So, I got the HDMI multi port adapter yesterday, hooked it up, and everything looked fine, except it got really warm (not hot) few times. Today I decided to unplug USB-C power from adapter (mainly battery reasons), and noticed that whenever I close the lid adapter stops sending video signal. At first I thought it's my monitor, but than I connected it to my TV, and I got the same problem. I close the lid and picture goes away (sometimes immediately, sometimes after 10-15 seconds). Is my adapter faulty? Here's a video I made: 0:00 Adapter connected to power and HDMI connected to my monitor - everything works fine 0:35 I disconnect the power and close the lid - picture goes away, no HDMI signal 1:15 I reconnect the power and close the lid - everything works fine 1:47 I connect HDMI to my TV and power is hooked, close the lid - everything works fine 2:23 I disconnect the power and close the lid - picture goes away after 15 seconds, no HDMI signal 2:57 I open the lid - HDMI signal is back on TV 3:15 I reconnect the power - adapter refuses to send HDMI signal I tried with multiple cables and multiple combinations, no luck. I could swear it worked yesterday as intended (closing the lid without power would still give the picture), but honestly I'm not sure, I was to excited setting up things edit: Forgot to mention I'm running 10.12.3 and I have updated adapter firmware on the first connection.
