Does my Pavilion 14T truly support Displayport and HDMI via USB-C?

[sonaldo]

Hi. HP says that the USB-C port on my Pavilion 14T is:
"1 SuperSpeed USB Type-C® 10Gbps signaling rate (USB Power Delivery, DisplayPort™ 1.4, HDMI 2.0, HP Sleep and Charge)"

However, I cannot get my monitor to wake up when connecting the laptop to a USB-C dock. Charging and USB peripherals all work, just no video.

So I wonder if the USB-C port is really capable of sending video at all, as I know that some Envy owners complained that the HP specs were false.

There may be an issue with the dock, too, but can anyone confirm they can get video out of the USB-C port? I have no other devices to be able to test this further.

Praveenbv, I have the exact same question as Sonaldo. I have an HP Pavilion 14t-dv000 and bought a QGeeM USB-C to HDMI adapter. When I connect to a Dell monitor via the USB-C adapter, the monitor is never recognized and I am unable send any video signal to that monitor.

Are you confirming that the USB-C port on the HP Pavilion 14t-dv000 does support video output via the USB-C port, as the 'External I/O Ports' would suggest on the specs page? If so, should it work with any USB-C to video output (HDMI, VGA, etc) adaptor, or do only certain ones work? I just received my laptop a week ago, so assume that the BIOS and other Drivers and Updates should already be up to date - do I really need to update those as you suggested? I have also seen this issue for many other users and it sounds like either a specific adaptor is needed or else the HP specs are false. Can you provide a more descriptive answer as to how to solve this issue.

Thank you!

Hi Sonaldo! I finally figured this one out! I had the exact same issue in that my monitor would not wake up when connecting my Pavilion 14t-dv000 via a USB-C to HDMI adapter. I was using this QGeeM 3rd-party adapter and I never got it to work.

After trying with several different monitors, I finally ordered new adapters and it worked! No idea why, but somehow the adapter seems to affect whether the laptop recognizes the monitor or not. Two adapters worked for me: this HP one and this 3rd-party one. I can't explain why they worked and the other didn't, but they both solved the issue for me, and were simply a matter of plug-and-go, no software updates needed.

Hope this helps!
