HP Z27 4k

Hi,

Recently bought a HP Z27 4k monitor and really love it.

Its connected via USB-C to my Macbook 15'' and works just fine.

Unfortunately from time to time it seems to lose access to the USB ports in the monitor.

What i have already tried: changed USB cable, the port connection on the mac, reset the monitor, reset SMC/PRAM.

It seems to be a random issue and i cannot reproduce it easily.

Anyone encountered this issue? Any ideas on troubleshooting this further?

Any help will be appreciated.

Thanks.
