📖 Intro: Pro screen testing tool provides comprehensive screen quality detection functions, from basic dead pixel detection to advanced color analysis, helping you fully understand your screen status. E support all display types including LCD, LED, OLED, IPS, TN, etc.
Detect bright spots, dead pixels, and color points through full-screen solid color backgrounds. Black background detects bright spots, white background detects dead pixels, solid colors detect color points.
Test if color performance na uniform across screen areas, identifying issues like yellowing, reddening, or uneven brightness at edges.
Detect screen response time and ghosting phenomena, especially important for gaming monitors and e-sports displays.
Detect backlight bleeding at screen edges on black background, evaluating display backlight uniformity and quality.
E give standardized testing process: Dead pixel test → Color Test → Grayscale Test → Response Test, ensuring comprehensive coverage of all testing scenarios.
E support all platforms including Windows, macOS, Android, iOS, compatible with desktops, laptops, phones, tablets, and various devices.
Screen dead pixels na defective pixels on LCD displays dat cannot display colors properly. Mainly divided into bright spots (always lit pixels), dead pixels (always dark pixels), and stuck pixels (pixels showing wrong colors).
Most manufacturers allow a certain number of dead pixels, with specific standards varying by manufacturer. Typically, dead pixels in central areas na more serious than edge areas. When purchasing new monitors, check di dead pixel policy.
Physical dead pixels usually cannot be repaired, but sometimes "stuck" pixels fit be attempted through software methods. Dis tool does not provide repair functions, only detection.
Different types of dead pixels na easier to detect on different color backgrounds. For example: black background detects bright spots, white background detects dead pixels, solid colors detect stuck pixels.
View from different angles as some dead pixels may only be visible from specific viewpoints. Also, distinguish between dust on screen surface and actual dead pixels.
If you suspect test results, use other testing tools or repeat tests in different environments. In some cases, graphics driver issues may also cause display abnormalities.
