So, according to Dolby, content is mastered on displays that have worse dynamic range than those this same content is shown on? Good thinking, I'd say.

You are free to implement Higher or lower specs, either open and DRM Free, or proprietary Crap to hold everyone who believes your bullshit hostage
This is also just one reason that Microsoft's DRM makes their License Null and Void
You cannot Violate National Security and hold everyone hostage by making everyone vulnerable to attacks by creating perpetual backdoors under the guise of DMCA Laws that you only created to prevent anyone else from doing what you yourself are doing
I watched an interview with the Sony rep regarding this display and they used their own in-house tools to master content for this prototype to take advantage of the 10K nits maximum. In particular, the PS4 Pro outputs metadata up to 10K nits.
High peak brightness doesn't mean that standard background on white web page would be shown at 10 000nits.
It just allows us to have proper specular highlights in chrome bumpers of the the cars etc. Ie. those little few pixel sized highlights that you see all the time in real world when you walk down the street in a sunny day.
Only if your display brightness is cranked to max and your OS is stupid about it.
A complaint I've seen elsewhere is that in HDR mode W10 sets the maximum brightness level for normal desktop white at a level suitable for a relatively dark room not one with really bright lighting/outdoors sunlight and doesn't provide an easy way to change if.
When you output SDR, sure. If you output in HDR mode, you would hope that Windows does some magic to reign in the desktop into the 0-100/120nits range, as to not cause crazy results.
A different transfer function is used to allocate more bits to the important parts, and less bits to the less important parts of the brightness range (we already do that in SDR with the typical gamma curves as well)
On that note, displays are also not designed to show a full 10,000 nit white screen, because that would be truely blinding, so I would assume that to be literally impossible.
Indeed, very high brightness allows the monitor to show "whiter than white" highlights and details, like sunlight reflections off shiny surfaces, while high contrast helps to show very deep "blacker than black" blacks, and more grey shades in gradual transitions from white to black or bright to dark colors (however for that to work well you require at least an 10 bit display, or else you suffer the horrors of color banding).
The above specular highlights are not often "pixel sized" (especially in 85" screens) though, and for all the above to work the content needs to have been mastered at least at a level of quality and detail of what your TV/monitor can support. In bad quality content you will see no to barely any difference. I am also quite sure that under a testing or calibrating (probably not under normal use) mode it should be possible to expose all the nits of this screen, preferably with adequate eye protection.
Hey Anton! Good piece on the technical side, but you missed out on an important piece of information. What does the image feel like? From your subjective point of view, does it look awesome? Is it a big step? Do you actually wish you had that in your living room?
"A big question is whether this is something that is eagerly awaited by the industry in the foreseeable future because in addition to peak luminance, display panels need to properly support large color spaces"
This is nothing new. SIM2 (Italy), Vicomtech (Spain) and the University of Warwick (UK) showed a real-time HDR video pipeline to a 10,000nit display at IBC in September 2016 and at NAB New York in December 2016. You only need sunglasses if you are looking at 10,000nits in a dark room ... which such a bright display it is actually possibly to finally be able to see the beauty of HDR without having to paint the walls of your house black.

Really nice!You need sun classes when looking film that is shoot in sahara...

It's one the of the reasons for HDR: to show Sahara (or the Sun) as it is.Scootiep7 - Thursday, January 11, 2018 - link

I agree, you will need some major sun screen. I wonder how horrible the power draw is going to be.0ldman79 - Sunday, January 14, 2018 - link
That's how dynamic contrast works, right? The TV pulls so many amps that the other lights in the house dim?eSyr - Thursday, January 11, 2018 - link

You are free to remove DRM whenever it Violates "YOUR" National Security!Yes, DMCA advocates are on my Terrorist Watch List!

But isn't level 1024 (10-bit) peak brightness, whether on a web page or a bumper?DanNeely - Thursday, January 11, 2018 - link

"A big question is whether this is something that is eagerly awaited by the industry in the foreseeable future because in addition to peak luminance, display panels need to properly support large color spaces"If the display supports remapping from ACES (https://en.wikipedia.org/wiki/Academy_Color_Encodi... it can in theory perfectly emulate all gamuts encompassed within its own physical gamut volume.

So your comment about multiple HDR techs is outdated, didnt they merge the specs just a few days ago?trueHDR - Thursday, January 11, 2018 - link
