I just got the MHL to HDMI cable specifically made for the Samsung Galaxy S3. Everything seems to work, although it is picky with my HDMI ports on my tv. One works, one works without sound, one does not work.
As for Netflix, mine is working fine on the phone, but when I output it to the tv, it resizes the video to the old tv size screen and not my HD widescreen. Everything else on the phone seems to fill the screen, but Netflix specifically resizes every video I show, so on the phone is it widescreen, but on the tv it is not. I can stretch it on the tv, but that reduces the quality.
Anyone else having this problem? I hope to try this on a different tv, although I wanted it to work on mine. My previous Samsung Charge (with hdmi micro out slot on the phone) connects fine to all my Panasonic HDTV HDMI slots and Netflix shows wide screen fine on the tv.
Thanks for any feedback.
