Inspect your display for dead or stuck pixels, measure refresh rate and browser FPS, check ghosting and backlight bleed, and verify colour and resolution. The webcam tools confirm your camera works before a call.
Run these fullscreen for the most accurate view of panel defects.
Panel defects and timing issues are easier to see with full-screen patterns than in everyday desktop use. Dead-pixel and colour pages flood the display; refresh-rate and FPS tools estimate how smoothly frames arrive.
Webcam and mirror pages verify the camera before meetings. For pixel checks, dim the lights and view the screen straight on so faint stuck pixels stand out.
