    I am having problems connecting my new MacBook pro 13" to my LG HDTV 37" (720p).

    Previously, I connected my 2008 MacBook Pro 15" to the same 37" LG HDTV (720p) using a DVI to HDMI cable with no problems whatsoever. I've been doing this for a while without any issues (watching Netflix through Boxee, and other content through Hulu desktop, using Rowmote to control from my iPhone, etc.), although I had to connect audio to speakers separately.

    So when I recently got my brand new MacBook Pro 13", naturally, I wanted to do connect it to my TV. So I bought a Mini DisplayPort to HDMI Adapter, which also supports audio according to other threads on this site, and connected it to the TV.

    Primarily, I wanted to see if this new set up would support audio through the HDMI, but unfortunately, I am not even able to get a video signal on the TV.

    My MacBook Pro recognizes the display as an LG TV with a 720p resolution, and the TV actually shows a mirror of my computer for s split second before turning black and saying "No Signal". I spent a while experimenting with the resolution and refresh rate to no avail.

    Why was I a able to do this with my 2008 MacBook Pro, but not the new one?

    Anyone having similar issues? Any suggestions?

    HDMI between MB Pro 13" mid 2010 and LG TV

    @cmurder: did you solved your issue? I have a MB Pro 13" mid 2010 and LG TV 32LC41 and I am experiencing the same issue as you do/did. I have a Mini DisplayPort to HDMI adaptor and an 1,5m HDMI cable. Connecting my MB Pro to a Samsung Display on its HDMI input works perfectly. I concluded that the HDMI cable and DP-HDMI adaptor should be fine to transmit the video signal.
    When connecting to the LG TV, the MB Pro detects it. When I gather the window in the Display preferences, the window names are "Color LCD" and "LG TV". I tried every resolution and frequencies combination without success. The TV should support 1080p as written in the UserGuide. More Info: I have a HD SAT Receiver which is connected to the TV via HDMI (same cable manufacturer) and video + sound are working fine. So the cable could transport the sound if the MB Pro could. Moreover I guess it is not an HDMI plug/port issue on the TV. I am stuck, please help.

    this is a 2 year old thread I dont think the OP is still working on this(well i hope not) now on to your question, its very confusing what your asking

    can you slow it down a break down what your asking

    if its an audio issue make sure you go to preferences, sound and than output and make sure output is set to HDMI

    if its a resolution issue on your tv, on the tv, in your settings look through the picture settings, on my samsung 40" TV for me to get the best image i had a setting called somthing like "Scan input" or something like that and it made my image fit in the screen nicely

    This the issue/ I have "no signal" on my LG TV but still the MB Pro seems to detect my TV because Mac OS X names de Display preferences window: "LG TV".
