No offense, but you just sound like an ass with the little attitude. Did you really search at all? I think not becaue I did a
google search on "samsung microUSB hdmi" and came up with pretty good results. So let your lazy fingers do some typing and figure it out yourself. I don't know and don't care. It's not high on my priority list. Or buy it, try it, post back and return it if it doesn't work. Better yet, email or call samsung and get the word right from the horse's mouth.
And you did ask if it was possible. So if a cable exists, yes it's possible even if it currently doesn't work. Regardless, I don't think anyone has any official word from samsung if it does or doesn't work with the US phones. Kinda dumb though if it doesn't and it should be listed as an accessory for the phones then or have a disclaimer that it doesn't work.
