Overview

Display Patterns helps uncover issues that may not be obvious on normal content, including banding, uniformity problems, and image retention.

Viewing A Pattern Full Screen

When a pattern is shown full-screen:

• Tap the screen to exit.
• A short hint overlay appears briefly when the pattern opens.

Pattern Info

Many patterns include an Info button. The info sheet includes a short description and, for some patterns, a Wikipedia link.

Available Patterns

Based on the current app source, patterns include:

• Solid colors: White, Black, Red, Green, Blue
• Checkerboard
• SMPTE color bars
• EBU color bars
• Multiburst
• PM5544
• HDR Test Pattern
• HDR-Style SDR

Notes And Limitations

• The HDR Test Pattern temporarily forces maximum brightness, disables auto-lock, and enables EDR where available. These settings are restored when you exit the pattern.
• Some patterns can reveal PWM flicker sensitivity; results can vary by brightness.

What You Can Do

• Show gradients to spot banding and tinting
• Show grids/lines to spot distortion and scaling artifacts
• Show high-contrast patterns to spot flicker or image persistence

Notes

• Some patterns may reveal PWM flicker sensitivity; results can vary with brightness.
• View in a dim environment to better see subtle banding.
