Frequently asked questions
Can I use my monitor as a green screen?
Yes — open this page, hit Fullscreen, and place the monitor or tablet behind your subject. Most chroma-key software will pick up #00FF00 cleanly.
Is pure green better than green fabric?
A monitor produces a perfectly even, lit green with no shadows or wrinkles, which is often easier to key than physical fabric.
