Частые вопросы
A dead pixel is a permanently dark dot that fails to light up. To find one, use the solid white test screen; a dead pixel will appear as a small black spot that doesn't change on other colors.
A dead pixel produces no light (dark dot). A bright spot glows where it should be dark, often visible on black test screens due to pressure or backlight issues.
No, this is a diagnostic tool only. Truly dead pixels require screen replacement. Stuck pixels might be helped by external pixel-fixing software.
Use the black screen test in a dark room and reduce brightness using the slider. Backlight bleed appears as light leaking from the screen's edges.
Policies vary, but many manufacturers allow 3-5. Check your warranty; clusters of defects may qualify for replacement.
Black or green lines often indicate faulty panel circuitry or a damaged ribbon cable. These lines, visible in pattern tests, usually need professional repair.
An orange tint can indicate color calibration issues, cable damage, or OLED degradation. Test with gray screens and check display settings first.
Image retention is temporary ghosting that fades. Burn-in is permanent uneven aging, common in OLEDs. Both show ghost images but burn-in is irreversible.
Yes, displaying test colors is safe and does not cause damage. It simply reveals existing defects without harming the display.
The tool works on any device with a web browser: laptops, desktop monitors, tablets, smartphones, and even some smart TVs.
