Now I plugs adv7511 to DM368's digital video interface(YCbCr 4:2:2), and outputs a 720P 60HZ video. The dm368's decoder shows video is decoded in 22 frame rate by 720P format, and the oscilloscope shows Y signal, TMDS' data0 and clk singal output normally, but the monitor with dvi does not display image. The adv7511's register values are shown bellow! What is the problem? Thank you!
