Display testing is visual
ScreenBlack provides browser-based patterns and tools that can make certain visible display characteristics easier to inspect. They are not laboratory instruments, professional repair advice, or a definitive diagnosis of panel hardware.
Results can vary
What you see can be affected by room lighting, viewing angle, browser behavior, scaling, source content, display settings, and the characteristics of the panel itself. A result from one browser test should not be treated as a measured pass/fail score.
Hardware decisions
Before returning, repairing, or replacing a monitor, phone, or TV, repeat the test and consult the manufacturer's specifications, pixel policy, warranty, and support documentation.
