Raised black levels?? hdr rgb mode

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

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)

This was an issue on the Xbox 360 and it was never fixed, so don't hold your breath.

The issue is that the Xbox seems to output 0-255 black levels when set to RGB limited, causing the black and white levels to be crushed, even when the tv is set to RGB limited.

And then when setting it to RGB Full, it seems to output even lower black levels and higher white levels, such that the black and white levels are still crushed when the TV is set to RGB Full, and even MORE crushed when set to RGB limited

Setting the Xbox to RGB Limited and the TV to RGB Full seems to make the blacks and whites look normal, but intermediate shades (and colors) are washed out.

The only workaround I've been able to find is to set the Xbox One's "TV Connection" setting to "DVI", which seems to fix the RGB limited and RGB full settings to their proper black levels, but you no longer have sound over HDMI.

The best way I've found to test the black levels on the XB1 is to save a copy of the Lagom LCD black levels test image:

and these grayscale gradient test images:

to SkyDrive, and view them on the console each time I change a setting.

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.

[/quote] Yes. That is correct.
