Is it possible to program a Tseng ET-4000 based SuperVGA card (or other
SVGA) to operate at higher refresh rate than normally. For example if the
card can operate at about 50 kHz line frequency and I want 90 - 100 Hz
frame rate at 640x480 resolution. My monitor will sync to these rates. I
have not yet bought any card and want to know if there is such  ones which
can operate noninterlaced at vertical frequence in range 80-150 or up or
interlaced at least 120 Hz.
