how to disable "intel display power saving technology"

Question

I'm using a Dell Vostro 5490 running Windows 10. Under "display adapters," for me it says

Intel(R) UHD Graphics 
NVIDIA GeForce MX250

I tried disabling the Intel Display Power Saving Technology, because the automatic foreground/background screen brightness adjustment is annoying. But I can't seem to find the option listed on most guides. There is no Display Power Saving Technology checkbox. There isn't even an Enable adaptive brightness setting in my power options.

Answer 1

Method 1 : Disable Adaptive brightness in the Registry

• start regedit
• Navigate to
  HKEY_LOCAL_MACHINE\SOFTWARE\Intel\Display\igfxcui\profiles\Media\Brighten Movie
• Double-click on ProcAmpBrightness, set to 0 and click OK
• Navigate to
  HKEY_LOCAL_MACHINE\SOFTWARE\Intel\Display\igfxcui\profiles\Media\Darken Movie
• Double-click on ProcAmpBrightness, set to 0 and click OK
• Exit regedit and reboot

Method 2 : Disable Intel display power saving technology

Disabling Intel display power saving technology is complicated by the fact that the Intel Graphics Control Panel no longer shows the option for disabling it. Registry work is now required for that:

• Launch regedit
• Navigate to
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0001
• Find FeatureTestControl, double-click it and copy its value to the clipboard (mine is 8280)
• Open the Calculator, set it to Programmer mode, click HEX, then paste the value
• Click BIN (mine: 1000001010000000)
• Change the 5th bit from the end to 1 (mine: 1000001010010000)
• Click again on HEX and copy to the clipboard (Ctrl-C)
• Set FeatureTestControl to this value
• Reboot

A PowerShell package that does all these manipulations can be found in Github dpst-control. After unzipping, you may use its scripts, named appropriately get-status.bat, disable-dpst.bat and enable-dpst.bat.

Method 3 : Run Power troubleshooter

• Run Settings > Update & Security > Troubleshoot
• Click Power > Run the troubleshooter

Answer 2

Refer to Method 2 of harrymc's answer, you can always disable the Intel Display Power Saving Technology or Adaptive Brightness Settings by turning off the Display Power Savings Options.

However, the problem is Intel does not save this setting changed by the user and the Display Power Savings Options will be automatically enabled everytime you reboot. After you follow Method 2, open Intel Graphics Command Center again and the Display Power Savings option should disappear. This works for my Lenovo laptop which has two graphics card.

Note that you have only 1 graphics card, then your FeatureTestControl will be in \0000 subkey. If you have 2 graphics card like mine, then your FeatureTestControl might be in \0000 or \0001 subkey. You can check your DriverDesc in both subkeys and I assume that the FeatureTestControl will only appear in the subkey in which the DriverDesc is an Intel Graphics Card.

There's a GitHub repository (orev/dpst-control) that allows you to easily enable or disable Display Power Saving Technology by running a script file.

1. Clone the repo: git clone https://github.com/orev/dpst-control.git
2. Open the repo root directory in File Explorer
3. Right click on disable-dpst.bat and click "Run as Administrator" to disable DPST (or enable-dpst.bat to enable)
4. Reboot your computer

For your reference, this script file works on my Surface Pro 6 with Windows 10 version 20H2 (October 2020 update).

Answer 4

I was facing the same problem and after a long search discovered that the function is taken on by the 'EcoPower' function in the Dell BIOS (at least on my Dell XPS 13).

Boot into Dell BIOS Setup, go to Video > Eco Power > Enable EcoPower > OFF

Answer 5

Display Power Saving Technology can be turned off in Intel UHD Control Panel (driver ver. 26.20.100.7810), but to my dismay, it turns itself on relentlessly whenever I reboot. Lenovo ThinkPad 590. Registry: FeatureTestControl exists only in the \0000 subkey, not in \0001. Just search for it globally. Changing it there seems to have helped.

Answer 6

If you have the Intel-based graphic in your notebook, you need to use Intel® Graphics Control Panel.

Run the Control panel and click on the Power section at the bottom:

Disable the Display Power Saving Technology section:

Now it's working as expected! (Tested on Thinkpad X1 - graphic: 620)

As per Intel Support, they recommend:

1. Click on the Start button, then search for "Power Options".
2. Click on "Change plan settings".
3. Now click on "Change advanced power settings" to launch the Power Options Advanced Settings.
4. Scroll down until you get to the "Display" section and click on the plus sign to show the sub-menus. Now click on the plus sign next to "Enable adaptive brightness" to expose its settings.
5. Change the settings to off.

Reboot and test for the desired change. If the problem persists:

6. Get into the Intel(R) HD Graphics Control Panel (CUI)
7. Go to the "Power" section
8. On the left navigation panel, select the "On Battery" option
9. More options appear on the main panel; pick "Display Power Saving Technology" | "Disable" | Apply | Reboot and retest.

Answer 8

After a lot of searching (I also tried checking Intel graphics command center settings as well as system power settings, but both without right results, I stumbled upon this solution):

Right click on Desktop and then click on

Intel Graphic Settings -> Power -> On Battery -> Display Power Saving Technology -> Disable

Answer 9

i was facing this problem with a DELL Latitude E5570 with windows 11 and intel HD Graphics 530, the new intel graphics command center does not have the disable powe saving technology option, neither the bios has this option, so, searching I found that I have an app installed called Dell Command Power Manager. In this app there is an option called "Battery extensor" (or something like that because the app is in another language), I activated the battery extensor option and changed the screen brightness to 75% and screen reduced flickering, it only happens when I turn on or off the laptop.
