That reddit thread reinforces the X900H status as likely to be the PS5 Partner display (4K/120 being an important factor)

AIUI the X900H may be better specified in this regard than the more expensive X950H?

Yes, hardware wise it's better, latency wise it's better, but I'm not sure about the postprocessing capabilities of MediaTek chips vs the Sony X1 Ultimate.

I switch off all the post-processing options in general so that may not be a huge issue for me personally.  First thing I do usually is disable or switch off Reality Creation, MotionFlow, Smooth Graduation, Noise Reduction, Live Colour, Contrast Enhancement etc., and I set sharpness to do nothing.  I want to see as clean and neutral a picture displayed as I can, so it is as close as possible to the picture seen in an edit suite or a control room. (I work in Broadcast TV and none of our broadcast monitors have any of that processing stuff - just decent calibration options).

I don't know all the post-processing involved in Broadcast TV, but there's one thing that's really bothering me and it's dependent on various implementations: deinterlacing of HDTV 1080i content. The MediaTek one can't be that bad versus the Sony one.
