What can you use a green screen for?
- checking how a display renders pure green
- identifying pixel/display irregularities
- helping reveal pixels that do not reproduce the green channel correctly
- providing a solid green background
- simple chroma-key/background experiments where a display-sized green surface is sufficient
- switching among White, Black, Red, Green and Blue for basic visual display checking
This is a solid green display, not a replacement for a professional large green-screen backdrop. Switching among White, Black, Red, Green and Blue can help reveal different display defects.
How to use the Green Screen
- Choose Green or another screen color.
- Click OPEN FULLSCREEN.
- Exit fullscreen normally when finished.
