I have some pictures and movies on my phone. I bought a HDMI cable and was under the assumption that I could display my pics/videos from my phone onto my TV. When I try and put display the pics/movies on my TV it does not work. I push the HDMI button and nothing happens. When I am trying to play a movie the play/ff/pause buttons are all red and do nothing. Is there something wrong with my HDMI port on my phone?
