New 4k Freesat box (1TB) - strange phenomenon with picture quality

[BuffetSlayer]

Hi all

So I have just cancelled my Sky TV packages and bought a freesat 4k box.

I have a wide band LNB and have great signal strength/quality to the new freesat box.

I’m running the box through a 55” LG C2 OLED.

I’ve set the box to 4k picture output but the picture quality is dreadful. On HD channels like BBC the picture is not anywhere near as good as it was on Sky Q. It isn’t just the channels though, the user menus are also in a terrible low resolution which seems really strange.

Strangely, when I set the box to 1080p, everything sharpens up and both menus and channel picture quality are loads better.

I’m reallly confused! (Doesn’t take a lot )

Does anyone have any experience of this and know how I can get a good quality picture on 4k output on a 4k TV?

I think the first 2 obvious questions have to be, are you 100% sure you are using a 4K HDMI lead and is the HDMI port you are using on your C2 set to 4K Deep Colour ?

Yes to both and in the case of HDMI Deep Colour - it’s one of the things that was causing the problem.

I disabled it and changed a few other settings to compensate and things are now much better.

I’m still tinkering but I read somewhere that Deep Colour should only be on for HDR content. I’m not an expert by any stretch, but disabling it seems to have done the trick.
