    I've looked through this forum but haven't found a lot of information on how to display HD clips on a Panasonic 42PV500D.

    The Panasonic has a native resolution of 1024x768 which puts it at a non-widescreen aspect.

    There are two inputs of interest.

    a) RGB input which accepts a normal PC signal up to 1280x1024 (reformatted I assume)
    b) HDMI input which accepts 720p and 1080i

    I have an Sapphire ATI Radeon 9600 XT on my PC with DVI and RGB outputs. I would have assumed I could somehow use a DVI -> HDMI converter to allow me to connect to the Panny but a line in the manual made me think twice.

    • This input terminal is not intended for use with computers.
    • 720p/1080i signals will be re-formatted to view on your display.
    • If the external devices have the aspect adjustment, set to 16:9.

    I assume that the RGB connection is useless for HD because of the aspect of 4:3. Has anyone successfully connected their PC to a PV500D via the HDMI connection? If so what's the best way to do it?

    If you can get your PC to generate a 720p HDMI signal using Powerstrip (if your ATI drivers don't support 720p without it) then it should be fine - effectively you get your PC to emulate and HDTV source, rather than your display to accept a PC source.

    Also worth remembering that plasmas often have non-square pixels - hence the 16:9 image is created on a panel with a resolution that isn't 16:9 in square pixel terms.

    When I said 4:3 aspect I meant the scaling of standard 4:3 VGA input. When I plug a PC into it I get my 1024x768 resolution stretched over the width of the panel. So although the display is widescreen it is actually stretching a 4:3 picture over it. Since the HD demos I have are 1280x 720 (16:9) the direct RGB connection won't work (1280x720 is not listed as a supported resolution in the manual for the TV). I'll have a look into the output modes in the drivers I have to see whether I can output HDTV via the DVI out and connect up via a DVI->HDMI adapter.

    Anyone got a good recommendation for a DVI->HDMI adapter?
