Color Space Conversion Setting
INFO:
INFO: DisplayPort signals over 18Gbps will be converted down by either truncating bit depth or
by converting RGB signal to YUV 4:2:2 12-bit signal based on user selection. The second option will not
reduce the color depth rather, it results in loss of chroma information.
