The application helps you detect bad pixels and inspect your screen's uniformity, by presenting 5 uniformly colored screens (in black, white, red, green and blue). Custom colors can be added to the default colors.
The users must use their own eyes to determine the screen uniformity or to find any defective pixels. The application is just a helper and has no knowledge of the actual display state. It can not by itself measure the uniformity or find by itself defective pixels.
