7 CONSIDERATIONS WHEN MOUNTING A VIDEO WALL
The videowall has become the ideal platform for providing a ‘wow’ factor in terms of showing content to the public especially in the retail industry. It is equally at home where a large screen area is required to be seen by an audience. The advantage over a large screen alternative is cost and because screens can be used in daylight they tend to outperform projectors. The downside of using a videowall made up of separate displays is that there will be a grid of screen bezels that can be seen in the content Therefore, all methods of showing content to an audience should be investigated before deciding on the method of display.
It is assumed you have chosen to install a videowall using LED backlit LCD screens and that you will be using one of the popular sizes, 46inch or 55inch. Screen manufacturers have models that are made specifically for videowall use in these sizes that have narrow bezels along with software to link screens together.
So here are the considerations to help you to successfully install a videowall:
- There are potentially 3 ways of installing a videowall; direct to a wall, suspended from a ceiling or floor mounted. Therefore each location should be assessed carefully for structural robustness. According to BS8590 (2014) the fixing area must be capable of supporting 5 times the load.
- The ambient light will affect the perceived brightness of the screen output so if a videowall is to be placed near a window in direct sunlight it may be advisable to use high bright screens. These screens run hotter than normal screens, so depending on location there may be the need for extra ventilation.
- Whilst videowall screens have thin bezels, which make a thin frame around the whole wall, many customers want a more substantial frame around the wall or to inset the videowall into a false wall. It is therefore paramount that there is enough ventilation and room for maintenance built in to any structure.
- Once the site and method of installation has been chosen the type of mounting system should be finalised. The most common way of mounting a videowall is to use a pop-out videowall mount for each screen fixed to a wall. A pop-out videowall mount allows each screen to be adjusted in all three planes in relation to its neighbouring screen then pushed in to its installed position until screen maintenance or swap-out.
- Where no wall is present then ceiling suspension is another method of installing a videowall. This method of installation requires a substantial structure to be fixed to a ceiling capable of supporting 5 times the load of the structure including videowall mounts and screens. Due to the offset fixing position into the ceiling in relation to the videowall TV screens there is a horizontal load acting to push the wall back from the perpendicular. To prevent the wall leaning backwards the structure supporting the videowall mounts has to be stiff.
- The last method of installing a videowall is to have it floor mounted. The higher the videowall the more it will lean forward, which has to be balanced by the length of floor base along the front of the wall. In many retail environments, where floor space is a premium, having a base unit protruding from the bottom of the wall is unacceptable. If this is the case the resulting unstable position can be solved by bolting the structure into the floor or adding weights to the rear of the structure.
- A method of installing a videowall that provides versatility in a retail environment is to use a bolt down structure that can roll forwards and backwards on extendable tracks. Once the wall is in position the extendable parts of the tracks can be removed to minimise the videowall footprint area. This method allows a videowall to be pushed up against a window in normal use then pulled back for cleaning or pushed back against a wall for normal use and pulled forwards for maintenance.
Unicol has been making videowall mounts, ceiling suspension, freestanding, floor fixed and rolling videowall mounting solutions for many years and all solutions use a pop-out videowall mount with adjustment in all planes. There is a team of experts at Unicol to guide anyone wanting to install a videowall in any market and in most indoor environments.
