Display problem with new TV

[Tangfolio]

Just got an OLED TV and getting a strange 'shimmering' effect on some stuff from the Vu+ Solo 4K box.
I have tried the box on all HDMI sockets and sometimes it is OK for a while but then it comes back.
Don't have access to terrestrial to try the aerial input on the TV, live in Bilsdale area, but have tried a Fire TV box and no sign of the effect from that in all HDMI sockets, also tried various on-demand services installed on the TV and they all seem OK and no sign of it on videos played from USB sockets.
Also tried a clean install of Openvix 5 4 014 but no difference.

Attached a couple of pics, problem circled in red. Circle is not too clear on history zap pic but it is right across the top.

So wondered if anyone might know what is going on.

What are your AV settings on the Vu?

Better quality HDMI lead required for a higher tv resolution you are now unsing on your new TV?

Do you get the problem when you set your box to 1080i?

HDMI leads come in different specifications and if you are attempting 4K resolution you may need a more recent spec cable.

Got it sorted, been experimenting with AV settings and the box was on 'multi' frequency and putting it on 50 appears to fix it, 60 produces same problem, seems a bit odd as blurb for the TV says it works up to 120.
We had already got HDMI 2.1 cables.
