Your display toolkit, ready on command
Call up the right screen test.
Launch a focused visual pattern in one step, use the arrow keys where supported, and return to the tool deck without breaking your flow.
Pointer, touch, and keyboard controls included.
01 / Test deck
One toolkit. Focused checks.
The deck is ordered for fast access: color, geometry, tonal response, then motion.
Animated and changing-brightness tools are optional. Stop if a pattern causes discomfort.
02 / Method
A fast, repeatable loop
Invoke the pattern, inspect deliberately, and cross-check before acting.

Read before judging
The browser is part of the signal chain
Zoom, compositing, device pixel ratio, and display processing can affect a rendered pattern. Treat Invoke as a visual toolkit, not laboratory instrumentation.
03 / Useful answers
Before you inspect
What keyboard controls are available?
Escape exits. Left and right arrows change colors, grid patterns, or motion speeds when those options are present.
Does the motion tool measure response time?
No. It provides a repeatable moving reference for visual comparison and does not output a millisecond measurement.
Are results sent anywhere?
No test result is generated or uploaded. The patterns and controls run in your browser.
