No option to adjust brightness

Hello Maricris,

There are certain factors that might cause this concern. It is possible to be driver related.

For this concern we recommend that you update your graphics card's driver. You can check with your graphics card manufacturer's website for assistance.

Also check your monitor's setup on Device Manager:

• Press Ctrl and X.
• Select Device Manager.
• On the list of devices, expand Monitors.
• Right-click on Generic PnP Monitor.
• Select enable.

Do not hesitate to reply on this thread if you need further help.

 

No option to adjust brightness

no brightness adjusment? please help

 

...............When i went into display settings there was no slider or option to change the brightness setting.....................

Yes, there is. However, one member says the setting does not stick. Meaning you need to set it again next time after restart.

Settings > System > Display > right side, under Orientation, change it to Portrait > the Apply and Cancel buttons are now active > change Orientation back to Landscape > move the slider to the left to reduce brightness > click Apply when done.

 

Are you using a laptop ?
If yes, do you have 2 keys in your keyboard from which you can adjust Brightness ?
Mine has. What I do is press the FN key and HOLD > then press one of the brightness keys to adjust.

About Fn keys I wanted to report that current Windows 10 10586.164 has some problems with some laptops...
To be exact the Fn keys for brightness may not work (on screen slider moves but without visible effects).
I've reproduced this issue on my laptops MSI GX660 (AMD GPU + drivers) and Samsung Ativ Book 2 NP270E5V-K05IT (Intel IGP + drivers).

To fix this problem you have to:
1. open Regedit and go to key "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000"
2. change "ApplyNativeMode" to 1 (from 0) on Samsung + Intel drivers; on MSI + AMD Crimson drivers look for "KMD_EnableBrightnessInterface2" and set its value to 0
Log-out and re-login or reboot.
