About Black Screen Tool

A black screen is essential for testing your monitor's backlight quality, detecting stuck bright pixels, and as a simple screen blanking tool. For OLED displays, a black screen uses minimal power since pixels are actually turned off. Our tool provides various dark shades to help test different aspects of your display. For comprehensive display testing, also try our Dead Pixel Tester and Refresh Rate Tester.

Common Uses for a Black Screen

Display Testing

• Backlight bleeding detection.
• Stuck pixel identification.
• IPS glow assessment.
• Contrast ratio testing.

Practical Uses

• Screen blanking.
• Power saving (OLED).
• Dark room ambiance.
• Presentation mode.

Black Screen Variations Explained

Pure Black (#000000)

Absolute black with zero light. On OLED displays, this means pixels are completely off, saving power and preventing burn-in.

Rich Black (#010203)

Slightly lighter than pure black, useful for comparing true black reproduction on your display.

Charcoal (#1A1A1A)

A very dark gray useful for testing how well your display handles near-black gradients.

Dark Gray (#2D2D2D)

Dark enough to reveal backlight issues while light enough to show crushed blacks.

Tips for Using Black Screen

For Backlight Bleeding: Test in a completely dark room for the most accurate results. For detailed testing, use our Screen Bleeding Test.
For Stuck Pixels: Carefully scan the entire display for any bright spots. Use our Dead Pixel Tester for comprehensive pixel testing or our Dead Pixel Fixer to fix stuck pixels.
For OLED Power Saving: Use pure black (#000000) for maximum power efficiency on OLED displays.
For Contrast Testing: Cycle through the dark variations to test your display's ability to distinguish near-black shades.
For Presentations: Use as a screen blanking tool during presentations or when you need to temporarily hide your screen. Also check your screen resolution.
