Not sure what is the deal but i can do the driving range just fine when my HDMI connection set up is set to "Samsnun DeX" but when i switch to play home tee hero the garmin will flash white instead of green and won't record a shot. if i back out it connects but will drop again when i go in. So i have to switch the HDMI set up to mirror which gives me a letterbox look vs a nice full screen.
