Windows 10: 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?

:)

 

HDMI port not installed. Recent updates may be the problem.

Hi GeraldParkhurst,

Thank you for writing to Microsoft Community Forums.

Could you please help me with the below information:

1. What is the make and model of the computer?
   
2. Which version of Windows you are using on both the computers? (To check, type: winver in start menu and hit enter.)
   
3. Do you see any error messages in device manager after connecting the HDMI cable?
   

This might have occurred due to some hardware conflicts or driver incompatibility issues. This happens if monitor isn’t getting any input from the currently selected source. To resolve this issue, I would suggest you to follow the
steps mentioned below.

Method 1: Update drivers.

1. Make sure that the cable are connected with correct ends, output port of the laptop and the input port of the TV/External
monitor are connected to the right port.

2. While the cable is connected
open device manager. The problem may occur by the faulty chipset drivers and graphics drivers. Try to update the drivers and check for the issue.

• • Press windows and R key together at the keyboard and type:
    devmgmt.msc
    
  • If you see any display drivers with yellow exclamation sign,
    Update the drivers.
    
  • Reboot the computer once and check.
    

Method 2: Change display settings.

1. Press Windows and P key on your keyboard together. You will see a Project option on the right side of the screen.
2. Select Duplicate or Extend (depends on your requirement) and check.
3. If it didn’t work, try to
   Change screen resolution and try step 1 and 2
   again.

Method 3: Disconnect and reconnect.

1. Unplug all the TV/monitor cables from the HDMI port.
   
2. Unplug the power cable of external monitor or TV for some time.
   
3. Plug the power cable back to the computer.
   
4. Plug in all the HDMI cables to the computer /TV.
   
5. Turn on the device and try Method 2.
   

Hope it helps.

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?

Video port dead and external Monitor not detected after Windows April update

Windows 10 Version 1803

Dell Venue 11 Tablet 64bit

I run mostly Microsoft apps, Office 365. Quicken 2017

There were no changes made to the system, no new apps.

everything ran perfect until the update

after the update the HDMI Video port no longer works.

There is nothing wrong with the cable or the Samsung 65in TV

are no longer recognized by windows, It was still listed in the device manager I tried deleting it but it no longer returns after refresh.

It is still listed under stetting's Bluetooth and other devices.

Updated all Dell drivers, did not help.

Tried to system restore, failed and can't undo that attempt it is stuck.

There is nothing wrong with and of the attached equipment or the computer except that the update Fail's to address the port and detect device.

Poor coding a character must be in error pointing to the mini HDMI port.

NICE WORK MICROSOFT, Someone needs to proof read your code for errors.

Any suggestions ?
