The contents of the package are what we would expect of a value
solution. Included in the package are a half-height PCI
bracket, a DVI-HDMI converter, a DVI-VGA converter, TV-out to RCA
converter, and Installation CD with drivers. The half-height
PCI bracket allows a user to install in a slim box, however, you
lose access to the second monitor out with it installed.
