When I put the hdmi lead from my projector straight into the R50 there is no picture, it can’t be the lead as it works ok with my iPad. Any help?

I have the same issue, the screen shows Garmin R50 but does not show the actual Garmin screen being displayed on the R50?

I have the same issue, the projector image shows Garmin R50 but does not replicate the R50 display on the screen?

Im usung a BenQ TK700ST

Mine does that until I actually start range session or HTH. 

Yeah well if I'd read the manual you have to select external screen once in a session

The "Approach R50" logo will display until a session for Practice or Home Tee Hero mode is started on the R50. Then enable the display setting to extend or mirror to the external display per the configuration you are wanting. 

I don’t get anything on the screen - no signal.  I’ve tried the cable and projector with other sources and they work.  They both support 1080p.  What’s happening?

This doesn't seem to work with an iPad? I have an iPad on a tripod connected to to the R50 via an HDMI->USB-C cable and I get nothing on the iPad screen at all. I switch the R50 to external display but it says nothing is connected. Is this setup supported?

This doesn't work. I have the HDMI to USB-C cable but nothing registers. I have tried multiple iPads. Can you confirm that Garmin has tested this flow and that the screen from the R50 should mirror to the iPad during practice play?

The Approach R50 cannot be mirrored or cast wirelessly to an iPad. It must be connected via HDMI corded connection from the back of the R50 to the external display directly.
