HDMI Connection to Monitor Suddenly Failed in Windows 10

Sorry in advance for the length description of my issue...

I have a relatively new HP laptop running windows 10 (the device manager shows only an Intel(R) UHD Graphics 605 display adapter) . Up to a few days ago, I had no problem connecting an external monitor to the one and only HDMI port (the laptop is new enough
that the single HDMI port is the only port available to connect an external monitor).. The connection suddenly stopped working this week. The monitor now displays the message "No Signal Found" and then goes to sleep.

I've tried the obvious; powering down both the monitor and the laptop, disconnecting and then reconnecting the cable, then powering on both; to no effect. I've connected the monitor with the existing HDMI cable to a desktop computer and it works just fine.
I've tried using the "detect" display, in display settings after restarting, also to no effect. I then checked if I have the latest update to the Windows 10 operating system, which I do. I also tried updating the display driver. I still have no ability
to use my external monitor connecting through the HDMI port.

I can however connect an old Acer projector that's a VGA device, using a VGA to HDMI adapter, to the HDMI port. So the port is working and the system recognizes the VGA device, but it no longer recognizes either my HP monitor or a new Samsung monitor on
the HDMI port. So, having checked the monitor(s), cable, operating system, device driver, and the HDMI port, I'm at a loss to understand why Windows 10 can no longer connect to my HDMI monitor(s).

I saw similar question that noted there had been an earlier incident where windows 10 recognized VGA devices, but had an HDMI issue. All of the suggested fixes in that thread were tried and described above.

So, does anyone have any other thoughts on what I could try? Or am I stuck waiting for the next round of system and device driver updates to get this fixed?

 

external monitors switch off randomly - possibly connected to Skype for Business usage?

I am encountering a scenario where the external monitors connected to my laptop switch off unexpectedly. the laptop still thinks they are connected (display properties shows 3 monitors) but the only way I have found to get them back to life is to either
(a) put the laptop to sleep and wake it or (b) do a restart.

This happens both

• in the office, when the laptop is docked, in which case the external monitors are connected to display port sockets on the docking station. Inthis case the monitors switch off and will only come back after sleep/wake or restart.
• at home, with an external monitor connected to the HDMI port on the laptop. In this case sometime the monitor will go off for a few seconds then come back, other occasions its the same as (1)
  

The problem only occurs after the laptop has been powered on for some time, and it seems to be connected to using Skype for Business. As best I can recall the monitors only switch off when I am on a SfB call or meeting.

 

HDMI port can't connect to external monitor after windows update June 2024

Im using an Acer Nitro Laptop, and after an recent Windows update on 25 June 2024, my HDMI port doesn't seem to be working (it was working fine). I have tried the usual steps; updating drivers, restoring system. Cable and external monitor works fine when tested with another machine (laptop). Is anyone facing a similar issues?
