HP Docking Monitor USBC Cable!

[chazzy2501]

This is getting tough, I bought some 2nd hand 24" docking monitors they didn't come with USBC cables. I have some 27 monitors here so I was able to test them using an official HP usbc to usbc cable.

 

The official cable is £53!

 

The first cables I bought did nothing!!!

 

The second cables I did some spec hunting and settled on these 10gigabit 100Watt https://www.amazon.co.uk/UGREEN-Monitor-Compatible-MacBook-Chromebook/dp/B082X93XY7/ref=sr_1_20?crid=3AZDYLU4NYXG6&keywords=usb+c+65w+cable+4k&qid=1654085586&sprefix=usb+c+65w+cable+4k%2Caps%2C45&sr=8-20

 

but the docking monitor states that it is an unqualified cable, the picture works as does the webcam but it won't charge the laptop... The cable stated that it supported 100w charging more than enough for the 45w laptop.

 

The official cable does charge the laptop...

 

Some thread on hp stated getting a 20gigabit 100watt cable..

 

anyone else fallen into this trap yet? Will I have to stump up £100 for official cables and worry about their cost when they get damaged or nicked!?

The cable you linked to is made to Thunderbolt 3 spec, whereas I believe those monitors would be USB3, which might be why it's saying it's an unqualified cable.

I bought these for staff to connect their Chromebooks with our CTouch screens. I know it's not the same setup, but they work fine and charge the devices when plugged in.

SOLVED!

 

I bought a different cable and got the same result "unqualified cable" message, a picture but unfortunately no charging or 3rd monitor...

 

The Fix! In the monitors menu there is an option to turn off the OSD message "non-HP Cable warning"... This enables full functionality, the cable will work fully, charge your laptop, allow the camera, ethernet, picture, 3rd monitor and not show the message?!?!?

 

This is a selection under the OSD settings!

 

TLDR turning off the OSD message about unofficial HP cables allows normal USBC cables to work fully. (if capable)

just for curiosity I tried an oculus quest 5m optical USBC to USBC cable.... it did not work.

 

 

it would seem that DP Alt mode doesn't work with optical USBC unless specifically designed to do so, in which case they don't do charging or data....
