A dead pixel test helps you quickly find defective, dark, or stuck subpixels on your monitor or laptop display. This test displays full-screen pure colors to make any defective pixel immediately visible.
Attempt to revive stuck subpixels by rapidly cycling high-contrast colors in the affected area.
Fill your screen with pure primary, secondary, black, and white fields to inspect overall panel cleanliness.
Inspect OLED and LCD displays for persistent shadow outlines, static HUD retention, and panel burn-in.
