Hi Guys

I've a P2721Q monitor connected to my WD19 docking station, all via USB Type-C cables that came with the appliances. I've updated the WD19 firmware and the firmware and drivers on my laptop. The 3840x2160 30Hz.  My monitor screen goes black from time to time. I've read many of blogs on the DELL site and tried several actions to no avail. The monitor still goes black and comes back on after a second or two.

regards

Dara
