ScreenDetect

Find out what may be wrong with your screen

ScreenDetect helps people turn a vague screen problem into a clearer next step. A dead pixel, dark patch, ghosted image, missed touch area, strange color, or unexpected refresh rate can be difficult to describe. ScreenDetect gives visitors a practical way to look more closely before deciding whether to keep testing, contact the manufacturer, make a warranty claim, or get help.

The site is careful about its limits. A browser test can show useful evidence and help narrow down what someone is seeing, but it cannot conclusively diagnose every hardware problem.

Six ways to check a display

The main tests are designed around the symptoms people notice first:

• Pixel test — Find and mark pixels that appear stuck, dead, or different from the surrounding display.
• Backlight bleed test — Use controlled screens to look for uneven light around the edges of a display.
• Burn-in test — Check for image retention or a ghosted shape that remains visible after the original image is gone.
• Touch test — Trace a grid across a touchscreen and identify areas that do not respond as expected.
• Color test — View solid color patterns to make tint, banding, and uneven display behavior easier to spot.
• Refresh-rate test — Check how quickly a browser is presenting frames, with clear context about what that result can and cannot tell you.

From a symptom to evidence

ScreenDetect helps visitors explain a problem to someone else. The touch test can produce a shareable result card, making it easier to show a missed area to support or a repair provider. The pixel test supports marking and checking a suspected issue more closely instead of relying on a quick glance.

Bounded repair and calibration guidance

Some screen issues may be worth a limited, carefully explained attempt before escalation. ScreenDetect includes guided stuck-pixel and image-retention sessions, along with monitor calibration patterns for gamma, contrast, tint, and black levels.

These experiences include warnings, timers, stop guidance, and clear boundaries around when testing is no longer useful. They do not promise that an animation will repair every panel or replace professional service.

When the problem may be physical damage

ScreenDetect helps visitors move from a symptom to relevant guidance for pressure, heat, water, dark spots, lines, ghost touch, cracked glass, and other forms of physical damage. Those guides focus on practical decisions: when to stop testing, how to document what happened, when to back up data, and when a warranty or repair conversation makes more sense.

Device and buying guidance

The site provides screen information for individual devices and display categories. That context helps visitors understand why the same symptom can mean something different on an OLED phone, a laptop panel, or an external monitor.

What Valiance Labs built

Valiance Labs built ScreenDetect as an owned and operated web property around a simple idea: people need a useful observation before they can make a good decision about a screen problem. Every part of the site connects the same journey—see the symptom, gather better evidence, understand the limits, and choose what to do next.
