It is important to realize that monitors are auto-detected by DDC 
probing the monitor.  If the software gets a response from the 
probe, then the monitor is successfully autodetected and can be 
configured with the settings that the monitor provided.

The monitor hardware database is not required for autodetection 
at all, and no monitor entry needs to be present for a monitor to 
work with XFree86 properly.

The monitor database is there for 3 reasons only:

1) To list monitors that do not support DDC at all, and need to 
   have their entries there so the user can manually choose them 
   from a list.

2) To allow the user to pick the monitor from a list if DDC 
   probing does not work for any reason including the video card 
   or monitor not supporting DDC, or the video driver not 
   supporting DDC, or if a KVM switch or other device interferes 
   with the DDC signal, or if the monitor is powered off during 
   DDC probing.  There are other potential reasons why DDC 
   probing may fail as well.

3) To override the settings returned by a given monitor model 
   when they are known to be incorrect due to the manufacturer 
   shipping defective hardware.  Yes, this happens.  ;o(


So if DDC _can_ probe your display and it works, there's no need 
to have the display listed in the database for you to use it per 
se.

Nonetheless, we don't mind adding any new displays to the 
database.  All you have to do, is attach Microsoft Windows .INF 
files supplied by the monitor manufacturer into a bugzilla bug 
report that requests the entries be added to the database.  Feel 
free to attach all .INF files for all monitors of a given brand, 
or of as many brands as you like, and they'll all get processed 
simultaneously.


Hope this helps.
