This article describes methods of testing monitors by allowing a viewer to see line distortion and/or color distortion if it is present in the monitor. The designers of color monitors use instruments and mathematics to determine the distortion specifications of their systems. The refinement of these specifications can be pushed with greater cost, but there is currently no information as to when cost effectiveness declines. In other words, knowing at what point any decrease in color distortion would not be appreciated by viewers, designers need not over-specify this particular dimension. Therefore, this disclosure presents a method of testing monitors for line and color distortion as can be observed with the unaided eye. The patterns disclosed herein have two purposes.
