Abstract: Display of a test pattern on a liquid crystal display (“LCD”) device or other display device can expose a problem with control logic that causes perceptible shifting in color values away from correct color values. For example, a test pattern evaluation tool determines a test pattern that is based at least in part on a base pattern of pixels. The test pattern evaluation tool successively renders the test pattern for display on a display device. In doing so, the test pattern evaluation tool offsets the base pattern by a number of pixels (e.g., shifting by one pixel horizontally) between successive rendering operations at the native refresh rate of the display device, which facilitates evaluation of whether chromatic shift is induced among at least some sub-pixel display elements of the display device.
