Cannot boot to Windows while connected to external display

[PlavorSeol]

When booting up Steam Deck while it is connected to an external display via official Docking Station from Valve, after Windows shows the rotated loading screen, it crashes while showing nothing, and Steam Deck restarts itself and this repeats until Windows enters the automatic repair mode. There is no issue when Steam Deck is not docked, or Clover is disabled or uninstalled.

Step to reproduce

1. Connect an external display and power supply to Steam Deck Docking Station.
2. Connect Steam Deck to the dock.
3. Volume down + Power
4. Boot to SteamOS.
5. Install Clover.
6. Change the default OS to Windows.
7. Restart Steam Deck.

Reproducible environments

• Steam Deck OLED
• Official Steam Deck Docking Station from Valve
• External display: AOC Q32V3S (Q32V3WG5, 2560 X 1440)
• Windows 11 23H2
• I think Clover status includes the rest.

I cant reproduce that behavior as my equipment is different. Im using a baseus USB C dock and a Samsung 1080p monitor.

you can try an older version of the Clover EFI and verify if the odd behavior is gone -

Edit install-Clover.sh in kate / kwrite and change line 60 -

you can use this values - 5160, 5159, 5158, 5157, 5156, 5155, 5152, 5151

I would suggest start at 5159, install the modified script then test.

Hello. I tried all of old Clover versions that you mentioned, and none of them helped resolving this issue. For 5159~5152, the result was same: Windows shows the rotated loading screen, then crashes. I've also seen Windows' automatic repair mode few times during the test. For 5151, the script simply ends with "Error downloading Clover!".

Dors the error happen if you use a 1080p monitor? Could be a compatibility issue somewhere on the hardware that you are using.

[PlavorSeol]

I do not have any 1080p display. However, I also tested with a 4K TV and the same thing happened. This, and that 1440p monitor are only displays I have.
