Moving Inversion Patterns
Moving Inversion Patterns

Instructions: This is a test for LCD monitors for inversion artifacts. (e.g. fine checkerboard pixel patterns, color distortions)
Prerequisites: LCD being tested in landscape mode, not portrait mode, using 1:1 pixel mapping, no browser zooming.
Inversion artifacts are common on many models of 120Hz and 144Hz LCD's, and the appearance of inversion can be amplified during strobe mode (3D mode, LightBoost mode, etc). LCD inversion is the alternating positive/negative voltages used within an LCD panel.
Scientific Explanation: For more information about LCD inversion, see Lagom Pixel-Walk and Techmind Inversion Article.
