Wonder if any of you experiment with this register and get the same result as mine?
Refer to ADV7441A_HW_revJ section 3.5.1 page 41.
If I understand the document correctly, when register 0x6A[bit5] = 1 the DLL is bypassed and we don't care the 5 LSB [4:0]
Matter of fact, we experience strange behaves. Setting register 0x6A to 0x30 make the image more stable than setting it to 0x20
