BANDING TEST

P769

BEST FOLDER: /banding-test/

Choose a smooth ramp to reveal banding, posterization and tint shifts.

CHOOSE RAMP

RAMP

GREY checks neutral tone steps.

RGB ramps check individual colour channels.

TIP start with GREY first.

RAMP MODE

P769

Choose linear or soft ramp behaviour.

CHOOSE MODE

MODE

LINEAR gives a direct black-to-colour ramp.

SOFT adds a darker midpoint.

TIP soft mode helps reveal shadow banding.

RAMP DIRECTION

P769

Try each direction because processing issues can vary by axis.

CHOOSE DIRECTION

DIR

HORIZ tests left-to-right ramps.

VERT tests top-to-bottom ramps.

DIAG catches diagonal processing.

START BANDING TEST

BANDING & POSTERIZATION GUIDE

P769

Banding means a smooth fade appears as visible steps or stripes.

WHAT BANDING LOOKS LIKE

Distinct bands across a gradient.

Harsh steps instead of a fade.

Blotches in dark tones.

Colour shifts on grey ramps.

COMMON CAUSES

Panel bit-depth limits.

Aggressive picture processing.

Browser or OS colour settings.

Compression-like display artifacts.

LINEAR & SOFT MODE

P769

Different ramp modes reveal different transition problems.

LINEAR MODE

Direct black-to-colour ramp.

Good first diagnostic.

Shows obvious stripes fast.

Best for comparing devices.

SOFT MODE

Adds a darker midpoint.

Useful for shadow transitions.

Reveals low-tone processing.

Good for OLED and TV checks.

MONITOR & TV SETTINGS

P769

Use consistent settings before judging whether a screen has real banding.

MONITORS

Use native resolution.

Set browser zoom to 100%.

Try standard colour mode.

Avoid extreme contrast settings.

TVS

Try PC mode or Game mode.

Disable dynamic contrast.

Reduce vivid processing.

Check SDR and HDR separately.

PHONE & LAPTOP SETTINGS

P769

Mobile and laptop displays may change output using automatic modes.

PHONES

Disable night shift filters.

Turn off extra colour boost.

Check at mid brightness.

Compare portrait and landscape.

LAPTOPS

Disable battery saver dimming.

Use normal colour profile.

Check plugged in and battery.

Avoid glare and reflections.

TROUBLESHOOTING

P769

Banding can come from hardware, settings, browser rendering or the viewing environment.

IF BANDING APPEARS

Try another browser.

Change picture mode.

Check all ramp colours.

Compare another display.

IF GREY IS TINTED

Check colour temperature.

Disable night mode.

Try standard colour profile.

Use white screen too.

FULLSCREEN & SAFETY

P769

Use comfortable brightness and avoid long static sessions.

FULLSCREEN ISSUES

Browsers need a user click.

START works without fullscreen.

FULLSCREEN may be blocked.

ESC or click exits.

SCREEN SAFETY

No flashing is used.

Avoid long max-brightness sessions.

Do not leave OLED static for hours.

Stop if uncomfortable.
