Pixel & Brightness Test
This image shows how black and white screens are commonly used together to check a display for hidden problems that normal daily use often hides from the eyes. The dark screen helps reveal dead pixels, backlight bleeding, and uneven edges, while the white screen makes brightness issues, discoloration, and faint marks easier to notice. Testing multiple devices in the same setup highlights how screen quality can differ even under similar conditions. The focused environment reflects careful inspection rather than casual usage. Such setups are often used after buying a new device or repairing a screen. Overall, the image clearly explains why simple color screens are effective for display testing.
