[AG-TECH] video only shows on primary display

[Allan Spale]

Chris,

That is one of the things that I do not like about the display setup for
the G450.  It seems to treat two displays as one logical display.  If you
find a workaround for this (where each individual display appears as
itself in Display Properties), please let me know.
