Hisense picture issue

[judette]

Hi, I've recently purchased a new Hisense Uled 65U8KQTUK TV, 2023 model ans I'm having really bad picture issues with my sky q box. I'm pretty confident sky q is the cause because it never seems to do it using the built in apps. Regularly the screen will go really weird and stutter a lot. It doesn't need to be fast moving motion.  Even very slow scenes will do it. Im unsure if it's just a simple issue with my settings. I'm plugged in to the 60hz HDMI plug on the TV using a good quality 8k hdmi cable. The Sky Q settings are on 2160p 10 bit. I've added a screenshot of the issue

Looks like poor satellite reception.

Do downloads work?

Hi, no. Some downloads are much worse. I've been watching live snooker tonight and it's done it about 4 or 5 times. Ive also downloaded a series that we've been watching, and it does it every few minutes or so. I've reset all the picture settings to factory and its not helped. It's starting to get really frustrating.  

If I watch Prime or Netflix through Sky, it's totally fine.

So a little more information. 

I can watch netflix, prime or any other app through sky q and the picture is always perfect. I can watch apps directly through my tv and again, the picture is always perfect. 

The issue is only present when watching live TV or downloads with sky q. So it makes sense it's a sky q issue, not a tv issue. 

Anyone any ideas??
