Second Monitor Stopped Working

[tomandmr]

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?

Inspiron 7386 2-in-1

Windows 11

Intel UHD Graphics 620

Driver 27.20.100.9664 (from Dell)

Did this happen during the Windows 11 upgrade process or before?

Please download and run the Intel System Support Utility for Windows. Select Everything and then click on Scan. Once it completes the scan process, click on Next and then Save. Pick a name for the text file to produce and click on Save to create it. You can then close the app. Finally, open a response post and then, using the Drag and drop here or browse files to attach dialog (below the edit box for the body of your response post), upload and attach this text file to the response post.

It happened before upgrading to Windows 11.


I just bought a USB to HDMI adapter and now have multi-monitor capability agin.

Not really “fixed “ but I have a work/around!

I have the same problem or even worse.

Since the last update, I never had the chance of using my second monitor again.

Can you help me? I really don't know what to do more. 

I have a DELL XPS 15 - UHD 630

I identified a work around.

Not sure I am comfortable sending a system scan through this portal.

You can send it as an attachment to a Private Message (PM). Address it to @David_G_Intel, the Intel Customer Support agent assigned to this case.

I have been asking for a couple of years now for the Serial Numbers, etc. to be removed from the data collected. AFAIAC, this is a serious privacy violation. That Intel has said that they do not think there is anything wrong is an indication of how poorly their privacy training is being absorbed/applied (or lack thereof).
