Display Tests
Inspect pixels, uniformity, gradients, contrast, and motion on your screen.
Dead Pixel Test
Run full-screen solid color panels to find stuck pixels, dead pixels, and uneven display defects.
Backlight Bleed Test
Inspect black-screen backlight bleed, IPS glow, corner leakage, and panel edge brightness.
Screen Uniformity Test
Check monitor uniformity with white, gray, and near-black panel grids sized for full-screen inspection.
Monitor Color Test
View RGB, CMY, grayscale, and saturation bars for browser-based display color checks.
Refresh Rate Test
Estimate display refresh rate and frame pacing through browser animation timing.
Motion Blur Test
Inspect ghosting, overshoot, and motion clarity with a moving display target.
Contrast Test
Check monitor contrast visibility using stepped dark-to-light reference blocks.
Black Level Test
Evaluate shadow detail, black crush, and near-black separation on your display.
Gradient Banding Test
Inspect smooth gradients for banding, color stepping, and compression artifacts.
Before you begin
Patterns provide visual references for your own inspection. Refresh estimates come from animation callbacks, not direct panel telemetry. Lighting, display processing, viewing angle, and browser behavior affect results.
