STB INTRODUCES A FOUR MONITOR ACCELERATOR CARD

MVP4X provides Windows 3.1 acceleration that is 60 times faster than
standard VGA video.

September 10, 1993 -- Richardson, Texas - STB Systems, Inc. has announced
the release of the MVP4X graphics accelerator card. The MVP4X is a
graphics accelerator card designed to drive four monitors at the same time
by integrating four video channels versus the standard single channel. The
MVP-4X supports a full suite of Windows 3.1, OS/2 and DOS applications.

Based on four Tseng Labs ET4000-W32 video controller chips, the MVP4X
allows users to view four different monitors at the same time via four
independent video ports. Windows and OS/2 users can work in a virtual
screen environment, which provides one virtual screen across all monitors.
Windows, OS/2 and DOS users can utilize a port switching mode that permits
four different applications to run at the same time, one on each monitor.
The MVP4X is backward compatible with all existing STB MVP video cards
based on the Tseng ET4000 video controller chip.

Each video port utilizes 1 MG of fast 60 ns DRAM and its own digital analog
converter (DAC). Each monitor supported will have a maximum resolution of
1280x1024 and can provide up to 16.7 million colors at 640x480 resolution.
The MVP-4X is compatible with Industry Standard Architecture (ISA) and
Micro Channel Architecture bus types (both have VESA compatible modes). A
feature connector is included for compatibility with other windowing and
overlay cards, up to eight MVP-4X installed in one system will provide 32
separate video output signals.

The product supports applications for Microsoft Windows 3.x, Windows NT,
IBM's OS/2, Solaris, SCO ODT and Unixware.

The MVP4X will be available in limited quantities in October and is
scheduled to begin full production runs in November 1993. The suggested
retail price is $1,999.

The MVP4X offers users a choice of viewing multiple screens of information
at a higher performance level than single or four port video cards based
on the Tseng ET4000 chipset. "The MVP4X provides the right combination of
performance, color depth and acceleration for those who need to view
multiple sources of information simultaneously," said Product Manager,
Greg Martin. Martin defines the MVP4X, "...as a product of choice for
financial traders or anyone who views large amounts of information because
it provides them with four times as much information as a single channel
solution."
