Detailed description：
Windows update proposed me to install 2.2.33.20 and I did along with a few more Asus updates. However, my HDMI out won't work anymore.
The strangest thing happens: The Windows display configuration interface in fact recognizes the external screen as my third screen (with both screens enabled on the laptop) but sends no recognizable signal to any HDMI device I use. Neither over the HDMI out directly or the USB-C port. Looking at my Nvidia Control Panel PhysX menu I can actually see that it is somehow bugged because only the HDMI out is recognized and my other devices disappear, however that is not what is happening on the laptop itself, the laptop itself only uses the laptop screens.

I have already reverted to Asus drivers for Nvidia and that did not help anything. Reverting the ASUSTek Computer Inc. - System - 2.2.33.20 to either 2.2.18.0 or 2.2.33.0 doesn't work because the installer says the latest version is installed and then quits. If anyone knows a way to downgrade the system, do please let me know.

To be clear: both the HDMI out and the USB-C port are not working and show the same behaviour. It seems to be bugged because of the update so I hope for a fix soon, but I need a rollback possibilty at the moment.

Anyone any ideas?

Is the same problem as mine, problem that I've reported months ago but there hasn't been any fix.

Basically, each time we start the laptop, we get this notification, that asks us to reboot the device. This doesn't have a fix schedule, It happens daily, but if I restart the device multiple times in a day, it may or may not appear. What's for sure is that if the laptop stays close over night, in the morning the error is there.

Do a full shutdown when shutting down the PC by pressing the shift key while clicking on the Shut down button and you'll not get the restart required message the next morning when booting up.
I only got this restart message (on cold boot) because I uninstall the ALED HID driver on every system startup via a task as it's the only way now for me to turn off the LED lighting when on AC power. In the past it was possible to just restart/disable that driver and the LED gets turned off immediately but because there's been a change in the recent drivers that no longer allows you to restart, disable or uninstall any of the ASUS related drivers without restarting the PC and hence we have this problem.
