Can not use shot tracker if connected to external monitor

When connected to the external monitor and using the driving range, it’s no longer possible select the shot tracker.  All you can get is the dispersion (landing dots) display.  

Been a bit disappointed in Garmin.  I’m a big fan.  Use their watches, bike computers, bike pedals, avionics, etc and have always been impressed with the quality of products, support and value for price.  

The R50 has the potential to meet this grade but it feels rushed (to meet holiday buying season no doubt).  Sure would be nice to see a list of anticipated upgrades.  Of greatest concern is the accuracy issue that’s been discussed at this website.   I am just getting back into golf after a 25 year hiatus so I don’t have a good reference but I do want a device that’s close to perfect accuracy at this price.
