Mostly user wants to connect their Samsung galaxy S2 to TV withought any wire. There is no way to connect without HD cable. First thing remember during connection is, you have compatible HDTV cable. I mean mostly Galaxy users don’t know about the suitable cable for this purpose and result is worst.
I recently review a Galaxy user’s experience about this; they said “when I connect galaxy s2 with T.V via ordinary cable my galaxy batteries dead after that”. So I warn those users who try with some wrong cable. Just ask your vendor related to your purpose.
