GETFREQ.EXE DOCUMENTATION
This program give only the vertical frequency of the display adapter.
Useful only for programmers who want to be aware of a such question.
Type /? on command line for immidiate help.
Option /D on the command line has to effect to do not clear the screen
while testing. If the screen is not clear while testing(option /D), the
result may be wrong on certain SVGA cards. For those who use the vertical
retrace tricks in their program, may be aware of the result given by this
program to know if their video card works well with vertical retrace bits.
Because on certain SVGA card, testing the vertical retrace must be done
when the screen is empty, otherwise the detection is not done correctly.
Source code is written in DASH, so I suppose that anybody can compile it
because the DASH has been created by myself and it is not on the market.
