Mac Mini to Samsung LED TV via HDMI

[Bongo S]

My Mac Mini works perfectly via HDMI into a Samsung UA55D800 LED TV but when I plug it into the Samsung UA55ES7500R LED TV I get nothing. What is the difference between these two LED TV's?

Try another HDMI cable. Also, verify that the HDTV is set to the proper HDMI input port.

Is your Mac Mini also connected to another display?

Tried serious HDMI cables and verified Samsung on correct input. Mac mini not connected to any other display

Do you have another display you can test with? What model of Mac Mini are you using?
