    As the title says

    I have been looking around, at panels, some say HD, some say HD ready, what is the difference?

    Also I have the Panasonic TH-42-PWD6, Can I make this HD buy Buying an HDMI interface?

    If not what benifits are there to ging HD?

    Any help will be greatly appreciated.

    Thanks.

    Hi

    What I think you mean is the difference between HD ready & HD compatible. If this is the case, 'HD Compatible' refers to the device's ability to receive an HD signal - however, it downscales it to fit the panel's resolution.

    'HD ready', however, means that the device can receive HD content as well as displaying it in its true resolution. However, most plasmas and LCDs at the moment only have the resolution of 720p content (1280x720), as opposed to the maximum HD resolution of 1080i or 1080p - both of which are 1920x1080 pixels.

    Hope this helps

    This is actually not completely correct. The requirements for a unit to wear the HDReady logo are:

    1) HDMI with HDCP
    2) vertical physical resolution of at least 720 pixels
    3) support for up to 1080i sources (1080p not required)

    there is more I think can't remember just now...so it is not required for the panel to be of 1080 pixels physical resolution to be labeled HDReady...

    Cheers

    Ah OK - my linguistic skills are pretty bad, but I didn't mean to say it needs 1080 lines to be HD ready. It may have came accross a bit wrong :).

    I think the dodgey bit was 'displaying it in it's true resolution' - which 720p sets don't do to 1080i or 1080p content, whilst still being labelled HD ready. Sorted cheers :smashin: .
