NEX-series Video wall
GPO Display’s video wall displays have a built-in video wall processor that allows for virtually any matrix size of LCD video wall. In this
manual, instructions for a 2x2 configuration will be used as an example.
1. Installation
To install NEX Series displays in video wall configuration, please read the installation directions carefully before installation is performed.
These monitors can be installed for single display/”standalone” operation, in a single row, or in multiple rows. The highest Display Sequence
number is 99. Contact GPO Display for arrays comprised of more than 99 displays.
CAUTION
: Never connect or disconnect cables from the display when the display is powered on as this may cause serious
damage.
2. Installation Requirement
2.1 Structure for the installation
Support structure design and construction for the display installation is the customer’s or its installer’s responsibility. GPO Display does
not take any responsibility on design or construction of installations. The minimum requirements for space, strength of the structure,
electronic, heat dissipation and environmental condition is described in the following. If any further information or support is needed
from GPO Display, please contact us in advance to ensure ample time for support. We will be glad to help with any recommendations or
information. Call 510-659-9855 or e-mail
2.2 Power Requirements
Please refer to the specifications for power consumption of displays to be installed (Page 4)
Do not plug more than two units into a given receptacle (example: all displays in 2x2 should not be plugged into quad receptacle
Using more than 70% of current on the AC circuit is strongly discouraged. Clean AC power is required for “noiseless” screen images.
Avoid damages inflicted by power glitches or surges- either a power conditioner or surge protector is recommended. Contact your
electric power specialist for consultation.
3. Heat Dissipation
Recommended LCD operational conditions are:
Temperature: 32
°
F -104
°
F Humidity: 20-80%

. General Information
1.1 PC Settings:
PC’s need to be set to an appropriate graphics mode that has the same resolution with the panel to have clear screen image. And
the vertical refresh rate should be set to 56~75Hz, non–interlaced signal. The controller has been designed to take a very wide
range of input signals however to optimize the PC’s graphic performance we recommend choosing 60Hz vertical refresh rate: this will
prevent screen flicker. If you wish to view 4k2k@60Hz resolution, must use the PC that supported HDMI 2.0 (or DisplayPort 1.2).
1.2 Signal Quality:
Signal quality is very important: If there is noise or instability in the PC graphics output, this may result in visible noise on the
display. Refer to the graphic modes table in specification section for supported modes. Non-interlaced & interlaced video input is
acceptable. Please use the HDMI 2.0 or DisplayPort 1.2 dedicated cable. (4K2K@60Hz)
