2016 Macbook 12 inch
Problem with 4K monitors (both Dell and Samsung) when plugged into the 4k HDMI port on the ULTCDL doc.

Both Dell and Samsung monitors ‘flash/blank’ for 1-2 seconds approximately every 60 seconds or so when I first power on. This lasts for a few minutes and then seems to stabilize. (just happened again while typing this)

Love the Dock.
Do not love the black/blank screens.

Anyone else seeing this?
Macbook problem? Dock problem? Cable problem?

I’ve tried different 4K monitors.
I’ve tried different cables.
