A wall is built from an array of physically separate display devices. To obtain the best results,
mechanical and electrical alignment must be performed to ensure that the images in the separate
displays are accurately aligned. This section deals with the alignment aids that the
MediaWall V 4K/
UHD Display Processor
provides.
1.
Mechanical Alignment
It is extremely important to perform mechanical alignment prior to making any electrical
adjustments. Make sure that the individual display devices are rigidly mounted or the wall will
quickly go out of adjustment, or alignment may not be possible at all.
2.
Display adjustment for wall displays
Each display device has adjustments for the size and position of the image on the display
screen. Follow the manufacturer’s instructions for best results. Because each display device
has its own controls for size and position, these controls are not duplicated by the
MediaWall
V 4K/UHD Display Processor
. Note that color adjustments can be made at a later time
following wall alignment.
Typically there is a small frame, called a
mullion
, around the active display area of each display
device. This represents dead area in the wall and must be compensated to avoid geometric
distortion of the full image. Mullions are most often used with displays having a bezel surrounding
the display area.

area. Note the dislocation error or offset in diagonal lines crossing mullions between cubes.
