I cannot get my HDMI out to work. The mhl adapter is connected between the phone and the HDMI to my tv, and it is also plugged into the wall charger. When I plug it in it asks what USB I want to use and I say media player, but no matter what I do I cannot get my tv to recognize anything, It just says no signal. I have tried on several tv's with three different HDMI cords. My tv is a VIZIO that is less than a year old. I went back to the store and replaced the MHL adapter but it didn't change a thing. Has anyone else had this problem? Is there anything I am missing? Any settings that need to be changed? Any help would be greatly appreciated!
