Pro tips
- Use a White screen as a free ring light for Zoom, Teams or Google Meet — position a second monitor beside your face for instant soft lighting.
- Switch to Yellow for late-night reading — warmer than white, it reduces blue light exposure and is easier on your eyes than your default screen.
- Use Red to preserve your night vision while stargazing — red light has the least impact on dark-adapted eyes.
- Display Green fullscreen as a free chroma key background for OBS, Zoom or Streamlabs — no physical green screen required.
- Alternate between White, Black, Red, Green and Blue fullscreen to run a complete dead pixel test on any monitor.
- Use the Lightness slider to dial in exact brightness without touching your system settings — useful for photography and video lighting.
- Download any colour at up to 8K resolution as a PNG — ideal for design mockups, presentation backgrounds or wallpapers.
- Place paper on a fullscreen White screen at full brightness to use your laptop as a free lightbox for tracing and illustration.

How do I check my monitor for dead pixels?
Display a solid colour fullscreen — white, red, green, blue and black — and look for any spots that don't match the background. Dead pixels appear as black dots on a white screen, or bright dots on a black screen. Cycle through colours using the arrow keys.
How can I use my screen as a light source for video calls?
Open a fullscreen white display on a second monitor or tablet and position it beside your face. The bright white screen acts as a soft diffused light source, improving your appearance on Zoom, Teams or Google Meet without buying a ring light.
Is yellow light better than white for reading at night?
Yellow light causes less eye strain than white during extended reading because it reduces blue light exposure. A yellow screen set to medium brightness mimics the warm tone of e-readers and reading lamps, making it more comfortable for late-night use.
How do I use my laptop as a lightbox for tracing?
Display a fullscreen white screen at full brightness and place your paper directly on top of the screen. The backlight will illuminate your reference drawing through the paper, turning your laptop into a free lightbox for tracing or animation.
What colour screen is best for photography lighting?
White is the most versatile — it provides neutral bright light. Use yellow for warm-toned portraits, and adjust the lightness slider to control intensity without changing your system brightness settings.
Can I use a green screen online for free?
Yes — select the green colour option to display a fullscreen chroma key green background on your monitor. This works as a free virtual background for webcam software like OBS, Zoom or Streamlabs without buying a physical green screen.
