Windows 10: Screen goes black when pressing lower brightness button

Hello!When I press the "lower brightness" button, my screen goes black, and it returns to normal when pressing the "higher brightness" button.For example, if my brightness is set to 100%, and I press the "lower brightness" button once, my screen goes black immediately; if I keep pressing it multiple times, though my screen is black, the brightness level will go down as normal. The screen turns on again with the corresponding brightness level once I press the "higher brightness" button again.Windows specs:Edition Windows 11 HomeVersion 21H2OS build 22000.434Experience Windows Feature Experie

Black Screen after Log on

Laptop or Desktop (Very important) Windows 10 build 14.586 has a very annoying BUG: That causes Black Screen after login:
To date there is no cure until Microsoft send Update to fix the problem: OK here goes: When you Login and the Screen Goes Black ==>
Go to your Function Keys for Screen Brightness Chose to Lighten the Screen (This will make the screen Bright) so that you can view it.
The BUG is that they reversed (via Software) what the Brightness button does -- So it is currently reversed -- "Lighten" makes it Dark -- "Darken" makes it Bright ==> Go figure Microsoft screw the pooch on this one. . . .

This is for LAPTOP -- I have never seen this on Desktops but they are fixed rather than adjustable

 

Screen goes black if the power cord is connected

Hi Tony,

As the screen goes black I suggest you to refer the Microsoft article on
Troubleshoot black screen problems and check if it helps.

http://windows.microsoft.com/en-us/windows-10/troubleshoot-black-screen-problems

I also see that you are facing issues with the keyboard this might be due to the corruption of keyboard drivers. I suggest you to run the
hardware and devices troubleshooter and check if it helps.

Follow the below steps for the same.

Windows 10 has a built-in troubleshooter to check and fix issues with hardware and devices. I would suggest you to run this troubleshooter. Refer these steps:

• Press Windows key + X, select Control panel.
• Change the view by option on the top right to Large icons.
• Click on troubleshooting and click on the view all option on the left panel.
• Run the Hardware and devices troubleshooter.
• Restart your computer and check if the issue is resolved.

Hope this information is helpful. Please get back to us with the information required, if you need further assistance, we’ll be glad to assist you.

 

How to change desktop PC screen brightness without press the monitor's buttons?

There is a post here that seems to be the same question, but it isn't!

How to lower screen brightness on a Windows 10 Desktop

This is the answer for a laptop, my PC is desktop. It have no battery.

I don't want to press the monitor's brightness button. The button work fine, but the monitor's stand is very weak, pressing the button at everyday morning & night cause loosing VGA cable => lost green color in my monitor. I must hit my monitor to get the green back.

'Radeon Setting' color is horrible. What ever setting (brightness, temperature, contrast), many objects in the screen become harder to see.

Is there another way to change the screen brightness?

My specs: Windows 10 1809, GPU: Radeon Vega8.

Thank you.
