    I'm pretty sure this is a restriction of the display standards used in the HDMI ports. I think they're designed to only use the specific TV resolutions, i.e. 1920x1080, 1280x720, 720x576, etc.

    1360x768 is a PC-specific resolution & there is your problem...

    oh right i see, are all TV's like that, as hdmi can only input 720p 480p 1080p and etc, or is it just the LXd70?

    I would think most TVs are like that, although I'm only really experienced with the Panasonics in that department...

    I also can't output at 1366 x768 via HDMI. However, there is a method of outputting at 1366x768 if you have a nvidia card, where you can create custom resolutions.

    What about Sony sets, do they accept 'PC signals' via HDMI or do I have to send 'video signals' instead?
