Hi,
It may be synchronization or timing issue.
1. Monitor the vsync, hsync & blank period.
2. Give different values on the 0,0 pixel and see whether you are facing the same issue.

Than you Anand Raj Shankar for your answer,
I will check the h_sync, v_sync and blank signals as soo as I can go to the lab.
Meanwhile I can tell you that I set the Clocked Video Output module like this:

I wish to use a 640x480(60 Hz) format. Is there anythik wrond with it?
Best regards, Dario B.
