Video walls
Video walls
Plasma screens or large LCD monitors can be connected together to display a single image as a video wall. You then have the option of:
Displaying a huge single image between all the screens on the wall
Displaying the same image on all the component screens
Displaying a different image on each screen
You will need a control box to connect all the screens together. Some plasma screens also come with the hardware to do this built-in, so that you can connect several of them together as an instant video wall. You will need a wall mount bracket for each screen and its worth checking whether the manufacturers plasma screens you are considering purchasing, use a standard wall bracket or a specialist video wall bracket,
for example NEC, that allow the plasma screens to slide out for replacement or maintenance without dismantling the whole wall, as the price of these special brackets are much dearer than standard wall brackets. You can buy 2, 4, 9, 12 or 16 screen mounting brackets to connect screens together
for a video wall.
The links below give comparisons on plasma, LCD monitors, plasma screen
mounts, video wall mounts, manufacturer specific mounts and digital
signage with our review of software packages.
Video wall mounts
The problem with a plasma or widescreen LCD monitor video wall is that there is an inch or more gap (bezel) between screens. Orion make
Neodigm 84-inch plasma screen, which is actually 4 x 42-inch screens connected together with a very small gap between
screens. They also make Infinite modular panels for wall mounting or on a
stand, allowing all kinds of configurations for many applications. Orion
plasma screens. This gives a better overall video wall effect, but obviously the cost of both options including all bracketry and any computer graphics cards, needs to be taken into consideration.
Please see our section on manufacture mounts for details. Manufacturer
specific mounts
UK bracket manufacturers produce wall mounts for video walls. Often these
are less expensive than the screen manufacturers own mounts, although of
course you would have to dismantle parts of your video wall if you wanted
to replace a screen. Video wall

Digital signage
Another consideration is what you want to show on your video walls. As
most of the plasma screens and LCD monitors tend to be for corporate use,
speakers are not normally in-built, neither do they have a TV tuner, so if
you wanted to show sports on TV then you would need to have have the
appropriate inputs on your screens. A fashion show in a retail
store, for example, would probably not need sound. Digital
signage
You might want to convey your message via a digital signage software
package. Samsung,for instance include MagicInfo built-in
digital signage software with some of the LCD monitors, which are built
for 24/7 use and include coolers to stop overheating. They can be built
into video walls. Other manufacturers, such as NEC, nclude a Text Ticker
feature in some of their corporate
plasma screens,i which allows messages to be
run across the bottom of the screen, much like you see football results
displayed on your TV. NEC also make large LCD monitors in
portrait or landscape modes, as do Sharp.
Professional digital signage software packages are available, as are
servers and players for pushing content to screens 24/7, even
worldwide if you use the Internet. Once you know what you want to produce
you can then find a package best suited to your needs.
Even though plasma screens are less likely to suffer from plasma burn,
(where a static image burns into the screen) if you are using digital
signage banners to run across your screen, even though the moving part of
the banner would be fine, you can still get plasma burn caused by the
outline of the banner. You can buy plasma screens which include a
plasma burn protection features. Some digital signage software allows you keep
banner borders moving to reduce plasma burn. This kind of problem does not normally occur
with LCD monitors.

Installation
We highly recommend that you use local knowledgable installation engineers or we can obtain quotes for you from a third party manufacturers authorised installation company, where possible, to set up your video wall. All installation costs are subject to site survey. Cabling is not included in the video walls and costs extra, usually supplied and costed by installation companies. It may be necessary for additional signal distributor to be purchased (extra cost), depending on manufacturers video wall and site installation.
Please also bear in mind that plasma screens are heavy, and will require
more than one person to move them to the installation
site. It is also advisable that plasma screens are
checked to be in fully working order prior to installation, as we cannot
accept responsibility for damaged screens after 24 hours from delivery;
otherwise manufacturers warranty comes into effect and excludes
damage.
