External screen flickers on and off


#1

Hi,
I’ve got my new triple display docking station. I have connected my all three external screens. But find out that my HP screen now constantly flickers on and off. So it can work for 10 min ok, and then start flicker every 2 sec, then can stop flicker and work ok again for a while. Sometimes reconnecting hdmi cable helps to stop flickers. Other 2 Samsung screens works perfectly.
Screens: HP ZR22w and two Samsung SyncMaster 245b

I’m using beta driver for High Sierra on High Sierra latest public beta, Mac Book Pro 15’ 2017 highest spec.
