Forums - Sony - Here’s Why PS4K’s Ace Will Be HDR Support, More Than Any Resolution Boost

Does all 4k TVs supports HDR? The only ones I can find are Samsung TVs and they are expensive.

No, it's brand new. If it doesn't have that logo of Sony's version of it than it doesn't have it.


Thus, in 2016, “UHD Premium” HDR 4K TVs only consist of the 2015 Samsung and Sony flagship televisions, the SUHD JS9500 and the Sony XBR-X940C, and in the entire 2016 lines of SUHD and top-shelf 4K TVs from both companies. These would be the Samsung KS-Series SUHD models and Sony’s XBR-XD Series 2016 Bravia 4K TVs like the X850D, X900D and X940D.

For OLED: only one, the late 2015 EF9500 could be considered an HDR OLED model, with only the 2016 OLED Signature G6 4K TV being a truly HDR OLED model.

Either of those logos ensures:

  • Display resolution: minimum of 3840 x 2160 pixels
  • Color bit depth: 10-bit signal
  • Color Palette: (Wide Color Gamut)
  • Signal Input: BT.2020 color representation
  • Display Reproduction: More than 93% of the DCI P3 color spectrum
  • High Dynamic Range
  • SMPTE ST2084 EOTF
  • Both Peak Brightness and deep black levels of either more than 1000 nits and less than 0.05 nits of black, OR more than 540 nits of peak brightness and less than 0.0005 nits of black level. (This dual contrast standard is likely a direct sop to LG’s OLED technology, which can’t match the high nit levels of LCD/LED displays but can completely outmatch them in terms of how dark their blacks go, thus re-bracketing the range which constitutes HDR and deep contrast.

Note Rec.2020 allows 12 bit color as well and DCI P3 is only 73% of Rec.2020. Yet the new 4K UHD movie standard will adhere to 10 bit DCI P3.

(Well only the top 2 would qualify for the new standard)

Does anyone really care about HDR, that much? You're gonna tell me all of a sudden 1080p looks like shit. And I'm gonna be blown away with HDR. The example picture basically looks like someone just lowered the contrast, in the SDR one. This is basically like them just adding another speaker in surround sound setups. IF HDR was sooo important. Why wasn't it done when HDMI was first mapped out. The article even says "much closer to real life". So is there gonna be another upgrade to HDR in 20 years? UHDR?

It was already mapped out when HDMI came out. HDMI already supports 10 and 12 bit color since 1.3 The problem was LCD display tech was not good enough to get anywhere close to CRT tvs. Deep color (10/12 bit), Super white, x.v.color all were present in the ps3 already.

It was supposed to be in 4K tvs from the start, yet manufacturers jumped the gun as it was a lot easier to manufactor hi-res 8 bit panels than 10 bit color panels. It's the same situation again as HD ready vs full HD. They even started selling 4K tvs before HDMI 2.0 standard was set and currently there are still 2 HDR formats competing.

HDR is a much bigger advantage than an extra speaker, more like going from 8 bit to 16 bit sound. Then yes we'll have another step up to 12 bit color and full rec.2020, like going from 16 bit to 24 bit sound. It will be less noticeable.

Now some comparisons:

http://www.flatpanelshd.com/focus.php?subaction=showfull&id=1435052975#kFT57k0OP4G0ZoRd.99
If we really, really wanted to use the old EOTF gamma, developed for analog CRTs, we would need something like 14 or even 16-bit for HDR.

Today’s TVs use the so-called BT.709 color gamut, which can reproduce only around 35% of the colors that the human eye can perceive. The first HDR-enabled TVs are capable of reproducing most of the DCI P3 color space that cinemas use. DCI P3 covers approximately 54% of the colors we can see. But the industry has proposed a new far more ambitious BT.2020 color gamut that covers almost 76%!


This new HDR standard is said to cover at least 93% of DCI P3, or about 50% of the human color vision, up from 35%.

Woooo numbers. Still don't care about HDR. Especially that there's still upgrades needed. To reach 100%. All the comparison shots just look like someone set the contrast down. Because I know my 2009 LCD doesn't actually look like the SDR image, they show. The simulation images are pretty worthless. The same problem when someone is trying to convey 3D or VR. I'm still gonna say it's basically the equvalent to adding more speakers.

Just look out a window if you want 100% ;)
My mother in law still uses VHS, no need to upgrade.

I know there's no need. 40% of the US still uses VHS. From a study a year back. Not to mention that DVD's still exsist along side BD's. And shows still get released more on DVD, than BD. But trying to convince people, this hard. Shows that companies are out of major ideas. So now they gotta throw in 5 billion other things, into 4K. And even say "it isn't a gimick" In the article.

Okay Im sold on this.

 

Thats a huge differnce.

 

Don't think I've ever seen an image as poor as the one on the left on a 4k TV before. In the stores the display is always closer to the right hand side image.... Looks more like someone's played with contrast and brightness more than anything  

Edit: Oh that's video game graphics, ok then that's a different ball game. Does indeed look quite good 



Back at CES, AMD had a demo with two displays, one SDR and one HDR, running the same scene. Obviously we can't see the full difference as we see it on our own TV or monitor, but there we can still appreciate some of the details HDR brings.

It starts at 3:50

Great for the hadful of TVs which support it. Like mine :)

..... If you have a HDR compliant UHD TV. Which I do.

But lets be honest... even if it is true then it isn't a "huge advantage" at all.

Agree, games designed to work on SDR devices will at best enjoy a smoother interpolation, using also in the output some of those extra bits currently used just internally, but not a true higher range. Anyhow, if the rumour is true, it's most likely a novelty aimed to technophiles, to keep their interest alive on the product as it ages and the next gen is still far away. 4k and HDR support on non-gaming contents will probably be more effective, movies don't require as much GPU power as games, and once producers invest on HDR 4k cameras they'll use them, so the contents will come more easily, while game devs must rewrite some code and get new HDR texture libraries to get full benefits of HDR, and they also need scalable engines able to generate SDR output too for gamers not having new devices yet, unless they are fine to give up a large part of their potential sales.

O M G.... HDR makes a huge differnce.

I want to see it in person but if the gains are anywhere near that big... Im in.
