Delayed Start of Movie

I am using ZMDC with the Nuplayer of the Z9S. When starting a movie there is a 5..8 sec delay while switching to the display resolution (2160p) of my sony 75XD9405 and the 5..8 sec at the beginning are not displayed although the sound is audible. The same is true when using the Z9S Mediacenter. A reasonable way should be that the movie only starts after the resolution has been switched. How can I correct this??

 

I think you can configure a delay using a setting when switching just for that purpose.

 

Thank you for the hint! I had set that in ZMDC but should have done it in Z9S setup! Now it works.
