The USB C stopped sending video and audio via USBC/HDMI adapter.

[RougeAVG]

I used my laptop with two external monitors, one connected by the HDMI port and a second one using the USBC port  with an USBC - USBA/HDMI/VGA adapter. It worked fine for like 3 months and suddenly the port stopped sending audio and video.

The USBC - USBA/HDMI/VGA adapter works fine with mi Samsung S22 Ultra, letting me conect my phone to the same second monitor I was using with my PC. Also through the USBC - USBA/HDMI/VGA adapter I can use everything I conect in the USBA port of the adapter (both on my phone and my Notebook). When connected to the Notebook, The USBC - USBA/HDMI/VGA adapter sends power but no signal through the HDMI cable. I have used difernt cables and different monitors and nothing works, no signal.

My local HP support told me that the USBC port doesn´t supports sending AV through the USBC port but I used like for three months so it must support it. Also in the specs mentions usbc Type-C Displayport. 

Please help.

USB-C port "7" supports DisplayPort 1.4  video as discussed on page 4 of the users guide.

All you need is a quality USB-C to HDMI cable.  There is no need for a USB2/3 type adapter.

Can you provide a link to any cable or adapter you bought for the USB-C?

You also have the HDMI port so your laptops easily supports two external displays.

The other USB-C do NOT support video.

If there is no signal out of 7 there is a problem with the cable or the laptop.  

Try a lower resolution and refresh rate for all displays.  Maybe there is not enough bandwidth to run both external monitors and the laptops screen.

I understand that the HDMI port of the laptop uses the Nvidia drivers and the usb Type-c the ones for intel. Don´t know if there is a drivers porblem.

About the resolution it olnly shos the option for each detected monitor, and it doesn´t deteect the monitor in the usb c port.

Here is the link to the adapter

The adapter is the correct one to use 

It will only work in the port #7 i

Try the following driver from HP support site, it is dated Oct 19, 2022

If you already tried that one then possibly Intel's Support Assistant might have a newer driver

Thanks for the drivers but, I already have them. I was thinking in a specific driver for the usb c port.

I have tried from the bios, restarting the laptop, factory settings.

Don´t know if from Device manager I can enable o disable something in that port, I don't even know how the port appears in the device manager app. 

Thanks.

This is not good.

Bring up the device manager.  Do you see two monitors? Look at "events" for the USB-C monitor

If the second  monitor does not show up then look in the windows event viewer in "system" for anything suspicious.  It might help to clear all events from both system and applications and then reboot to make it easier to look for anything strange.

Also, when did this happen

What caused the problem in the first place?
Power glitch? Upgrade to windows 11?
Microsoft or HP update? Add a new device, memory, etc?
Have you run diagnostics?
Tap the ESC key after powering on and run at least one pass through memory and disk diagnostics.
If you do not have diagnostics get UEFI diagnostic here.

This is the event viewer for the intel graphics.

This is the one for system.

I see two monitors but they are the internal monitor and the one on the laptop hdmi port.

I believe the problem was after a BIOS update.

[BeemerBiker]

Go into the bios and see if you need to enable the internal video.  If it is enabled, then disable it, reboot, then enable it.

[RougeAVG]

Internal video option not available. Don´t know if there is an advanced BiOS section or how to access it.
