External monitor connection drops after some time #980

Open Appel-flappen opened 1 year ago

Appel-flappen commented 1 year ago

Hi, Connection to my external monitor will start to fail and become intermittent (keeps disconnecting and will only display for a few seconds) after some time of being plugged in. Note this only seems to happen on battery power whilst at or below 50% charge. When charging it does not happen.

Your system information

I just updated and it was happening before the update.

Please describe your issue in as much detail as possible:

Expected behaviour: can plug in external monitor and use it without losing connection regardless of battery level. What happens: after 30-40 mins of playing (mainly Deep Rock Galactic) at around 50% battery the display will cut out and return to the decks display.

Steps for reproducing this issue:

  1. Plug in external monitor but do not charge
  2. Play games
  3. Display is lost after some time.

This happening not just with the steamos. I have Windows 11 on it and this problem happens frequently and reliably when the battery is below 50%. Here is another report: https://github.com/ValveSoftware/SteamOS/issues/1009 And many more on Reddit.

Is anyone looking at these tickets at all? As the AR glasses like xreal are getting more prevalent this issue is going to get more visible. (I'm trying to use it with the xreal Air)

I had the same issue ( #1009 ) with random HDMI disconnections and i figured out, it was the bad quality of the HDMI Females (all) on my TV.

Try on the HDMI (TV side) while its plugged in to find the point where the connection are fine with some direction pressure on the HDMI Male Connector. If you found the best point of established Connection, try to lock of this point somehow. In my case i put a cardbox paper between the HDMI from the Steam Deck and another Connector Male to press the Steam Deck HDMI Male Connector upwards.

I think ppl have many Problems with HDMI Bad Connections related to the Bad Manufacturing Quality of there TV Devices.. but i don't know why is the Steam Deck Connection such sensitive to this? More then other Devices?
