and then nothing)
I attach xrandr performed at that time:

HDMI-1 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 160mm x 90mm

DP-1 disconnected (normal left inverted right x axis y axis)
HDMI-2 disconnected (normal left inverted right x axis y axis)

As for Windows, the TV was detected but nothing could be seen.
So I don’t know what to think, maybe in this case it’s a problem with the TV but as for my old monitor I think the problem is the cable
Although a friend of mine did the same thing and it worked right away, that’s why I find it strange

[nepti]

@andrea28

I think the problem is the cable

I think so too.

Try connecting your laptop to another monitor via HDMI:HDMI, for example a friend’s. Check with Windows and Linux, if both operating systems do not recognize the monitor correctly then it is possible that the HDMI port on your laptop is faulty.

[andrea28]

unfortunately I can’t currently try to connect my laptop with an HDMI-to-HDMI monitor
However, I tried with another TV and the TV is recognized but the words “no signal” appear on the TV screen.

Could this have something to do with my Nvidia graphics card? I’ve read that some have had problems but for example I can’t find several configuration files, including /etc/X11/xorg.conf.d/xorg.conf

[nepti]

The primary GPU for you is the Intel iGPU and it is also used as the opengl renderer. This should actually work out of the box, especially since according to garuda-inxi the HDMI port is coupled to the iGPU. With the Nvidia card, no external ports are shown in your garuda-inxi, which is a bit irritating to me… does anyone have an idea?

Try installing the optimus-manager:

sudo pacman -S optimus-manager

and thus switch to the nvidia card:

optimus manager --switch nvidia

Then you connect the monitor or TV and see what happens.

btw: why do I suspect that you are also one of the “lucky” HP users where the iGPU + HDMI does not work correctly…

[andrea28]

sudo pacman -S optimus-manager
risoluzione delle dipendenze in corso...
ricerca dei pacchetti in conflitto in corso...
:: optimus-manager-1.5-4.1 e garuda-nvidia-prime-config-2:1.1.6-1 vanno in conflitto. Rimuovere garuda-nvidia-prime-config? [s/N] N

errore: impossibile eseguire l'operazione richiesta (dipendenze in conflitto)
:: optimus-manager-1.5-4.1 e garuda-nvidia-prime-config-2:1.1.6-1 vanno in conflitto

I understand that the package I already have conflicts with optimus-manager.
Do you recommend removing it and installing optimus-manager?

[nepti]

No. Do you have nvidia-prime installed? This should also allow you to switch the GPU.

[andrea28]

it is installed.
How do I make the switch?

[nepti]

No idea, I’ve never used nvidia-prime

Try installing envycontrol:

sudo pacman -S envycontrol

reboot and then:

sudo envycontrol -s nvidia

reboot.
Now the NVIDIA GPU runs as primary GPU.
Then connect the monitor or TV via HDMI and see what happens.

…if I had known beforehand that this would be an nvidia topic…

[andrea28]

I tried but nothing… it doesn’t work, I really have no idea
The HDMI port shouldn’t be damaged otherwise it wouldn’t even detect the connection with the TV or am I wrong?
I attach the output of the command for completeness

Enable ForceCompositionPipeline: False
Enable Coolbits: False
Successfully enabled nvidia-persistenced.service
Operation completed successfully
Please reboot your computer for changes to take effect!

[nepti]

That looks good, did you restart after that?
Post the output from:

[andrea28]

yes I rebooted

output inxi -Gxx

[nepti]

Now it’s correct. Does a monitor or TV now work via HDMI?

[andrea28]

I tried again on the TV and nothing, it doesn’t work

[nepti]

OK. Since the whole thing doesn’t work under Windows either, I’m assuming that the HDMI port is faulty or the HDMI cable.
As I said, test this with a friend with a different monitor and a different HDMI cable (also on Windows).

If you want to switch back to the Intel iGPU:

sudo envycontrol -s integrated

[andrea28]

Okay thanks so much for your help
Unfortunately I can try it on a friend’s monitor in about twenty days, maybe even less and at the moment I don’t have a new HDMI cable
In any case, if I have any news I will write it in this topic
Thanks again for your availability
