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

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

Is this a new computer?

When did you purchase it?

Was the HDr feature working fine before on this specific machine?

If so, 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":

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

Since you are trying to use the HDR feature for the first time, it is important first to confirm how to enable HDR and also if the computer complies with the system requirements to use it. In the following link, you will find important details about that matter where you can verify that information including the resolutions supported. Even though it is related to a different Intel® graphics controller, it also applies to newer generations:

https://www.intel.com/content/www/us/en/support/articles/000032112/graphics/graphics-for-7th-generation-intel-processors.html

In that same link, you will find a PDF presentation also including additional facts about HDR. Just in case, here is the link:

https://www.intel.com/content/dam/support/us/en/documents/graphics/HDR_Intel_Graphics_TechWhitePaper.pdf

One of the main things to check is the type of port being used, as you can see in the link, not all of the HDMI versions are supported, it is required for that port to be HDMI2.0a and the DisplayPort needs to support HDCP2.2. 

You can always confirm those specifications on your computer by getting in contact directly with Lenovo Support since that information is not shown in the specifications provided by Lenovo:

Once you do that, if the machine complies with all the requirements and still Windows is lagging while trying the use HDR, please confirm with them if the BIOS version currently installed is the latest one and also you can try to install their latest graphics driver, which is version 30.0.101.1122, that was tested an validated and contains all their customizations to meet the functionality advertised to it:
