GUIDED CHECK / ESSENTIAL
Quick Screen Check
A focused route through the patterns that reveal the most common display problems. Thirteen unique stages, including text clarity, with no repeated screens.
SEQUENCE / 12
A useful first look in thirteen unique stages.
Each screen is shown once. When one field checks several things—such as pixels, colour and uniformity—the runner names those purposes together instead of repeating it.
Black screen
Pure #000000 with no overlays, compression or glow.
Dead pixel test
Cycle exact solid colours to find faulty subpixels.
Grayscale
Inspect neutral tones, shadow detail and highlights.
Color banding
Reveal posterisation in smooth light and dark gradients.
Colour test
Inspect solid primaries and progressive saturation.
Screen uniformity
Spot dirty-screen effect, tinting and uneven light.
OLED burn-in
Look for persistent image retention without repair claims.
Backlight bleed
Observe LCD edge leakage and glow in a dark room.
Contrast detail
Separate levels close to black and close to white.
Sharpness & geometry
Check scaling, overscan, lines and one-pixel detail.
Text clarity
Compare crisp black text from display size down to fine print.
Motion response
Observe blur, ghosting and browser frame timing.
