Monitor Preview Jittering

Hi there,
I have a BM Declink mini 4K and use a Sony Trimaster OLED via SDI and a LG CX OLED via HDMI.
On both devices I have some kind of jittering when it comes to large movements in the picture. I don“t have this on my GUI Monitor.
Does anyone know where this coms from? Maybe I got some wrong settings in DaVinci...?
Thx,
Tobias
