Whitescreen.dev Black Screen is a clean, distraction-free fullscreen black background tool. Use it for dark-room comfort, pixel inspection, contrast testing, or ambient light control. No overlays. No gradients. Just pure black.

How to Use

• Step 1: Open this page.
• Step 2: Click anywhere to activate fullscreen mode.
• Step 3: Use the black screen for testing, cleaning, or low-light viewing.

Why Use a Black Screen?

• Monitor cleaning: A black screen makes dust and smudges stand out clearly.
• Dead pixel detection: Bright or glowing pixels are easier to spot against black.
• Eye comfort: Reduces glare in dark rooms and minimizes visual strain.
• Contrast reference: Useful when comparing with white or color screens.

Black Screen for Dark-Room Comfort and Display Diagnostics

A fullscreen black screen is highly effective for evaluating display behavior in low-light conditions. While white highlights surface marks, black reveals issues that only appear in darker scenes — especially on LED backlit monitors and TVs.

Backlight Bleed, Glow, and Uneven Blacks

On LCD and LED displays, black is produced by blocking light rather than turning pixels fully off. In dark environments, this can expose backlight bleed, edge glow, or uneven brightness zones.

• Backlight bleed: Light leakage from corners or edges.
• IPS glow: A faint glow effect visible at certain angles.
• Uniformity drift: Areas that appear gray instead of deep black.

OLED Behavior and True Black

On OLED screens, black pixels can switch off completely, producing near “true black.” A fullscreen black screen helps confirm pixel consistency. If you notice faint brightness where black should be absolute, it may relate to panel settings, reflections, or adaptive brightness features.

Detecting Glowing or Stuck Pixels

Black backgrounds are ideal for identifying pixels stuck in an “on” state. Bright dots stand out clearly. For best results, enter fullscreen mode, dim the room lights, and scan the display slowly from edge to edge.

Additional Use Cases

• Night comfort mode: Maintain a dark room environment while keeping the display active.
• Cinema / projector pause screen: Neutral transition screen between scenes.
• Photography setups: Block unwanted light reflections during shoots.
• Contrast comparison: Alternate with white or red screens to test extremes.

Technical Notes

• Perceived black varies: LCD panels may appear gray depending on brightness levels.
• Ambient reflections matter: Test in a darker room for accurate evaluation.
• Brightness adjustment: Lower brightness to evaluate uniformity more precisely.
