Abstract
Methods, systems and apparatus for generating test patterns for selecting a transfer function of a display device. A method includes generating multiple simulated transfer functions for a display device, rendering multiple patterns of anti-aliased parallel lines on the display device, each pattern rendered according to a corresponding one of the simulated transfer functions and including off-vertical lines and off-horizontal lines, receiving an input from a user of the display device selecting one of the patterns rendered on the display device and setting a transfer function for the display device to the simulated transfer function representing the selected pattern, the transfer function characterizing a relationship between an applied input voltage and an output luminance for any given pixel on the display device.
