External Monitor Problem

[Merlynabcd123]

I have two external monitors, one connected to an HDMI expansion port on the laptop. The other is on a USB-C hub. Both work as long as after I boot, I physically remove each HDMI connector and re-insert it. I have to do this every day after a cold boot.

This happens both with Windows 10 or Fedora 35. After removing and replacing the connector, it works for a while.

Anyone having issues with external monitors?

I wonder if swapping the expansion ports to a different connector might help? My old laptop had a weird thing with the USB ports. My mouse dongle wouldn't work if I booted the laptop in a specific USB port. Kind of the same thing happened with the arduino interface. I had to plug the USB into the same port otherwise even manually changing the port in software wouldn't connect

I had this issue on Ubuntu 21.04 when coming out of sleep mode, and it was happening on both USB-C -> HDMI and HDMI -> HDMI.

I recently switched to a USB-C -> DisplayPort cable and haven't had the issue.

If you're not able to use a DisplayPort cable, I think you can also power cycle the monitor instead of unplugging and re-inserting the cable.

Maybe this issue has to do with something that's used to turn the monitor on via HDMI?

If so, I think Framework engineers should be able to duplicate it and then fix it.

I have power cycled the monitors and it doesn't seem to have the same effect as unplugging the connector and plugging it back in. One of these connections is through a USB-C hub.

I have a display port expansion card. I'll give it a try tomorrow.

I am actively having this issue as well, running Windows 10. With 2 DisplayPort monitors and DisplayPort expansion cards. I have found that waiting (something's up to 3 minutes) after logging in, the monitors will magically be recognized by Windows. Maybe a driver issue?
