How to fix brightness constantly changing after returning from sleep on Windows?

Issue: Hello, I have a pretty annoying issue to deal with. Every time I leave my Surface Pro 6 for awhile (I usually don't turn it off when going to bed) and turn it on later, the brightness changes drastically – it seems like it has been set to the maximum. However, when I check the brightness settings, it is set to what I set it to be. The only way to fix this is by scrolling the brightness control bar left or right. Any idea on what is going on?

Solved Answer

Many users have complained that brightness control was not working in Windows as expected. This issue affected the Surface Pro/Surface Go users mostly (although complaints were also seen from Lenovo community), as they said that the brightness is constantly changing after the device wakes up from sleep or hibernation.[1] In other cases, people reported that the screen becomes incredibly dim after waking up from sleep.

Surface Pro is a touchscreen-based 2-in-1 device that can transform from a laptop into a tablet easily. This feature was generally met positively, as all the available 128GB versions of the initial devices were sold on the launch day. However, these $900 million worth of Surface RT were written off due to a failure.[2]

That being said, many still use the device, although it still manages to cause problems to some people, and inaccurate brightness settings are something that users had to deal with for a while. Do not worry, as the fix is on the way.

One of the main reasons for the brightness constantly changing on Windows is the adaptive brightness setting. Originally it is meant to dim the screen when it is dark and brighten it when there is too much light in the environment, helping people to reduce stress on their eyes while working.

Unfortunately, this function sometimes fails, so you should try turning adaptive brightness on or off in order to fix unwanted brightness changes when the computer wakes up from sleep.

Surface Pro devices use Intel UHD Graphics that need to be installed upon purchase. In many cases, users who suffered from brightness issues were using the default display driver provided with a Windows update. To install the driver, you should visit the official Intel website and download the appropriate one for your device.

If you have Intel drivers already installed on Surface Pro, you should update them. You can do it via the Device Manager, although keep in mind that it can often fail to detect the newest drivers available:

  • Right-click on Start and pick Device Manager
  • Expand the Display Adapters section
  • Right-click on your Intel driver and select Update driver
  • Pick Search automatically for drivers and wait Update drivers
  • Restart your computer once finished.

Instead of digging through the Intel site while trying to find out the relevant driver for you, you could instead rely on an automatic driver updater such as DriverFix. It can backup your drivers and find the latest drivers for you in just a few minutes.

Note: some users said that installing Nvidia DCH drivers helped them to fix changing brightness issue on Surface Pro devices

Fix 5. Roll back video drivers

Reverting to previous driver version is usually not a good idea, although it might be necessary when malfunctions are encountered.

  • Open Device Manager and expand Display Adapters once again
  • Right-click on the display driver and select Properties
  • Go to Driver tab
  • Here, select Roll Back Driver option Roll back drivers
  • Restart your device.
