Transitions should appear perfectly smooth with zero visible stripes or color blocks.
Audit your monitor's hardware color capacity with our free Color Depth Checker. Inspect physical color depth, pixel depth, maximum addressable colors, and test gradient banding smoothness directly inside your browser with complete privacy.
Open the tool to trigger automatic window.screen.colorDepth property inspection.
Inspect physical bit depth, pixel depth, and total addressable color capacity.
Observe the gradient test strips to verify smooth color rendering without posterization.
Queries window.screen.colorDepth and window.screen.pixelDepth for accurate display specs.
Features multi-channel gradients (grayscale, rainbow, theme) to detect GPU color compression.
All display tests run in local browser memory. Zero display hardware specs leave your device.
The window.screen.colorDepth property returns the bit depth of the color buffer used for displaying images, typically 24-bit (8 bits per Red, Green, Blue channel, rendering \(2^{24} = 16,777,216\) colors).
In 32-bit pixel depth environments, an extra 8-bit alpha channel is used for transparency buffering in OS compositors. Modern HDR monitors support 30-bit or 36-bit Deep Color (\(1.07\) billion colors).
Gradient banding (posterization) occurs when display pipelines crush color steps into discrete bands. Testing with CSS multi-stop linear gradients helps verify hardware color accuracy without third-party calibration software.
