document: Full-screen ultrafast video modes over-clocked by simple VESA routines and registers reprogramming under MS-DOS Fast full-screen presentation of stimuli is necessary in psychological research . Although Spitczok von Brisinski -LRB- 1994 -RRB- introduced a method that achieved ultrafast display by reprogramming the registers , he could not produce an acceptable full-screen display . In this report , the author introduces a new method combining VESA routine calling with register reprogramming that can yield a display at 640 * 480 resolution , with a refresh rate of about 150 Hz
