Envy x360 15 aq160sa - Unable to detect extended screen

[JWadd]

Hi, I am trying to fix my friends laptop (Envy x360 15 aq160sa) as up until recently she had been using her laptop along with an extended screen via the HDMI port.

Over the weekend, the screen went blank and no signal message appeared.  Checked the HDMI cable and monitor, both worked with no issues on another laptop.  HDMI socket appeared clean although I did give it a gentle wipe dry wipe down.

I have done all the obligatory checks, reboot, uninstall driver (Intel(R) HD Graphics 620), done HP driver/update scan, Intel driver update scan, installed intel suggested driver, updated windows although was current (Windows 10, version 22H2 build number 10.0.19045.6036).  

Looking at the HP website and after allowing it to do a scan, it correctly identified the laptop model, but didn't offer the Windows 10 22H2 as an operating system.  Tried a few Windows 10 options although nothing of note came up, just one driver for w/lan, but no issues there...

When checking the driver log it stated that the Device not started (igfx), with the details:

Driver Name:oem6.inf 

Class Guid: {4d36e968-e325-11ce-bfc1-08002be103318}.

Service: igfx

Problem: 0x15

Problem Status: 0x0

The BIOS version is F.58

I tried to see if there was an option to switch on the HDMI in the BIOS but it looks like HP have prevented access to advanced settings.

I have tried connecting the monitor via the USB-C using a USB-C/HDMI cable and still nothing.

I have managed to do a workaround, using a USB-A to HDMI adaptor, however I, and my friend, would prefer just to use the HDMI socket.

Does anyone know how to fix or if HP have offered a BIOS update or patch to sort the issue out.  It would appear to be a known issue.

Many thanks
