Laptop dimming display on dark backgrounds












6















My Acer laptop running Windows 10 has a very annoying feature: when running on battery, the LCD backlight dims gradually when displaying a dark screen and brightens gradually when displaying light screen.



This is especially annoying when switching between my IDE (which is dark and pleasant to the eyes) and a webpage.



I've figured out that this is happening only on battery, and no matter the display brightness, it happens unless I plug it in. I've checked if there's some setting in the Windows power settings, but nothing popped out at me (my laptop for instance doesn't have adaptive screen brightness).

          An obscure forum post pointed me in the right direction:





          1. Search Windows for 'Intel'

          2. Select 'Intel HD Graphics Control Panel'

          3. Click the 'Power' square button

          4. Click 'On Battery' tab

          5. Disable 'Display Power Saving Technology' (I see it as the last option)




          Here's the option in Intel's HD Graphics Control Panel:



          Intel HD Graphics Control Panel: Display Power Saving Technology



          Save your eyes and turn off "Display Power Saving Technology".

            Another way to open Intel HD Graphics Control Panel is to right click on your desktop and select Intel Graphics Settings. I'm glad I found this answer. I couldn't stand the strain this has caused my eyes a few months.

          I had a very similar problem using a ThinkPad T460s and a NEC MultiSync EA273WMi monitor. Using dark themes in my IDE the screen dimmed after a few seconds.



          My problem was resolved by changing the "DV Mode" on the screen from "Dynamic" to "Standard".

            For anyone who doesn't have the Power Saving Technology option in Intel Graphics Control Panel (I only had a Panel Self-Refresh Enable/Disable option) follow the instructions in the first answer, from AMART53, in this forum, https://forums.intel.com/s/question/0D50P0000490XXpSAM/disable-intel-display-power-saving-technology-in-plugged-in-mode?language=en_US.



            I have copied the answer below.



            AMART53:



            "launch regedit



            go to :



            [HKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4d36e968-e325-11ce-bfc1-08002be10318}000]



            (for me it was in 0001)



            find the value FeatureTestControl



            Open the calculator in programmor mode, go in HEX and write the value written, look at the binary, it give you for exemple:



            HEX : c200



            BIN : 110000100000000



            change the 5th bit from the end to 1:



            1100001000010000



            Put in on calculator in programming mode/BIN and get the HEX value



            BIN : 1100001000010000



            HEX : c210



            modify the register with regedit and put the new HEX value in FeatureTestControl



            Restart your computer"



            This worked for me although it seems insane something as specific as changing 1 binary digit would be needed to solve the problem.

                      For anyone who doesn't have the Power Saving Technology option in Intel Graphics Control Panel (I only had a Panel Self-Refresh Enable/Disable option) follow the instructions in the first answer, from AMART53, in this forum, https://forums.intel.com/s/question/0D50P0000490XXpSAM/disable-intel-display-power-saving-technology-in-plugged-in-mode?language=en_US.



                      I have copied the answer below.



                      AMART53:



                      "launch regedit



                      go to :



                      [HKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4d36e968-e325-11ce-bfc1-08002be10318}000]



                      (for me it was in 0001)



                      find the value FeatureTestControl



                      Open the calculator in programmor mode, go in HEX and write the value written, look at the binary, it give you for exemple:



                      HEX : c200



                      BIN : 110000100000000



                      change the 5th bit from the end to 1:



                      1100001000010000



                      Put in on calculator in programming mode/BIN and get the HEX value



                      BIN : 1100001000010000



                      HEX : c210



                      modify the register with regedit and put the new HEX value in FeatureTestControl



                      Restart your computer"



                      This worked for me although it seems insane something as specific as changing 1 binary digit would be needed to solve the problem.

                          For anyone who doesn't have the Power Saving Technology option in Intel Graphics Control Panel (I only had a Panel Self-Refresh Enable/Disable option) follow the instructions in the first answer, from AMART53, in this forum, https://forums.intel.com/s/question/0D50P0000490XXpSAM/disable-intel-display-power-saving-technology-in-plugged-in-mode?language=en_US.



                          I have copied the answer below.



                          AMART53:



                          "launch regedit



                          go to :



                          [HKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4d36e968-e325-11ce-bfc1-08002be10318}000]



                          (for me it was in 0001)



                          find the value FeatureTestControl



                          Open the calculator in programmor mode, go in HEX and write the value written, look at the binary, it give you for exemple:



                          HEX : c200



                          BIN : 110000100000000



                          change the 5th bit from the end to 1:



                          1100001000010000



                          Put in on calculator in programming mode/BIN and get the HEX value



                          BIN : 1100001000010000



                          HEX : c210



                          modify the register with regedit and put the new HEX value in FeatureTestControl



                          Restart your computer"



                          This worked for me although it seems insane something as specific as changing 1 binary digit would be needed to solve the problem.
