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 workin

second monitor stopped working

second monitor stopped working after windows 10 update???

 

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.

Also, recommend you to refer below link answered by

My second monitor stopped working

My second monitor stopped working tonight. When I reboot the PC both monitors work, I see the start up screens on both but when Windows gets to the log in screen, the second monitor turns off. I have verified both DVi cables are working as I can switch
them back and forth and both monitors work with the main cable. I have looked at the Device Settings and the second monitor doesn't show up nor can it be detected after boot up. Its been working fine for years and I have done nothing different tp the settings.
It just stopped.
