A method and device for increasing the horizontal resolution of both a color flat panel display and a cathode ray tube (CRT) display. The method involves fine horizontal positioning of pixels according to information encoded in the color. Since pixel size is not changed, the display and processing bandwidth requirement is not increased. For the case of the color flat panel display, the fact that each pixel is constructed of a horizontal stripe of 3 primary color sub-pixels is utilized. Complex color information is spread across adjacent pixels to increase the apparent horizontal resolution by a factor of three. For the case of the CRT, a clock multiplier is used to multiply the video clock frequency by three. The apparent horizontal resolution of the CRT is increased by a factor of three by delaying pixels a varying multiple of this high clock speed. By encoding the fine repositioning information in the pixel color, the same display output can be post-processed respectively for the color flat panel and the CRT, allowing them to be driven and resolution enhanced simultaneously.
