I read this from
For 4.0.0 and later versions of XFree86, you no longer have to generate
modelines at all. Instead they are computed internally by the server at
based on the resolution you specify in the Modes part of the Screen
section part of your XFree86 configuration file and the monitor
capabilities your X server
gets via an EDID query to the monitor.
To change your screen resolution and color depth, simply edit or create
a Display section describing it.
All you will usually need to do is change the numbers in the Mode entry.
X will do the rest. If you specify an impossible resolution, it will
fall back to the closest
approximation that the EDID data from the monitor says it can support.
Therefore, the information in the remainder of this HOWTO is useful only
if (a) you have an old, pre-EDID monitor, or (b) your graphics-card
support querying the monitor, or (c) you are running an old version of
XFree86 (in which case, you should fix your problem by upgrading), or
monitor/card combination can support a resolution above 1920 x 1440,
which is the maximum XFree86 supports in a canned modeline.
I'm running Redhat 7.1 with a Matrox G550.........
any thoughts would be appreciated (I DO NOT want to blow up the
plasma...that would be very bad!!) :-)
