I'm using Anydesk to remotely access a Dell XPS 15 with Windows 11 (not sure if this is Windows 11 specific). Lately, the remote screen freezes when the lid is being closed, as soon as the laptop screen turns off (close lid actions are deactivated in the power setting). A few days ago it used to work or I'm doing something different that I didn't realize.

Please note: it's just the remote screen that freezes, the laptop keeps running and the remote control of the mouse and keyboard still works. When reopening the lid, all movement/clicks done with the keyboard and mouse were executed.

The first time it didn't work I opened the power settings, afterward, it seemed to work, but this doesn't fix it anymore. Is anyone else experiencing this kind of behavior? Is there a fix or workaround except for breaking the ACPI Lid driver or removing the magnet? I also tried to set the presentation mode, but it didn't work.

If and when (as stated above) power Suspension is disabled for the lid closing action, then the issue deals with the display driver not being registered anymore by the machine (and thus, the display picture is not send anymore to the driver and hence cannot be read by AnyDesk).

One way to solve this is to use a bogus HDMI display (a HDMI plug that mimics a display but with no image at all). It works Ok. Link: HDMI Dummy Plug,Headless Ghost, Display Emulator

A 2nd solution is a bit more obscure but doesn't involve using any additional hardware. You need to break the ACPI driver in Windows' Device Manager by changing ("updating") its driver to a non-compatible one (any one from the list). This way the ACPI function will simply won't work and won't turn off the display.

What I did to resolve this issue is to plugged in a 'false' HDMI plug that tricks the system into thinking I have a secondary monitor attached.

Then by setting my monitor setup to "Second screen only" using WIN+P
