Definition List
This page will explain what the abreviations
in the table that I had you draw for the High Res NHF.
Name: This parameter is actually
the "name" that other parts of the XF86Config file looks
for to get the necesary data to be able to draw X-Windows
properly on your monitor.
dot: This parameter is actually
the "dot clock" or the "Pixel Clock" that will be used to
display the image on your monitor. It is the frequency,
in megahertz (MHz), at which your video card can draw pixels.
For example, if your video cards maximum "pixel clock" is
230MHz then at that frequency your video card is capable
of drawing 230,000,000 pixels per second.
hor: This parameter is the
horizontal number of pixels to be draw onto your display.
hore: This parameter is the
actual number of pixels per horizontal scan line needed
to draw "hor" onto your monitor, and it is always approximately
1.25 times larger that "hor". Meaning "hor" equals 0.8 times
"hore". This ratio can vary somewhat. So, it is ok if your
"hor" equals 0.75 times "hore". However it shouldn't be
more than 0.8.
vert: This parameter is the
number of horizontal lines to be drawn on your monitor vertically.
verte: This parameter is the
actual number of horizontal lines stacked vertically needed
to draw "vert" onto your monitor.
sys: This parameter is the
start of the sync pulse. For "hor", it should be no less
that 32 + "hor". For the "vert", "sys" you usually want
it to be within 3 + "vert".
sye: This parameter is the
end of the sync pule. For "hor", it should be be at least
32 - "hore". For "vert", "sye" is usually within 6 + "hor".
