dolby vision on windows

[Dream Driver 47]

is there any way to get dolby vision to work on my pc i've got a tv with dolby vision support so i want to make sure that games look good on it

I think you can probably get some extension to have Windows support Dolby Vision.

 

As far as content goes though, you'll probably have no luck. There's no any known major (or minor for that matter) streaming services that support Dolby Vision on Windows. You would be lucky if they even allowed streaming beyond 720p there. Unless you have the media locally - either ripped it off Bluray or pirate it somewhere, you'll probably have no luck watching DV on Windows.

 

For game though, getting the extension should work.

No, the windows extension is specific for certain display only and it is not support any Dolby Vision TV on the market. 

 

They is a thread discussion about this previously and many people try, include myself and the extension from Microsoft Store (you need to Google as it is hidden) did nothing.

The Dolby Vision extensions on the microsoft store do nothing. You will still only get a regular HDR10 output. One person on the forum claimed to have it working but hasn't been able to replicate it. But he used a receiver and we think it was just "forcing" the TV's picture mode into Dolby Vision with regular HDR content.

 

So no, not possible right now. And seeing as Dolby Vision is not owned by Microsoft i don't see it being implemented properly anytime soon.

that the said part about hdr. its a patch work and 98% of all hdr content faked hdr... which sucks to.

I don't really know what you mean. Regular HDR works fine. And most modern games ship with real HDR implementations. It's just Dolby Vision that doesn't work.

The HDR is fake or not, nothing to do with the format is Dolby Vision or HDR10. 

 

IMO most HDR content is well done, and not fake.

for video most hdr content is sdr and fake to hdr. very very common thing. its cheaper than doing proper hdr(ltt did a video on it awhile back).

 

i cant find any  spec info for hdr game devs use. there is no agree upon standard . it also very costly process. Again video ref it ltt did.

This is from the same industry that has lied about textures,fps , rez used and so on.

 

 

windows auto hdr  is a form of fake hdr.

ps5 does the same thing if your wonder. so any normal ps4 game  will use fake hdr on the ps5.

PS5 does support Dolby Vision, most HDR games on Windows are HDR10. There's no such thing as 'fake HDR' game, only fake HDR display. You can just take a look, it's night and day different with HDR on and off. 

 

Windows auto HDR is converting SDR input into HDR output, they are HDR, just not calibrated by people but rely on algorithm.

ps5 does not support dv.   https://www.techradar.com/news/ps5-might-get-dolby-atmos-and-dolby-vision-support-after-all-heres-why

hdr 10 is the worst of hdr.  it can have max 200 nit brightness. once again they play fast and loss with stock hdr 10.

its a  far less strict compare to dv or hdr+10.

Yeah it was Xbox my bad. 

 

But first, you can get way more than 200 nits on HDR10. If it stuck at 200 hit then it's the game HDR or movies implementation not the HDR signal problem.

 

In Cyberpunk you can get to near 700 nits which is show at 4:50 in this video during the guy calibration process. And that's not in Dolby Vision (in fact, Dolby Vision is not even reccomend in this title.)

 

 

And second, HDR in video is very different from HDR in photo is a tecnique where you fused multiple photos together to get more details of the darker and the brighter area. HDR in video is the use of meta data to instruct the display to output different level of brightness across the screen. It works very differently because with photo, you need to have the image of the details in the dark or the bright spot by the camera sensor, in order to preserve them - and thus, need to 'fake it' when that details are not available due to the limitation from the camera sensor.

 

With video, you've already have all the image data because everything is 3D and pre-rendered in the game anyway, your display know exactly what are there in that shadows or in the highlight. HDR in video is just a way to tell your display how bright or how dark those details should be rendered on the display. Usually this is done by people, but Windows auto-HDR is way in which that meta data is generated by the OS algorithm. It may not be as good but also not totally unusuable, doesn't take a genius to know that a big fire should probably be brighter than the monster in the shadows.

OG hdr10 . like i mention is the lowest lvl and tbh the worst type of hdr their is. seeing everyone play fast and loss with that. also sdr can look good or better  then hdr10.

that how low the bar for hdr10 is.

 

when i was ref the video. most older content. they use a type of software that add hdr  to it. watch the west wing on netflix. that added fake hdr . look at the light (fixtures) that the dead give away. .

modern tv with very old or low end recorded content. looks poor or   my eyes it burns....so they are going in after the fact and adding it.

 

 

like i said before i dont trust game dev to follow what i would say is decent hdr( hdr10+)

hdr master is very costly and every thing in the chain has to work correctly. but on master end and consumer on. which  most of the time it does not.

 To me it seems like you think that HDR10 has something to do with Vesa DisplayHDR 400, HDR1000 etc. But that's not the case. HDR400 and so on are Vesa certifications on how an HDR monitor performs. HDR10 is the video format, meaning it's in high dynamic range, at 10 bit colors. And HDR10 can be mastered up to 10.000 nits. The only difference is that Dolby Vision supports dynamic metadata. This basically means it can look better when the HDR display is not up to the mastering spec. But in no way is Dolby Vision a guarantee for better HDR image quality.

HDR10+ barely exists in the movie space and practically doesn't exist in the gaming space.

80% of all HDR content is delivered in HDR10, then maybe around 15% in Dolby Vision and the 5% that are left are HDR10+.

Consumer devices are almost always lower-end than mastering monitors. But that's why metadata and tonemapping exists. To map the mastered content to the capabilities of lower-end displays. HDR mastering is costly, but still accessible to mid sized indie studios.
