UHD Graphics 630 brightness not working

[Amir_96]

Good morning,

suddenly my computer's brightness stopped working, I had windows 10 I tried to uninstall the drivers with the guru3d driver uninstaller tool and do a fresh install but it didn't work.

I tried using the standard Windows driver but the ability to manage the brightness disappears from settings.

I updated the Bios at the last version and installed Windows 11, I installed the new drivers but the problem is still present.

My setup:

CPU Intel® Core™ i7-10700 8 core (2,9 GHz) 16 MB cache

Motherboard ASUS® H410T: (Mini-ITX, DDR4, USB 3.2, 6 Gb/s)

Driver from ASUS web site:

Intel VGA driver V30.0.100.9864 For Windows 11 64-bit.

Versione 30.0.100.9864

552.31 MB

2021/10/22

I tried also the Intel Driver & Support Assistant Tool without success.

Can you help me to resolve my issue?

Thank You

Hi Amir_96,

Thank you for posting in Intel Communities.

Could you please elaborate on the problem you're encountering? Is the issue that you're unable to modify your system's brightness using the slider in the Display settings, or is the brightness slider missing altogether?

Additionally, does your system have a dedicated keyboard shortcut for brightness control, and if so, have you attempted to use it?

Best regards,

Hi Amir,

The latest graphics driver for your CPU is  Intel® Graphics Driver 31.0.101.2128.  Also in Asus site, for you board (H410T) I can see an outdated driver Version 23.20.16.4849.  Any way, download and install the latest driver from Intel site.

Hello,

thanks everyone, speaking with the computer builder I discovered it was a BIOS parameter:

BIOS -> Advanced -> LVDS Configuration -> Was set to "no" and should be set to 1920x1080 LVDS1

Probably the BIOS default values ​​were restored and having also done the update the manufacturer's custom parameters were lost.
