Use fullscreen and manual brightness for best results.
Some modes may be uncomfortable at high brightness.

HOW TO USE

1) Choose a MODE on Page 1.

2) Press START for fullscreen panel patterns.

3) Adjust brightness, refresh, gaming mode or overdrive on your device.

4) Exit with ESC or tap/click anywhere.

WHAT EACH MODE REVEALS

Inversion: checker shimmer and voltage artifacts.

Overdrive: overshoot halos, smear and asymmetric transitions.

Dithering/FRC: near-grey shimmer and temporal noise.

Scan: rolling scan direction, useful when filmed.

SAFETY + COMFORT

Pulse mode: avoid if flicker-sensitive; keep amplitude low.

OLED: use short sessions and avoid high brightness.

Tip: take breaks if you notice eye strain or headache.

WHAT THIS TOOL IS FOR

Experimental Display Lab is a visual-first panel test suite.

It helps reveal inversion shimmer, overdrive ghosting and FRC dithering.

It also includes scan-direction and microcontrast pulse patterns.

WHO USES IT?

Monitor enthusiasts, display reviewers, gamers, repairers and calibration hobbyists.

Use it to compare panels or settings, not for certified measurement.

It is useful when checking strange shimmer, flicker, halos or temporal noise.

FAQ

Is it a lab meter? No — it is a visual-first enthusiast test suite.

Why does every panel differ? Subpixel layout, overdrive and processing vary.

Can it measure exact ms? Use instruments for absolute values.

How do I exit? ESC or tap/click screen.

BEST TEST CONDITIONS

Use native resolution, 100% browser zoom and fullscreen mode.

Turn off unnecessary image processing when testing a TV or monitor.

Keep notes on brightness, refresh rate, overdrive and game mode.

MINI BLOG: PANEL ARTIFACTS

  • Inversion can appear as shimmer or checker movement.
  • Overdrive can reduce blur but add bright or dark halos.
  • FRC can simulate extra colours with temporal patterns.
  • Scan tests are easier to interpret when filmed.
