      Switching to UHD

      Most times (not every) when I switch to UHD i have to go and re-set up.

      I have LG UHD TV and sky usually selects 10 bit if I auto-select, I have tried both that and 8 bit with no difference.

      I am probably missing something but not sure what?

      Help appreciated.

      Cheers

      Alan

      Re: Switching to UHD

      My first question is why are you switching if you have an UHD television as that would be the optimal way to watch.
      We have our LG OLED permanently outputting to 10 bit even when we are watching normal SD or HD channels.
      The ability to see a difference depends how far you are away from the TV when you watch.
      This has been widely discussed on the internet and there are many articles about this.
      We find that when we are watching an UHD programme the colours and brightness are enhanced over a HD programme and vastly superior than SD.

      Re: Switching to UHD

      The problem with Sky Q is that it has a rubbish scaler. It's basically a pixel doubler [quadrupler(?)] rather than a interpolating scaler and does virtually no post processing to remove deinterlacing artifacts. I find with the box upscaling HD produces a softer looking picture than when the TV is upscaling. The scaler built in to LG sets is significantly more advanced and does a far better job.

      If you have a newer LG OLED set (2017- ) it will have Active HDR which simulates HDR on SD pictures which would explain the difference you are seeing. On my calibrated 2016 set there is very little difference in the colour and brightness on HD and UHD programmes which is as I would expect.
