Tried both, no luck. when I pressed the command , f1 , my lap top screen went blue for a second then back to my desktop. tv scree is black with a "no signal" thing floating around
Hello again, still no luck. Did the pram thing before the gray screen, nothing. the only thing I noticed is when I went to system preferences under "displays" the heading has the model of the T.V. up there . if I unplug, it goes away. When I click on "sound" under system preferences, under "output" my device does not show up which would allow me to click on the device. The TV, "LED 3217" appears only as a heading under "display". This is crazy! I just bought the tv and the cables so they cant be outdated.
