Re: X1 Yoga 3rd gen HDR display not HDR capable

Hi,

 

I have just made a few tests with Edge (Netflix/AmazonPrimeVideo) + Netflix App + Video App + Dolby Vision App.

 

Observation : 

If 'HDR is working', Dolby Vision App change should have a visual effect change on the played video (ex : dark or vivid).

Sometimes you also get a 'Dolby Vision' or 'HDR' caption at the first time of the beginning on the streaming.

 

My results : 

Edge/Netflix : working OK

Netflix App : working OK

Local Video Player : working OK (with the samples found in this thread)

Edge/AmazonPrimeVideo : does not work (or maybe I could not find any valid HDR content)

 

Strangely, when displaying the stream stats (with CTRL-ALT-SHIFT-D within Netflix App) it does not display HDR in the codec infos.

Per this video (https://www.youtube.com/watch?v=bbu8dstbhuQ)

HDR should display (hevc, hdr, prk)

but mine displays (hevc, dv, prk)

 

What about on your side ?

 

Regards,

Kristo.

 


are you sure Amazon Prime Video is meant to work with DV screens? This would be news to me. 

 

the real annoying thing is Apple doesn't support playing DV or HDR content from iTunes on PCs!!!!

Re: X1 Yoga 3rd gen HDR display not HDR capable

Hey,

 

I've not been able to find a clear answer after reading through a good volume of this thread.

 

If someone could provide a direct answer that'd be fantasic

 

My New X1 Yoga I purchased and got last week with the "14" HDR WQHD (2560 x 1440) IPS anti-reflective, anti-smudge, multi-touch with Dolby Vision, 500 nits" display, has no option for "HDR and WCG" under windows>settings>display

And when using Dxdiag, it states it has NO HDR or advanced color support.

 

It is my understanding that Dolby Vision is only displays with 12 bit color(most HDR is 10 bit).

Why do I not have an option for HDR and WCG?

That is the expected behaviour. This screen doesn't support HDR which is why you can't enable it in Windows's Display Settings. The screen is only 8 bit, not 12. HDR and Dolby Vision are competitors and your screen only supports the latter.

Dolby Vision is 12 bit though. 

 

And when you get Dolby Vision on a TV, and the content only supports HDR10(10 bit, hence the 10), Dolby Vision automatically downgrades to only display 10 bit color instead of 12....

 

So I know that Dolby Vision is supposed to be 12 bit. Are you saying the display Dolby Vision certified like advertised?

(p.s. they are not competitors. HDR is not a competitor to dolby vision... both are HDR... HDR is High Dynamic Range... It is a technology, its not made by a company or licensed..... Again... Dolby Vision is a type of HDR... Not a competitor to HDR...)

 

Now I want to know more about the display and why windows doesn't have HDR and WCG options for me, yet I've found numerous forum posts of people who say they DO have the option on their 3rd gen X1 Yoga

Dolby Vision supports 8, 10, and 12bit displays. Also, it supports color gamuts from REC709 to REC2020, resolutions from 1080p to 2160p, and brightness levels from 400nits to 4000nits. Dolby Vision uses the display to its maximum specs. The specs on a highest end TVs right now has 12bits per color, 4000nits brightness, and rec2020 WCG. These specs supported by dolby vision can go higher as display tech improves. What I mean is if they wanted to they could make Dolby Vision allow 10000nit peak brightness, which is crazy bright. But it's possible. The experience depends on thw specs but the Dolby Vision format is still supported.

In my experience, the X1 Carbon's Dolby Vision is pretty amazing. Obviously, you shouldn't be comparing it with high end TVs.

Well Dolby Atmos is 10 channel + 118 objects but your 2 speaker laptop also supports it.

 

This is what I was complaining about earlier, Dolby keeps ‘watering down’ their tech to the point even basic equipment can claim support.

 

Back to the laptop, the Dolby Vision app can only be installed on machines that have screens that meet its requirement, therefore the manufacturers have to work with Dolby to make sure they meet the specs. In other words it is incorrect to say these laptops don’t have a Dolby Vision screen. If it didn’t, the App wouldn’t install.

Yes but it’s worth noting the support is one way, i.e. not every HDR screen that supports Rec.2020 and 1000 nits supports Dolby Vision.
