Good to know

  • An internet connection is required. Nothing works offline.
  • Adding it does not request permissions or send notifications.
  • The app window and browser tabs may use separate storage, so practice records can look different.
  • Menu names and positions vary by browser and version. To remove it, use your browser’s or device’s app settings.

Display

Screen test

Step through color patterns to look for blotches or dead pixels.

Getting the controls ready…Still loading. Check your connection, then reload the page.

Choose a color, inspect the panel, then confirm only what you saw yourself.

Fullscreen opens without text or buttons. Space / →: next · ←: previous · H: show/hide control buttons · tap the pattern: next · Esc: exit fullscreen. Read these shortcuts before hiding controls.

Not started

Current color: Red (1/13)

Visual confirmation only — not automatic dead-pixel detection or certification.

Details and limits

Step through solid color patterns while you inspect the panel yourself.

How to check

Pick a named color or advance to the next one, then use fullscreen if you need to inspect edges. There is no automatic flashing loop.

If something feels wrong

If you see blotches, change brightness, reflections, or a screen film, then recheck the same pattern.

Limits

We do not claim automatic dead-pixel or backlight-bleed detection. Outcomes are user-confirmed.

FAQ

Fullscreen failed.

Browser policy may block it. Windowed patterns still support visual checks.

Can a screenshot prove no dead pixels?

No. Screenshots do not prove panel health.
