Acer USB C to HDMI Adapter, 4K USB C Hub with 100W PD, USBA 3.0 Port, HDMI to USBC Multiport Digital AV Converter for MacBook Pro/Air, iPad, Tablets, Switch, TV, Monitor and More
A: Yes, you can use an ACER-UC303 adapter with a compatible USB-C cable to extend your screen on the Acer Chromebook Plus 514, provided you have the correct type of adapter/cable and the external monitor has the necessary input port.
Q: Does this work to send video from late model iPhone to tv
A: It does but not in the format that works with the tv. I had to return and get the Belkin one instead. Probably works well to a MacBook, but not for streaming to a tv.
