How to Fix Monochrome Screen on vivo Y51 Pro

If your vivo Y51 Pro suddenly shows everything in black and white, it can feel like the display is broken. Colors disappear, apps look dull, and even photos lose their detail. In most cases, this is not a hardware issue, it is usually caused by a setting that was accidentally turned on.

The good news is that you can restore the colors in just a few steps.

Why Your vivo Y51 Pro Screen Turned Black and White

• Grayscale mode is enabled in accessibility settings.
• Bedtime or Eye protection mode is affecting screen colors.
• Developer options are forcing a monochrome display.
• A third party app is overriding display settings.
• Temporary software glitches affecting the display.

Check Grayscale Settings

Grayscale mode removes all colors from your screen to reduce eye strain or improve focus. If this setting is turned on, your entire display will appear in black and white.

1. Open Settings, and then tap Accessibility.
2. Tap Vision or Visibility enhancements, and then look for Color correction.
3. Turn off Grayscale, and then return to the Home screen.

Disable Eye Protection or Bedtime Mode

Some display modes reduce color intensity, and in certain cases, they can make the screen look almost monochrome. Turning them off helps restore normal color balance.

1. Open Settings, and then tap Display.
2. Tap Eye protection, and then toggle it off.
3. Check Bedtime mode, and then disable it if it is turned on.

Turn Off Developer Options Grayscale

Developer settings can force your screen into a monochrome mode. This option is often enabled accidentally when exploring advanced settings.

1. Open Settings, and then tap System management.
2. Tap Developer options, and then scroll to Simulate color space.
3. Select Disabled, and then exit the settings menu.

Restart Your Phone

A simple restart clears temporary glitches that may affect display settings. It refreshes the system and can restore colors instantly.

1. Press and hold the Power button, and then tap Restart.
2. Wait for the device to reboot, and then check the screen colors.

Remove Problematic Apps

Some apps can change display behavior, especially screen filters or accessibility tools. Removing them can fix the issue if the problem started after installing a new app.

1. Open Settings, and then tap Apps.
2. Tap App manager, and then review recently installed apps.
3. Uninstall suspicious apps, and then restart your phone.

If your vivo Y51 Pro screen suddenly turned black and white, it is almost always a settings issue. Once you disable grayscale or related features, your display should return to normal with full color.
