1. s almost always a good idea to support the wall to hold the extra weight e 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 e Be sure to have at least two people per screen when mounting them on the wall or stand o NEC displays have support handles that are built specifically for the handling of these fragile units Be sure to utilize the support handles when carrying the product o Do not grip or carry the display directly by the bezel this can cause unnecessary Strain on the edges of the panel itself and could possibly crack the glass e If it s necessary to set the product down do so in the face up position on a cleared padded surface o Never set any of the Ultra Narrow bezel screens on their sides or on their corners this could damage the structure of the panel e NEC recommends that a business card is able to slip between all displays on all sides during the installation process o Due to thermal expansion screens can slightly expand Allowing extra space initially will help in avoiding unnecessary strain on the bezel TileMatrix Setup e Each NEC V P and X series screen has TileMatrix EEEa TAr LE MATRIX technology built into each screen In order to utilize 1 MONITOR r e seule k 1 IU TileMatrix each screen needs to receive the same zj MONIT2.

3. NJ EC NEC Display Solutions of America Inc P Aspects to consider when constructing NEC video walls lannin 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 lIs 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 Example of Daisy Chain OUT a ae Pavers Example of Distribution Amplifier e 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 e Ventilation Cooling Make sure that the wall is receiving proper v
4. entilation 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 Asa rule of thumb if an increase of 10 C is seen when a unit is installed compared to a single stationary unit extra active cooling needs to be added e Power Make sure that there s enough power planned into the design for all video wall components Receiving e 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 e 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 e Contact your distributor with any DOA or damaged goods claims to start the MRA processing Installing e 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
