Windows 10: My external monitor is no longer being detected after the 24H2 Windows 11 Home Update

Hi there,My laptop has automatic updates running on it and after the last update 24H2 Windows 11 Home, it will no longer detect my external monitor which is connected to my laptop. I have tried going to the manufacturers website to download driver but I keep getting error messages advising it can't be downloaded.

Windows 11 Laptop not able to detect External Monitor LG24GN650

I am not able to detect my external monitor on windows 11 specifically. There is no physical connection issue as the monitor works when I connect it to another device operating on windows 10. There is also not any issue with my Windows 11 laptop's HDMI port as it works on other displays as well. It means the issue is specifically with the LG driver.

I have tried the following methods to solve the issue but was unsuccessful:

1. Updated intel and nvidia graphics driver
   
2. Updated Windows 11
   
3. Updated display driver from Device manager
   

As the monitor was not able to auto-detect I tried running the monitor driver exe file but it was showing error "Monitor is not LG manufactured"

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 ?
