such as broadcasters and food retailers where color accuracy and esh tones are critical.

Tiling Capability with Frame co mpensation Page 39
Up to 25 panels (5 wide x 5 high) can be combined to create a single large image (i.e., video wall) or oth er high-im pa ct signage. A
fram e compesation function i s i ncorporated to compensate the width of panel bezels so that images are displayed with the utmost
accuracy.

PiP, PoP and Side-by-side Pages 37 and 43
Picture-in-Picture and Pic ture- out-of-Picture are available when you want to display video c ontent from a video input source in the
sub picture and display the PC input source in the main picture, and vi ce versa.

x can displ ay these two input sources in the Side-by-si de mode, ideal for broadcastin g

and video-confer encing appli cations.

Programmable Scheduling F unction Pages 28, 29 and 38
The monitor s operating schedule can be programmed for up to seven different sc heduled time intervals by time, day of the week
and input port. This allows video content from different inputs to be displayed on certain monito rs within the same installation
ac cording to the sc hedule, and extends the mo nitor s life and saves the power by turning it off during those hours or days it i

s n ot in

use.

To avoid the monitor from falling
When installing the mo nitor using the tabletop stands (o ptional),
take measures to prevent the monitor from falling over in case

CAUTION:
The effect of the fall prevention substa ntially depends

on the strength of brackets and base to which the fall
prevention dev ices is attached. When you cannot ensure
suf

Though the recommen ded fall prevention is intended to

lessen the probability of injury a nd dama ge, it doesn t
assure its effectiveness against any kind of earthquake or
disaster.

Do not sleep where the monitor may topple o ver or fall in

case of an earthquake or other disaster.
