What a green field is for
Chroma Key Background
Use your second monitor or TV as a green screen backdrop for video production. Most video editing software and streaming tools can remove this green background and replace it with any image or video.
Video Call Background
Place a screen showing green behind you during video calls. Applications like Zoom, Teams, and Google Meet can use chroma key to replace the green with a virtual background.
Streaming & Content Creation
Streamers and YouTubers can use a monitor as a portable green screen for facecam overlays, thumbnail creation, and special effects shots.
Green Subpixel Testing
Test the green subpixel of every pixel on your display. Stuck or dead green subpixels appear as dark spots on a full green screen.
