Acer H277H monitor is not charging 2016 MacBook when plugged in via USB-C. Is this possible?
This isn't a USB-C compliant monitor so it's not going to supply power.1  DVI, DP, and HDMI don't support power delivery.  Looking at the Tech Specs page for this monitor, it supports:


DVI
HDMI
VGA


To charge your MacBook and connect your external monitor, you need something like the Apple USB-C Multiport AV adapter.



So, you won't be able to charge your MacBook via this monitor because your monitor doesn't support power delivery, but you can have both your monitor and power adapter connected by using this adapter.
