01 / Why it exists
Make a closer look easier
Some concerns appear on a still desktop; others show up only when an edge moves. Graywolf puts both kinds of visual reference in one direct path.
The motion tool is intentionally comparative. It does not read panel electronics, calculate response time, or certify refresh performance.
02 / What you can inspect
Nine focused visual references
Solid ColorCycle through black, white, RGB, cyan, magenta, and yellow to look for unusual bright, dark, or fixed pixels.
Black ScreenUse an uninterrupted black field to inspect possible edge glow, bleed, clouding, or uneven dark areas.
Uniformity FieldsCompare center, edges, and corners across neutral fields at several brightness levels.
Pixel GridSwitch among horizontal lines, vertical lines, a reference grid, and a checker pattern.
Sharpness TargetInspect fine text, radial lines, concentric targets, and corner detail for apparent softness or halos.
Contrast StepsCompare near-black and near-white steps to see whether adjacent tones remain distinguishable.
Grayscale RampView stepped and continuous gray ramps for abrupt jumps, tinting, clipping, or visible banding.
Color RampsInspect red, green, blue, cyan, magenta, and yellow transitions from dark to bright.
Motion TrailTrack a moving reference at three speeds to compare perceived blur, trailing, and animation smoothness.
03 / Principles
How Graywolf is designed
Two-mode thinking
Static and moving references are presented as complementary tools.
Controlled comparison
Guidance asks users to change only one setting at a time.
No invented metrics
The browser animation never claims a hardware measurement.
