I have one of those red wires that has hdmi out and also a charging link included... my old HTC evo 4g lte works with it, but a galaxy tab 3 doesn't? I just get "connect to dock" and i think something about audio it says.. But no video.. I have a s3 mhl adapter but of course that doens't work either.. I am guessing... galaxy tab 3 7" sprint won't hdmi out to the tv with the proper usual mini to big hdmi output cords.. correct?
