We continue our series of articles about problems in the Surface Pro 4. After solving (or at least trying to solve) waking up problems in our previous article, we move on to another common Surface Pro 4 issue. This time, we’re going to talk about the annoying screen dimming problem on Surface Pro 4, and how to (try to) solve it.
A few things can cause the screen dimming problem with Surface Pro 4, so we’ll cover all of them. If you’re also facing this annoying problem, check our solutions below.
How to fix the screen dimming issue on the Surface Pro 4
Solution 1 – Turn off adaptive brightness
Adaptive brightness is a tricky thing. This feature can be extremely useful, in terms of saving power, but sometimes, it can also be troublesome. In case you don’t know how this feature works, adaptive brightness scans your surroundings and automatically sets your screen brightness based on a level of lightness around you.
As we said, adaptive brightness can go wild sometimes, causing various issues on a device, including the screen dimming problem. So, if you’re facing the screen problem, you should try disabling the adaptive brightness feature, and see if the issue is resolved. Here’s what you need to do to disable adaptive brightness on your Surface Pro 4:
- Go to Search, type power options, and open Power Options
- Next to your selected power plan, tap or click on Change plan settings
- Now, go to Change advanced power settings
- Expand Display > expand Enable adaptive brightness
- Now set both ‘On battery‘ and ‘Plugged in‘ to off
- Click OK.
Once you disable the adaptive brightness feature, the problem with screen dimming on your Surface Pro 4 device will hopefully be solved. However, if the issue is still present after disabling adaptive brightness, try the solution from below.
Solution 2 – Disable Intel graphics features
Another feature that’s similar to adaptive brightness can cause your Surface Pro 4’s screen to dim. That feature is Intel’s Display Power Saving Technology or DPST, that adjusts your screen brightness based on how dark or light the content on screen is. So, adaptive brightness scans your surroundings to adjust brightness, and DPST scans what’s actually on the screen.
Of course, the solution is to turn DPST off, as well, but that won’t be as easy as disabling adaptive brightness. Some older PCs have the option to disable DPST via Intel’s driver configuration software, but unfortunately that software is not available on the Surface line of tablets, so it’s impossible to ‘legitimately’ disable this feature on your Surface Pro 4.
However, there’s an alternative way of doing that, by using one registry tweak. So, if you want to disable Intel Display Power Saving Technology on your Surface Pro 4, here’s what you need to do:
- Go to Search, type regedit, and open Registry Editor
- Go to the following path:
- Now, open the DWORD called FeatureTestControl, and change its value from 9a40 to 9a50
- Restart your computer.
Once you perform this action, Intel’s DPST will be disabled, and potential screen dimming issues will be solved. However, if the FeatureTestControl value is different than 9a40 on your Surface Pro 4, check out this article for a further solution.
Solution 3 – Check for updates, and make sure your drivers are up to date
Microsoft releases new updates for devices from its Surface line quite often. So, there’s a chance that Microsoft or Intel pushed a new update for the Surface Pro 4 before you found this article. Just in case, head over to Settings > Updates & security, and check for updates.
The same thing applies to your Surface Pro 4’s graphics card. Go to the Device manager, and check if a new version of a graphics driver for your device is available.
We also recommend this third-party tool (100% safe and tested by us) to automatically download all the outdated drivers on your PC.
Screen dimming, and other display issues can be very annoying, especially on portable devices like the Surface Pro 4. We hope this article helped you to solve the screen dimming problem on your Surface Pro 4, and if you have some other screen-related problem on your device, check out this article for a potential solution.
