“The latest update to the Accelerated-X Multihead product
adds support for the DualHead version of the Matrox G400 graphics
board. Several versions of the G400 exist; the DualHead
version has two monitor connections. Other versions of the Matrox
G400 have only a single display connector and are not supported by
this update.
“The Multihead support for the G400 DualHead is in the form of a
Single Logical Screen (SLS). The entire screen area of both screens
is presented as a single drawing area, so that windows can overlap
two screens…”
“The update is now freely available to users of the
Accelerated-X 5 Multihead product (MX) from the Anon-FTP
site…”
