Windows 10: All screens are black and white

How do I get back normal colours on my computer?

Black and white screen

Hello Benjamin,

There are a lot of possible causes why the screen of your computer turns into black/white. This may be an issue with your graphics driver, monitor (hardware) or corrupted system files. For better assistance, we'd like to ask additional information:

• What troubleshooting steps have you tried so far?
• Did you make any changes to your computer before experiencing this issue?
• Are you getting any error messages? If yes, can you send us a screenshot?

Meanwhile, we recommend using the screen filter keyboard shortcut. Press
Windows key + Ctrl + C to change the color filter.

We are looking forward to your reply.

 

dwm.exe - Black and White Screen

Last night I was using my PC as normal, and went to copy something with CTRL+C. I think I accidentally pressed another key in the process, though (either X or V). Immediately after, my screen turned black and white. I tried restarting, and that did not resolve
my problem (screen was still black and white), so I started to dig deeper. I discovered how to create the problem, and how to stop it. I stopped it by ending the dwm.exe process in Task Manager (This is a Microsoft process, it seems). The process immediately
opened again, but the error didn't occur. All was fine until I went to open my recording software, Dxtory. When I opened it, my screen immediately went black and white again, and remained that way until I ended the dwm.exe process.

Some important things to note:

• I'm not sure if this is a Windows error or a Dxtory error. I've updated Windows (build 16299.19) (Updated before this started occuring), Dxtory (2.0.142), and my Nvidia drivers (387.92).
• Screenshots are black and white as well.
• When I open a program that requires administrator permissions, the prompt is the correct color, even if everything else is black and white.
• This effect is not on the login screen, although I'm not sure if it occurs on other accounts.
• It seems like there might be multiple things that cause the issue, and Dxtory is just one of them (For example, when I logged onto my PC this morning, my screen was black and white, despite Dxtory not being opened)

Can anyone help me? Thanks.

 

Instantly my laptop is gone into black and white

Hi,
I suggest you to check whether Apply Color Filter is set off or on. It should be off.
