I recently purchased the triple monitor usb c docking station for use with a 2016 macbook pro.
Screen number 1 is connected by hdmi 4k, HP 27ea.
Screen number 2 is connected by dvi , also an HP 27ea
Screen number 3 is connected by hdmi 2k, and is a acer 27ED.
The problem is with screen number 3. It periodically goes blank for a second and then re-appears. Sometimes this will go on continuously, and other times, the screen seems fine.
