ADV7619 acts as a RX,it's output send to Xilinx FPGA,when video source resolution is 4Kx2K,FPGA DVI output will flicker randomly,when lower the resolution,flicker disappears,and when reset all these chips,these little screens will not flicker,but the other two or three little screens will flicker.the question is if adv7619 registers configuration cause the problem,how to solve it?
