How do you optimize non HDR content in 1080p vs 4k streaming video? You just have to calibrate to that type of source material and save it to a specific settings profile. Switch to that when it's the content you're observing. However there's no point to optimizing a 1080P setting on your 4K tv so don't bother with it, I'm just pointing out that if all things were equal on a 1080P display vs. a 4k display, and it's not HDR, the image quality difference is very small. 8K difference to 4k will be even smaller. HDR is what really makes 4k shine, and should be leveraged to the max if possible. Currently there is no similar game-changer tech in 8k, just more pixels. Until there's some HDR type game-changer, there's no point in going 8k, *especially* if there's no true 8k source material. That's Dan's point. Yeah I hear ya. But, I heard this same thing about 4k... now everything is 4k and 1080p equipment's value drops like a stone. |

I've never sold a tv. I'll just repurpose it to another room when I get a bigger one. I'm only aware of like one 8k OLED and it's ridiculously expensive right now so it's not on my radar. |

Until there's some HDR type game-changer, there's no point in going 8k, *especially* if there's no true 8k source material. That's Dan's point. So true ; swapping from a shrunken rec709 colour gamut to a dcip3 hdr pallet you see what more accurate and extra colour shades does . hitting that with higher dynamic range so the sun for example looks more like real life [ie brighter] is the game changer and we allready have that with hdmi2.0  no coincidence that a file with btr2020 hdr10 rather than rec709 is much bigger to handle the bandwidth it streams . And this bandwidth only goes higher comparing streamed dd+ to a better 4k hdr stream from a 4k disc .. the uncompressed uhd disc is better than compressed 4k from an app  why not help it and feed it directly to the tv not through an avr's circuitry? We have seen how much futzing around D and M had getting just 1 2.1 input to work [as well as cumbersome switch box dongles] why not send a clean ps5 or xbox signal with vrr allm etc direct to the tv and use E-ARC .. I think its a good idea to recall the problems Emo has had with hdmi iterations ; e-arc simplifies things and saves the price of a new hdmi 2.1 board .. |

I'm only aware of like one 8k OLED and it's ridiculously expensive right now so it's not on my radar. Down here the sweet point for large tvs that do justice to 4k uhd signals is 85" really appreciate the extra size from my old 65" ex780 sony . Its when you go to 100"that the cost starts to balloon A good FALD screen can come pretty close to an oled if it has enough dimming zones ; and they usually have more nits which helps daytime viewing [as well as better hdr dynamic range] . The latest exxy oleds are still trying to match leds nit levels [slowly getting better]. Good idea to check out a few mini leds as well ; cheaper than oled I put my old sharp 40" on a wall bracket and feed it 1000's of youtube mp4 videos through an old pvr ;great when ensconced in a massage chair being pummeled  |

I guess it’s the same as 65Z9D in the US. It has got 640 zones which makes it have really good blacks when needed. The follow-up models have not had as many zones due to cost and Sony have had to make improvements elsewhere to match or better this model. As a whole it took them 3-4 years to beat it with a truly better performance. This TV has +1800nits output calibrated. Because of the many dimming zones very good blacks also. However technology has gone past this model in some other parts. Like its very noticable clouding, motion handling with the newer chips and better color settings for an even more correct calibrated picture. Then they also have better panels these days. This model is after all from 2016. |

what are we talking in terms of 4k are we speaking terms of its original dvd standards 100mbps-1gbps standard or are speaking minimum standards of 2.5gbps through 8.5-10gbps standard of blue ray or beyond..
Pixelation of an image typically happens when you upscale a stock image from 720x576 to 2080x1080 then the same image to 4k dvd vs 4k blue ray with no proper transcoding of the content
Garbulky just proved this point noting the bigger the image the more bandwidth it takes to view it even with a 1080p presentation is going to cause issues when it is upscaled to a resolution it can't natively handled..
as for 8k and 4k in terms of tv support at 65" you aren't going to notice much difference between 4k and 8k, you will likely notice a difference from 75-82" anything above that is likely a projection job
some how i don't think anyone in ht circles 65'(height)x45'(wide)x 85'(length) 35-60 row fitted with 1 ohm capable speakers and thx cert amps to boot..

why not help it and feed it directly to the tv not through an avr's circuitry?
