HP Spectre x360 - HDMI via USB-C not working.

PrestonD · ‎01-15-2021

Hello,

I have the HP Spectre x360 (15-EB0053DX).

I'm attempting to connect two monitors over HDMI: one is connected via the HDMI port on the left side of the laptop. The second is connected via USB-C to an HDMI adapter.

However, the USB-C to HDMI connection is not working. I've tried two different hubs, one powered and one not, as well as a USB-C to HDMI connector (no other peripheral connections). So far, nothing has worked. I've tried both USB-C ports; one is advertised as a thunderbolt connection, while the other is not.

The resolution of the monitors are 1920x1080 at 60Hz, nothing high powered or demanding.

I've updated the drivers, Windows 10, and ran the HP support assistant for all updates. It's updated the BIOS to the latest version. I've also run updates for the NVidia drivers.

I've seen other people post about it, so I believe that it should be working. I must be missing something simple at this point.

Any help is greatly appreciated! Thank you.

The specs of your machine is

You should be able to connect 2 external monitors many ways. Simplest way is to

Connect HDMI port to a monitor using HDMI port
Connect USB-C (your machine has 2 ports) to a monitor which has USB-C port (direct, no converter/adapter) and you will get result as a DP1.2 port.

You can daisy chain USB-C port monitors too (ie USB-C to USB-C monitor to USB-C monitor)

Regards.

Hello @Banhien

Thank you for taking the time to respond to my concerns.

Unfortunately, I've already tried what you've described without success.

What I want to solve is why the USB-C adapter is not working.

Windows does see the screen if I open up the Display Manager. However, I am unable to extend to that display.

In the Device Manager, I see that whenever I attach the HDMI, that a generic "Billboard" device does connect. This is leading me to believe that perhaps it's a driver issue?
