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?
