OLED VS HDR

The LG OLED do HDR just fine. Yes some of the Sony lcd panels go brighter, but my LG b6 goes stupidly bright with some HDR content, squint inducingly so, couldn't see how I'd need it any brighter to be honest.

Plus OLED is just a lovely looking picture once you have it setup right. It took me around 6 years to swap tvs from my panny plasma, and that's just because nothing looked as nice. Until now anyway.

But isnt HDR about the colour RANGE rather than just brightness. I have to say I still went for the E6 and am going to watch Narcos tonight as a test.

The 3:2 pulldown effect can cause issues, as the 24 frames don't fit evenly into 60 fps.

If I disable the pi from dropping the frame rate, then it outputs at 60fps or 3:2 pulldown.

No it's 23.976 fps.

23.976 is converted to 59.94hz "60hz" for your television using 3:2 pulldown which means repeat 3 frames, then repeat 2 averaging 2.5.

3:2 isn't used for smoothing out the framerate, it is a legacy way of getting a 24p (slowed down to 23.976) film or US TV show into a 59.94Hz interlaced US TV broadcast. Each frame is split into 2 fields and then shown in a 2 field, 3 field pattern, so every other frame effectively becomes 1.5 frames. A TV will then drop the extra field/half frame otherwise you'll get an undesired interlacing effect on a progressive film/show.
 
I have some empathy with deuse's point of view -
a quick "hdr standard oled lcd" google reminds us hdr-premium sticker has two variants

So how can OLED, with its brightness issues, qualify for HDR compatibility? Well, the UHD Alliance has got around the problem by introducing two standards, either of which qualifies you for UHD Premium status:

STANDARD 1: More than 1,000 nits peak brightness and less than 0.05nits black level.

STANDARD 2: More than 540 nits brightness and less than 0.0005 nits black level.

but on the otherhand 4k disks are mastered at HDR10 which can be in the vicinity of 1000nits.

so does that mean you cannot properly render all 4k disks on an oled ? riddle me that.
is there a database of brightness needed for different 4k disks (like the dynamic range db for cd's)

Most 4K content is mastered in Dolby Vision, which can go up to 10,000 nits although most content is mastered at 1000, 2000 or 4000 nits since the only display that can hit 4000 is a custom built one by Dolby that can only be leased from Dolby for high end productions.

What Dolby Vision actually does though is remap the nit values on a frame by frame basis to fit that of your TV. So if something was mastered at 4000 nits and a frame goes above what your TV is capable of the Dolby metadata will remap the nit value in that frame to match your TV, otherwise you would get horrible clipped whites.

HDR10 works in a very similar way except it is a piece of metadata that adjusts the entire piece of content rather than each frame, so Dolby Vision actually gives better looking images although HDR10 is an open standard.

I don't think HDR is brightness. Brightness is the black level.

You mean contrast (white level)
Click to expand...

contrast is the difference between the two. ultra Hd premium defines two sets of minimums as has been mentioned however the interesting part is the contrast ratio. It's not explicitly defined although it obviously is defined because black and white levels both are: Option 1) 1000nit brightness and 0.05 black level = 1000/0.05 = 20,000:1CR. but option 2 (OLED) 540nit and 0.0005 black level = 1,080,000:1CR

So yeah, all very well saying OLEDs dont do HDR but with a contrast ratio like that (and 540nit is still bright) IMO on a PQ point of view alone, it's a done deal for OLED.

That article is talking from the point of view of somebody trying to set a tv up and what the settings might be called on the tv.

Contrast ratio literally is the ratio of brightest colour the panel can produce against the darkest.
 
I've got a B6 OLED, I don't see any problems with the brightness. I've yet to see any LED TV beat the picture on it. I was watching The OA on Netflix which is a DV title; There is a scene where it goes from being dark to being a bright outside snow scene, it was so bright that both my partner and I had to close our eyes for a split second. To me, it seems strange to bang on and on about peak brightness. Surely you want deep blacks, smooth motion, accurate colours and a natural image.
 
Yep, I've also said here before the HDR has made me squint

People who say these sets aren't bright enough must watch TV with sunglasses on....Or more likely haven't seen one in a home environment :)
 
were you watching in the light or dark ?

both these articles discuss the same issue of oled max brightness, in particular with the current HDR10/ST2084 standard used for hdr coding
(Sirrel Squirrel -afaik DOLBY VISION is the next standard that will offer adaptive frame by frame hdr metadata
the bbc HLG coding helps too with more adaption for screens with different brightness levels,
a relevant article .. interesting lg will soon have a player, also

Warner, Universal and Lionsgate promise Dolby Vision 4K Blu-ray discs
)

Viewing Environment ConsiderationsOne of the often overlooked potential issues with ST2084 based HDR for home viewing is that because the display's various brightness (backlight and contrast) controls are already maxed out on HDR TVs there is no way to increase the display's light output to overcome surrounding room light levels - as is often done with SDR home TVs to enable different configurations for Day/Night viewing.
This is an issue as UHDTV/HDR as the ST2084 standard is intended to enable the creation of images with an increased spectral highlight range, not to generate images with overall higher luminance levels.
As has been stated previously, this means that for most scenes the Average Picture Level (APL) of HDR material will match that of regular SDR (standard dynamic range) imagery. The result is that in less than ideal viewing environments, where the surrounding room brightness level is relatively high, the bulk of the HDR image will appear very dark, with shadow detail becoming very difficult to see, as the eye's constricted pupil will just not be able to discern shadow detail.
To be able to view HDR imagery environmental light levels will have to be very carefully controlled. Far more so than for SDR viewing

4K Blu-ray vs Blu-ray Reveals HDR Is Too Dim for Daytime
This whole article wouldn’t exsist if Dolby Vision had been out first…instead of a one time HDR on off for hdr10, it does constant dynamic metadata ….basically it’s way better,fact….im not saying hdr10 is gross, just not as good…why we should wait to buy tech….

lol - how do you control formatting with new oc forum .
 
I'm really tempted to buy the e6 myself although I've only had my current tv (Panasonic ax802) for just over a year which seems a bit mad, I've always wanted an oled since they first show up and I would be gaining 5" screen size plus HDR would it be a worthwhile upgrade?

If I was you id wait until they release the new series of TV, likely to see price drops on the current models or improvement on the new range. Its not as if your TV is bad at all.
