Also, it's apparently been decided that there won't be an 8k disc based media, as the data transfer rate required would be too high - if anything it might be a solid state drive of some kind, but that's unlikely too.

Couple that with the fact remastering a lot of content to 8k would be an expensive process - as a lot of films wouldn't have been shot on film that is an equivalent resolution (35mm is meant to be around 4k quality) - and that you'd need a TV over 80 inches to notice the difference over 4k, I just don't see 8k going mainstream for a couple of decades.

You need a better TV downstairs.

Just the upgrade excuse I need :datass:

I think that's an issue with your downstairs TV rather than digital video....

As costs come down they might start using it as a selling point to encourage people to upgrade even though practically it isn't making a meaningful difference. And if the TVs look better due to advancements in other areas will buy into it. It has a number on it, so it's an easy sell to say 8k is better than 4k whereas stuff like HDR etc can be more confusing.

I think they'll try, but I think it'll be the next 3D TV rather than the next 4k - manufacturers will try to push it for a couple of years, but lack of content and minimal benefits will mean little uptake and really slow it's momentum

True, but 3D TV was also held back by the need to wear glasses. You might be right though, the lack of content is definitely a big issue.

8K TVs will be the standard offering within the next 5 years, simply because that's what the manufactures will be producing - if you want a new TV, it'll be 8K. Samsung already sell their 8K TVs at comparable prices to 4K (the Samsung 8K TV was one of the biggest sellers in John Lewis last year).

Actually having something to watch on it though will be another matter. Most people with a 4K TV aren't currently watching much 4K programming outside of Netflix and Amazon Prime, and it'll be even worse with 8K. I've not seen standard definition on one but I can't imagine it looking very good.

Covid 19 buggered up the roadmap, but BT is expected to have some football matches in 8K by 2023.

I feel the main chance 8k has at content would be some future version of Nvidia's DLSS, and equivalent technology for streaming TV/films - upscaling with deep learning systems, rather than native content. But the first version of film upscaling will be as warmly received as the Hobbit was in high refresh rates, and people complained it looked like a soap opera, and it too will take time until it's a selling point.

I'm not really that on the pulse with tech these days but DLSS technology blows my mind

At least people purchasing 4K Blu Rays of old movies know they now finally have the definitive version, having probably cycled through that copy of Jurassic Park on VHS, DVD and Blu Ray.

Indiana Jones is the next one to get the 4K treatment on disc.

The majority of my viewing is now in 4k – well, not 'true' 4k, but you know what I mean – thanks to Sky Sports, Netflix, Amazon and Disney, but I hardly know anyone at all who is also in this bracket. Most people seem to still be alternating between HD via Netflix/major broadcast channels and standard definition! This undoubtedly makes me sound a right prick but I just don't know how people can enjoy SD without being totally distracted by the poor quality.

I can't see 8k being mainstream even by the end of this decade. I don't see the need for it, either, although I probably thought that about 4k a few years ago. The size of the TV required to actually perceive the benefit in a realistic setting is surely a sticking point for most people?

The 8K aspect of the next generation of TVs will be secondary to the other tech, some of which we're probably not even aware of yet. It'll be Mini-LED, 120Hz, improved HDR...stuff like that.

8K is just a natural evolution, whereas things like 3D and curved TVs was trying to reinvent the wheel. It didn't help that the tech for 3D in the home was both crap and cost prohibitive.

No its definitely quantization and DCT artefacts.

That feels like such a minor issue for the majority of content you'd watch when compared to what you gain with standard versus high definition, but each to their own!

To be fair I think our Virgin subscription is still showing a lot of SD content. I'm watching the snooker punditry now and it's clear as a bell.

One thing I'd like to see on new tv's is a system where the tv can somehow analyse the room (maybe an inbuilt camera?) and calibrate itself for the best possible picture. I'd love to have my set professionally calibrated so I know I'm making the most of it but it's an expensive service and if tv manufacturers are looking at things to whack on the box that could be a pretty big addition.

Since calibration isn't dependent on the room it should be possible to have consumer devices to help. There's already commercial devices you can get, about the size of a roll on deodorant, which you hold against the screen and helps you - and if I remember correctly Apple announced something recently to-do with Apple TV that helps with this.

Tbh my 4k TV is a bit pointless in that I watch basically nothing in 4k.

There's not much available in Poland that's at the resolution (Disney + isn't even available at all yet...). Even the rare piece of 4k content I, em, get online hasn't blown me away tbh.

Predator 4k looked great but i watched a 72gb file of Hacksaw Ridge the other day and could only really notice the res difference when looking at their hair. And it made the green screen stand out more.

If you're able to find HDR content that's meant to be a much better difference compared to the resolution jump.
