Does anyone know if the LG C2 will work for games with the upcoming win11 update? Looks like they are building in native support.
 
maybe...
im on the insider, my tv has DV, plugins are installed, windows still doesnt see that the tv has DV. might be better with a monitor...
 
Right. I don't think this is going to work with TVs and dv gaming. I think something is missing like having to be a validated dv pc to work with certain monitors.

just like my amp supports VRR but not freesync/gsync :banghead:
we're combining two different ecosystems...

That is odd. Gsync at least should be VRR compatible. Alternatively use eARC for audio, then the whole VRR compatibility should not even matter.

to make it work with my setup i have vid to the tv via hdmi and then audio to the amp via dp>hdmi. no cert on the amp so they will not engage but it works with consoles.
 
I'm not clear on what the HDR certification info actually does. My LG C8 has always shown "not found" but worked fine in HDR (gaming and desktop). It seems like there are a lot of mixed reports - some people have HDR and Dolby Vision working fine without the cert showing up.

Wonder if the certification is necessary for media playback? Might need it to play back a movie file in HDR, for example, but not to output a game in HDR.

Also, monitor manufacturers may be much more likely to submit the certification info to Microsoft. TV manufacturers might not bother since most of their customers aren't connecting to a PC. From MS: "If you go to Settings > System > Display > Advanced display and your display doesn’t show as certified (it says Not found next to HDR certification), it might be because it doesn’t have an HDR certification, or the display manufacturer hasn’t published HDR certification information for your display."

it allows windows to feed it the right hdr/dv profiles. yeah you get hdr but you wont get DV unless setup correctly AND with the right equipment. windows DV is supposed to work now(on insider) but i cant get it working...
 
This Dolby Vision thing isn't really doing much except allowing better matching of bitdepth with scenes.
It would be better if Microsoft fixed gamma of SDR desktop so no profiles are needed.
All their nonsense causes is that people need to switch to SDR on some monitrs/TVs and on others they get black crush because some monitor makers like LG compensate for Microsoft's blunder which just doesn't work that well even for things like controlling desktop/SDR brightness. Some idiots at M$ did this SDR mode for HDR.
And why I cannot get excited for DV support.
 
been playing with it; still cant get it working but if i enable hdr, netflix (in edge browser) now shows DV but the color is all f'd up.
on a side note, while trying to fix this i got my atmos working in browser finally. used dell's oem Dolby Access app and license package to install the app and now it works! (bought license, never worked and app wouldnt install)
 
Reading through this thread makes me realize why most people don't care... because it's a pain in the ass to get working, most people would just give up, and they are likely oblivious anyway.
 
yeah, if you want DV to "just work", its a tv, blu-ray player and an avr. DO NOT add a PC into the mix...
ive been fucking with my setup since before xmas...

Issue might be with Edge currently: https://www.reddit.com/r/MicrosoftEdge/comments/1hucez3/dolby_vision_not_available_on_microsoft/

The whole thing is a clusterfuck. Hopefully Windows adding official support will eventually improve the situation.

So far, I only consume DV through my Shield Pro. It's the only device I've found where DV just works. It has the Blu-Ray codecs as well, unlike other players like Apple TV.
 
I give three shits. To get it working in gaming, and frankly that's all I would give a shit about, is impossible. So this update does nothing. I wanted to use dv on my pc for gaming only and it does not work. Oh well. I'll push out my three shits in the bowl tonight.

DV for gaming is completely pointless anyway. Games do their tone mapping in engine, there is no need for dynamic metadata and such for them.

What I am curious about how this would work for movie rips. If it is anything mike Dolby Atmos through their Access App, it is worthless because it does not work unless it is through official sources, games or some streaming services. For your own rips you have to bitstream, meaning passthrough, bypassing the Dolby Access completely into an external home theater to get the full Atmos effect. Which is fine if you have said home theater but if you want to watch movies late at night via headphones and want full Dolby Atmos height data, that doesn't work. You can only get the basic surround sound virtualised into stereo channels.

The only way I've been able to use DV on my LG CX is to put the rip on an external SSD HDD and plug it into the tv's USB port and play it from there.

There have only been 2-3 things that I have wanted to watch that way in the last few years.

I will admit though ... It looks good.
 
There are some external middlemen boxes, like some of the HDFury models, that can allow DolbyVision playback on devices that don't support it, like samsung screens/tvs. They are kind of pricey though. They also allow HDR10+ on screens that don't support it.

FEL is applied whether its LLDV or TV-led. (More about FEL below).

HDFury devices can allow you to play Dolby Vision content on a Samsung TV. Specifically, HDFury devices can be used to output Dolby Vision content as LLDV (Low Latency Dolby Vision), which can then be displayed on the Samsung TV as HDR10, according to a Zidoo forum thread. While Samsung TVs don't natively support Dolby Vision, HDFury devices can effectively trick the TV into displaying Dolby Vision content using this method.



Elaboration:
  • HDFury and LLDV:
    HDFury devices, such as the Vertex 2, can be configured to output Dolby Vision content as LLDV. This is a specific profile of Dolby Vision that is designed to be displayed on HDR10-compatible TVs.
  • EDID Manipulation:
    The HDFury device uses EDID (Extended Display Identification Data) manipulation to tell the Samsung TV that the incoming signal is HDR10, even though it's actually LLDV.
  • Improved Picture Quality:
    While HDR10 is the standard for Samsung TVs, LLDV can provide a slightly better picture quality due to its dynamic tone mapping capabilities, which HDR10 lacks, according to a Reddit user.
  • Alternatives:
    If you have an AVR (Audio Video Receiver) that supports HDR10+, an HDFury device might not be necessary, according to a Reddit user.
  • No Guarantee:
    It's important to note that HDFury devices can be finicky, and not all HDMI cables are compatible, according to a Reddit user.
  • Licensing Issues:
    Samsung's choice to use HDR10+ instead of Dolby Vision is primarily due to licensing fees associated with Dolby Vision, according to a video on YouTube.

Some external media players can play DolbyVision in a lesser format, but only certain ones support the full tone mapping , " FEL " .

For example, many of the Dune HD players won't play FEL (Full Enhancement Layer) quality, but will play MEL (Minimum Enhancement Layer) quality, which is still better than HDR10. They do have at least one android model with the chip that allows for FEL though, and there are a few boxes from other manufacturers that have the chip, too.

Dune HD players do support Dolby Vision, including both MEL (Minimum Enhancement Layer) and FEL (Full Enhancement Layer) profiles. However, it's possible that the issue is with specific file formats or configurations within your Dune player.



Here's a more detailed explanation:
Dune HD players are known for their extensive media format support, including Dolby Vision.


Both MEL and FEL profiles are part of Dolby Vision, and Dune players support them.


Ensure the Dolby Vision content you are trying to play is in a supported file format (e.g., MKV, MP4, TS, M2TS, ISO, or movie folder structure).


Verify that your HDMI settings on your TV and Dune player are configured correctly to support Dolby Vision. Some TVs require specific HDMI formats or settings to enable Dolby Vision.


Ensure your TV supports Dolby Vision and is correctly configured to recognize and display it.


Check for and install any available software updates for your Dune player, as updates can include bug fixes and compatibility improvements.


Dune HD players extract and transmit the Dolby Vision RPU (Render Processing Unit) metadata to your TV, ensuring proper Dolby Vision picture quality.

Also worth noting:

Dolby FEL (Full Enhancement Layer) does not require an internet connection. It's a feature used in physical disc releases of Dolby Vision content, specifically profile 7, and is applied locally on the disc. Streaming services do not utilize either FEL or MEL. While streaming services do use Dolby Vision, they don't employ these enhancement layers
Click to expand...

So apparently, you only get full Dolby Vision FEL from uhd disc material (or rips from it). While you don't need to phone home to get FEL, some media players require an internet connection though, for whatever reasons.

Streaming services commonly use Dolby Vision Profile 5. This profile is tailored for streaming and uses Dolby's proprietary IPT color space and dynamic metadata (RPU) to enhance color, brightness, and contrast. Major platforms like Netflix, Disney+, and Amazon Prime Video use this version of Dolby Vision to deliver HDR content to their subscribers. Dolby Vision Profile 7 is a more advanced version found on physical media like 4K Blu-rays, requiring specialized equipment.
Click to expand...


Another thing to keep in mind is that DolbyVision and HDR10+ as I understand it, are being mastered by experts on a per scene basis in order to micro-manage the settings and squeeze as much as possible out of a scene - given the limitations of HDR displays - . So, again, as I understand it anyway, they are making up for the lack of range HDR displays have, re-balancing brightness/contrast, levels, etc. compared to what "plain" HDR10 would show. The end result is specifically shaped, compared to sloppy DynamicToneMapping. I'm guessing that AI will have a role in mastering in the future, if it isn't already. Perhaps even in the displays, media boxes, or gpu/PC themselves on the fly/buffered.

Yeah, the different profiles are what trips up DV playback on some devices. Shield Pro is one of the few streaming devices that can handle Profile 7, afaik.

Streaming services tend to offer Dolby Vision with an HDR compatibility layer, allowing it to fallback to regular HDR for non-DV devices. I'm not clear on if this format really offers any advantages over regular HDR. Some services like Disney also seem to offer a DV version without the HDR compatibility layer. I've noticed that this version tends to be higher bitrate than the version with the HDR compatibility layer. For example, episode 11 of Andor season 2 is 15.2 Mb/s video on the DV stream w/o the HDR compatibility layer. Version with the compatibility layer is 11.1 Mb/s.

I believe these all work, in addition to a few disc players that can also stream

Ugoos am6B+
Ugoos am6
Minix u22x-j
Minix u22x-j Max
Fire cube 2nd generation
a particular model of the Dune player (I think their android one)
Zidoo model that has RealTek RTL1619DR chipset
Any android box with certified dolby vision version of s905x4 chip will probably work with coreelec for FEL / DV Profile 7 <~~~ EDIT: this may only work with S922X-J devices such as the AM6B+

Edit: The Dune Pro Vision 4k model, specifically, according to reports, can also get dolby vision FEL , using corelec.

Both the Sony UBP-X700 and UBP-X800 UHD Blu-ray players support FEL DV, and can play/stream MKV files over a network.


From what I understand, the Shield Pro 2019 doesn't play FEL:

"The Shield lacks a secondary video decoder to process the second layer on profile 7 videos, so it will only apply the dynamic metadata onto the base layer. For many movies out there, this is fine as the secondary layer contains no extra information (MEL). But for the ones that have residue video information on the secondary layer (FEL), this information is ignored on the Shield"
Click to expand...

. .

reddit reply from a month ago:
The shield is capable to play Dolby Vision profile 7. It just discards the FEL (Full Enhancement Layer). To explain it: Dolby Vision Profile 7 has 3 layers. The Base Layer (BL) plays just fine on the shield, its like a HDR10 fallback. Then it also has a enhancement layer (EL), this can be either FEL or MEL (full/minimal) enhancement layer. This part has additional information that enhances the quality. It also has RPU (Reference Processing Unit), this part makes sure that the BL and the EL layer are matching with each other.

The Shield ignores the EL and RPU and just plays the BL layer, which gives less quality.

If you let the dolby vision profile 7 on the shield be live converted to dolby vision profile 8.1, you won't get the FEL layer with the most important information. It will extract the HDR10 base layer (BL) and merges it with the RPU metadata to create a Profile 8.1 stream. The FEL is discarded because Profile 8.1 does not support enhancement layers (FEL or MEL) because it is a single-layer format. The resulting stream contains HDR10 video with dynamic metadata, but it lacks the extra color and brightness detail provided by the FEL.

And besides that, the Shield still has the infamous red push problem, which is a real big problem.

If you want as much picture quality as possible, your best bet is to use a Ugoos AM6b+ with CoreELEC, it can handle all the dolby vision profiles and layers like FEL.

. .

The red push problem refers to an issue where red tones in HDR10/Dolby Vision content are oversaturated, this leads to inaccurate color reproduction.
The Nvidia Shield processes the color in HDR modes and it seems to push red tones too aggressively. That is why the color red appear overly vivid or intense, resulting in unnatural-looking skin tones and overall color balance.
It is not always noticeable, but it is something that is there and just makes the picture less accurate.
Click to expand...

The shield also lacks the AV1 chip to play HDR on youtube, btw. It's still a decent box. I retired mine to my bedroom TV now.

FEL capability is valuable for uhd discs that have FEL DV, or rips of them that include it.. MEL provides some basic advancements over HDR10, but doesn't enhance the scenes as much. I'm not sure how streamed show's Dolby Vision Profile 5 output compares, technically, and generally, to MEL.

Interesting! I'm obviously a bit out of date. I've been using the Shield for a few years now, and I've been looking for a reason to replace it so I can retire it to my family's cabin where we've just been using the TV apps.
 
Most of the models I mentioned are already dated, and corelec is shifting gears to a different product too I think, so it's functionality will probably be frozen at its current state, though that works for now. The emphasis of media boxes is mostly on streamed shows, which aren't FEL uhd discs, and dolby vision FEL chip requirements and licensing requirements don't help.

I think Dolby Vision and HDR 10+ mastering are sliding output values on a per scene basis (perhaps even area/object basis within each scene using tracking software) to help compensate for how limited HDR ranges are on current displays. Kind of like a human micromanaged and strictly defined dynamic tone mapping that is restricted to baked in values per scene. As it is now, that requires people to sort of compose (master) the pre existing scenes.

Hopefully as we get more capable hdr screens in the future, and hdr 4000 capable ones (ultimately hdr 10,000), we won't have to rely on dolby vision and hdr 10+ to spice up the output. I also wonder if AI will have a more prominent role in tone mapping HDR (and sdr to hdr) at some point, to get results comparable to dolby vision FEL, or better.

As much as people bemoan samsung's lack of dolby vision support, they are trying to make a comparable license free version with HDR 10+. I've also read that they and google, and some other partenered companies are trying to make a license free tech comparable to dolby atmos. The lack of licensing fees not only helps consumers with it being less restrictive, but also content creators.

Yeah, I did some more research after your post. The Ugoos am6B+ seems to be the golden goose. It's still produced, and I believe it's the unit CoreELEC focused their efforts on. Sounds like it was a bit of a happy accident that the DV profiles and licenses for that specific chipset were opened up. They are moving on to other projects, but it sounds like they have the AM6B+ in a really good state where it can play everything. I have a lot of UHD Blu Ray rips, so I ordered one to give it a shot. Been looking to move away from Plex with their recent changes, so it's a good time to give Kodi a try. No AV1 decoding or streaming apps on the CoreELEC build, so it's just a pure media server streamer. I'll keep the Shield Pro around for streaming apps (or maybe move it to the cabin and get something with the AV1 chip) and look into Emby for remote streaming.

HDR10+ is a nice option to have. It does do dynamic metadata, but it doesn't give the colorist full control like DV. Some TV manufacturers like Panasonic are supporting both HDR10+ and Dolby Vision. While Samsung did make HDR10+ royalty free, it's not totally free. Anyone who wants to use their certification mark has to pay an annual fee. The Dolby Vision royalty fee is said to be less than $3 per TV set. I think most people would pay that given the option. Still, between DV, Atmos, and other options, the fees could start to add up. Maybe TV manufacturers could start adding these things as a feature users can pay to enable in software. Let the customer decide what they need and want to pay for. That's probably a pipe dream :LOL:

There are two Dune brand players (not all of their lines) that also have chips that work with the corelec "hack", one is all dune linux based, another has a dual boot option between Android os for streaming svcs and dunes Linux os. (And both auto boot corelec from a SD card or USB flash drive, respectively).

Seen those, but from what I gathered they play DV similar to the Shield Pro, ie w/o the FEL layer.

You have to set them to boot from their SD slot or USB port, respectively. Then they load corelec environment which plays FEL layer. There are some tutorials online and on youtube, linked in their respective avs forum threads.

Just to update the somewhat off-topic DV FEL playback as pertains to a few stand alone players, from what I've gathered, the ugoos AM6B+ is the best, least caveats and fastest functionality both due to the player specs and the fact that the corelec dev is developing specifically for it. The other dune models work, and the dune homatics one works better for android apps , but the dune ones have some caveats/wrinkles, aren't as streamlined as the AM6B+ for corelec specifically.

So essentially, you can't get it all in one machine, so some people use AM6B+ for rips on corelec and then use their smart TV apps or some other stand alone android based player (e.g. your old nvidia shield) for android streaming apps. The dune homatics box can boot into an android environment, but according to some feedback I got, then you aren't getting quite as polished of a corelec experience compared to AM6B+.

. . . . . . .

I don't know what windows 11's DV support will be able to do. Streaming services don't do the highest quality Dolby vision FEL/Layer 7 to start with, so those will probably work. For DV rips (or PC uhd disk players) on PC, I doubt windows will play the FEL Layer.

Some people used MadVR plugin in mpc-hc player to some effect, rather than windows HDR.

To play HDR content on your PC with MadVR, you'll need to configure both Windows and MadVR. First, ensure Windows HDR settings are disabled, as this can interfere with MadVR's tone mapping. Then, configure MadVR to either passthrough HDR metadata to your display or to perform its own tone mapping using pixel shaders, ensuring "output video in HDR format" is enabled.



Detailed Steps:
  1. 1. Disable Windows HDR:
    In Windows settings, navigate to System > Display and turn off "Use HDR" and "HDR video streaming".

  • 2. Install MadVR:
    Download and install the K-Lite Codec Pack, including MPC-HC and MadVR.


  • 3. Configure MadVR:
    • Open the MadVR application (usually found under K-Lite Codec Pack).
    • Navigate to "Devices" and select your display device.

  • Under "Properties", set PC levels to 0-255 and bitdepth to 10 bit or higher.


  • Under "Calibration", select "This display is already calibrated".

  • 4. Configure Kodi (if using Kodi):
    • Open Kodi and go to Settings > Player Settings > DSPlayer.
    • Set "Video Renderer" to MadVR.
  • 5. Test HDR playback:
    • Play an HDR video and use Ctrl+J to view rendering stats in MadVR.

  • Ensure your GPU and display are capable of supporting HDR and that you're using an HDMI 2.x port.


  • If the colors look washed out, you may need to adjust your TV's settings or verify proper HDMI Black Level or Ultra Deep Color settings.
Important Considerations:
  • Display settings: Ensure your TV's HDR mode is enabled and that you're using the correct HDMI input.

  • GPU and HDMI: Make sure your GPU and HDMI port support HDR and that you're using the appropriate cables.


  • Windows HDR settings: Disabling Windows HDR is crucial to avoid conflicts with MadVR.


  • Tone mapping: MadVR can either pass the HDR metadata to your display for tone mapping or perform its own tone mapping using pixel shaders.


  • Testing: Use test videos to verify that your HDR setup is working correctly.


  • Updating MadVR: You can update MadVR by downloading a new version and copying the files into the relevant directory.

That's the conclusion I came to as well, so I've got the AM6B+ on the way. Plan is to use that purely for playing on local network from my personal server, and keep the Shield Pro for streaming apps. The way I look at it, AM6B+ is basically a Blu-Ray player without the hassle of discs. The Dune players look a bit nicer aesthetically, but I should be able to hide the AM6B+ well enough that it'll be a non-issue. I'm also looking forward to trying out Kodi, as the interface looks better than Plex or Emby. I'll keep my server running one of Plex or Emby for remote streaming. Plex has kinda gone to shit with the price hikes and data harvesting, so it'll probably be Emby.

I was aware of some of that stuff already, but it seems like I was a half step ahead of you on that journey currently. Mine arrives tomorrow. (I was going to return it if research and inquiries had indicated one of the other players was a better option).

I agree on the other point, too. I swapped from plex to emby a long time ago for QoL issues. I still use emby to feed my shield in my bedroom, but moved on to Linux based player with its own video library at my living room tv. Since I'm replacing that player with the am6b+, I'll either sell the Linux media player I've been using or connect it at my PC's main screen on another HDMI input.

Taking it slow. Spent time with family over the weekend and I have projects going on, but I'll build out the software in the box a little at a time this week. I know there are addons for coreelec for youtube (with some fiddling), twitch, and OTA hd tuners like my hdhomerun for OTA local channel playback (my local news), but I'm not sure if they will work with am6b+, which is often quoted as a local playback only machine. Will have to see. If not, I'll probably throw my old nv shield on another hdmi input and swap to the am6b+ just for movie watching.

I have a sofabtaon remote which has a sort of mouse wheel button in the middle which allows me to switch between device profiles on it's little LCD screen, where activating a profile swaps device inputs after I take the time to set a profile up. e.g. swap between AVR inputs/TV inputs for different devices, can also swap to a profile just for my LG TV's webOS. It turns everything on or off at once, too. It's also nice because I can use it to cycle through user picture modes so that I can micromanage how the output looks depending what I'm watching, or the time of day/ambient lighting.. I sacrificed one mode (sports mode) to be zero backlight and brightness, to black the screen out with a "blackout button" I assigned, which I do when I go afk from my oled or if I'm listening to music or podcast type stuff with static screens.. I hit that button again and it automatically goes back to game named picture mode.


This forum and thread has some good info:

There are some good guides and videos online too.

I like emby's posterboard options, and that it can list things by folder name rather than filename, among other things that I'm not a fan of with Plex. They both provide a similar function though.

The linux based media boxes have their own sharing and library systems, even if not as polished in some cases, they work fast and well, and may provide enhancements as well as just functioning better on the linux based OS than emby or plex. Coreelec's media library function is supposed to look good though, and that OS has different custom skins you can add.
 
tossing in the towel for now. cant get DV to work correctly and Atmos is causing stupid drops when switching between even the most basic formats (like during youtube commercials) and is getting annoying, turned it back to dts:x.

The point that drove down this rabbit hole, getting back to the main thread here, is that Dolby Vision is different things depending on the source, and depending on the destination hardware and licensing. So what windows DV may be capable of, or chrome/streaming content shows on windows, can be different from what other sources/devices would show, level of enhancement wise.


"The problem with Dolby Vision is the complexity of the way Dolby roll out its DV implementation. Believe it or not, there are at least 6 known profile levels."

  • Dolby Vision Layer 7 (FEL) exists on some uhd discs (and rips that include that layer metadata) and is highest/most enhanced output quality.

  • Dolby Vision Layer MEL (Minimum Enhancement Layer) quality is what DV layer 7 defaults to when a player is incapable of playing the FEL layer, due to hardware restrictions/licensing.

  • "Streaming services commonly use Dolby Vision Profile 5. This profile is tailored for streaming and uses Dolby's proprietary IPT color space and dynamic metadata (RPU) to enhance color, brightness, and contrast. Major platforms like Netflix, Disney+, and Amazon Prime Video use this version of Dolby Vision to deliver HDR content to their subscribers. Dolby Vision Profile 7 is a more advanced version found on physical media like 4K Blu-rays, requiring specialized equipment. "

LLDV (Low Latency Dolby Vision) is a specific mode of operation for Dolby Vision (DV) technology. It's designed to reduce latency in DV playback, especially for source devices and professional AV equipment. LLDV allows devices to handle Dolby Vision tone mapping and other processes more efficiently, potentially improving image quality on certain displays and reducing processing load on the display itself

. . . . . . . . . . . .

"For games, Dolby Vision typically uses a single-layer profile, such as Profile 5 or 8, which is optimized for player-led (LLDV) implementations. This is often preferred by streaming services and some media players. Dual-layer (Profile 7) implementations, which might be used in 4K Blu-ray discs, are less common in the gaming context"

A game could say it's dolby vision but then default to what is essentially a HDR10 base layer, too.

According to xbox support site: "On Xbox Series X|S, Dolby Vision is available for streaming media apps and playing games. On Xbox One X and Xbox One S, Dolby Vision is available for streaming media apps only. Dolby Vision is not supported on the original Xbox One."
"The Xbox Series X's Dolby Vision support relies on software processing, which can sometimes lead to limitations compared to dedicated hardware implementations found in some 4K Blu-ray players"

Even considering what I said above - if windows was limited to the streaming version of Dolby Vision, it would be nice to have, if they ironed out the wrinkles. Especially if it was solid and pc games started being developed with it. I wouldn't use windows for uhd/rip DV media playback if losing the highest dolby vision enhancement bothers you.

The MadVR method I mentioned earlier still might produce some decent results, as a workaround. This guide is dated but shows the general idea: https://forum.kodi.tv/showthread.php?tid=209596

Personally , at PC, I'd just use more than one monitor and swap my OLED to it's smartTV OS or to an external player on one of it's inputs, using the tv as the "media window". It would work a lot cleaner with less hiccups. The benefit of dolby vision on pc for me would mostly be if games started to utilize it at some point.
