About Full Blue Screen
The full blue screen tool is primarily used by technicians and videographers to calibrate monitors and test the blue sub-pixels. It can also be used to create a specific ambient lighting mood in a room using your monitor or TV.
How to use the Fullscreen Tool
Click the "Fullscreen Preview" button above. Your browser will hide all UI elements and display the pure color. This is perfect for:
- Finding dead or stuck pixels on your monitor.
- Checking for backlight bleed on LCD panels.
- Using your screen as a makeshift light source or reading light.
- Cleaning your display (dust is easier to see on a solid color).
To exit, simply press the ESC key or tap the screen on mobile.
