Intel(R) Arc(TM) A770 Graphics does not automatically recognize HDR videos (HDR 10 OR DOBLY VISON).

AL_JP — Mon, 04 Dec 2023 04:51:40 GMT

MY Intel(R) Arc(TM) A770 Graphics does not automatically recognize HDR videos (HDR 10 OR DOBLY VISON...ETC).

Currently known display output devices are as follows
Yamaha's RX-A6A AVR + LG C2 48 OLED TV
Confirmed to work properly with HDMI 2.1 FRL, but unable to output the correct HDR signal format through the ARC 770 graphics card.

Hopefully this will be resolved in a future driver update.

Hello AL_JP,

Thank you for posting on the Intel®️ communities. Since you are having issues with your Intel® Arc™ A770 Graphics not automatically recognizing HDR videos. In order to enhance comprehension of the circumstances, kindly respond to the following inquiries:

Is the graphics card an Intel Branded Card or is it from another brand?
Before installing the graphics driver to version 31.0.101.4972, did you perform a clean installation with Display Driver Uninstaller (DDU)? Otherwise, follow the article How to Use the Display Driver Uninstaller (DDU) to Uninstall an Intel® Graphics Driver, and then install the driver 31.0.101.4972.

Keep me informed of the results.

Regards,

Andres P.

Hi, there.
Graphics Card by ACER, Model Name Predator Arc A770 16G
I installed the 31.0.101.4972 driver after a fresh install with WIN11 OS.

If running the DDU may improve the problem, I will try it again and report the results, but it should not be necessary to run the DDU in an environment where the OS has been reinstalled.

Waiting for good news

I have tried running DDU and reinstalling the driver, but the problem persists.

For reference, here is the IntelGFXFwUpdateTool.Log and the support information for the monitor I am using.

Hello AL_JP,

Thank you for your time.

We would like to proceed with the issue replication, but first, we would like you to share a video showing the issue, for us to try to reproduce it as accurately as possible.

If you use a YouTube video or something similar to test if HDR works, also will be useful to provide us with the link or file for us to test our LAB with the same video.

I used a UHD Blu-ray disc (DOLBY VISION CES March (2018)) for testing, and here's one of the smaller file snippets in hopes of identifying the problem as soon as possible

Because the size exceeded the upload limit, I put the file in GOOGLE DRIVE.

Hello AL_JP,

Thank you for the video, that will help a lot.

I will need some time to start with the issue replication, and as soon I have the results I will let you know.

General information: Whitepaper | Beyond resolution – HDR, WCG and HFR

From the SSU report in the first post:

Current Mode: 3840 x 2160 (32 bit) (120Hz)	Video files are rarely available with a refresh rate of 120 Hz. Actually only if you have recorded videos yourself this way. In all other cases this refresh rate is not necessary. This could affect automatic HDR detection. However, the latter primarily depends on the software player and the used DirectShow Rendering Filters.
HDR Support: Supported	System has recognized the suitability of the signal chain for HDR
Display Color Space: DXGI_COLOR_SPACE_RGB_FULL_G22_NONE_P709	This is the color space defined in ITU-R BT.709 for HDTV (1080p/i). If HDR is enabled this should read "DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020" ITU-R BT.2020 is the color space defined for Ultra-High-Definition Television (4K UHDTV)
Monitor Capabilities: HDR Supported (BT2020RGB BT2020YCC Eotf2084Supported )	SMPTE ST 2084 is the industry's reference for High Dynamic Range Video Imaging. SMPTE = Society of Motion Picture and Television Engineers. The 2084 standard defines an electro-optical transfer function (EOTF) with a high luminance range capability.

Dolby Vision typically includes additional (dynamic) metadata streams defined in SMPTE ST.2094-10. This is not supported on Windows Platforms for video playback as Dolby Vision is a largely closed licensed system from Dolby Laboratories for HDR videos and covers the creation, distribution and playback of content.

On Windows platforms only HDR10 with static metadata can be used for HDR video playback. Please check these settings. Set "Auto HDR" to ON as well:

Hello AL_JP,

Thank you for your time.

The issue replication is in progress, we will have the results soon, at the meantime I would like you to complete the following step:

Complete a clean installation with Display Driver Uninstaller (DDU) as you have done before, if you still need guidance follow the article How to Use the Display Driver Uninstaller (DDU) to Uninstall an Intel® Graphics Driver.
We released a new graphics driver the last week, after completing the previous step install the driver version 31.0.101.5081/31.0.101.5122.

Let me know if the issue persists.

Hello Andres,
Is glad to hear form you
I have completed the driver update, please refer to the SSU.txt for details.

After testing, in my case, I am currently able to send SMPTE ST 2084 standard HDR signals to the display via MPC-BE + MPC Video Renderer but not Dolby Vision.

So this issue has been partially resolved.

According to MUC's previous reply, I understand the limitations of the WINDOWS platform with regards to Dolby Vision, but I am still looking forward to a driver update that will make it possible to send Dolby Vision signals to the display, as I can do this with the NVDIA GTX1080 under the same system software conditions.

Andrew L.

Full Dolby Vision video processing is only supported on systems that feature a hardware decoder. Futhermore the Operating System must provide a protected video path to a Dolby certified playback hardware (display device). Android is the only platform to be capable of the protected part so far. Windows processes media via the DirectX graphics infrastructure. The associated application programming interfaces (API) do not offer the requirements mentioned.

The partial support of Dolby Vision in MPC Video Renderer is such that particular profiles are supported in processing. The prerequisite is a data source with High Efficiency Video Coding (HEVC/H.265), 10-bit color depth. The contained Base Layer is translated via an Dolby defined cross-compatibility matrix so that the output is as HDR10 or Hybrid Log Gamma (HLG). The latter is an HDR transfer function that provides BT.2020 colorimetry without metadata but is primarily suited and used for Digital Video Broadcasting (DVB).

In summary, the MPC Video Renderer can output Dolby Vision source material as HDR10. And only this is output by graphics cards under Windows via the physical layer (PHY) corresponding to SMPTE ST.2084. So one's display device will not display "Dolby Vision" but "only" HDR10.

Hello AL_JP,

Thank you for your patience.

We still working on the reproduction of the issue, we have already tested the issue with HDR, I will provide you with the results soon, we are trying to replicate it as accurately as possible.

Do you use any specific app to enable Dolby Vision? How did you test if it was working or not?

Hello AL_JP,

Thank you for your response and clarification.

We want to make sure that we will replicate the issue as accurately as possible, please provide with step-by-step instructions on how to replicate the Dolby Vision issue including download of the software you mentioned on the image, and the necessary updates I have to install, if you can take a video that will be great to have a visual guide.
