XPS 13-9370, Disable Dynamic Brightness Control?

I have found a fix and drivers / updates for previous versions of Dell XPS - but for the 9370 there is no Dynamic Brightness Control fix - and an option to Disable.  How can I enable / disable dynamic brightness ? Is it built into the settings anywhere or do I have to wait for Dell to release a fix for this as well?

The fix for 9360 is right here: https://www.dell.com/community/Laptops-General/XPS-13-9360-vs-Dynamic-Contrast-Brightness/td-p/51486...

BUT I need this for the 9370 - please HELP!

Thanks!

FIX FOUND

After consulting a few colleagues at work I have found the fix - that no one mentions in any post online.

You can go into BIOS settings (hit F2 as you are restarting your computer) - and DISABLE Dynamic Brightness Control in the display options. I don't know if you need to update the laptop to the LATEST bios to have this option (I did the update).

Hope this helps someone and avoids tons of aggravation of constant screen color flickering.

Thank you so much Dell_Guy ! It was driving me crazy...

When I went into BIOS settings, the option was called "Dynamic Backlight Control" located under the "Video" section.

I also found this thread (more recent), which deals with the same issue : https://www.dell.com/community/XPS/XPS-9370-13-quot-HD-screen-colour-tone-problem/td-p/6032522

And Tobias0815 gave a useful tool to check if the screen is affected by "dynamic brightness" or not : http://tylerwatt12.com/dc/

In the current latest BIOS (1.8.1) the Dynamic Brightness Control seems to be removed or I couldn't find it.

Can someone else confirm? If this is true, I'm glad I stayed on 1.6.3.

I have 1.8.1, and have the Dynamic Backlight Control under the Video settings link.

I suppose the next question is whether Dynamic Backlight Control is still present in BIOS version 1.9.0, which is the current version. I may take a chance anyway since the current BIOS is intended to deal with a security vulnerability identified by Intel.

I just updated the BIOS to 1.9.0, and now I can't boot into the BIOS at all. I've tried several times by holding down F2 during the boot sequence, and the computer just boots into Windows.

OK. I got into the BIOS, but I had to do it through Windows Recovery which offers an option to access the BIOS (UEFI). When booting using the previous BIOS, Dell had a brief statement during the boot sequence which tells you to press F2 to boot into the BIOS. This statement is no longer present in version 1.9.0. So it seems you must do this through Windows now. I'm going to make a separate post about the steps to follow.

If someone is running version 1.9.0 and still has the F2 option, I'd be interested in hearing about that.

P.S. The setting to disable Dynamic Backlight Control is still present in 1.9.0.
