Bad colors on my NUCs

[Kruis]

Hi all,

I have 2 NUCs, a 10i3FNX and a 11PAHi7, both updated to the latest available versions of BIOS and drivers.

Both are connected via HDMI to 2 different TVs, one is a modern 4K Samsung, the second one is a Full HD Sony, so it's not a display issue.

Both have the same problem ever since I bought them.

The problem is that I see wrong colors. Less sharp, less brilliant. For example, I don't see the Windows 10 taskbar black, but dark gray.

I also noticed that during driver updates, to be precise just after rebooting after uninstalling the previous drivers, I see the right colors (perfect blacks, vivid colors).

As soon as the new driver is installed, they go back to being wrong.

There's a way to solve this issue?

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

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

Are those new Intel® NUCs?

When did you purchase them? (For Warranty Purposes)

What is the model of the monitors?

4K Samsung:

Full HD Sony:

Are you using adapters or converters to connect the screen to the Intel® NUCs?

Did you make any recent hardware/software changes, besides updating the drivers that might cause this issue?

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

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

Hi @Alberto_R_Intel ,

it's definitely not a hardware problem.

Both units are no longer new now, but this problem, identical on both, arises from the moment of purchase.
I bought the NUC10i3 in an Italian online store, while the NUC11PAHi7 on Amazon.

4K Samsung: it's a TU8000 serie, a Samsung S8 43"

Full HD Sony: it is a old Sony Bravia 38" LCD TV,  I don't remember exactly the model.

Both units are connected to the relative display only with the HDMI HQ cable, without adapters or filters.

But in both cases, the issue is not caused by displays, because, as I wrote, if I uninstall the GPU drivers, colors are good, for both my units.

I have not make any relevant change, but as I have wrote, the issue has always existed, despite the constant updates of divers to the most recent versions.

The problem happens always It is not temporarily.

You can find the SSU log attached.

Thank you for help,

Cris

Hi Kruis, Thank you very much for providing that information and the SSU report.

Based on the information shown in the SSU document, the BIOS version installed in your Intel® NUC is 0046, which is the latest one:

https://www.intel.com/content/www/us/en/download/19694/bios-update-patgl357.html?wapkw=nuc11pahi7

And also, the graphics driver version currently installed is 31.0.101.3222, provided by Intel®:

The Intel® NUC 11 Performance kit - NUC11PAHi7 works with 

Intel® Iris® Xe Graphics, based on that, for testing purposes, please try a clean installation of our latest Intel® graphics driver version 30.0.101.3413, following the instructions in the links below:

https://www.intel.com/content/www/us/en/download/19344/intel-graphics-windows-dch-drivers.html?wapkw=1165g7

Did you test different HDMI cables?

Even though you mentioned that the screens work fine if you uninstall the graphics driver, I looked on Samsung's website and they recommended to update the software on the TV, did you tried that already?

Same thing with the Sony Bravia 38" LCD, they recommend, if available, to install the updates for your specific model:

Hi @Alberto_R_Intel ,

among all the options you have indicated, the only one that seemed plausible to me is that of the HDMI cable, moreover identical for both units.

That was indeed the problem solved.

Thanks for the help and good evening!

Hi Kruis, You are very welcome, thank you very much for sharing those results.

Perfect, it is great to know that the problem got fixed after replacing the HMDI cable and now the Intel® NUC is working properly.
