GUIDED CHECK / ESSENTIAL
Quick Screen Check
A focused route through the patterns that reveal the most common display problems. 13 unique stages, from dead pixels to motion, with no repeated screens.
SEQUENCE / 10
A useful first look in 13 unique stages.
Each screen is shown once, with a short hint about what to look at. 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 dead and stuck subpixels.
Grayscale & gamma
Neutral steps, a gamma chart and RGB channel tracking.
Color banding
Reveal posterisation in smooth light and dark gradients.
Screen uniformity
Spot dirty-screen effect, tinting and uneven light.
Backlight bleed & blooming
LCD edge leakage, IPS glow and local-dimming halos.
Contrast detail
Black crush, white clipping and checkerboard contrast.
Sharpness & geometry
Check scaling, overscan, lines and one-pixel detail.
Text clarity
Text at nine sizes, light-on-dark fringing and a chroma 4:4:4 check.
Refresh rate & motion
Measured refresh rate, frame pacing, blur and ghosting.
