HP ENVY USB-C-hub 5LX63AA sometimes works, and sometimes doesn't

[RdLeeuw]

Hey everyone,

2 months ago I bought a HP envy x360 13 laptop without HDMI port, so I ordered with it a USB-C hub. I use my laptop for teaching and it is important that I can share my screen when I want. The USB-C hub works, but sometimes it doesnt... It bleeps a few times, I see it is connected but the screen is not shown on the second monitor. When I disconnect it a few times and reconnect it, the hub usually works. This is terribly annoying and consumes time when I want to start up my lessons. Also I borrowed a USB-hub from a friend for a few days from a completely different brand, and it worked fantastic. No errors, so it has to be the hub.

Lastly the hub did not work a few days ago when I wanted to share my screen on my ultrawide 3440x1440 monitor. I grabbed my old laptop with a HDMI port and that did the job. Is there something wrong with the compatibility of the hub, maybe a driver I need to download or is it just broken?

Thanks for your help!
