[SOLVED] Monitor not detected after wake from sleep

Framework Laptop 13
1

System specs:

  • Framework Laptop 12th gen August batch
  • Windows 11 Pro fresh install

Issue:

Laptop is connected to external monitor with USB-C (charging + video)

When laptop goes to sleep, and wakes up later - it no longer detects the external screen, unless I unplug and plug in back the cable.

Charging still works fine.

Any thoughts?

a) Lenovo P27-h10
b) Yes, all 4 affected
c) I have tried different search keywords and read a bunch of topics - none of them seems to be about this exact issue.

Scenario:

  • Ask Windows to enter “Sleep”
  • Move your mouse to wake the laptop
  • Log in
  • Windows 11 DOES see the external display, but monitor shows “no signal” - until I physically reconnect the cable. And in Windows display settings I see the message: “Display is not active” - even though I have “extend” turned on.

You got me thinking about troubleshooting monitor instead of the laptop / Windows itself.

SOLVED: turns out “DP daisy chain” option in the monitor has to be turned on, for some reason…
