=============================== WARNING ===============================
There is no support for your monitor in the database, but ddccontrol is
using a basic generic profile. Many controls will not be supported, and
some controls may not work as expected.
Please update ddccontrol-db, or, if you are already using the latest
version, please send the output of the following command to
ddccontrol-users@lists.sourceforge.net:

LANG= LC_ALL= ddccontrol -p -c -d

Thank you.
