Intel UHD Graphics on i9-11980HK dropping resolution problem

[DrDEAD]

I've got a problem with Lenovo Legion 7, Intel i9-11980HK and Nvidia RTX 3080 (16GB - not 4GB like you detect it). Intel UHD grafics not work correctly with swichable grafix ON (Optimus Mode). My laptop screen native resolution is 2560x1600 165Hz, but when a game start to use Nvidia's card, Intel's card resolution drops a lot (for Background aps, Desktop etc.), don't know how many, and settings show like i use second monitor, but i use laptop screen only! When I switch to "Descreet Mode" in the BIOS/EFI (Intel UHD - is OFF) and resolution don't change (Drop) any more. I hope for a FIX. Cheers and Happy Holydays.

DrDEAD, 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:

Is this a new computer?

When did you purchase it?

Were you seeing this resolution problem with the Intel® graphics on this same machine before?

When did the issue start?

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

Which Windows* version are you using?

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":

I was stupid.. Lenovo automatic drivers instalation program don't install chipset drivers.. I download and instal them manualy and all is good. Thanks.

[DrDEAD]

Yes it's a new laptop and I'm a little excited. 😂

[DrDEAD]

.. btw Intel Driver & Support Assistant don't install them too. That's why I was confused. I get them from Lenovo site .. Happy Holydays ..

[DrDEAD]

Grrr .. still got the same problems .. 

OK, here we go:

Is this a new computer?

- Yes

When did you purchase it?

- 15-18.12.2021

Were you seeing this resolution problem with the Intel® graphics on this same machine before?

- It's a New machine, New Windows 10 Pro..

When did the issue start?

 - When playing games that use the other grarhic card - Nvidia RTX 3080 16GB ..  (In Auto mode, and in Nvidia Only Mode)

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

 - Don't think so, a new laptop with new windows ..

Which Windows* version are you using?

 - Windows 10 Pro

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

 - Home and Work

Only solution I find so far is to change in BIOS to use Nvidia only. 

P.S. Nvidia graphics card is with 16GB. You recognise it with 4GB. I made a second report after some tests with Lenovo diagnostics.

P.P.S. Optimus Mode is Intel graphics only..

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

Based on the details shown in the SSU document, we can confirm that the graphics driver version currently installed on your computer is 27.20.100.9365.

Just to let you know, we always recommend to install the graphics driver provided by the manufacturer of the computer, since that driver was customized by them to work with your specific platform.

I looked on Lenovo's website and the latest graphics driver version they have available is 27.20.100.9749. Please try a clean installation of that driver following the instructions in the links below:

https://pcsupport.lenovo.com/mo/en/products/laptops-and-netbooks/legion-series/legion-7-16ithg6/downloads/driver-list/component?name=Graphics%20Processing%20Units%20%28GPU%29%20and%20Server-AI%20Accelerators

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

If the problem persists after that, even though the Intel® graphics drivers are generic and they might not work properly with your system since they do not contain the customizations done by Lenovo, for testing purposes we can try a clean installation this time of the latest Intel® graphics driver version 30.0.101.1191:

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

We also advise to get in contact directly with Lenovo Support to make sure the latest BIOS version is currently installed on the machine or to gather the instructions on how to do that:

Thanks for the advice. I didn't know that the drivers could be modified for the product. I reinstalled all of them from the Lenovo website and it is now more stable. There are some things that need more optimization and I hope to be done in the future as in this build after launching the Nvidia graphics card (launching а game ) all processes that can use graphics are loaded on this card and after exiting the game it returns to Optimus mode (Intel Grapfics), but the processes remain for execution by Nvidia. They do not return to Intel graphics.

At least the problem with the resolution is solved. 🙂

DrDEAD, You are very welcome, thank you very much for providing those results.

"At least the problem with the resolution is solved. ", perfect, excellent, it is great to hear that the problem with the resolution got fixed after installing the graphics drivers provided by Lenovo and now the system is working properly.

"There are some things that need more optimization and I hope to be done in the future as in this build after launching the Nvidia graphics card (launching а game ) all processes that can use graphics are loaded on this card and after exiting the game it returns to Optimus mode (Intel Grapfics), but the processes remain for execution by Nvidia. They do not return to Intel graphics.", In that case, what we suggest in this situation will be to get in contact directly with Lenovo support to report this scenario and provide your feedback on this matter, since everything on a mobile device such as a laptop is customized by the manufacturer of it, that way they will be aware of your remarks to take them into consideration for future releases:
