Instructions

www.gpodisplay.com DN46HE
To ensure safety, please read this manual carefully before installation and follow the instructions
herein. Store this installation guide in a secure place for future reference.
• The Virtual Skylight Display must be installed on a flat and level surface which is strong enough to
bear its weight.
• Make sure mounting brackets are tightened and secured on the wall
• The Liquid Crystal Display (LCD) panel of the display has a very thin protective layer of coating
which is susceptible to marking or scratching, and cracking if struck or pressured. Please cover and
protect the displays if there is construction or other work being conducted at the installation site.
• Transport and handle displays by holding the handles on the back of the display. Do not touch the
LCD panel surface directly to avoid possible scratches and backlight leakage
Notes on handling/transporting displays:
LCD Virtual Skylight Display has limited mechanical strength. To prevent the display from
performance failure caused by line defects, front bezel bending, glass scratch/broken, light leakage,
etc, it must be handled with care.
• Always move the display by at least two (2) adults.
• Retain the original shipping box and packaging in storage for use in the future, when you may need
to transport the product.
• When placing the display face (panel side) down:
-Prepare a flat, level, horizontal surface that is larger than the display and spread a thick protective
sheet/foam on it. (Fig. 1) –Lay the display down gently and horizontally.
• When you want to place the display in an upright position:
-Lift the display up horizontally by holding the two (2) handles at the top/rear with one hand per
person and supporting the bottom bezel with the remaining hand. Do not allow the display to
rest/put weight on bezel edges and corners
-Be careful not to scratch any parts of the display when placing the display upright. (Fig. 3)
-Stand the display vertically to make sure the its weight spread evenly throughout the bottom bezel.
* Do not rest on corners or lean forward/back. (Fig.4)

GPO Display’s Virtual Skylight Displays have a built-in video wall processor that allows for virtually any matrix size of LCD Virtual Skylight
Display. In this manual, instructions for a 2x2 configuration will be used as an example.
1. Installation
To install DN46HE displays in Virtual Skylight Display 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 cable to the display when the display is powered on as this may cause serious damage.
2. Installation Requirement
2.1 Structure for the installation
The 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 [e-mail].
2.2 Power Requirements
Please refer to the specifications for power consumption of displays to be installed.
Do not plug more than two units into a given receptacle (example: displays in 2x2 video wall 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
This display is rated for the following operational conditions:
Temperature: 32°F -104°FHumidity : 20-80%
4. General Information
1.1 PC Settings:
The PC needs to be set to an appropriate graphics mode that has the same resolution as the panel to have clear screen image. And
the vertical refresh rate should be set to one of 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
mitigate screen flicker. If you want to view 4k2k@60Hz resolution, must use a PC that supports 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 dedicated cable. (4K2K@60Hz)
Set Up for Operation

www.gpodisplay.com DN46HE
Note.
If you turn the monitor on when the set is cold, the screen may flicker. This is normal.
Sometimes red, green, or blue spots may appear on the screen. This is normal.
Use a High Speed HDMI®/TM cable.
Use a certified cable with the HDMI logo attached. If you do not use a certified HDMI cable, the screen may
not display or a connection error may occur
Recommended HDMI Cable Types
-High-Speed HDMI®/TM Cable
-High-Speed HDMI®/TM Cable with Ethernet
Connect the signal input cable and tighten it by turning any associated locking clockwise.
Avoid displaying static images on the screen for a long period of time to prevent image retention/burn-in. Use a
screensaver if possible.
If you cannot hear any sound in HDMI mode, check your PC settings. Some PCs require you to manually change
the default audio output to HDMI.
Apple computers may require an adapter to connect to this monitor. Call or visit their web site for more
information.
Set Up for Operation
Connect the signal input cable and tighten it by turning any associated locking screws clockwise.
Do not press the screen with your finger for a prolonged period as this may result in temporary distortion on
the screen
A wireless communication device near your monitor can affect the image.

Do not Cover Ventilation Areas.
Carefully install DN46HE so as to avoid covering/obstructing the fan air holes.
If the holes are covered and airflow is obstructed, internal temperature will rise rapidly, potentially causing malfunction. Do
not cover ventilation areas.
Set Up for Operation
Ventilation
Note: This display is intended for use in ceiling-mounted applications with the LCD panel facing downward. Ventilation is
specifically designed for this type of mounting. Consult with GPO Display in cases where the display will not be placed in a
downward-facing mount position in a ceiling. Refer to Premier PBM-UNI mount (or equivalent) instructions.

Media Player Installation Quick Guide
Place foam padding or blanket on a table.
Make sure the surface is clean and free of
any small fragments or particles. This will
ensure that the LCD panel is not scratched
or damaged when the display is placed
face-down.
Be sure to wear anti static gloves
before assembly.
Carefully and gradually place the display
face-down on the blanket or foam. Use the
handles when doing
*Avoid placing pressure on the front edge
of the bezels.
To install media player, remove the cable housing.
Remove the screws around the perimeter of the
cable housing cover. There are twelve (12) screws
in total. These can be found in the area shown in
the red dotted lines to the left.

Connect RS232 Cables
1. While mounting display, insert any cables used for Power, video inputs or outputs into the set.
2. Prior to insertion of the next set into neighboring Wall Unit, insert cables (including RS-232) from the outputs of the first set into
the inputs of the second set.
3. Repeat steps 1-2 for next set, if necessary.
4. The RS-232 daisy chain limitation is listed as 30 displays, although theoretically more units can be accommodated.
5. Daisy-chaining can be initiated from any unit. There is no terminator at the end of the unit. It is always recommended to
record/make note of the chaining diagram as it is crucial to determining issues with communication.
