CEA-861 says: "A Source shall not send a non-zero Q value that does not correspond to the default RGB Quantization Range for the transmitted Picture unless the Sink indicates support for the Q bit in a Video Capabilities Data Block." Make TDA998x compliant by using the helper to set the quantisation range in the infoframe, and using the TDA998x's colour scaling to appropriately adjust the RGB values sent to the monitor. This ensures that monitors that do not support the Q bit are sent RGB values that are within the expected range. Monitors with support for the Q bit will be sent full-range RGB.
