01 / Instructions
How to use this test
Clean the screen gently using its manufacturer’s instructions. Select a colour, enter full screen and inspect each region. Repeat with other colours.
02 / Next step
Understand your result
A dot that remains dark, bright or a different colour across patterns deserves closer inspection. Dust can resemble a defective pixel.
03 / Testing methodology
What this test cannot tell you
This tool does not automatically find or repair pixels. Record your visual observation and consult the display warranty if needed.
