    Tivo Series 3 HD

    I just purchased a brand new Sharp Aquos 42" 1080P (LC-42D72U). I have it connected to the TV via HDMI. What display mode should I be using when watching TV? I have Time Warner Cable HD & Digital package. Does the Tivo even do 1080P?
    Right now it's using 720P and looks fine.

    Series 3 TiVo's support 1080i.

    See this link for more details.

    Once on the above page, click on the Product Features link, and then scroll to the bottom of the popup window.

    I don't think anything is even broadcast in 1080p, so do 720p and be fine

    I am a bit of a novice regarding HDTV, but wouldn't 1080i give a better/sharper picture than 720p?

    P = progressive
    I - interlaced

    So each frame progressive shows all parts, and interlace shows half of them each frame.

    I bet if you google progressive vs interlaced or something it will explain it better.

    the ideal setting for a 1080p TV is "native". 720p is often the choice for sports and action (which is why ESPN uses it) and 1080i is often the choice when fast moving action isn't a big part of the shots. Let the Tivo record in the preferred format of the channel/show and you will be set.

    Try both, and see which works best for you on that display. I suspect setting the TiVo to 1080i so that the display can de-interlace to 1080P would produce the best results. If you set to 720P the TV will have to re-scale, possibly introducing scaling artefact's.

    Try it & check the same section of a detailed & fast moving HD scene on both settings.
