Acquire from PS4 PRO in 4k with Mini Recorder 4K

Hi to Everyone,
i would like to capture video in 4k from my ps4 pro with a Mini Recorder 4K directly.

When attach the PS4 Pro to my Mini Recorder 4K, i can not send the signal from the PS4 Pro dashboard in 4K...the resolution is missing(2160p), the maximum is 1080p.

does anyone know how to solve this problem? I have disabled HDR and Deep Color, and move HDCP to 1.4, without result.

Do i need a TV with a HDMI splitter for capture from PS4 Pro in 4K and my Mini Recorder 4K ?

Thanks to all.
Regards

Anyone could me help about this issue ?

Mini recorder will only capture up to 2160P30.. Your PS4 will do 50 or 60?!
So you need to put down the framerate if you want to go 4K. Or buy a Decklink 4K Extreme ($895) to get 2160P60

PS4 won't do 2160p30.
