HDMI 2.0 raised black levels when connecting to 4K TV in intel NUC 8i3BEH

Hi,

 

 

I am so dissapointed when I found my beloved Intel Nuc 8i3BEH with Intel Iris Plus 655 Graphics has faulty drivers that does not allow correct black level when paired with a 4K TV with HDMI 2.0 cable.

 

For reference my OS run on Windows 21H2.

 

According to this thread, Solved: Full RGB quantization range over HDMI, with latest drivers - Intel Communities you can download Intel Graphics command center from MS store and change the quantization range input to full to resolve the issue. There is also an input range that can be selected in video menu. I have to set this to none/limited because choosing full will render my display with a persistent grey overlay. 

 

Back to the issue at hand, changing the quantization range to full does nothing. The image generated still does not provide correct black levels/colors. It is an odd issue because I had tried connecting my nuc to an older tv unit and it can display the correct colors. In contrast, I had also tried using my laptop with only hdmi 1.4 port to this TV (the one with issues with NUC) and it also can display correct colors despite only able to output 4K30hz maximum resolution due to bandwith limitation.

 

Using a usb C to HDMI 2.0 adapters also doesn't resolve the issue. I'm at a loss at figuring out any workaround to give me the correct image. The only remaining solution that might work I thought of is if there were a way to download really old drivers that was reported to just work with no glitches. 

Why is this still a problem late in 2022? Please please Intel can you fix my problem I really don't want incapacitated my nuc.

redroof, Thank you for posting in the Intel® Communities Support.


In order for us to provide the most accurate assistance on this scenario, we just wanted to confirm a few details about your system:

What is the model of the TV?

Was this issue with the black levels happening before on this specific Intel® NUC?

If not, when did the issue start?

Did you make any recent hardware/software changes that might cause this problem?

Does the problem happen at home or in the work environment?

Please attach the SSU report so we can verify further details about the components in your platform, check all the options in the report including the one that says "3rd party software logs":

https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-?product=91...


Here you have the "Quantization Range Option in the Intel® Graphics Control Panel or Intel® Graphics Command Center User Guide":

Thank you for noticing this post Mr Alberto R

 

To answer your questions sequentially :

- The Model of my TV is recently bought TCL C835 ( I think it doesn't exist in USA)

-  I wish I knew the correct term for my issue instead of saying this a problem with black levels. But I can say that when I  played some video where the scene is very dark, my NUC displayed more yellowish version of black with more noise/color band, which is why I suspected the input signal is somehow limited even when the setting is full. That said, this issue only appeared when using my new TV. So no, the issue wasn't found on my previous device setup which include an LG Monitor and Samsung TV. But! Using other Windows device like my main PC and notebook running WIndows 10 I had no problem so it is so odd.

- The issue started when pairing NUC with my new TV. I had double check to set the HDMI mode in TV to support HDMI 2.0 and my cable also.

- I had tried clean installing windows 11 from previous attempt and reverting back to Windows 10 via a system image backup when it failed.

 

Here I will attach the SSU report as requested.

Since your Intel® NUC works with Intel® Iris® Plus Graphics 655, for testing purposes, please try a clean installation of our latest graphics driver version which is 31.0.101.2114 following the instructions in the links below:

https://www.intel.com/content/www/us/en/download/19344/intel-graphics-windows-dch-drivers.html?wapkw...

https://www.intel.com/content/www/us/en/support/articles/000057389/graphics.html


The BIOS version on your device is 0089, there is a newer version available, 0090, please install that version using the F7 method, based on the instructions shown below:

Even though the HDMI cable seems to be fine, do you have the option to test another one?


Additionally, sometimes the monitor also has a firmware update available. I was not able to find it, but if you have the opportunity to get in contact directly with TCL support, they should be able to confirm that information:

Once you get the chance, please let us know the results.

Just a heads up,

 

I am quite sure I had tested those option in the past before I reset to a custom restore point and none really work. But let me try again maybe something will change though im quite skeptical. 

I will need some more days to update my BIOS tho because currently I don't have a low sized FAT32 USB lying around. 

Also while I am waiting for my shipment to come, I am actually hesitant to upgrade HDMI firmware because from previous experience this doesn't actually do anything to the displayed settings and there is no option to revert it back to older/default firmware.

As for firmware update, there is currently no firmware update from TCL that I found officially. It's quite sad this TV while very pricey, doesn't really show the option of HDMI enhanced mode or deep color and such. Guess TV is not made for tinkerers *sniffle* or desktop use.

redroof, Thank you very much for sharing those details.


Sure, no problem at all, take your time to do the tests and the updates on your system in order to try to fix this problem.


We completely understand that you are hesitant in doing the HDMI firmware update. Those are just troubleshooting steps that we normally recommend to do in this type of scenario.


Regarding the firmware update of the monitor, we always recommend to contact the manufacturer of the device directly to make sure that option is available from their side.


Once you get the chance, please let us know the results.

Dear Alberto R,

 

So after further testing with updated BIOS, HDMI Firmware tool, and installing the latest GPU drivers, I need to make a confession.

Apparently my video playback issues only occurred when using Kodi as video media player. Using other media players such as MPV showed the video in correct colors or black levels. 

I had tried every possible configuration with Intel Graphics Command Center range and from Kodi itself including putting it to limited range. Sadly I can't access how to choose limited/full range in my TV. That option simply does not exist.

So unfortunately this meant that I am still stuck because something, somewhere along the chain of Kodi>>GPU>>TV reported the wrong information which messed the end result. Still mad because other PC with discrete graphics doesn't have this problem, but I can't point out exactly where the fault may lie. Easiest to blame is the DP to HDMI LPCon used in my NUC possibly can't offer full color range.

Hello redroof, Thank you very much for letting us know those results.


We are sorry to hear the issue persists when using Kodi. Based on that, we will do further research on this matter to verify if there might be a compatibility problem between our driver and Kodi. 


As soon as I get any updates, I will post all the details on this thread.

Dear Alberto R,

 

So I might be an idiot actually. I usually never tinkered with default settings, but during my experimentation to troubleshoot the issue,  I might have inadvertently toggled on post processing effect like contrast enhancement or brightness adjustment in video tab. I disabled most video processing and now it looked like it was fixed. So I am sorry if I wasted your precious time.

 

But, I am still not sure if I did it right tho for most accurate video representation? Because I am quite sure default values shouldn't have any trouble in the first place. Can you check and list or attach a screenshot of the default values used in video tab from IGCC? (which effect(s) was used by default?)

 

Also, how do I confirm if the GPU to TV connection is outputing full range? In the latest video driver, choosing between default, limited, and full produces no change in color/brightnesss/gamma when it should be more readily apparent so tbh im simply not sure. Maybe I just have to accept those values as truth instead of nitpicking...

Hi redroof, Thank you very much for letting us know those updates.


No problem at all. It is great to know that after selecting the proper settings the graphics problem got fixed.


The suggestion for the previous issue was to get in contact directly with Kodi support since the issue was directly related to their tool. Based on the fact that the problem does not happen with other applications, we can rule out an Intel® driver issue in this scenario.


In reference to your new requests, I will double-check if we can provide additional details on that topic. As soon as I get any information, I will post all the updates on this thread.

Hello redroof, I just received an update on this matter.


In order to make sure that the default settings for the Intel® GCC application are being used, try a clean installation of the tool:

Thank you for your help. I can confirm uninstalling IGCC and reinstalling it from Windows 10 Store has reverted the values back to default. As for if it fixed my issue(s), hopefully it fixed them honestly its hard to say.

I updated Windows yesterday, and when I reinstall IGCC it seemed to revert my igpu driver back to version 27. I had to manually did the re-update GPU drivers to latest version all over again via the 1GB+ driver in the link provided above. Guess I have to accept my NUC as it is if I can't make head or tails about this hahah

redroof, You are very welcome, thank you very much for providing those outcomes and the pictures.


Perfect, it is great to know that the Intel® Graphics Command Center has reverted the values back to default after a clean installation of the tool.


In reference to the previous issues, what we recommend is to get in contact directly with Kodi support since the issue was directly related to their tool, taking into consideration that the problem does not happen with other applications, we can rule out an Intel® driver issue in this scenario:
