Frequently Asked Questions
What is a black screen tool and why do I need it?
A black screen tool displays solid colors on your entire screen for various purposes including energy saving, dead pixel detection, screen cleaning, and meditation. It's particularly useful for OLED displays where black pixels save up to 58% battery life.
How does black screen save battery on OLED displays?
OLED displays work by lighting individual pixels. When displaying black, OLED pixels are completely turned off, consuming no power. This can save up to 58% battery compared to displaying white or bright colors, making it perfect for energy conservation.
Can I use this tool to detect dead pixels?
Yes! Solid color backgrounds, especially black, make dead pixels and stuck pixels easily visible. Dead pixels appear as black dots on colored backgrounds, while stuck pixels show as colored dots on black backgrounds. This helps identify display quality issues.
How do I navigate between different colors?
You can navigate using arrow keys (left/right), spacebar (next color), or by clicking different screen areas. Click the left 20% of screen to go back, right 20% to go forward, or center area to exit. Press ESC to exit anytime.
Is this tool safe for my screen?
Yes, this tool is completely safe. It simply displays solid colors without any harmful effects. In fact, it can help extend OLED screen lifespan by reducing power consumption and preventing burn-in through varied color display.
