For the 4+3 gamma the target value is 2.2 and error range is
±
0.05.
Note
④:
We will add more project ID later.
Note : If we can do both of White Balance & Automatic Gamma correction. For some special models, please notice
the information provided by Huizhou factory or PJM to choose which way to make it.

Cloning
Once a TV is well aligned and prepared (channels maps, volume, picture presets, …) , user can prepare golden
