connecting ipad to hdmi
A few days ago I upgraded to an 11" iPad Pro (Model A1980), but I'm having no success in connecting it to a data projector or late model TV (or any similar device) via an HDMI connection. The error message is consistently "No data signal". I am using an authentic Apple USB-C to Digital AV Multiport Adapter with a proven quality HDMI cable. Is there a setting on the iPad Pro that I am overlooking? Is there a known issue impacting on the iPad Pro and HDMI connections? I've researched the issue widely - and every article suggests that it should be just plug and play. I've spoken to the Apple Support desk, but have made no progress. The support person seemed to know less about the iPad Pro than I did and was offering meaningless (and often widely misleading) advice. If anyone can help, I'd be very appreciative - the iPad is a critically important device for me when lecturing or making presentations.
