Screen & display
Interactive · Runs in this browser
Open distraction-free black, white, red, green, blue, gray, and gradient patterns. Cycle with on-screen controls, keyboard arrows, or screen taps to inspect pixels, tint, banding, backlight uniformity, and image retention clues.
Inspect the display at normal viewing distance while solid white, black, red, green, blue, and gray screens are shown. A browser test cannot repair or certify a physical panel.
Tap the screen or use Left/Right, Space, or Enter to change color. Use Escape or the visible Exit test control to leave.
Transparent method
This tool reports only interactions and browser APIs it can observe. It does not infer hidden hardware specifications or turn unsupported access into made-up results.
Useful context
Look for pixels that stay the wrong color, bright or dark patches, unexpected tint, uneven edges, visible banding, or persistent previous images.
No. Color patterns can help you inspect a panel but cannot guarantee repair of dead pixels or physical damage.
