Washed out colors on DVI monitor with NUC8i5BEK

[darkf3d3]

If I uninstall video card driver, color are perfect and I would continue to use it without a driver, the problem it's that after few days the driver are installed automatically again.

Using a DVI monitor means you are using an adapter, which is not supported. Connect to a monitor using hdmi or DP, and see if the problem still occurs.

The monitor has only DVI and VGA.

And, your NUC has neither. So, who is wrong?

Test with a better monitor that has HDMI or DP.

What version of graphics driver package do you have installed (look in Apps & Features, not Device Manager)?

Latest for this NUC's graphics engine is 26.20.100.7985, download from here: https://downloadcenter.intel.com/download/29465.

It seem to be something related to most recent driver, because after I uninstall the graphics divers the system automatically reinstall them, version: 10.0.18262.1.

And with this old version colors are perfect. While with the last driver I just installed (26.20.100.7985) the colors are washed out and the black it's more like a grey.

The problem it's that it seem that the drivers are automatically updated, because after a while (few days) colors become washed out again.

I read on a website that the problem can be fixed using "Intel HD Graphics Control Panel" and set "Full Range” under "Quantization Range".

Unfortunatelly it seem that this software it's no more available. I found only "Intel Graphics Command Center" but there's no Quantization Range setting.

Grabbing at straws here. Click on the Color tab and try changing the Brightness Enhancement setting from All Colors to RGB and see if that makes a difference.

I tried modifying brightness but I'm unable to obtain correct colors.

Hhmmm, ok, Intel Customer Support will need to look into of/when support for Quantization Range will be available...

Hello darkf3d3,

Thank you for posting on the Intel® communities.

Regarding the behavior described we would like to know if you were able to follow Al.Hill suggestions about testing with a different TV that has HDMI® or DisplayPort™ video inputs and using a straight-through connection with a single cable, for instance, HDMI-to-HDMI. It is worth mentioning that the graphics video outputs in the Intel® NUC Kit NUC8i5BEK are HDMI 2.0a; USB-C (DP1.2).

Also, we do not recommend the use of any kind of adapters. This is because we cannot test all of them, so we cannot guarantee that these are going to work and wrong color or resolution, flickering, low refresh rate, and any other graphics related issues can be observed when using a video cable adapters, a splitter and/or a docking station. For more information, please refer to this link.

We understand that the colors are better with an old driver "10.0.18262.1" which seems to be the Microsoft® Basic Display Adapter Driver, and you tried to adjust some settings from Intel® Graphics Command Center and also found suggestions about trying with Quantization Range Option in Intel® Graphics Control Panel.

We would like to inform you that the Intel® Graphics Control Panel is still available for new DCH drivers and it can be downloaded from Microsoft® Store*, however, with the most recent drivers (xx.xx.100.xxxx and newer) this option will only be visible if the video output on your computer is native HDMI and using video adapters will cause the option to disappear from the Intel® Graphics Control Panel.

Having said that, we kindly recommend you (if possible) testing straight-through connection HDMI® to HDMI® or USB-C to DisplayPort™ to see if the behavior is different. If the issue persists, please kindly provide the following information:

1- TV brand and model:

2- How are you connecting the TV and cable type:

3- Report for Intel® Graphics Drivers following the steps on the below link:

https://www.intel.com/content/www/us/en/support/articles/000005848/graphics-drivers.html

Note: If using Intel® Graphics Command Center, please launch the application and refer to the Support tab at the left side >> System Diagnostic >> click on Generate Report.

4- Intel® System Support Utility (Intel® SSU) report:

4.1- Download the Intel® SSU and save the application on your computer.

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

4.2- Open the application and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".

4.3- To save your scan, click Next and click Save.

4.4- To attach a file, you must click the “Attach” option on the bottom left-hand corner of the response box.
