Windows 10: Screen brightness cycle appearing and dissapearing at different times of the day.

Hello,


I find the feature of cycling through brightness by 25% increments on Windows 10 very useful. But that button periodically dissapears and is replaced with "brightness" button that does nothing when I click on it:





I can't figure out what the problem is. It used to disappear in the mornings, now it disappeared in the evening, there is no obvious pattern to it. Does anyone have any ideas?

:)

 

screen brightness on windows 10

Hi,

Some computers can let Windows automatically adjust screen brightness based on the current lighting conditions.

To manually adjust the screen brightness, we suggest following these troubleshooting steps:

• Click Start, then select Settings.
• Choose System, then select Display.
• Under Brightness and color, move the Change brightness slider to adjust the brightness.

Feel free to post back if you have other concern.

 

Weird issue with screen brightness, no longer changeable


Hello,

Having a weird issue with screen brightness... please help!

It started about 3 weeks ago. I booted into windows and the screen was very dark. I opened the action center and it said brightness was set at 75% - as usual. Clicking on it changed the number, (i.e. it cycles through the brightness settings of 0%/25%/50%/75%100%) however the actual screen brightness did not change.

I've checked everything I could think of, especially in the power management options. Adaptive brightness is off.

So I uninstalled the display adapter driver and restarted - windows automatically reinstalled the driver and everything was fine. A few days later, (including several full shutdowns) it happened again.

In the last 3 weeks it's happened about 6 times. Each time, I reinstall the display driver and it works fine a few more days.

Interestingly, of the 6 times it happened, 1 was a bit different. Instead of the screen being very dark, it was very bright, as if i'd set the brightness to 100%. Otherwise it was the same - i.e. I couldn't change the screen brightness (although again, I could cycle through 0%/25%/50%/75%100% in the action centre).

I was hoping that a windows update would fix this issue, but I received an update a few days ago and the problems persists.

Any help/ideas would be very much appreciated.
