What are the case usage for selecting HDMI Video Range setting of "Full" or "Limited"?
I'm sending 4K HDR10 Blu Ray content from the Panasonic UB820 in Full, and the blacks are lifted, gain is increased, everything appears washed out. When I select Limited, the blacks are deeper, colors more saturated. Obviously, I prefer Limited because the HDR simply pops out of the screen but now I'm wondering why the "Full" video range is supposed to be better (more colors, more accuracy?) if it ends up reducing the punch of HDR - Any opinions?
Sony's website explains it thus
"The HDMI® Dynamic Range feature helps produce natural color by changing the luminance tone reproduction of HDMI input color signals. The dynamic range of the image is reproduced properly by selecting the desired dynamic range for signal type being used.
* Use the Auto setting during normal operation. The Auto setting automatically selects the dynamic range Full or Limited based on dynamic range information coming from connected device.
* The Full setting should be used when you would like the signal range fixed to full range. An example may be a high-definition signal from a device connected using an HDMI cable.
* Limited: The signal range is fixed to limited range. This should be used when less color is desired.
There is small possibility that the connected HDMI device will send wrong dynamic range information. In this case, if Auto is selected the TV will default to a limited dynamic range and the picture may appear with either white saturation (no details in bright white areas) or black saturation (no detail in dark scenes)."
: actually, I realized that maybe it's my bad for enabling the Panasonic's HDR Optimizer, this may result in over processing of the image so let me run some A/B testing with and without the Optimizer on Full/Limited and I'll let you guys know.
