First, sorry for my bad English. I've read some reviews of USB-C to HDMI dongle on the Apple website. https://www.apple.com/shop/product/MJ1K2AM/A/usb-c-digital-av-multiport-adapter?page=4 There're many users mention about problem with their external monitor, either flicker or gone blank. I'm not sure weather this problem still exist in the lasses model? Can anyone with that dongle and 2017 MacBook Pro hook up an external monitor? Or if you use another brand of adapter and it's working, please advice me, I would be really appreciated. Thanks in advance.
