Display Tests
Display tests help you inspect panels with solid fields, color and contrast aids, uniformity checks, and best-effort refresh or motion tools. Dead Pixel Test includes optional rapid cycle with calm defaults.
Start with Dead Pixel Test or Color Test for visual defects, then open specialized pages for uniformity, levels, refresh estimates, or HDR-related signals. Pair with Device Information when tickets need size and DPR context.
