Video Wall Components
When you see video walls displaying eye-catching content, many people will take for granted the precision and work behind the scenes required to get it up and running. Video walls can be as simple or as advanced as you need them to be; however you need a professional to ensure the correct solution is utilised.
There are a number of video wall components that you must choose in order to make sure your installation works seamlessly. Here is a quick look at the essential components of a video wall installation.
Mounting your video wall is hugely important as it is what holds up your precious screens, making sure they don’t fall to the floor. The type of mount that you go for will depend on the size of your video wall, it will also depend on how you wish to mount the screens i.e. ceiling mounted video wall / a video wall mounted in the window of your retail frontage / a video wall mounted on a wall at high level etc.
- Framework bracket – mount flat against wall: this is an entry-level bracket and will save you money in upfront hardware costs but will add cost to your video wall with installation and maintenance if used for larger video walls.
- Pop-in, pop-out bracket – allows screens to easily be accessed from behind: this is the premium and preferred solution as it allows for exact installations with ease, ensuring maintenance issues are readily accessible.
- Drawstring release bracket – similar to ‘pop’ brackets: offers similar quality and serviceability however, we have noticed difficulties during maintenance if the screens are in a recess and the drawstring is not accessible.
- Ceiling/floor – mounted to either floor or ceiling or both, via a pole and bracket solution: perfect for unique installations and we recommend using for retail shop windows with a roller track to allow for easy install and maintenance as well as being able to get the video wall as close to the window as possible to limit any glare.
- Universal wall bracket – flat to wall: this is not recommended and is only used when installing single screens. This will be extremely time consuming to install and very laborious to maintain.
When choosing screens, you have to consider several things that will influence your choice.
Bezel width: the bezel is the area surrounding a screen that doesn’t display content. Video walls with multiple screens displaying one image should have a small bezel width to prevent the display from appearing broken up. Over the last year, LG and Samsung have both released their slimmest bezel screens offering almost zero gap between screens (approx. 1mm).
Brightness: there are bespoke offerings from Dynascan for High Brightness installations. These are the best solution when going into a high ambient light location such as a window display on the highstreet. High brightness screens are often used for retailer video wall or for an estate agent’s video wall. If the video wall is in a shop window, it should always be high brightness.
Budget: technology in this industry is rapidly developing and thinner screens with a cleaner, better quality display seem to be churned out every year. Generally, the more you have to spend, the slimmer and more advanced the screen will be. If you do not need ultra slim bezels or a high bright screen there are much more affordable screens on the market, meaning you can still get a high impact video wall installation without unnecessarily breaking the bank.
This technology is responsible for what is displayed once the screen has been attached to the bracket. If you want to display one image across the entire video wall, or if you want to display multiple sources you will require a video wall processor.
When using multiple inputs across your video wall, Datapath/Matrox video wall controllers allow the user to control the input into the screens of any size in almost any layout. For some simpler installations, the screens have a video pass through technology that can be taken advantage of to display a single image/video across all screens (depending on the content and the layout of the screens). Management of content distribution can even be taken care of by installing the standard software onto a control station, or a Crestron control processor could be integrated to offer a bespoke control interface via iPad or other devices.
Installing the Video Wall
Once you know the video wall components that will best suit your requirements, you have to put them all together…or as we recommend, get an AV integrator to do it for you, and who better to choose than MVS!
