Planning and Conguring a Wall Layout

Planning

Careful planning prior to installing, wiring, and conguring a video wall will help streamline the process. This chapter

provides some insight into different congurations and the amount of time required to successfully calibrate a video wall.

In order for the software to uniquely identify and communicate with each display, the following conguration settings

must be made:

• The number of rows and columns of displays in the video wall.

• The communications interface type for each display (RS232 or LAN).

• How the displays are connected to the host PC, and to each other.

• The Monitor ID of each display.

• The order in which displays are assigned IP addresses and Monitor IDs.

Note: NEC Display Wall Calibrator includes a Layout Wizard which greatly assists in planning the conguration and

connections of a video wall. This feature can be used for planning purposes even before any hardware is installed in order to

determine the optimal conguration for smooth deployment, conguration and calibration. See “Conguring a Layout with

the Layout Wizard” on page 30 for more information.

Physical Considerations

For large video walls where it is necessary to use a ladder or platform to access the screen of each display, careful

consideration should be made of the layout order in order to minimize physical movement and in turn maximize the

efciency and speed of the calibration process.

For example, if using a ladder, it may be easier to calibrate a vertical column of displays, and then move the ladder

across to the next column. Similarly if using a horizontal platform, it may be easier to calibrate a horizontal row of

displays, and then move the platform up or down to the next row.

For very large video walls, for example larger than a 5x5, it may be more efcient to split the calibration into two separate

projects and divide the wall into two. However keep in mind that depending on the calibration Target type being used, it

may be necessary to measure all of the displays in the video wall in order to determine the dimmest display.

For video walls that use LAN based daisy-chaining and use the Auto ID function, the Monitor IDs are assigned based on

the physical wiring connection order from the rst display. So the connection order of the LAN cables between displays

is an important consideration.

Note: The calibration order for existing video wall congurations can be changed at any time using the “Calibration Order” on

page 37.
