2019 ATB LWB with executive seats and 10" screens. I think they are supposed to be 1080p. I can't get hdmi to work when plugging in my iPhone using an official Apple lightning to HDMI out adapter. I've tried multiple high speed hdmi cables. Hdmi flashes for a second when I first plug it in then goes away.

Was anyone able to get anything playing over 1080p on those screens? iPhone, firestick, Roku? Can you connect to your phones hotspot from a Roku or firestick? 2023 L460 Range Rover SE P400

I've briefly plugged in a Chromecast with Google TV into the HDMI port and it worked fine.

I plug in a Roku and my daughter watches Netflix. A bit clunky and takes a while for the HDMI handshaking to work. I seem to remember that patience was key and powering things up in the right order was important.
