Ive also been trying to work with Arkush on my own 3d bluray playback not working on windows 10.
I think the suggestion he makes about Intel drivers probably isnt a cop out on behalf of cyberlink and has some merit. Theres been allot of problems with GPU drivers for windows 10, especially with the change to WDDM 2.0.
If your not running 4K resolutions HDMI 1.4 is fine to use for HD resolutions.
Adapters dont really work. Dont use adapters. Theres allot stuff going on with say HDCP with bluray 3d playback.
The differences appear to be that Im running an nvidia 960 gpu and running hdmi 2.0, but it still wont work with 3d bluray playback for me. Ive tried running HD just at 1920x1080 but that doesnt work either. Generally NVIDIA are far more regular than Intel with GPU drivers and fixes but I cant in all fairness say its for sure not a driver problem. Anyway I'd like to see Cyberlink prove its 100% a driver problem if that ends up being the root cause with these 3d playback problems.
I know its not my display cos my sons xbox one can do 3d playback no problem onto the display.

Ah yes thanks for that correction - 9xx have HDMI2 but only so far the 960 can do full hardware deocding of HEVC. But for sure the posters nvidia 770 wont do HDMI 2.

Well after being stuffed around by Cyberlink support where the first ticket response I had to wait for, when it finally arrived it was boilerplate nonsense that asked for information I had already supplied.
Then after waiting again, they've now asked me to test it not under 4K but HD with 1920x1080. That doesnt work either on Windows 10, so atleast something has been learnt about the issue.
I'm hoping now it wont be weeks / months for it to be patched.

Mate I also have a Samsung curved 65" UHD TV. The thing is, If it's anything like mine you dont have display port. My only way of feeding my Samsung 4K UHD 65" TV 4K @ 60hz is through HDMI 2. The only GPU card that supports HDMI 2 is the Nvidia GTX960. And then, there is differences between the available HDMI ports on my display - for example the HDMI MHL port wont accept UHD colour ranges and HDR.
You dont have the right hardware to show 4K at 60Hz because you run a 770. Same with the other poster with the 980ti. None of those GPUs have HDMI 2.0 out.
The reason why lower than 60hz works for you is because through HDMI 1.4 you have enough bandwidth to send along the cable.

It all depends on your display device and gpu
FWIW, pdvd15 can do 4k @ 60hz with the right gear

So I raised my support ticket and Im now into merry go round phase of waiting days for the response, and if prior history is a lesson, it will say, were real sorry we stuffed up and weve passed this to our engineering team cos the issues are complex and it may take time to fix....And then they will close the ticket so their managers think they arent stuffing up their SLAs......Irrespective of actually not resolving the problem at Cyberlink its OK to close tickets before its resolved....
And beyond 3d not working heres a screenshot of how absurd the bug is with subtitles when running win10 300% dpi as recommended by default by Microsoft for 65" 4K displays......

Ive reported it in good faith before in betas but Cyberlink decided to not invest the effort to have it fixed during the beta and then released a prod based patch that doesnt fix it....

What build of pdvd15 are you actually running?
What is your gpu? First step is Id update the gpu drivers. Many win 10 drivers have been poor quality and its being fixed by amd/nvidia/intel post the win 10 release. Pdvd uses the gpu allot and in windows 10 its a whole new WDDM version 2

I deeply suspect that PowerDVD 15 wont ever support UHDBD. There is no GPU acceleration for UHD colour ranges. Same with ATMOS on the sound side.
Yes PowerDVD does do full gpu acceleration if you have a supporting card like the Nvidia GTX960 on 4k HEVC content, but only lower bit colour content. With UHDBD youll get UHD colour content.
So thats why Im convinced itll be a future PowerDVD release, say Powerdvd 16 that will properly address these things (I hope!)

By definition 2.0 is in stereo - left and right. There is no other channel. You can try to get a DSP to fake it but its just not going to be worth it in my view. Just enjoy the track as it was recorded in stereo.

Unfortunately I'm not having a very good set of experiences with PowerDVD. First it was issues on 4K 60Hz HDMI 2.0 not working at all and that required me using others players until Cyberlink got around to patching that. Players which by the way, are entirely free to own and distribute.
Then, since I'm really a fan wanting to promote how good my Cyberlink based HTPC setup is, I was more than happy to participate in the betas and given relevant and specific feedback about bugs in the betas. Its ironic in that I was OK to spend the hours doing testing on different builds just to have a good Powerdvd experience.
I find sadly, important bugs dont get fixed in the beta cycles. Like how people with 4K 65" screens in a HTPC setting cant watch and say MKZ or MP4 container videos with subtitles because of how DPI scaling makes the fonts way too huge and wrecks the viewing experience cos everyone runs somewhere near 300% DPI scaling on 4K 65" screens. Trying to configure custom font sizes in the Powerdvd setting has no effect in actual video playback and its bugged.
Now I find, on Windows 10, again with 4K 60Hz HDMI 2.0 that 3D Bluray playback wont work. So Im back to resorting to work arounds yet again. Now any time with 3D bluray movies that I might want to watch its back to something else to do that. Yes I have the latest 2003 build number installed. Yes Im going to do a service ticket for customer help. Yes Im going to have to wait weeks on weeks to see if I indeed get a fix or not. Yes I feel like its just another turn around the merry go round of stuff not working with PowerDVD.
Since when did production with the user base become the point to do software development and proper testing?

Hi Hicham,
Thanks for getting back to me. I'm pleased to be participating in the beta test.
My test config: Windows 10 x64 (WDDM 2.0 Directx12 feature level 12.1 and downwards), NVIDIA Geforce GTX 960 through HDMI 2.0 3840x2160@60Hz. This is a HTPC configuration with a 65" UHD 4K curved LED display as the monitor. In these setups Microsoft recommend a high DPI setting with the font scaling set to 300%, and Im running 300% as the default MS recommended config. Im running Cyberlink Powerdvd ultra with the beta patch.
Please refer to these screenshots:

c15a shows some aspects of my setup
c15b shows the bug where on initial playback the video is only shown in a small box despite it being set to maximised window and full screen. As reported after a few seconds it will initialise properly and come good with fullscreen showing. The test video is just a MKV container with the usual H.264 encoded video.
c15c shows the problem of ridiculously huge subtitle fonts. Again this is a MKV container with H.264 encoded video. No amount of changing the front size desired in the cyberlink font setting menu ever changes the actual font size display. On a 65" display sitting back two meters in a usual HTPC setup the fonts are way too big.
c15d shows the font settings for subtitles in cyberlink where even trying a font size as small as 1 results in the above screenshot problem. No amount of changing the font size actually does anything in playback
With what happens in bluray disc playback as opposed to MKV playback. Here the font problem with subtitles is not as bad, but its still bad and again user settings for font sized dont seem to be actually enforced by the video player. I cant provide a screenshot cos cberlink says the snapshot feature isnt supported in bluray disc playback.
The other thing to report, and I dont know if this is supposed to be a feature of Cyberlink Powerdvd v15, is that there is no GPU acceleration being done for 10 bit video playback. This is very important for HEVC playback and when UHD 4K HD blurays start being released soon it will all be 4K 10 bit HEVC. My GTX 960 supports full hardware decoding of this and Cyberlink is lacking in supporting it.
Also I find that overtime, say 10-20 minutes into playing back say a H.264 1080P MKV file if I enable subtitle rendering cyberlink powerdvd will always crash. It wont crash right away, but it will always eventually crash. The key is having subtitles enabled. Ive sent reports of the crash via the cyberlink powerdvd crash reporter to you at Cyberlink. In the meantime if I must see subtitles Im forced into using the freeware players media player classic htpc if I want to watch a whole video without being interrupted by it crashing under powerdvd beta.
Thanks

So Beta patch v1916 has a locked thread preventing testers from replying to it with test reports. Seems pretty silly to have a beta release and then not engage the community on the test results fellas 
Anyway I have a bug to report. Many people running large widescreen HDTVS in 4K will be running a non windows default dot per inch size so the text display is not silly small on the screen. In fact on large widescreen 4K TV's, Microsoft recommends a font scaling size of 300% over windows default.
The problem is that subtitles from say MKV container movies wont display correctly - they are literraly huge when rendered on the screen. No amount of changing the front or the font size will actually fix this either. So Im running 2160P resolution at 60 HZ over HDMI 2 on my Nvidia GTX 960. Its soo large that often all the subtitles wont display because theres no space on the screen to show it all.
Also when in bluray playback, the subtitles are not as large but again there it doesnt seem that any of the user settings are obeyed with font size, font type etcetc
The second bug report is that on initial playback of say a MKV container video with H.264 encoded film, initially the screen wont display at 4K resolution and just shows a small box of video. Then after some seconds it "comes good" and fills the whole screen. The way this initialization is happening looks amatuerish and I think it should cache itself all up and only then start displaying rather than displaying wrong pictures initially.

Same as you mate, a GTX 960

Good to know, I'm downloading v1916 now
|
|
|
Pjay I just use anydvd HD for removing constrains like prohibited nav options, cinavia etcetc
Theres no way cyberlink would continue to be licensed without the media cartels forcing the DRM onto them

If you only have the beta patch its not up to date. Cyberlink called the prod release the same version buts its not. You need the prod release not the beta release.
|
|
|
Your GTX 970 does support HDMI 2.0
However it uses an older video decoder that wont do full hevc hardware decoding
Make sure you have the latest patch from cyberlink cos the old version was bugged. You can download it from support / updates.
Then its good practice to do your geforce driver updates and general windows updates.
It should all work then.

Some updates on this beta cycle. I see you are calling this beta v1804 and also the one you pushed to production on 2015-06-23 is also v1804. However, they are in fact different builds with distinctly different behaviour.
With the prod build, I can now playback all the video that I could before in 1920x1080P at 2160P 4K using my GTX 960
This is awesome!
I have a high frame rate 60 FPS HEVC 2160P Main High Profile sample that plays very well no apaprent stuttering. Upscaling looks generally good. However I am noticing from time to time some stuttering in playback typically in upscaled bluray playback - I dont know the cause there was according to my hardware monitoring, the GPU, the CPU etcetc are all within limits.
We continue not to have full hardware decoding for the GTX 960 on High profile 10 bit colour HEVC samples. There is no way a CPU can handle high frame rate 4K content in 10 bit colour, so its a stuttering and skipping mess with powerdvd 15.
Anyway I am indeed pleased that 4K 2160P now works on most formats with the GTX 960

Some additional test results to report with my GTX 960 and 4K UHD display.
Oddly, even though bluray disc playback works at the 2160P desktop resolution when powerdvd is set to cinema mode, video files such as AVIs and MKVs that are not bluray discs do not playback - black screen with audio only - when tried in the same cinema mode. This is odd, because some as these avis and mkvs are much lower resolution than bluray disc, and not all of them use H.264 like many blurays - they use simplier video codecs like MP4-SP and MP4-ASP.

Some additional test results. When I said that under 4K desktop resolutions there is no video playback, this was true for the classic mode UI in powerdvd where playback results in a black screen. What I've since discovered, and I dont know if this beta only does this or if your prior production release does it as well, is that in cinema mode 4K desktop resolution most video will playback and display correct. So thats 1920x1080 bluray discs being upscaled etcetc to 2160P.
I monitored the telemetry during playback of some bluray disk content encoded content in AVC. With no movie enhancement, the cpu used about 3% and I could see the gpus memory controller, video engine etcetc being used. Then I changed the movie enhancement setting to strongest, and with the same bluray disc I was only peaking at 10% CPU utilisation and 40% GPU utilisation. So for now Ill can atleast playback blurays in 4k upscaling using the cinema mode UI layout of powerdvd.
I tried some native 4K HEVC, both my 8 bit colour main profile 60 FPS HEVC sample failed to play, and my 10 bit colour main profile 10 HEVC 60 FPS sample failed to play. None of this was GPU accelerated and the audio was a stuttering and skipping mess with the CPU being overloaded. Your going to need to support main 10 profile because thats what the enhanced bluray standard involves.
So the defects I see now are:
- In classic UI mode, 2160P desktop resolutions wont playback video - results in a black screen. Cinema mode UI will playback OK most video types.
- HEVC playback is not GPU accelerated even when using GPUs like the GTX 960 that does support full hardware decode. Which effectively means the video wont play cos the CPU cant handle 2160P 60 FPS HEVC high bitrate.
- 10 bit colour HEVC main 10 profile isnt played back. Main 10 HEVC 2160P 60 FPS can be played back under full hardware decode GPU acceleration on a gtx 960 without stuttering totally smooth using MPC-HC x64 with copyback DVVA2 LAV filters

Thanks for the patch
When I first ran it, something during the install process caused powerdvd to startup before it was finished. I already had a bluray disc in the drive maybe it tried to auto play it? Anyway Im not sure why, but powerdvd did startup before the patch was completed and before I selected the run powerdvd button on the patch finished screen
This resulted in all the UI of powderdvd not looking right and basically being broken
I simply re-ran the patch and this time powerdvd did not auto start and it went through the patch process fine. When I manually selected the run powerdvd button from the patch is finished screen, powerdvd displayed all fine in the UI
However my biggest gripe is that this new build does not fix the absence of video playback on HDMI 2.0 with 3840x2160 on suitable 4K displays and the Nvidia GTX Geforce 960. Your advertising 4K as being part of the feature set of powerdvd 15 and to me atleast, this has got to be the #1 critical issue to fix. Cyberlink support have been truthful and polite in confirming you folk can replicate the problem, and I'm trying to be patient while you folk deal with the technical issues. I will point out however your competitors in the free to use, free to own and free to modify/distrubute world of open source video all works out of the box at no cost with HDMI 2 4K playback. It seems self evident to me if you want to compete, youve got to have a better product than the free open source video players. I'm happy to work with Cyberlink on testing new builds, but its not going to make a good outcome if it takes months on months to get fix candidates to effected users.
