I have a late 2013 macbook pro retina 13" screen Yosemite v. 10.10.5. I have a new Samsung uhd 50" tv. When I connect hdmi to hdmi the only thing I get on my tv is the Display screen. It only shows the grasses nothing from desktop. How do I get this to work?
MacBook Pro (Retina, 13-inch, Late 2013), OS X Yosemite (10.10.5)
