Hi, Victor

Thank you for your answer.

Here is my answer.

  1. Yes, at the time of the purchase of the computer (September 2020) and until the end of November, the HDR option worked flawlessly.
  2. I did not install any new hardware, the software does not change either, with the exception of Windows and driver updates.
  3. The fact is that the same problem arose on the two previous versions of the video card drivers.
  4. I can't say for sure, because for some time I did not turn on the HDR option. Precisely, there was no problem either on the Windows 20H1 version, or on the 20H2 insider build, which is relevant at the end of September 2020 (I, alas, no longer remember the exact build number). Is the issue related to upgrading to build 19042.685? Perhaps, but alas, I cannot answer this question exactly. ☹

Looking forward to your response.

Sincerely yours,

Arthur

Hello Grokh,


Thank you for posting on the Intel® communities.


Please take a look at the following information and let us know if you need anything else.


When it comes to a laptop such as yours and having this type of issue, it is worth mentioning that because the system is an original manufactured one, it comes with a lot of factory customizations that are needed in most scenarios so the system works as it is supposed to; however, we do need to inform you that the drivers that you have been using with it are not customized, they are actually generic versions; therefore, please try to complete a clean installation of the latest OEM(original equipment manufacturer ) customized driver and then test the system with it, if the issue persists please do the same with our latest generic driver and let us know if the issue persists after that.


Clean Installation of Intel® Graphics Drivers in Windows® 10

Note: These instructions work with both the customized driver and the generic one.


Latest Lenovo driver

Note: To find the driver please follow this path Manual Update> Display and Video Graphics> Intel GFX Driver for Windows 10 (64-bit) -Yoga C940-14IIL> Download.


Latest generic driver

Note: If the installation is unsuccessful with the .exe file, try installing the driver using the .zip file

Hi, Victor.

Thank you for your reply. Today it is already midnight, but tomorrow I will try to install the original driver from Lenovo (OEM) "from scratch" and see what happens.
But I must say right away that there was definitely no such problem on Intel drivers of versions 27.20.100.8681 and 27.20.100.8783.
Unfortunately, I can't tell if it appeared with the driver version 27.20.100.8853 or later.

Hello Grokh,


Thank you for posting on the Intel® communities.


Sometimes it is quite unpredictable for us to determine how is an original manufactured system going to work with our drivers, mostly because manufacturers are in charge of using our drivers as a base for their customized versions and do the testing for their systems; however, we appreciate the feedback and the information you have provided and we will be waiting for your outcome.


I look forward to hearing from you.

Hi, Victor.

Yes, I check the post before. Sorry, I have now too much job and cannot find enough time for the experience with the drivers. I will try to change the different driver this weekend.

I apologize for my long silence. Was in the hospital for a major open heart surgery.

 

The problem is solved - on the latest version of the Intel video driver, the HDR mode is enabled / disabled normally, without failures.
