hi, buddy

     I have a problem. My system consist of a 7441a and a 9889b  and the input is DVI signal which goes through 7441a and 9889b then output DVI signal. But on the display the image is not clear, and has some beating lines and the color is fuzzy.

     I use script  ADV7441A_ADV7441A@_ADV7441AVDP_ADV7441AHDMI_ADV7341-VER.MB2.0.TXT, as below:
