Windows 10: Frozen screen on my second monitor

Been projecting my main pc to my laptop as a second external monitor for about 2 weeks. All of a sudden the screen projection on my laptop would freeze after a minute or two. Anybody can help me fix this and explain why it is happening? Oh and my PC is in Windows 10 but my laptop automatically updated to W11.

Second Monitor Screen Frozen after Update


Hi,
I have an ASUS Zenbook UX31E. It had Windows 7 pre-installed. I have an ASUS docking station and connect a keyboard and second monitor which is a 19 inch SyncMaster 2023 by Samsung. I bought it in 2009 and it’s not a widescreen, so I have to compromise with the resolution, but it’s fine. My mouse via USB key is Microsoft Arc Touch.
Three days ago I updated to Windows 10 and everything was working well until yesterday. Both screens froze, neither the mouse nor touchpad worked. The cursor was blocked. I think it rebooted. Still unable to log-in. After a few reboots I could log-on with my laptop which is now working normally. The problem is the second monitor. It’s still showing the log-in screen and a frozen blue dot. The cursor doesn’t show and the mouse doesn’t work on it. I’ve disconnected and reconnected. I’ve rebooted loads of times. I’ve disconnected everything, router, docking station etc.etc. Still nothing. The same frozen screen reappears.
When I go via Control Panel to display, the second monitor is not there. When I go into devices and hardwear, it’s not there either.
I’m prepared to buy a new monitor if I was sure it would work as the current one is from 2009.
Any suggestions on how to fix are welcome.

Unfortunately it's not that. My installed driver is a newer version.




Back to the drawing board!

Hi,

For us to properly isolate the issue with your second monitor screen resolution, we would like to know the following:
