Problem description: My computer’s display turns black and white
While working on your Windows 10 PC, the screen switched from color to black and white, or grayscale, like in the screenshot below. You have no idea what caused this and restarting Windows 10 does not fix the problem.
“disable the Windows 10 color filters”
The easy way is to press the following keyboard shortcut: Windows + CTRL + C. Your screen gets back to color again. If you press Windows + CTRL + C, it turns black and white again, and so on. This keyboard shortcut enables or disables color filters for the screen. These are created for people with sight problems so that they can enable a certain filter and better see what is on the screen.
To disable the active gray-scale color filter, you can also use the mouse or keyboard: open Settings and go to Ease of Access.
Then, in the column on the left, choose Color & high contrast.
On the right side of the Settings, you can see the switch that says Apply color filter and set it to Off.
Now the screen gets back to color.
