Protector position and Garmin R10

Hello, 

I recently moved my projector from directly above me about 4 feet forward. Since doing so it seem like if I hit a straight wedge that hits the top of my screen the r10 has a hard time picking up the ball flight. Is it likely the projector is blocking the R10’s ability to track the ball?  The projector is hanging about 18 inches from my 9.5 foot ceilings. 

thanks,

Mike
