Chester F Bassetti, Mangesh S Pimpalkhare, Krishnan C Dharmarajan: EMI reduction for a flat-panel display controller using horizontal-line based spread spectrum. NeoMagic, Stuart T Auvinen, May 26, 1998: US05757338 (35 worldwide citation)

A graphics controller uses spread-spectrum techniques to modulate the pixel clock over a range of frequencies, reducing the maximum intensity of EMI emissions. When the clock input to the graphics controller is replaced with a modulated clock, the image on a CRT is distorted. Distortion is avoided b ...
