Problem with connecting external monitor via Hub Type C

Hi everyone, I have a problem with connection with external monitor via Hub Type C on macBook (using HDMI). It just happened when I use Windows (bootcamp). It is really annoying. Sometimes my macBook disconnected with my monitor and I have to unplug and plug USB type C again. Problem appears more frequent now.

Does anyone have a solution for my problem? Please help me. Thank a lot.

You do not say what exact Mac /model /year /size /retina /touchbar is this ?


The 2016 and 2017 models of the 13-inch MacBook Pro with Touch Bar limit full speed to the two left-side Thunderbolt 3 ports, with reduced bandwidth on the right-side ports.




To redefine port definition Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379


Try a different cable and test, to eliminate a cable issue.

I posted the pertinent information above.


Both the 2016 & 2017 could be configured with sixth- and seventh-generation Intel Core i5 and Core i7 processors, which supported up to 12 PCI Express lanes.
