Samsung RU7400 4k - how do I get 4k?!

[anonymous-user]

Hi
I purchased a ‘43" RU7400 Dynamic Crystal Colour HDR Smart 4K TV’
Says 4k on the box etc etc
I have SkyQ
I go to SkyQ menu, Audio Visual, choose 2160p. Doesn’t work 10bit or 8bit
Nothing useful found yet via the Samsung menu to make it UHD
I have the UHD Sky cable with the pink connector into main SkyQ box
Any ideas please?
Is the TV really 4k from eg SkyQ?
I can return it (25% off from Samsung direct)

Working now - user mis operation...
When I selected 4k on SkyQ it tries eg 10-bit, but is just a blue screen with sound. If I confirm that’s ok...the picture comes up, maybe that’s normal?!
Anyway 4k content is 4k now..

Good stuff

I found the 10-bit test to be a bit dodgy on Sky Q. Wouldn't work if connected through my AV amp. Connected directly, test passed and 10-bit selected, re-cabled through the amp and 10-bit still working as it should because everything is compatible.
