HDMI to USB-C problem - HP 13-ay0xxx

Hello everyone!

Recently I've been facing an issue connecting to my external monitor via HDMI to USB-C. I've never had a problem before with this monitor before and my laptop (Hp 13-ay0xxx) supports DP Alt mode. The funny thing is when I plug in the cable right during boot or reboot or power off, the monitor gets detected and the screen gets mirrored. But if I plug in the cable after i've booted up or if the cable is left plugged in from poweroff to bootup, it doesn't get detected and the monitor displays "No signal". So it's clearly getting detected and connecting but i'm not sure why it only works during bootup/power off. Please help me fix this!

Some details:
Kernel: 6.6.39-1-lts
Window manager: dwm
External monitor: BenQ GW2480 24"

I've tried a bunch of things:
1. Update (pacman -Syu)
2. Playing around with xrandr
3. Looking through `dmesg` and `udevadm`.

Hope you find something useful in these outputs. Please let me know if you need something more.

Re: HDMI to USB-C problem - HP 13-ay0xxx

just a stupid guess: how much have you paid for the cable and what brand is it?
I have a feeling the issue is caused by the rather simple firmware in the chip in either of the plugs and that for some reason it either outright fails or have issues communicating with the chip in your laptop
could also be a fault of either the chips firmware in your laptop or a driver issue - but the driver is programmed to meet the specs interface and from a HP device although all the marketing crap they do with thier printers I expect it follows the specs, too
also: would love to know if this issue also occurs on windows - but I doubt you have windows installed?
also also: as you mentioned hdmi: usb-c is DP - so there's another conversion required between HDMI and DP - could also be the issue

Re: HDMI to USB-C problem - HP 13-ay0xxx

To answer your question, the cable cost me around 17 USD. But I'm pretty sure it's not the cable as I've used this cable for my macbook with the same monitor. Also, to rule out hardware related issues, I connected my laptop to a different monitor which has USB-C to USB-C support and it worked fine.

The current status is that I can't even connect my laptop to the monitor like before (during bootup). But the adapter DOES show up in the output of lsusb.

Re: HDMI to USB-C problem - HP 13-ay0xxx

it was just a stupid guess - as I had my share of issues with less expensive cables in the past (and was able to confirm in my case it was indeed the cable at fault)
do you by chance have a way to feed in another hdmi source to the monitor to check if the hdmi input works? as the conversion from the DP out to hdmi in is still in question
from personal experience anything related to DP can be tricky as for some stupid reason the handshake often fails when a screen is hot-plug added (although hotplug is part of the spec) and often require a cold reboot of both devices - so it could be possible that when the DP link tries to establish a handshake something at the hdmi part fails and hence the hdcp fails - which results in no output
unfortunately my experience with type-c is limited to it being the charge port on my phones thanks to the EU made it mandatory - but I have no hands-on experience with thunderbolt or dp-altmode

Re: HDMI to USB-C problem - HP 13-ay0xxx

Yes I've used the cable with a Macbook and it works just fine. I believe there's some problem with the way arch is sending signals to the monitor when the cable is connected (cuz I get a "No signal" error from the monitor). Not sure how to manually trigger such signals. Any ideas?

Re: HDMI to USB-C problem - HP 13-ay0xxx

I think this is specific to AMD only as my machine running on intel and bspwm with the same kernel works fine with the monitor.

Re: HDMI to USB-C problem - HP 13-ay0xxx

I'm facing the same issue (or at least a very similar one), with a chinese/no-brand device..

The device works perfectly with my Android phone, for example, I connect it to the USB-C in my phone and less than three seconds after, I can see my phone screen mirrored on my monitor; but it doesn´t work with my Ubuntu 24.04 Lenovo K14 (AMD Ryzen 7 5800U).

The device shows in lsusb this way:
Bus 001 Device 003: ID 214b:7250 Huasheng Electronics USB2.0 HUB
Bus 001 Device 004: ID 343c:0000 xxxxxxxx USB Type-C Digital AV Adapter
Bus 001 Device 005: ID 14cd:1212 Super Top microSD card reader (SY-T18)

But I haven't been able to make it work, and can't find any information about it in the internet.

Does somebody know how can I debug this?

Thank you..

Re: HDMI to USB-C problem - HP 13-ay0xxx

Ubuntu 24.04 Lenovo K14

Arch Linux distribution support ONLY

You'll have to ask on ubuntu support channels .

Note that not all ports with a usb-c connector support video connections, try other ports.

If that fails add the full output of

$ lspci -k
$ lsusb -vt

to your post on ubuntu forums.
