Aspects to consider when constructing NEC video walls

Planning

 Source—Determination of how the video wall is going to be used and what’s going to drive the wall

needs to carefully thought out.

o What usage is this wall going to be used for? Is a computer going to drive it? A BluRay

player? Both at separate times?

 Signal—Is this going to be a digital or analog signal? Is there any conversion involved?
 Wiring—How will the signal get distributed to the wall?

o In order to utilize NEC’s TileMatrix software, every display needs to be receiving the same

signal. It’s easiest if this is done utilizing the same source as well.

o Is this a direct connection or are other factors involved here (extenders, converters, amplifiers,

etc)

 Displays—What displays are ideal for this situation?

o Higher ambient lighting would cause for higher brightness screens

 NEC offers both commercial brightness and professional brightness screens depending

on what’s necessary

o Are ultra-narrow bezel units necessary?

 NEC offers displays with active area to active area distances as low as 5.5mm

 Ventilation/Cooling—Make sure that the wall is receiving proper ventilation behind the units.

o All NEC V, P and X series displays have temperature sensors built into the units.

 There are three sensors total, aligning themselves with 2 internal fans
 These sensors are used to measure the temperatures within certain hotter parts of the

display.

 Once a sensor hits its ‘trip’ point, it triggers fans to turn on and stay on until the

temperature is under a certain threshold.

o As a rule of thumb, if an increase of 10º C is seen when a unit is installed compared to a

single stationary unit, extra active cooling needs to be added.

 Power—Make sure that there’s enough power planned into the design for all video wall components.

Receiving

 When the units are first received, be sure to notate any boxing damage

o If damage is present, be sure to take pictures of the shipping damage

 Always inspect the units when first receiving them.

o Note that the mechanical integrity of the product is not compromised.
o Be sure to plug the product in, make sure the unit turns on

 Be sure to hit the ‘hard power’ switch on the back to do this
 Notate any cracks or scratches on the front glass

o Take pictures of any damage or defect

 Contact your distributor with any DOA or damaged goods claims to start the MRA processing

Installing

 If this is going on a wall, make sure that it’s able to support to support the extra weight associated with

the screens and mounts.

o Building engineers should be able to help here. It’s almost always a good idea to support the

wall to hold the extra weight.

 If using an adjustable mounting bracket, it’s always a good idea to ‘zero’ out the adjustment range before

installing individual monitors

o This makes fine-tuning and adjustment easier when the displays start going up
