# 1680x1050 :: Script to force 1680x1050 on VGA1 connector
#
# This script is useful when the VGA output of the video card is
# connected to a splitter, which is then connected to a video monitor
# and a projector (which is the case in most of the electronic classrooms
# at Seneca). The splitter prevents the EDID from being probed by DDC, so
# the system does not know the available resolutions, and picks a low-res
# (safe) mode. This script forces 1680x1050 resolution -- be sure that
# the LCD and projector can both handle this resolution before running
# this script. It is known to work in most of the TEL-building classrooms
# as of Fall 2010 on Fedora 13.
