Really bad contrast issues. HELP!

Hi all,
Really struggling here. Have a Philips Ambilight TV (55PUS7334/12) and we’re running Apple TV through it. But all content seems to come through with the dark areas REALLY blocky. I don’t know how to explain but see pics. We’ve tried swapping cables, ports and even swapped the TV, but always seem to have the issue. My gut feeling is it’s a setting issue between the Apple TV unit and the TV itself. But I. Buggered if I can find the right settings. Any help?

Plenty of threads on this if you have a look, I'm not sure if anyone managed to sort it out but it seems to be affecting all lcd models across the board, I ended up selling mine and getting an oled instead, it drove me potty.

Hi, under the video settings on your apple tv change it to 4k sdr 50hz and change colour format to ycbrcr ,
I think the problem is that the Viking series is not a hdr series and the apple tv is outputting it out as hdr or dolby vision which I'm assuming is your current setting and the tv is struggling to render it properly.
Don't worry about the sdr setting as your apple tv will output any hdr signal as hdr or dolby vision.
Hope this helps.
