Samsung Qled 90t 4k 120hz VRR (Game mode) problems

When using my Nvidia rtx 3090 with my Qled 90t on 4k 120hz VRR (Game mode) Sometimes it just works. And everything is how it suppose to. But other times. I get all sort of problems. I get blackouts and strange lines on top of the tv. And tv menu starts to lag like crazy. Sometimes it starts out fine. and after a hour the same thing happends. The whole tv starts to freak out and the tv starts lagging like crazy I get flickers and blackouts. I tried different Certified HDMI 2.1 Cables (all this cables have no problems on my LG Oled CX up stairs) And the same thing happends. Is it possible that my Q90t has a defect that needs to be fixed ? Because this is getting really annoying.
