Nvidia pannel controls not applying - L340-15IRH

2021-02-22, 13:25 PM

Hello Lenovo community,

 

I am the happy owner of this Ideapad but I run into a bad issue as the title say.

 

I can't change contrast through Nvidia Control Pannel : I check the "use Nvidia parameters" box, change things like contrast'n stuff and as soon as I click somewhere outside the Control Pannel the screen go back to its previous config.

 

GTX 1650, driver : 27.21.14.5167 (windows says me it's uptodate)

Nvidia Pannel : V. 8.1.960.0

Went to the Lenovo support and detected my laptop etc, everything is uptodate except "Intel Management Engine Interface Driver - 10" but it's optional and I don't know if it's somehow useful.

Also went on the Lenovo Vantage because I thought it could take the step on Nvidia put found nothing.

 

Any idea what could do that ?

 

Thank you kindly.

Hello @Issachar,

 

Thanks for reaching out.

 

I would recommend accessing the BIOS then try and turn off switchable graphics then try to set the options again.

How to access the BIOS: https://support.lenovo.com/us/en/solutions/ht500216-recommended-way-to-enter-bios-ideapad

Hello, thank you for your answer. I don't have this option in the BIOS because there is one GC installed (I least I guess, but I saw nothing related to this in BIOS and my Device Manager shows only GTX 1650)

Hello @Issachar,


Thanks for writing back.

 

The option should be available in the configuration tab under the graphic device option.

 

Hope this helps,
Jack_Lenovo1
