DS90UB940-Q1: How to inhibit invalid long packet on the input video format switch

Part Number: DS90UB940-Q1

Hi Team,

Please advise me on the following questions.

I am using DS90UB925 and DS90UB940 as a set.
On the DS90UB925 input, two different video formats are dynamically switched vice versa.

When video format was switched from 1280x720 to 1920x1080, DS90UB940 outputs two
1280 long packets on the top of 1920 line.


1280x720 1920x180

1280 Pkt 1280pkt 1280pkt+1280pkt 1920pkt


Q1. Is it designed behavior?

Q2 Are there any way to inhibit DS90UB940 output such gavage long packet at the instance of switch input video format?
