ADDI7004  does not move the video stream to the dark

Hello ,

with the function black clamp I have a problem. I would expect that the ADDI7004 is changing the video stream to more dark after writing to Register 0x10 to 0x13. I of course use the CDS Mode and the register 0x02 is set to 0x01.

But it does not work. The video stream stays at the same bright level. I expected tthe video stream to moved to the further dark.

What is wrong?
