dolby vision Get Dolby Vision instead of HDR10 on Windows 10?
FinnishArmy posted a topic in Displays
Hi there! I have a Vizio 70" 4k which supports both, HDR10 and Dolby Vision. After testing both HDR10 (through Windows 10) and Dolby Vision (Through the TV App), I find that Dolby Vision on Netflix looks 10times better. Colours are not washed out on Dolby Vision like they are in HDR10 Dolby Vision is also much brighter than HDR10. I have my PC hooked up to a Dolby Atmos (not to confuse with Vision) receiver which I use to watch Netflix and other movies through my computer. I don't have an easy way to hook up my TV to the receiver unless I get optical (which only supports 7.1 and not bitstream). Anyway... Is there anyway to get Dolby Vision working on Windows 10 through the Netflix app? I pay for the top tier so UHD works for me. I've tried downloading the Dolby Vision app which only gives me a slider which supposedly turns Dolby Vision on. And that kind of works, when it's switched to on, the Netflix app shows "Dolby Vision + Dolby Atmos", but my TV is only running in HDR10 and when I try to load up any movie/tv show it just crashes the app until I either turn off HDR10 (which also turns off Dolby Vision) or just turn off Dolby Vision through their Dolby Vision app. Anyone have any success with Dolby Vision through their PC? -
Hi, I bought this TV on amazon - https://www.amazon.in/Redmi-inches-Ultra-Android-L50M6-RA/dp/B08Y55LPBF/ref=sr_1_4?crid=5V76LX1SG721&keywords=realme+tv&qid=1643346053&sprefix=realm%2Caps%2C629&sr=8-4 I knew that it would be terrible, it's a TV for a school anyway, but it claims to be Dolby Vision. The only time I saw pure blacks was when the backlight was off (duh). And except that it was edge lit, how can a Dolby Vision TV have a backlight? Don't you need pure blacks? Over that, it's not even IPS. They don't even disclose the display technology. It absolutely looks like a scam but it is by Redmi, a Mi brand, and I'm surprised they're getting away with this. Any idea how?

Hi, I have put a few posts up now asking for opinions on displays for PS5 and have got some really helpful advice. Originally I was leaning towards a monitor, however I have re arranged my room and now have room for a wall mounted TV. I went into Curry's (an electronics store here in the UK) and seen a TV which I loved the look of which I will link below. the reason I am posting on here is because the TV has HDMI 2.1 and a 120hz display however, according to a video online, Dolby Vision can't be used when running the TV at 4k 120hz due to a limit with the hdmi 2.1 bandwidth or something like that. Can anyone confirm this? Also is it worth getting the TV if I can't use the Dolby Vision on the highest setting? I want this TV to last me a long time hence why I like the idea of HDMI 2.1 even if it can't be fully utilized right now (because I doubt ps5 will hit anywhere near 4k 120fps).

Does anyone know of any Windows game that supports Dolby Vision? If you look at the Dolby website, there are tons of games showing that support Dolby Vision, but when I try those same games in Windows, I only get HDR10. It appears Dolby Vision support is only available for Xbox, but I'm not sure. tl;dr [Assumption] Windows does not natively Dolby Vision, only HDR10. Playing back Dolby Vision videos will down-convert to HDR10. Read for more info. HDR is many technologies There are many technologies which make up what we refer to as HDR: WCG ➡ Wide Color Gamut. Defines the location of 100% red, green, or blue. Doesn't affect the number of colors, just what color you'll see when you define an RGB color. HDR ➡ High Dynamic Range. The brightness of individual pixels. Today, the max seen is 10,000 nits. In real life, many things are at an even brighter nit value. HDR10 ➡ Typically graded at 1000 nits in movies, but many HDR10 games are graded for as many as 10,000 nits. Dolby Vision ➡ Typically graded at 4000 nits in movies. Dolby Vision is a way of compressing or tone-mapping HDR data to a display that doesn't support as many nits as the source content on a scene-by-scene basis. Once our displays can do 4000 nits peak brightness at 100% full-frame, today's Dolby Vision will be pretty useless. No clue how Dolby Vision is supposed to do anything in games, but TVs have a separate Dolby Vision mode. I think the way it maps out-of-bounds luminance data is different than HDR10. HDR10+ ➡ Samsung's version of Dolby Vision. Never seen this supported in any games. 10-bit color (or higher) ➡ This defines how many notches there are between red, green, and blue. 10-bit isn't required for HDR, but all media is designed around it as a minimum; so when you're in 8-bit color, you can still activate HDR using FRC (where it dithers to achieve the look of 10-bit color). As far as I know, your monitor needs to support it, but it might be an OS-level thing. BT.2100 Gamma ➡ Gamma is used because your eyes are more sensitive to changes in luminosity (brightness) rather color. All gamma curves are non-linear and weighted toward the bottom (meaning color values are separated more the further away they are from black). BT.2100 is the gamma curve used for HDR. Windows uses 2.2 for SDR content, but BT.2100 is a different kind of curve than simply weighting darks more. No clue how it works; this is all logarithms. HDR in Games Windows has a keyboard shortcut to toggle HDR: WIN + ALT + B. This works as long as you have the Xbox Game Bar enabled, and you can even specify if you want it turned on for only your main or all monitors. Many of today's games support HDR, but to actually view your games in HDR, you will sometimes have to enable HDR in Windows first. There are some games, like Elden Ring, which allow you to toggle the HDR setting in-game even if it's disabled in Windows. The majority of today's HDR monitors are LCDs which lose a ton of black detail while HDR is enabled. This is why you only want to use it when playing games that have bright, colorful scenes. With an OLEDs, Windows is a lot more tolerable in HDR, but even still, you most-likely don't want to enable HDR in Windows because 99% of apps (non-games) are designed for the SDR colorspace and don't look good when mapped to the wider color gamut of HDR. On top of that, the value #ffffff (pure white) is ridiculously bright in HDR. SDR Windows apps will give you some serious eye strain because they define white as the maximum brightness; supposed to be 100-200 nits, not anywhere from 400-10000. HDR in Videos I've played a number of HDR videos in Windows. You can use a plugin like MadVR to get it working in Media Player HomeCinema, but the Windows Movies & TV app natively supports HDR video including Dolby Vision. When playing Dolby Vision content in the Windows Movies & TV app, I'd expect it to change your display over to Dolby Vision if supported, but all it does is down-convert it to HDR10. I'm not even sure if this is a bad thing, but that gives me enough info to believe Windows doesn't support Dolby Vision at all. If it did, the HDR toggle would have 2 available options: HDR10 and Dolby Vision. That or it'd switch your display to the correct mode depending on the on-screen content. HDR History In the past, HDR meant taking multiple photos at different exposure levels and combining them into one to have a higher dynamic range of exposures. It resembled more of what the human eye sees rather than the 1 exposure level you get from a camera, but it also let you see things in the sky that would normally be clipped at the same time as you're seeing people in your photograph. HDR in Games before HDR Valve had HDR in the Source engine since 2005's Half-Life Lost Coast release (originally previewed in 2003), but that game engine was in SDR working in the BT.709 color gamut in 8-bit color. What this did was simulate the way your eyes automatically tone-map or adjust to light sources so when you saw something bright, it'd clip, but eventually come into view much like a camera would at a different exposure. This HDR refers to exposure, not pixel brightness.

I'll start off by humbling myself and say: I thought I understood color profiles and bitrates and how they worked with UHD formats such as HDR10, HDR10+, Dolby Vision, and HLG, but I'm not so sure anymore. So I recently got a 4k UHD tv (Hisense U9DG) which does support all 4 of the HD formats, as well as 4k 4:4:4. I also got a 4k UHD Blu ray player, the UBP-X800M2. I figured it was good enough to do what I wanted it to, but recently I noticed that it's not outputting at 4:4:4 color profile when I'm using Dolby Vision. It doesn't support HDR10+, but I do know I can get it to output 4k 4:4:4 when I'm using HDR10. So in tracking this down with Sony support they said that it doesn't support 4:4:4 at 4k 24Hz when Dolby Vision is on, only RGB color profile. Just out of curiosity, I also asked Panasonic if the DP-UB820-K supported 4k 24Hz 4:4:4 for Dolby Vision and they also said it didn't. They were also not clear about if HDR10+ supports 4:4:4 at 4k. I guess I'm just confused, am I just completely misunderstanding how Dolby Vision works, or is current 4k UHD Blu-Ray player technology just limited? My understanding of 4:4:4 was that it basically meant there was no chroma subsampling. Does Dolby Vision just only support RGB color space and handles chroma subsampling another way? Is Chroma subsampling an inevitability of Dolby Vision? I know Im talking about negligible differences, especially since I'm using a last gen tv at this point, but I just want to improve my understanding.

Hey guys I would like to ask if any of you have experience with using a dr screen on a laptop. I'm new to this. So far I have been able to stream HDR videos from youtube. Do you know what is "automatically process video to enhance it"? Does it enhance everything that appears on the screen? Also, is there anyway to control this. I am using a Thinkpad with a Dolby Vision HDR 400 screen. HDR certifications are certainly very confusing to me

Hey everybody! I´m currently living in Germany and I´m on the market to purchase a projector for my home cinema I was already almost certain to buy the Optoma UHD 60 but then I learned that it doesn´t have lens shift (only 15% vertically) . So I did some digging and found the Epson EH-TW 7400 which has lens shift (but 4k enhanced) but then reading some more I saw a review in which a guy says that this projector (Epson eh-tw7400) isn´t compatible with Dolby vision. I would like to know if that information is true or not as I bought the blue ray from sony x700 and not having a projector that can output the video would be a bummer. and as I´m already here taking advantage of the vast knowledge of this great community I would like to get some indication on projectors that can output 4k dolby vision that would cost no more than 2500 euros. Best regards the speaker in this set up is from Klipsch and receiver from Denon just in case there are any issues with compatibility.

Turns out Asus has released a monitor dedicated to editors on pure accurate colour gamuts. Supporting HDR10 and Dolby Vision at 1400 nit brightness. Would be nice to see Linus do a review on it. Article: https://www.tomshardware.com/reviews/asus-proart-pa32ucx

Hey So there is 3 formats that im seeing HDR10, HDR10+, Dolby Vision (aka. DV) for the movies i get. I know that the tv supports DV but can it also play HDR10 content in HDR mode? And for the HDR10+ Will it play those as a HDR10 (like a downscale or something) or will it not enable HDR at all? I'm just a bit confused on how the tv will handle these formats in the .mkv file. I know I want to aim for DV but if that isn't available what's the next best HDR to use HDR10 or HDR10+? tv is a LG OLED77CX

So I recently bought a Oppo 203 4K blu ray player and I am extremely happy with my purchase, since I bought it because people claimed it could activate Dolby Vision through usb, as long as the whole 4K bluray disc, was copied to a hard drive, which turned out to be true, so Yay! But, what I can't figure is why is that only Oppo has managed to pull that off? If they can then why can't others do it? Oppo has stopped manufacturing blu ray players, so as soon as those that are on the marked is sold that's it, no more blu ray or 4K blu ray players from them.

It seems every big TV will be 4k and - mostly - curved (I still don't quite understand the curved TV when more than one person is watching from two different points in the room but that's for another discussion. ;-)) So now the only differential appears to be the type of HDR in use? LG, Panasonic and Samsung all seem to have different takes on this tech. I'm guessing it's too early to tell but does anyone have any thoughts with HDR is better right now? I'm not in line to buy a TV until (at the earliest) the middle of next year when I hope things would have settled. But I'm interested how the market looks atm.
