ADV7611BSWZ-P and ADV7511KSTZ-P issue with Live feed

Hello folks,

We are trying to build demo application for HDMI input and output. For this we are using Picozed board with FMC daughter card. The FMC daughter card has ADV7611BSWZ-P As HDMI In and ADV7511KSTZ-P as HDMI Out.

On HDMI In side we are giving Live feed i.e TV set Top box and applying HDMI Out to TV screen.

While testing we are not able to see full screen output, it shrink to half screen output as shown in below image.

we are not able to find out the exact problem. Is it because of the  -P version of IC which is  non HDCP ( ADV7611BSWZ-P, ADV7511KSTZ-P) ?

If yes why it is showing half screen not whole black screen?
