Abstract:
1. A method of communicating digital data from a computer system to a display device comprising: receiving and processing an analog video signal from a computer system via receiver means for receiving and processing analog video signals, wherein the receiver means for receiving and processing includes a mode detection circuit, a processing circuit, a tuning circuit, a phase lock loop (PLL), and an analog-to-digital converter; sampling the analog video signal to provide digital data; performing compensation of the digital data including modifying data via means for scaling to compensate for differences in spatial and color resolution between the analog video signal and requirements of the display device; detecting a predetermined data pattern from the digital data, wherein the predetermined data pattern corresponds to a frequency or resolution parameter of the analog signal; and in response to detection of the predetermined data pattern, commencing a set-up process for converting a video signal into a display image of improved format for display on the display device, wherein the set-up process includes: wherein the improved format enables more accurate display of original image data.
