Green Screen
A solid green screen for testing green subpixels and judging panel uniformity. Because our eyes are most sensitive to green, this field is especially good at revealing faint banding and brightness fall-off. Use it as a quick test pattern or a green ambient light.
What you can use it for
- Push every green subpixel to check it across the panel
- Catch faint banding and brightness changes the eye notices most in green
- Find stuck pixels that fail to render green
- Set a green wash for lighting or mood
How it works
- 1. Customize. Open the Customize panel to set text, colors, theme, and animation speed to your liking.
- 2. Go fullscreen. Click Fullscreen for an immersive, distraction-free display on any screen.
- 3. Done. No login, no install, nothing to download — it runs instantly in your browser and your settings are remembered.
Frequently asked questions
Why test with green specifically?+
The human eye resolves green detail better than red or blue, so subtle uniformity and banding problems usually show up first on a green field.
Is this a chroma-key green screen?+
It's a solid green display, so it can stand in for a small backdrop in a pinch. For real video keying, proper chroma-green fabric or paint gives much cleaner results.
