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.
