Okay, let’s talk about how to solve this problem. Make sure you follow the steps we’ve laid out, and we promise you’ll be back up and running in no time.

Check for Updates

It makes sense to start checking for updates, as Microsoft is committed to releasing regular updates for its Surface range. To check for the latest Windows updates, go to Settings -> Updates and Security and then select the Check for Updates option. If you’re lucky, you might even find a new update for Intel itself, since major components come from that company.

Now, if you’re more interested in updating your video card driver, go to the Device Manager and check from there. Just click on Cortana, type Device Manager Options in the search box, and then click on the option if it’s available. You can also visit the Intel website to manually download the latest Intel graphics driver.

Did the problem occur after the Windows 10 update? Let’s go back.

Launch the Settings app by clicking Windows + I, then choose Updates and Security > Windows Update. From there, go to Update History -> Remove Updates. Find the last update you installed and simply delete it.

Then restart your computer and make sure everything is working properly again. If the problem occurred after the feature update, consider fixing it.

Is Adaptive Brightness on? Turn off

When it comes to saving energy, this is where adaptive brightness comes in. For those who don’t know: Adaptive Brightness is designed to scan the room and the environment looking for a certain level of light. Depending on what it detects, the system automatically changes the brightness of the screen.

This has long been a popular feature on smartphones, and guess what: It works, but there are times when it doesn’t work. To disable Adaptive Brightness, start Cortana and search for Power Options. When it appears in the search query, click Power Options, then select your power plan, and finally click Change Plan Settings.

The next step is to go to Edit Advanced Power Options, and then View -> Enable Adaptive Brightness. From there, change Connect and Disconnect Battery, and you’re done. Click OK, restart your computer, and continue.

Disabling Adaptive Contrast

Since Microsoft doesn’t provide a way to disable adaptive contrast in Windows 10, the most direct way to do so is to use the registry.

Caution: Changing the system registry can have serious consequences if not followed precisely, including driver crashes, system instability, or the inability to start Windows. Users are always advised to back up the system before making registry changes.

Fortunately, changing the registry to disable adaptive brightness is just a key with a number change.
The trick, however, is to find it. And here’s how it works:

  1. On the home screen, look for regedit.
  2. Right-click on it and click or click Run as administrator in application management.
  3. Navigate to ComputerHKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4d36e968-e325-11ce-bfc1-08002be10318}1
  4. Scroll to the middle of the page, then find FeatureTestControl and double-click it to change the DWORD value.
  5. Change the data from 9240 (the default) to 9250 (leave it in hexadecimal).
  6. Click OK to save the changes.
  7. Restart the Surface Pro or Surface Book to activate the change.

This register change effectively kills adaptive contrast and, as far as we know, has no adverse effects.
To reactivate the feature, simply go back to the steps above and change 9250 to 9240, save and restart.

Some users have found that this setting is reset to the default value (9240) every time they perform a major Windows update, so you may need to repeat this change once or twice a year.

Frequently Asked Questions

You are correct that this problem may be caused by the power-saving feature of the Intel graphics chip. This feature, called Intel Display Power Saving Technology (DPST), saves energy by adjusting the brightness of the display according to how dark or bright the content is.

Another feature, similar to adaptive, can cause the Surface Pro 4's screen brightness to dim. This feature is Intel's Display Power Saving Technology (DPST), which adjusts screen brightness based on the darkness or brightness of content on the screen.

The screen should darken slowly and evenly and change the contrast. While adaptive brightness can easily be turned off under Settings -> System -> Display -> Automatically change brightness when light conditions change, unfortunately, there is no easy way to disable adaptive contrast.

Under Power Options, click Change Plan Options, then click Change Advanced Power Options. In that window, scroll down to "View", then click "+" to expand that drop-down menu. Expand the Display Brightness menu, then manually adjust the brightness.
