We found flickers on the display connected with our ADV7623 board about one time per 10 hours.
Also we found HFG setting had an effect to improve it.
Q1) Is the value described in ADV7623_RecSet_Rev1.2_031011.pdf only reference and we need to adjust it for our system?
Q2) Does not only HFG but also LFG need to be adjusted?
Q3) Is there any range to set it?
Q4) Is it possible to show us the equivalent circuit of the equalizer?
