Videowall Design Considerations for Now and in the Future

Videowall Design Considerations for Now and in the FutureWith videowalls gaining more popularity than ever, system integrators have more opportunities to use this technology in different configurations.  Even if the displays are individually placed across multiple locations the effect of impressions is still great as it’s easy to control many more installations over the LAN.  Modern mounting systems even allow for multiple videowalls of different sizes used along with single monitors distributed throughout a facility.

The design considerations are pretty basic.  You will need displays, media players, a mounting system, a content delivery and control system and the communication infrastructure.

Although it may be tempting to use consumer grade displays for single monitor locations, they are not means to run for extended periods.  Commercial grade flat panels can run from 16 to 24 hours a day and can be mounted vertically or horizontally for more design freedom. Commercial monitors also have the option for IR remote lockout and RS232 control capability.

Sometimes a short throw projector for rear-projection can even be a more appropriate solution for a big message that has a small budget.  If there is more continuity of the message without the worry how tightly the monitor bezels will line up, then rear projection is the answer.

Media Players
This is really nothing more than a PC.  Special players in the size of a paperback book can be installed directly behind the monitor lessening the need for extenders.  Some monitors even come with onboard computers.

Mounting Systems
Videowalls should use mounting systems specifically built for tiling displays.  These systems line up perfectly so the resulting message is continuous since they allow for micro-adjustments.  The human eye can easily pick up on misalignment so it’s important to have everything in line.  Mounting systems are now offered in so many different configurations from free standing to suspended.

Control System
Delivering the content is a high priority and the latest control systems use smart devices connected by a regular Ethernet network.  This eliminates the switches and video processors.  Being able to connect monitors that are not close together via Cat5e or Cat6 cable comes at a much lower costs while able to go for long distances versus regular AV cables.

With technology and lower prices meeting in the middle, it’s expected that videowalls will grow 400% over the next few years.  For this reason, it would be wise to understand all the options to know what a videowall system is capable of and also how much it costs to deploy now and over time.
