Online Screen Tests

Free online screen tests for monitors, laptops, phones, and tablets.

Choose the right screen test for dead pixels, stuck pixels, touch failures, broad color checks, backlight bleed, OLED burn-in, or refresh rate. Start with what you can see or feel, then use the result to choose the right next step.

Choose the right screen test.

Start with what you can see, feel, or measure. Choose the focused screen test that best matches the problem you’re trying to check.

Touch Screen Test

Start here if taps are missed, touch is delayed, part of the screen stops responding, or the screen reacts by itself.

Open Touch Screen Test

Pixel Test

Use fullscreen white, black, gray, and RGB patterns to distinguish dead, stuck, and hot pixels, rule out false positives, and record the defect location.

Open Pixel Test

Screen Color Test

Start here when the screen looks tinted, patchy, uneven, too dark, or difficult to classify.

Backlight Bleed Test

Compare bright corners and edge glow in dark scenes, including backlight bleed and IPS glow.

Burn-In Test

Check lingering logos, interface shadows, image retention, and likely OLED burn-in.

Refresh Rate Test

Measure the browser’s active refresh rate when motion feels capped or a high-refresh display seems stuck at 60Hz.

How to get a useful result from a screen test.

Good evidence depends on controlled setup, repeatable patterns, and knowing what a browser test cannot prove. Follow these steps before choosing what to do next.

Prepare the screen

Control the conditions before you decide that a display is failing.

  • Clean the panel and remove reflections or smudges.
  • Disable adaptive brightness and dynamic display modes where relevant.
  • Use the actual device with the browser tab focused.

Look for a repeatable pattern

A useful result stays consistent when you inspect it carefully and retest it under the same conditions.

  • Inspect from normal viewing distance before moving closer.
  • Compare the patterns designed for the defect you are checking.
  • Watch whether the result changes with viewing angle or room light.

Know what the result means

Browser testing can reveal repeatable visible or touch behavior, but cannot confirm every hardware or policy decision.

  • Use the result to choose a problem, damage, repair, or evidence route.
  • Do not treat it as proof of an exact failed component or warranty eligibility.
  • Stop testing if pressure, liquid, heat, cracking, or worsening behavior is involved.

If the screen looks bruised, shows pressure lines, has unstable touch, changed after water or heat, or seems to be getting worse, treat it as a damage-first problem instead of a browser test problem.

What to do after testing.

Use the result to decide what to do next. Browser repair only fits narrow cases such as stuck pixels or mild OLED retention; it cannot repair cracks, liquid damage, spreading lines, or touch-layer failure.

The result is unclear

Use the visible pattern to understand what the screen problem could mean.

Understand the screen problem

Something caused the problem

Pressure, liquid, heat, cracking, or worsening behavior should be evaluated through damage guidance.

Check damage guidance

A limited repair may fit

Choose a repair option only after the defect class is reasonably clear.

You need evidence for support
