On our board we have two ADV7619. The first one is very close from HDMI connector and the second one is at 15 cm from connector (due to mechanical constraints).
We are compliant with equalizer settings "ADV7619 Required Settings Manual" rev 1.8 and it works correctly for both ADV7619 except when cable length is important.
With a source in 1080p@50 (RGB 4:4:4 24 bits, no HDCP) connected with a cable of 10 meters it works great with the first input but some pixel artifact appears on the second input especially on dark content.
As equalizer registers are not described we cannot tune parameters to adapt them to our specific constraint. Can someone helps us on that case ?
Thank you in advance.
