second monitor stopped working after windows 10 update???

 

Second monitor stopped working

I have an second monitor which suddenly stopped working. The scond monitor is detected but displays "HDMI no signal"

I have:

- updated the display adapter driver from manufacturer (Dell) - no change

- tried the HDMI cable on multiple devices - cable works

- hooked up the monitor to another device via HDMI - works fine

- tried a brand new monitor - still see HDMI no signal

- hooked the laptop to my TV with the HDMI cable - works fine

- updated from Windows 10 to Windows 11 - no change

- cycled power on monitor and laptop restarting in a different order - no change



Very frustrating as it was working flawlessly for years. Any ideas?

 

I accidentally hit the update button instead of postpone and now my second monitor does not work.

Hello,

I suggest you to unplug the cable from the monitor and connect to the second monitor, and check if it works.

Also, suggest you to follow the below steps, and check if it helps.
1. Press Windows + X, and select Device manager.
2. Check if the second monitor is listed under Monitor.
