02
What to enter and check
Black helps reveal bright/stuck pixels, white reveals dark pixels, and RGB screens expose color subpixel faults.
A point visible in the same location across patterns may indicate a pixel fault. Rule out dust and reflections, then check the manufacturer's pixel policy.
Practical example
For a new monitor, cycle from black through RGB and grayscale and check whether a suspicious point stays in exactly the same location.
How to read the result
A point visible in the same location across patterns may indicate a pixel fault. Rule out dust and reflections, then check the manufacturer's pixel policy.
