Now, I use a DVD player to output a 480p video(YPbPr) to ADV7401's CP through AIN6, AIN5 and AIN4. The original video image is:

And I let the ADV7401 to output image with '24bit @LLC1 4:4:4 SDR' format. But the output images look like this:

Display Image (T2).JPG

Display Image (T3).JPG

Display Image (T4).JPG

So, we can see that the output image has ghosting in horizontal and also the image is scrolling in vertical.

Can anyone help to tell the possible reason for this? Thanks.
