VIDEO WALLS

Spectacular video walls work better
when the image is large and clear
and not obstructed by big bezels
(the outer edge of the screen).
Screens with almost seamless bezels
are available, but these are more
expensive. Screens designed for
public display are ideal as these are
built to last, have better connections
and better warranties than screens
designed for consumer use (like your
TV at home).
For simplicity, let’s start our examples
by looking at displaying content on two
screens. Some computers have two
outputs (VGA) so you can show the same
content on two screens. On Windows
XP, in the control panel - displays, you
can select a second monitor or screen
and do one of two things. You can
extend the desktop so that the image
is spread across both your computer
screen and the second screen, or you
can duplicate the image you see on your
computer screen, so that it appears on
the second screen.
Obviously, this only allows you to show
the same content on both screens. When
you want to display content on four
screens you need a 4-port graphics card,
or two 2-port graphics cards or you can
use a splitter box, which splits the signal.
Video walls
and content
Introducing video walls for
schools and higher education
A video wall is simply a bank of screens onto which you display content,
either on single screens or expand the content across the whole wall. Video
walls can be 2x2 (4 screen panels) up to a 10x10 video wall.
Examples of video walls - left to right: Sharp thin bezel screens, Mitsubishi LCD large format displays, NEC X463UN thin bezel large format displays
A 2x2 video wall,comprising 4 screens, in
a reception area is an ideal starting point
for education.
Manufacturers such as CYP, LG,
Mitsubishi, NEC, Panasonic, Samsung,
Sharp and Sony have large format display
screens suitable for video walls. These
range from 2x2 video wall up to a 10x10
video wall.
Depending on make and model, the
size of the bezels vary. Some screens
have option slots to slide in a built-in
PC. Some allow you to daisy chain the
screens together so you can easily add
more screens to your video wall at a
future date. Screens range from WXGA
to 1920x1080 Full HD (high definition)
resolution.
I’m considering a 2x2 video wall in my
reception area to display PowerPoint
or images. What do I need?
As an example, let’s assume you want a
2x2 video wall in your reception area, to
display a PowerPoint presentation.
Some screen manufacturers offer a
complete video wall solution which
includes all you need in the way of
screens, wall mounts and splitters.
CYP’s complete 2x2 video wall system,
for example, has four 42-inch diagonal
LED screens, four wall mounts, one
HDMI 4-way splitter box and one IR
(infrared) remote control.
