    I've had DisplayConfigX and my HDTV "working" for a while now... but I'm disappointed in the resolution (1208x676). My TV supports 1080i (I know this because my cable box outputs at 1080i, and the default (overscan abundant) 1080i resolutions work), however when I set DisplayConfigX to anything relatively close to a 1080i resolution, all my TV displays is a black screen. Has anyone else had this problem and been able to fix it? Any help will be greatly appreciated.

    TV Specs:
    Philips 32" LCD HDTV - 32PFL5332D
    Native resolution 1366x768

    Your TV has exactly one resolution: 1366 x 768. It, like all LCD, plasma screen, and DLP sets, is a fixed-pixel set. Your set supports 1080i input because its scaler converts the signal from the source to its native 1366 x 768 pixel count. This is how all HDTV sets work. I don't quite know what to make of your 1208 x 676. It may be a limitation of the port you are using, DisplayConfig X, or something else. The takeaway message is that you cannot magically create more pixels than the manufacturer built-in.

    I understand that it only has a set amount of pixels, but what I don't understand is why it works with the default 1920x1080 resolution (except for the overscan issue).

    it see the 1920x1080 res because that is a industry standard (I am guessing). what we are saying is that the scaling engine in your tv ( just like a scaling engine in a upconverting or other device) is scaling the picture to the native res of the pixels.

    Digital displays do not support just any random resolution you throw at them.

    No need to guess. 1920 x 1080 is the highest industry standard resolution for HDTV. NBC-HD, CBS-HD, and PBS-HD broadcast in 1920 x 1080. ABC-HD and Fox-HD broadcast using the other standard, 1280 x 720. Every 16:9 digital television set will automatically scale either 1280 x 720 or 1920 x 1080 content to fullscreen. They also have buttons on their remote control units to manually fit widescreen DVDs to your TV. Even windowboxed standard definition cable- and broadcasts can be manually zoomed to fullscreen.
