Question: Closing lid on MacBook Pro with High Sierra OS, external hdmi monitors got dark

I am using a 2 year old MacBook Pro 13" with High Sierra OS. I have 2 HDMI monitors connected to the Mac. One is connect via HDMI directly to the HDMI port on the right side and the other is connected to a thunderbolt port on the left side with a HDMI -> Thunderbolt cable.


All work fine until the lid of the MacBook is closed then every turns off. Only way I can get the 2 externals to work is by keeping the MacBook lid open.

I've seen old replies on this, but they don't address high sierra.


Anyone else experiencing this?

MacBook Pro with Retina display, macOS High Sierra (10.13.3), null
