Correct Monitor INF file / Adaptive Brightness Settings?

2021-05-29, 13:37 PM

In order to get back adaptive brightness after installing Windows 10 Pro x64 20H2 on my X230T, I am checking the corresponding drivers.

I plan to upgrade my Intel HD Graphics 4000 driver from V10.18.10.4252 from 2015-07-10 to V10.18.10.4425 from 2016-06-29 as recommended by the support page for my machine. The same support page recommends the Monitor INF file V5.07 from 2015-07-13.  However, Windows shows that I already have a monitor driver V6.14.8.0 from 2021-03-29, provided by Lenovo.  Why does the support page suggest an older driver?  Should I really downgrade my monitor driver?

 

P.S. Upgrading the video driver gave me options to control "Display Power Saving Technology" under "Power" on the "Intel HD Graphics Control Panel", but only "On Battery".  However, ISTR having an option under Windows 8.1 for the display to adapt its brightness to the ambient light level. I still find no such option, either in the "Intel HD Graphics Control Panel" under "Display" or in the Windows 10 "Display" settings.  Is my memory an illusion of wishful thinking? Is there a way to get the built-in screen to adapt to ambient light levels?  If so, how?

Hello rsbrux,

 


Greetings

 

 

When was the last time the machine worked with adaptive brightness? And what was the OS build?
Possible reason you're having this issue is because the X230T isn't included in the Lenovo devices tested list for Windows 10 build 20H2.
Update us soon as convenient.

Sorry, I can't provide a build number; I'm not sure I ever had it working under Windows 10. IIRC, it used to work under Windows 8.1

I don't think the monitor inf file contains anything related to adaptive brightness.  Adaptive brightness uses an ambient light sensor.
