PNG images can be up to 4096 × 4096 pixels.
Open a solid green screen in fullscreen for pixel and color-channel checks, display uniformity testing, a simple chroma-key background, or a green PNG.
Green uses a bright primary channel that can expose dark, stuck, or tinted pixels quickly. The uniform background can also work as a basic chroma-key surface for small video and photography setups.
Click the preview or Fullscreen to enter. Tap the fullscreen view or move the pointer to reveal the exit button, which hides after a few seconds. Esc also exits. If native fullscreen is unavailable, the view fills the page and browser controls may remain visible.
For a better display check, view several colors in a dim room and keep the browser zoom at its normal level. The tool displays solid browser colors; it does not calibrate the monitor or repair pixels.
