Hi,

Thanks for the update, I understand I can output YUV422 10 bit. My source is YUV422 8 bit and I want to render it to HDIM as YUV422 8 bit not 10 bit, the reason I’m asking is because the TRM it states (see below) the HDMI interface supports this mode.

7.6.2.3 HDMI

YUV444/YUV422 output (BT.601 and BT.709 formats)
8/12 bpc RGB444/YUV444
8/10/12 bpc RGB422/YUV422
8 bpc YUV420

I can the set DRM_FORMAT_YUV422 or DRM_FORMAT_UYVY for NVBuffer however I see the HDMI output is still RGB instead of YUV422, My monitor supports both RGB444 and YUV422 8bit and I want the hdmi output to be YUV422 8 bit not 10 bit.
