@midknight That is a really important point, midknight. It's all very well these shiny new 4k HDR sets looking so good with 4K demonstration material on USB and so forth, but since most discs in people's collections will be mainly 1080p Blu-ray, or even DVDs, the upscaling properties of any television is quite important. I have to say that eleven days ago, I was in John Lewis and the salesman played a compilation of Blu-rays, and I'm afraid that Oblivion looked no better on the Sony 65ZD9 that it does on my own Full HD televisions, so I was a bit dubious. Maybe it was the shop setting, but I'm happy to take your word that the ZD9 upscales very well.
