Is it really worth buying a UHD OLED TV?

Recommended Posts

Hey there.

I know we UHD OLED Tv', such as 4K and the resent release of 8K tv are available to purchase.  I understand that we currently don't have any TV programs that is in 4K. I usually watch Netflix and there are some programs in high resolution but most are not.   So what gives, is it really worth buying such TV if you are only watching TV an pay-tv in Australia?    Can any audio guru enlighten us in this topic please?

Netflix, amazon prime and stan all have a significant amount of content available in 4k now.  If any of it is of interest to you and you have NBN then it is probably worth purchasing a 4K TV.

4k yes with some caveats....

 

yes we have the media.... in both disc and streaming. will need a telly large enough to resolve the higher resolution or sit very close.... there will be some benefits regardless in colour volume and dynamics to the picture due to HDR and WCG. 

 

8k ? no... no media and completely non sensical in the home...

Hey Lil Caesar.

I did purchase a 75 incher for my home theater.  I do use it for Netflix and Its probably the only option I currently have that makes it worthwhile to use my TV.  Thanks for the update mate.  Just wondering what our TV channels use, not 4k I guess, would it be 2K?

Thank you Betty Boop, its reassuring to know that information.  Just out of curiosity, what does our TV channels broadcast on??

your not going to be looking for any benefit with 4k and our TV channels they are barely 1080i at best, many are 720p and really not even that since heavily compressed in both picture and audio....

Great to know, I will keep watching Netflix with the 4K rating to get the most out of my HD system.

Thanks again Betty Boop!

4K is just a marketing number, especially with streaming. None of those services can deliver even close to 4K actual resolution and the per pixel "quality" is lower than 1080 Bluray disk because the data rate is now where near high enough.

4K Bluray disks support over 100Mbps for a reason, streaming services offer only  a quarter of that so resolution and picture quality suffers.

 

1080 streaming is crippled by insufficient data rate as well, both resolution and quality are no where near 1080 Bluray disk.

 

So, if you want to take full advantage of any display forget streaming.

 

Free to air TV is also VERY heavily compressed which guarantees resolution and quality are no where near what the pixel format would suggest. High data rate rules.

Once you go 4K OLED, there’s no going back.

That depends on what you view and where you view it. Unless dark room viewing is of prime importance OLED doesn't make sense IMHO.

 

I see no point in 4K with TV size displays, even with big screen projection systems 4K is of marginal benefit.

Apart from UHD BD & Current/Next Gen Gaming consoles,  does Foxtel’s 4K service justify having a 4K TV?

 

I’ll end up utilising all 3 of the above, hence why I’m aiming to jump on 4K this year.

I have recently got a 4K tv and have Foxtel, I recorded the F1 on Foxtel in HD and 4K, there is no comparison, chalk and cheese, 4K has much more detail and is clearly better.

No doubt it would be better, comparing the HD channel at about 8-9Mbps to the 4K channels 25, isn't really a fair 1080/4K comparison.

That’s a fair point. 

 

Foxtel HD has gone downhill since its inception, so we can’t know for sure what the difference between its HD & 4K channels are, unless they boost the bandwidth for HD.

 

They’re effectively selling 4K behind a smokescreen that masks their own tampering...

Bingo. High data rate rules so 1080 Bluray with up to 40Mbps blows Foxtel and Netflix into the weeds.

I just can't view either on a big projection screen, the video and sound quality is just unacceptable.

Thats because 1080 Foxtel is utter, utter CRAP. Your Comparison is therefor pointless.

 

You don't need a 4K TV to view so called "4K" Foxtel or Netflix. A HD Fury device will allow you to display so called "4K" content on any TV to take advantage of the higher data rate. You sure don't need a 4K TV as the content has at best 2K resolution, and thats being kind.

I have evaluated OLED TV's and thats why I DON'T own one and wont until OLED's inherent limitations are addressed.

For "quality" viewing, such as Bluray movies, OLED doesn't cut it, nor does ANY TV, The picture is WAY to small and TV's look too digital for my liking. Its JVC projector or nothing.

For general TV and other low quality source viewing OLED performs poorly, so no go there either.

If you view in a bright room LCD does a better job, and if you view in the dark OLED's poor dark screen uniformity and second rate colour resolution are unacceptable to me. I wouldn't put up with that level of performance 15 years ago so why would I do so now?

 

My toy budget is $30K to $50K per year so purchasing an OLED TV is a non issue, but no way I will buy one until they do what I need better than what I have.

Impressive annual toy budget you have there Owen, Given your expertise with projectors and TV I’m sure I’m not the only one who would be interested to hear what your HT set up is like and what upgrades you have invested in recently.

 

cheers Terry

I have a 58" 1080p Panasonic plasma from about 10 years ago.

 

So I'm expecting that picture to be improved upon with a 2019 65" 4k OLED, for my needs (BD, UHD BD, PS4 gaming).

 

(No SD content since the Foxtel box was swapped for an IQ4).

Hi

 

IMHO no.

 

4k content is still limited, although some of what is transmitted via streaming I find nice to watch.

 

But for me the main reason is you will mostly be watching up-sampled material.   The very best up-samplers are not on 4K TV's but the new 8K models.   I have just got one and it blew my 4K TV out of the water - clarity and depth on HD that everyone notices being better than even 4K material.   Why is that?   See the following:

http://www.insightmedia.info/8k-tvs-top-tv-line-ups-for-a-reason/

 

I can confirm from owning one myself it pretty much what I personally notice:

'As a result of the study, 8K displays performance was rated 35% higher—with perceived image quality increasing by 30% and depth perception increasing 60% from 4K to 8K.'

 

They viewed at 9 feet - I view at about 10-12 feet.

 

Its at a good price right now:

https://www.harveynorman.com.au/samsung-65-inch-q900-8k pro-qled-smart-tv.html

 

If its in your price range I would seriously consider it.

 

Be aware however that exactly how 8k will be transmitted or even if it will look any better than 4k up-scaled via the new Artificial Intelligence Algorithms these TV's have is not known at this stage - nor is there any 8k material being transmitted.  But, as I said, to me up-scaled to 8K, HD looks better than 4k did on my old 4k TV.  My guess for what its worth is they will transmit 8K at lower quality level than 4k and rely on various tricks (eg using AI like used in up-scaling) to make the quality better.   Foxtel is already doing it in their 4K - they use an algorithm by a company called Harmonic to transmit parts at lower quality that you will not notice:

I don't find that to seemingly be the case at all. I find that most 4K material is not up-sampled.

I cant comment on the high end stuff, but last year I bought a Hisense 50P7 and have been very happy with it considering its price ($795) based limitations. I watched this youtube video last night and was gobsmacked at the picture quality. I didn't realise initially that it was "4K", but I think it shows what can happen with great production and UHD. Would be interested to hear the opinions of the video from OLED users.

That's not what I meant.   A number of streaming services have genuine 4k material and its increasing.  Some of it I even like eg Warrior.  What I have noticed is on my 8k TV its up-sampling is much more sophisticated than on 4K TV's, being based on AI, so that its more like 8k restoration than up-sampling.  Its so good I prefer it to actual 4k material on my old TV.   I forgot to mention for me the situation is not quite as good with SD material.   Just watching The Good the Bad and the Ugly transmitted in SD and while good I would say its not as good if it was HD ie the up-sampling is not as effective.   But there is still a lot of HD material about to make it worthwhile.

 

The only issue is expense - nearly $6k for a TV is a lot - but like 4k TV's prices will soon drop.  However if you are able to spend that sort of dosh it is worth it.   My Femur broke and it will take about another year to fully recover, although I can get around a bit now and go to lunch each day etc, I had to get a friend to do the following comparison.   It was at Harvey Norman and they got a Sony 4k OLED and the Samsung 8K next to each other for a comparison on 4k material.   Up close you could still see pixels on the Sony - but try as you might there was none on the 8k,   From a normal viewing distance the blacks and etc were clearly better on the Sony due to the OLED - it would be great in a darkened room.   However he preferred the Samsung 8k - the picture, while not as striking as the OLED was more natural, clearer, and with greater depth.  Why that is, is explained in the link I gave before.   At 8 feet picture quality on the 8k was rated as 30% better and depth 60% better.   Combine this with state of the art up-sampling and for me it was the better choice which is why I got it.   Now I have it I just love it - best picture I ever experienced.

 

The caveats are of course expense and no actual 8k material.   They haven't even figured out a standard way to stream 8k or even at normal viewing distances if it will look better than up-scaled 4k.   This is cutting edge stuff with a lot of unknowns.   The only thing I can say for sure is the Samsung 8k sure has a great HD and 4K picture.   The SD picture, while good is not quite in the same class.

 

Thanks

Bill

No streaming service has "genuine" 4K material. Streaming required WAY, WAY too much compression.

4K Bluray disk with a peak data rate exceeding 100Mbps is the only domestic source of "genuine" 4K movies, and all 4K video formats (before compression) are limited to about 3K luma resolution and only 1.5K chroma resolution best case because ALL video is 4:2:0 colour sub sampled and deliberately low pass filtered to avoid aliasing. Most movies are well below that no matter what camera they where shot with or how they where mastered.

 

Don't be sucked in by 8K hype and marketing BS. The reasons why you prefer your new TV have nothing to do with more pixels, you just attribute what you see to that because marketing put the idea into your head.

Rubbish, beyond the distance where the indiviual viewer can no longer resolve a particular resolution, say 4K, adding more pixels does nothing useful.

Image depth is dictated by contrast and gamma, neither of which is altered by more pixels than you can see.

 

I've done plenty of testing to investigate this topic over the years using 8K DSLR images so I speak from first hand experience. I don't just rehash what I read on the inter web.

The notion that 8K is 30% "better" and has 60% greater depth on a 65" TV at 8 feet is utter nonsense.

 

As for "upscaling", you do realise it doesn't add any resolution or detail don't you, it just adds pixels. The result is a slightly smoother - softer look IF you are viewing from a distance close enough to see it. If the upscaled image looks sharper or clearer its because its been digitally sharpened, and or image gamma has been tweaked, plain and simple. Up scaling on its own doesn't do that.

Manufacturers have been using digital sharpening to suck consumers into paying for more pixels for years. Its easy to hoodwink people when there is an expectation that more pixels must mean better.

Unfortunately the quality of the pixels cannot be expressed on a spec sheet and that matters more the quantity.

 

Comparing TV's that are not calibrated to exactly the same standard tells you nothing unfortunately.  After calibration almost all of the differences between sets evaporate.
