To output 24 bit audio, your audio connection interface must support the bandwidth, and your audio receiver/speakers must support the 24 bit audio input as well.

Do you apply S/PDIF interface to connect your PC with speakers?
S/PDIF does not support DTS-HD MA or Dolby TrueHD audio as the data bandwidth is not sufficient.

Use HDMI 1.4 or above connection, and ensure your GPU card's HDMI port supports the 24-bit audio format as well. Otherwise, the 24 bit audio output is still not available.


Configuration test with SPDIF:
One of the previous tests with SPDIF and DTS-HD MA audio shows that DTS-HD MA is automatically switched to AC3 at 640kbps (5.1 channels). Which means that PDVD recognized the incompatibility and switched to playable (yet compressed) sound.

a) The output soundcard (ALC 1220, on mainboard AsRock x399M Taichi) should support DTS Connect.
I started to read into the technology, it should support 24bit/96KHz, with stereo downmix (which would be more than enough) and automatic conversion from multichannel to stereo.

However the receiving amplifier (NAD d3020 v2) does not appear to support any DTS or Dolby standards, and after reading that standard SPDIF probably cannot use more than 20bit i decided to not use SPDIF for movie audio.

In such situation:
- Either Source audio switched from DTS-HD MA to AC3
- Output is uncompressed but 48KHz 16bit
- On 3rd party applications Output might be indicated as 48KHz 24bit, but is in fact either compressed on SPDIF link, or reduced to 20 or 16 bits without notification


b) HDMI
Unfortunately the receiver is a monitor LG 27GN950 and does not support encoded formats, and HDCP is not present.

Frankly i wanted it for image (Calibrated RGB, BT709 or HDR 600), not sound. Supported audio is up to 48KHz 24bit and 2 channels. PDVD decodes audio to PCM, unfortunately its again 48KHz/16bits 2 channels.

Even when the output here isnt great, 24bit output was expected.
(I might try HDMI 2,0b cable just for the science)



c) Analog output from Soundcard
After few tests i decided to use internal sound card (ALC 1220) which does support output to 7.1 channels, up to 32bits and 384KHz.

To keep things efficient, output is set just to Stereo, 24bits and 48KHz, while AUX output is connected to the amplifier as an analog signal. This is optimal for both 16bit and 24bit sound formats.

However PowerDVD even in this situation still converts audio to 48KHz/16bit LPCM.



3rd party software does indicate 48KHz 24bit output, but I will check for as many details as possible.
Hello guys.

Some newer blurays offer this audio format. Most other formats are encoded in 48Khz 16bit and with lossy compression.

DTS-HD MA is apparently encoded in 48KHz 24bit and with lossless compression.

I spent some time and money to improve audio output for movies and one of the trick is to use same output format from audiocard, as is in the stream.

Unfortunately PDVD cannot switch to 24bit LPCM output format or at least it does not indicate to..

I tried some thirdparty solutions and I managed to get audio output in proper format. On cheap audio it wont make any difference.

On more expensive auido you might notice some details in 24bit output.

Any tips on this?
I just purchased steelbook with UHD BD + BD + Stream bundle with Ghost in the Shell.

UHD BD should be region free.

BD package shows its multi-region disk (ABC), unfortunately disk itself shows region A (America) while i reside in region B (Europe).

Both of my BluRay drives are multi-region, but PowerDVD does not allow me to set this. I can choose only one of those, and perform that change only 5x.


Back when CRT TVs were a thing, regions had importance, because you could not properly display PAL on NTSC system and vice-versa.

Now BluRays are all HD (1920x1080, 8bit Color, Bt 709, SDR), so the region requirement no longer makes any sense + my hardware should not have trouble with it.

In my collection is just one another disk which specifically requires Region B/C and enforces it through protection and its Fight Club.

Most bluray disks i own are either multiregion or do not enforce the region regardless of package information.

Is there any way how to set PowerDVD to multiregion?
hello.

Before i purchased Cyberlink PowerDVD license i read this:
http://blu-raydisc.com/en/Technical/TechnicalWhitePapers/General.aspx

I was specifically looking for any information about Intel SGX platform and, its simply NOT THERE. Documents are from 2018.


Would you like be so kind and point me to an official BDA document, which mentions this technology?


Thanks.
Quote Hello all,


Anyway, I was about to throw the towel until I read somewhere that Cyberlink dropped SGX support a while ago and now you can play a UHD disc on any PC that has HDMI 2.0a or DP 1.4 and HDCP 2.2 and that include Intel PCs running NVIDIA cards or AMD.


I dont know (yet) about PowerDVD requirement, but newest Intel CPUs dont support SGX anymore.

Edit: Also some reading:
http://blu-raydisc.com/en/Technical/TechnicalWhitePapers/General.aspx
Just one information...

With 11th generation of Intel CPUs, Intel SGX technology is no longer present.

https://community.intel.com/t5/Processors/11th-gen-cpu-why-no-SGX/td-p/1248815I would like to ask w

And i would like to ask whether PowerDVD will support UHD drives on platforms where SGX is not present.

Also this is not new information, this has been announced about 1 year ago.
Hello.

I would like to report an issue which is most likely Windows related.

Recently i purchased new UHD 4k HDR10 display:
https://www.lg.com/us/support/product/lg-27GN950-B.AUS

And its connected via Display Port 1.4 to AMD Radeon VII:
https://www.amd.com/en/products/graphics/amd-radeon-vii

I am currently waiting until UHD 4k certified Bluray drive arrives, and in the mean time i started to test HDR capacity of the display, using available demo 4k UHD HDR10 footage.

Results are however very bad, as the video image in fullscreen (and only fullscreen) is dark.

Settings are as follows:

4k @ 60Hz @ Display port 1.4 HDR @ 10bit color depth @ RGB 4:4:4 PC Standard @ HDCP 2.2 Enabled


Then I enable HDR mode as follows:
Settings>Display>Windows HD Color

Both "Use HDR" and "Stream HDR Video" are enabled.

In this situation the display announces that it recognizes HDR mode, and that it has switched to pre-defined Vesa HDR color profile, and in display OSD is stated that this VESA Certified DisplayHDR.


Then i open Power DVD 20 Ultra and navigate to the directory with 3 different demo movies, which are in UHD resolution, compressed in HEVC Main 10.

If the movies are opened in Windowed mode, they have correct HDR color gamut, but when i doubleclick for fullscreen, the brightness go very dark.

First i thought its an issue with display color profile, but no its not...

In windows HD color settings is a slider for HDR/SDR brightness balance.

If its set to 100, Desktop is quite bright, but every movie played using PowerDVD is very dark, regardless its HDR or SDR content.
If its set to 0, desktop is quite dark, but ALL movies (again both HDR and SDR) have correct brightness.

One of the demo movies i have behaves differently (its a MKV, others are MP4). If its started in fullscreen mode, the brightness is correct however when its set to windowed and then back to fullscreen, screen goes dark yet again.


On sunday should arrive new optical drive and i will re-test everything again with original UHD 4K bluray of Blade Runner 2049.


At this point it appears that the issue is either in Windows, or in Power DVD as the brightness is incorrectly set for HDR content and it seems to be inverted to the value it should in fact have.

I would like to ask you to look into the issue. So far the workaround for me is to set HDR/SDR balance to 0, have dark desktop, but the movies will have correct brightness.
