Screen dims with dark content on screen

[JuicyFruitz]

Why does my display dim, when there is dark content on the screen? I've disabled adaptive brightness and put everything on performance mode. But it seems when I switch to like a music video or the spotify window which is black, the screen brightness dims. And when I go back to my chrome browser which is all white, the screen brightens up again. Someone help.

Hey there! @JuicyFruitz,

Does the issue persist on the BIOS page?

Please share the product number of the PC to assist you better.

Try the steps recommended below.

1. Go into "Control Panel" and then "Power Options".

2. Click the "Change plan settings" link next to whichever plan you are currently using and then click "Change advanced power settings".

3. In this new window click "Display" to open up the listings under it.

4. Now locate and click each of the following..."Display brightness", "Dimmed display brightness" and"Enable adaptive brightness".

5. Change each of these to the settings you wish, then click the "Apply" button and finally the "OK" button.

6. You should be good.

Also, Select Start, choose Settings, then select System > Display. Under Brightness and color, move the Change brightness slider to adjust the brightness. (If the slider isn't there, see the Notes section below.)

Some PCs can let Windows automatically adjust screen brightness based on the current lighting conditions. To find out if your PC supports this, in Display settings, under Brightness and color, look for the Change brightness automatically when lighting changes check box and then select it to use this feature. This automatic setting helps make sure your screen is readable wherever you go. Even if you use it, you can still move the Change brightness slider to fine-tune the brightness level.
Notes: 
You might not see the Change brightness slider on desktop PCs that have an external monitor. To change the brightness on an external monitor, use the buttons on it. 
If you don't have a desktop PC and the slider doesn't appear or work, try updating the display driver. In the search box on the taskbar, type Device Manager, and then select Device Manager from the list of results. In Device Manager, select Display adapters, then select the display adapter. Press and hold (or right-click) the display adapter name, then select Update driver and follow the instructions.

Lastly, Try updating BIOS, graphics and chipset drivers on your PC and check if it helps.

Try updating the drivers on the PC using HP support assistant.

If the issue persists in BIOS it is a hardware issue with the PC.
