I have a cmp 5,1 with sierra 10.12.6, 8 gb of ram, and three days ago, installed 2gb Gigabyte edition of the RX560. I purchased an HP z23n at a garage sale down the street, and was looking forward to a dual monitor setup with my old aluminum 20" cinema on the right. The cinema display is of course hooked up to the dvi port, and the HP is hooked up to the display port. This morning something odd started happening. The cinema display started flickering, once every 7 or 8 seconds. I dont know why. I just want it to stop. ideas?

It was ok, and the flickering just stated this morning?

Did you try single monitor setup?

Is that 7-8 seconds flickering just keep going and never stop?

You could also check your adapters. I had a display port to mini-display port go wonky on me today and it had the same symptoms.
