I've read about some people taking USB sticks with content on it to see what the tv they're interested in looks in stores. How do they get the content on there and this there some website to download 4k samples?
Google, Demo UHD 3D

Yes I would recommend the Life of Pi demo. Sony HDR Camp is another good one.

You'll need to check if your tv can play the different file types.

Haven't got it yet. Was gonna go down to currys to see if the one i want which is the LG E6 oled is in. Plug in the USB and play some of the demos. Apparently though i have to first convert them into mkv files then in the store take tv out of store mode and turn tru motion off.

The usual store environment isn't the best place to evaluate picture quality due to lighting and viewing distances. e.g. Bright lights would tend to favour LCD screens.

Unless they are a specialist shop and have a demo room setup where you can view in conditions closer to what you have at home.

Don't know if they do have a demo room. They should do especially when you're paying these prices. They're opening again tomorrow after the store had been renovated.

What does the price of the set have to do with it?, there's little profit in it for the retailer, the sets are expensive because they are expensive to manufacture (and to try and recover some of the development costs).

I was thinking more about the buyer.

Doubt you'll get demo room facilities with high street stores like Curry's or PC World. You're better off going to an independent retail like Sevenoaks or even Richer Sounds, somewhere that has a dedicated room that is akin to a home environment.

Unfortunately neither of them are close to me especially sevenoaks.

LG and OLED have it in my book.

For years I've put up with blacks that are actually gray, especially in dark scenes. I've swapped to a 4K OLED with HDR TV after 10 years service of my faithful Sony LCD TV and the difference is remarkable. And I haven't even managed to hook up a 4K source yet. UHD 4K blu ray player next.

It's expensive, but I expect this TV to last another 10 years.

There's no going back!
OLED can't do HDR..... it only goes to 540nits, HDR is 1000nits.

OLED is incredible for blacks though, nothing beats it.

Already do, Panasonic and Samsung OLED's are LG screens as far as I know, all other internals are their own.
Samsung don't do have OLED panelling. They tried it a couple of years ago and didn't carry it on. They use quantum dot instead.

All Sony's current range, including the newest 4K HDR 2016 models, are LCD.

If there had been a Sony OLED then it would have been my choice. But there isn't, so LG it was.

It would be pretty big news if Sony did produce an OLED model, but they won't be doing that this year.

LG need to bring their prices closer to that of LCDs as quickly as they can. Lower cost is the one thing in LCD's favour.
You might to check the Sony HDR bit. Have they got the HDR 10 standard or any standard? Do any Sony tvs go to 1000nits?

They do! Was down at a Panasonic training day recently and they were discussing this. The UHD Premium standard, which is what some of the Panasonic sets (and Sony too I believe) refers to is a nits rating of over 1000 and down to below 0.05 for HDR.
Whereas there is a separate spec for essentially the OLED sets that can go much darker but won't go anywhere near as bright, this is over 540nit and down below 0.0005 nits.
Other things come in to play to but that's the btightness side.

Load of info here. http://www.trustedreviews.com/opinions/ultra-hd-premium
Sony don't have it. It's Panasonic and Samsung that do.

The life of OLED panels isn't known, neither apparently is the life of LED backlights, HDR is thought to shorten the life of panels but again no one knows as they haven't been around long enough to see how long they last in the real world. There is quite a lot out there you can Google, Samsung say that their Quantum dot system is better than LG's OLED but they would wouldn't they.

As usual buy what you want from somewhere with a free or cheap 5 year warranty and forget about it, there will probably be something else you want by then anyway.
If I remember rightly, I think OLED has a lifespan of about 40,000 hours. Quantum dot is 60,000.

These imaginary figures are just 'made up'

And in any case, they only refer to the light output of the panel (either Plasma, CCFL, LED or OLED) dropping to an unacceptable level. In practice it's extremely rare to find panel failure caused by this, it's almost always an actual 'fault' on the panel, as opposed to 'old age'.

Older plasma panels did tend to change colour as they got older, a bit like CRT's used to Must admit my Hitachi/Vestel one never did, colours were still good when I scrapped it.

That is simply wrong. You are mistaken or out of date. OLED does do HDR. Though the figures are accurate, maximum brightness is far from being the whole story regarding HDR.

As I said elsewhere in this thread, there are one of two standards that a TV has to meet to qualify for the tag UHD HDR Premium, as specified by the UHD Alliance. One of which some recent LCD screens satisfy (Better (higher) maximum brightness but Worse (higher) minimum brightness) and the other which the latest OLED screens satisfy (Worse (lower) maximum brightness but better (lower) minimum brightness).

(BTW, I've read also that some of Sony's latest LCD sets do qualify for the standard, but for some reason they've chosen not to put that stamp on their range of TVs).

Link

I quote the relevant part of the article:

"There are two possible minimum specs. A minimum brightness of 1,000 nits, along with a black level of a maximum of 0.05 nits (20,000:1 contrast ratio), or a minimum brightness of 540 nits, along with a black level of a maximum of 0.0005 (1,080,000:1)."

In numeric terms, .0005 verses .05 at the minimum doesn't sound like a great deal of difference, but in practice the higher value is still a long way off true black and the OLED value is effectively true black. OLEDs, as you said, are the best for deep blacks.

And you have to look at the contrast ratio. It's much bigger (better) for OLED screens. 20,000:1 (LCD) vs 1,080,000:1 (OLED). That's better than fifty times the range of LCD.

My choice was the latter, because I dislike the greys you get instead of black with LCDs (and the halo effects that more recent LCDs get when they try to do black).

I tend not to watch TV with sunlight flooding into my lounge.

And... About maximum brightness:

That LCD figure is just under twice that of OLED. In practice it doesn't seem to make a lot of difference. Certainly in the two weeks I've had my TV so far I've not felt at any time that the brightness needed to be higher.

The only situation I can think of where it could matter is if you watch most of the time under very bright lights or in direct sunlight. Neither of those would be ideal viewing conditions in any case.

Well you'd better tell my TV it can't then, because when I watch Amazon 4k it quite clearly tells me it's going in to HDR

And another thing on HDR...

LG's 2016 HDR TVs support both competing HDR standards: Dolby Vision HDR, which uses dynamic metadata to optimise each scene, as well as the open standard, HDR10.

It's too early to tell which standard will work out for the best, but I don't think you can better that for future proofing at the moment.

The baseline for Dolby Vision is HDR 10.

HDR 10, you need a 10bit panel (colour standard DCI P3) and 1000nits of brightness.
Dolby Vision is 12bit panel, 4000nits of brightness. Neither of which exist. Some LGs say Dolby Vision this year. All it means is that it has the Dobly Vision chip.

And yes, you are correct about the LG front with the UHDA, I forgot it's because they have the lower end of the standard. I'd perfer to go for better colours though. It'd be good to have OLED black with the amazing colour other premium tvs give this year.

Sony is part of the UHDA. If their tvs meet the standrads, it makes no sense to not have the UHD Premium logo. It's like being part of FIFA and not playing in it.

HDR is the way to go and is future proofing yourself as much as possible. I know of something in the pipeline, but not for years to come and I'm not allowed to talk about it.

I too am interested in the E6 but apparently some reviews have said that upscaling on HD channels isn't great and since the majority of my programmes is HD that would be a deal breaker for me. So how good is it in that department?

I'm not aware of those reviews. All I can say is I've not noticed any significant issues. I also watch mostly HD, since there still isn't much 4K material around yet. Watching HD Blu Rays and HD channels on Freeview and Sky seem fine apart from the posterising on GoT I mentioned earlier. Since I also saw this on my old Sony and haven't experienced this on Blu Rays, I believe this is not a problem in the TV, but in the content and broadcast chain.

Can you can tell me where you saw the reviews you mention? Happy to read them and come back to you.

This was one although it needs translating to english. It has to be said that it was a good review apart from upscaling issue. http://www.hdfever.fr/2016/06/17/test-lg-oled-e6/

I have another issue that's been reported and I'm experiencing too.

Intermittent white flash. It's very fast (probably a single frame), if you happen to blink or glance away when it happens you won't notice it, and for me it may happen two or three times during the course of a 2 hour movie. For me it only happens on 4K/HDR sources (which is why I haven't noticed it till this weekend).

AVSForum: White Flash Thread

AVSForum Owner's Thread: White Flash, no HDR on Amazon, French 1080p issue

Summarizing:

In the US the white flash issue is reported to be solved by a firmware update. Unfortunately for me, that latest version they have in the US is not yet available in the UK (or elsewhere), so I can't confirm that it's solved.

The lack of HDR on Amazon is also said to be resolved by a firmware update. I've not tried 4K Amazon yet, so I can't confirm.

The French 1080 upscaling/motion problem is said to be solved by appropriate picture settings (turning off clear motion etc), and less visible/apparent on HDMI sources. Still unsure about this one, as my most used sources are HDMI connected. I don't watch much Freeview, it's not what I bought the TV for, nor have I used USB or screen share source. I did find the picture in standard settings by default had the "soap opera" effect anyway (in both 1080 and 4K) due to motion processing, so I've already turned off the settings and I'm not noticing a problem.

So, I await UK availability of the latest firmware with baited breath. I'll update as and when...
