Recently I made a project ------ 4 1080 p (1920x1080) to synthesize a 4 K (3840x2160,297 M) interface board. When 1080 p goes in and p goes out, the video is played normally. However, when P and 4 K are in progress, the video image will have water ripple. At that time, it was assumed that the timing sequence sent by FPGA to the downstream device SII9136 could no
