ADV7441A Problem with large vertical blank interval in DVI Mode

Hi all,


we have a problem with a custom resolution with a vertical blank interval bigger than 255 lines in DVI Mode. It appears that the output DE signal from the ADV741A is stucking low and the HS interval is varying between two values. The HDMI synchronization registers in the HDMI Map show the expected values for the resolution. How can we solve this issue?
