NU11 supports 10bpc/NU11 mandatory 4:2:2

[asdc199]

Hello there，

My device is NUC11PAKi5.

My monitor is LGCX48, it only has HDMI2.1 input interface.

When i connect to use them,Its image quality is significantly inferior to my previous HDMI2.0 version

I try to turn on 4K, RGB, 120Hz,It ran successfully.

but,HDR does not work properly，The color is very abnormal，Saturation is almost 80% lower.

So, I tried to turn on 10BPC under non-HDR conditions to get better colors.Unfortunately, I did not find any options that can be set in the graphics control panel like NVIDA.I checked the information，Understand that the HDMI2.1 interface of NUC11 is realized by the transfer solution，It is guessed that this is the reason why there is no 10bpc option in the XE graphics control panel.

now, How should I make HDR work properly？Or turn on 10bpc under non-HDR conditions to get better colors?

（Sorry, I am not good at English, the above text comes from Google Translate）

PS.My graphics card driver has been updated to the latest version.

     My system version is Windows 10 20H2.（I also tried the latest windows 11）

Hello asdc199, 

From the report We noticed that you are currently using Windows 11, since this new version of Windows is not fully compatible with all our devices in order to continue further I will appreciate it if you roll back to Windows 10 and provide the following:

1. Repor from the Intel® System Support Utility with Windows 10.

2. Take pictures of the issue (besides the ones that you provided).

hi，Deivid A.

Since I only have one working PC, I can't roll back to Windows 10.（I had the same problem with Windows 10，Also, we know that both of them use the same kernel, just the UI improvements）

I have all the HDR related options turned on，All options that can be set are set，It's still not working properly。

I've already turned on the HDR Settings

[asdc199]

In addition,

I noticed that Intel has released a Windows 11-compatible graphics driver, version number: 30.0.100.9684.

Problems persist after installation .

30.0.100.9684

Hello asdc199, 

Thanks for the information provided.

I will proceed to check this further, however, bear in mind that Windows 11 is not officially released yet and even if we released a new driver you may need to check this issue with Microsoft.

As soon as I have any updates, I will let you know.

Hello asdc199, 

Bear in mind that Intel official OS is reported here https://www.intel.com/content/www/us/en/support/articles/000005628/intel-nuc.html

If this problem was present in Windows 10, then we need the appropriate reports to start debugging the issue. To continue further, we will require running a supported operating system in the NUC.

I am sorry that each other is entangled in the problems of windows11，If Intel has a NUC11, it can test for related problems.

I have used windows10 for about three days ，tried all the settings,  it is not working properly . 

even so，I will run windows10 on NUC11，So that you can debug the problem, Sit tight, please.

Hello asdc199, 

Thanks for the update.

Just as a friendly reminder, we currently support only up to Windows 10 because Windows 11 has not been officially released. In addition, I would really appreciate it if you can provide the report and the information requested under Windows 10.

hi,

Deivid A.  

Today I reinstalled my system and now my NUC11 is running windows10, the color of HDR is incorrect ， the 10bpc option does not appear in the graphics card control panel.

I have attached the report, hoping it will be helpful to your work

[DeividA_Intel]

Hi @asdc199 

I am checking with the Product Team, let me find out and I will get back to you as soon as possible.

Regards,

Ronny G

[asdc199]

ok, I await your response.

[Ronny_G_Intel]

Hi @asdc199 

Unfortunately no good news, the official maximum resolution supported is 7680X4320@60Hz with DSC or titled screen, I would say that in a standard configuration we support 4K@60Hz , and currently, we don't have a way to manually set up the Chroma Subsampling.

There Intel® Graphics Command Center (IGCC) team is working on adding this functionality so I would recommend that you keep on checking for the latest version available.

Official support:

I hope this helps.

hi,Deivid A.  

Thanks for your answer.I feel frustrated.I will keep an eye on the latest version.Any news about the issue of HDR color?

[DeividA_Intel]

Hello asdc199, 

I would like to let you know that the issue with the color on "HDR" was related to the fact that you were trying to run 4K at 120Hz when it supports up to 60Hz. 

As mentioned by Ronny_G_Intel, I recommend you to keep an eye on the Intel® Graphics Command Center (IGCC) for any updates.

If you have another question, do not hesitate to let me know.

Best regards, 

Deivid A.

hi,Deivid A.  

In fact, the color problem of HDR also exists at 60hz or 30hz.

As long as the INTEL technicians have done a test, you can easily find this problem. Note that what I said is not a normal color for SDR content, but it is a color fade problem for HDR content.

Now, I bought appletv 4k, its HDR color is normal, if you have any other equipment, you can find the problem with NUC11.
