Description Part Number
UX-Stretcher: Expand any DVI-D
among 4 DVI-I screens.
Includes: [UXST4, (CCPWR06)]
SmartAVI’s StretcherPro is a dynamic, real-time
video wall system that will soon have you stretching high-definition images and video over four
screens, creating a fantastic and eye-catching
presentation for your customers or clients in no
time.
This video wall system controller can take any
DVI-D source and stretch it across four VGA or DVI
screens. You will find that this device supports the
highest resolution available (1920 x 1200) for
single-link DVI-D.
As you explore StretcherPro, you will see that each
of your screens can display ¼ of a selected image in
a 2x2 format, using real-time scaling.
In addition to using your new StretcherPro to
control a four-screen display, this hardware is fully
expandable to manage as many as 128 screens,
making it the perfect solution for entry-level display
walls, all the way up to industrial deployments
(when used in conjunction with SmartAVI’s video
wall systems).

Configuration
Controlling StretcherPro
StretcherPro is controlled manually via the LCD display
screen on the front panel of the unit.
Supports Multiple DCC Tables
A DCC table is a “list” of supported resolutions that the
computer uses to communicate with the display
VFUHHQV 7KHUH DUH GLIIHUHQW '&& WDEOHV IRU 3&V YV 0DF
(as well as other hardware systems on the market).
StretcherPro is equipped to emulate each of these
tables, allowing it to work with whatever type of
computer hardware you wish to run your digital
signage from.
StretcherPro Learning Mode
SmartAVI’s StretcherPro “learns” the specifications of
any monitor connected to it. This gives the hardware
the ability to emulate the monitors even if none are

computers/routers won’t power up properly (or at all)
without the display monitors attached at all times.
StretcherPro’s capacity to learn and remember the
display monitors allows you the freedom to work on
your content management/scheduling without being
plugged in and powered up to your entire digital
signage network every time you want to make a
change or work on a new presentation.
To enter learning mode, simply hold both front panel
buttons down simultaneously for a moment and the

the unit’s learning options. When the desired learning
