[RESPONDED] HDMI expansion not working (at least on Linux)

Community Support
#1

Hi community,

before starting a second support request, I thought I might try if someone around here can help me. The scenario is the following:
I have a Framework Laptop 13th Generation (Intel) and the hdmi expansion card does not work on most external monitors/projectors I connect to. I had contact with support a few weeks ago and they replaced my expansion card, but the error is still the same. So I’m tending to say it is not a HW issue, but I’m not sure, with some bad luck, it would still be possible.

I did the following tests:

  • Various monitors/projectors all with different cabling (even hdmi to vga)
  • Tested the expansion board on all slots
  • Tested with Ubuntu, Fedora, Suse (tried with WinPE but I realized that there a close to no drivers in it, so I don’t know if it works on Windows or not)
  • Several external USB-to-HDMI adapters, which are all working

The dmesg repeatedly shows disconnects:

I even logged the USB port with usbmon, but deciphering it is out my scope:

I hope someone can provide clues?

Hi @BBreinbauer, welcome to the community.

You’ve definitely done everything correctly. If this behavior is happening with the new HDMI card, and for the sake of triple testing the card, try all the other expansion slots, I’d say this is a board issue.

We know you have a replacement card, please test the card on another computer if you have one available. I’d like to make absolutely sure we’re seeing good behavior from the card itself.

Then from your previous ticket email, reply to it and reopen the case and link to this thread. I’d like to take a closer look at what is going on with that board.

Thanks

Hi Mark,
thanks for your kind reply.
I will be traveling next week, but I will try the expansion board on another Laptop when I’m back. Mind, that I tried both HDMI cards on all expansion slots (even twice), so this check was done.
Thanks
