If your computer screen suddenly turns black and white (grayscale), it usually means a display setting has been changed accidentally or there's a software glitch. Here’s how you can fix it depending on your operating system:
For Windows:
1. Check Color Filters:
-
Press Windows + Ctrl + C — this is a shortcut that toggles color filters on and off. If it’s enabled, pressing it again will restore normal colors.
-
Or go to:
-
Settings > Ease of Access > Color filters (or Accessibility > Color filters)
-
Make sure the toggle for Turn on color filters is off or the filter is set to “None.”
-
2. Check Graphics Settings:
-
Right-click on the desktop and select Display settings.
-
Click on Advanced display settings or Graphics settings.
-
Look for any color calibration settings or profiles and reset them to default.
3. Update or Reinstall Graphics Drivers:
-
Open Device Manager (Windows + X > Device Manager).
-
Expand Display adapters.
-
Right-click your graphics card > Update driver.
-
Or uninstall and restart your PC to reinstall the driver.
For macOS:
1. Check Accessibility Settings:
-
Go to System Preferences > Accessibility > Display.
-
Make sure Use grayscale is unchecked.
2. Check Display Profile:
-
Go to System Preferences > Displays > Color tab.
-
Choose a different color profile or click Calibrate to create a new one.
General Tips:
-
Restart your computer — Sometimes a simple restart fixes temporary glitches.
-
Check cables and connections — A loose or damaged cable can cause display issues.
-
Try an external monitor — If available, connect to see if the issue persists (helps identify hardware vs. software problem).
