New Release - Firmware Version 3.00.28 for WD TV Live Hub (11/17/11)

Upgraded from previous version and found that in Set up Audio Video outputs the window with the deep colour 12 bit adjustment disappeared. Now I don’t know which colour is used by WD, 8 bit or 12 bit. I always used 12 bit before. How to fix it ?  

It’s using 8-bit.    12 bit is no longer supported for resolutons higher than 720p.
