PanelCheck
Trust, but verify your pixels.
TV display inspection
Focused visual tests for inspecting your TV display.
PanelCheck is a TV display inspection app for Apple TV, Android TV / Google TV, and Amazon Fire TV. It provides visual test patterns for near-black and near-white detail, grayscale, gradients, color, uniformity, and motion.
Each test is designed to answer a specific visual question, with simple on-screen guidance explaining what to look for.
Designed for TV
Apple TV requires tvOS 17 or later. Android TV / Google TV requires Android 7.0 or later on a compatible TV device. Check the store links above for current availability and device compatibility, including the Amazon Fire TV build. Roku is in development.
Navigate with your TV or streaming device remote. Adjust test parameters, open guidance when you need it, and move between tests without menus getting in the way.
PanelCheck is an inspection tool, not a calibration instrument. What you see can depend on your TV settings, room lighting, your streaming device or TV platform, and the rest of the display chain.
Black, Grayscale Steps, Color, and Motion are free. A permanent, one-time in-app purchase unlocks Near Black, Gradient, Near White, Uniformity, and Moving Uniformity. No subscription; the app shows the localized unlock price supplied by your store.
No account, no ads, and no analytics or tracking.
