PSR2 vsc revision number hb2( as per table 6-11)is updated to 4 or 5 based on Y cordinate and Colorimetry Format as below 04h = 3D stereo + PSR/PSR2 + Y-coordinate. 05h = -3D stereo- + PSR/PSR2 + Y-coordinate + Pixel Encoding/Colorimetry Format indication. A DP Source device is allowed to indicate the pixel encoding/colorimetry format to the DP Sink device with VSC SDP only when the DP Sink device supports it ( i.e.,VSC_SDP_EXTENSION_FOR_COLORIMETRY_SUPPORTED bit in the DPRX_FEATURE_ENUMERATION_LIST register (DPCD Address 02210h, bit 3; is set to 1).
