Question

External display

I want to charge my MacBook while connected to a monitor / display. I bought the adaptor here:

https://support.apple.com/en-gb/HT207806

I plugged the adaptor into my MacBook (2016 Retina) and then plugged in the USBC power source and the monitor via the HDMI port (connected to HDMI socket in the monitor).

The laptop isn't charging and the display says it has no HDMI connection.

Is the adaptor broken? Or am I doing something wrong?

I can connect the MacBook to the display with my old HDMI - USBc cable and the MacBook charges from the usual USBc power adaptor.

I would love some help if anyone is around - thanks.

Thank you so much, I bought a 100w adaptor from Amazon and it is working perfectly.

Different adapters have different pass through wattage. It is best to get an adapter that actually advises you how many watts are available. SIIG and Belkin typically do.
