    Full RGB mode has wrong levels


    I recently discovered that the Xbox's Full RGB mode has the wrong levels set. So no matter what cable you use it's wrong. It appears to be a firmware issue.

    Display Calibration and RGB, black levels

    As of the most recent Xbox 360 and Xbox One updates, the problem is still not fixed.

    I have my TV calibrated and configured properly. I have tested it with my both my PS3 and PC set to RGB Full and RGB Limited, and my Wii U (which outputs RGB Limited)

    It works perfectly with all 3 devices.

    On both the Xbox 360 and Xbox One, however, the output from the both the RGB Full and RGB limited options have 16 levels of black crushing and 16 levels of white crushing when the TV is set to the corresponding mode, and only look normal when the TV is set
    to RGB Full, and the Xbox is set to RGB Limited.

    I don't have recording equipment, but others have recorded output and tested the black levels in photoshop to verify this issue.

    Essentially the problem breaks down as follows:

    Black Levels

    15-239

    - PS RGB Limited option, Wii U, PC RGB Limited output

    0-255

    - Xbox RGB Limited option, PS RGB Full option, PC RGB Full output

    (-16)-271 (values out of range by 16 levels)

    - Incorrect Xbox RGB Full option

    Reference Levels and HDMI Color Space Settings

    Expanded is full RGB, The system video player and picture viewer have the levels switched the wrong way round, It works properly for games though.

    So, if my TV is Full HD i have to set my Xbox's resolution to 1080p? and use the LG's PC Mode, Black Level High, 1.9 gamma? are those the optimal settings? (Expanded Reference Level, RGB)

    Your best bet for using RGB expanded is turn off display discovery, Set the xbox to expanded RGB and TV to PC mode if possible, Although PC mode on my Samsung looks awful without a lot of sharpening so i just use movie mode and set the black level to normal.
    If you can calibrate your display first with a pc or some other source it would be better as the xbox system video player does not seem to output Full or Limited RGB properly, but Netflix seems to output as it should.
