Your LCD display provides USB 2.0 ports for connecting to various devices including
computers, flash drives and wireless LAN adapters. This section provides basic information
about the USB 2.0 interface and serves as a reference for the deployment of your USB
connections.
USB terminology
Te r mDescription/explanation
Host,
Function
A USB network consists of one master and multiple slave devices in a star
topology as illustrated below:
The master device (referred to as the “Host”) is on top of all other slave devices
(called “Function”). A computer is the most common USB host. Any device that
has a USB host controller and related hardware and software installed can also
become a USB host. A USB function can be a USB mouse, keyboard or storage
device.
18 Display installation guide
A maximum of 7 tiers (including the root tier) are allowed in a single USB
network. Note that a USB device that performs both as a hub and a function
occupies two tiers.
Te r mDescription/explanation
UpstreamThe direction of data transmission from a USB function to a host or hub.
DownstreamThe direction of data transmission from a USB host or hub to a function.
HubA USB device that provides upstream connection (port) to a host and
downstream connections (ports) to multiple functions.
Root hubA USB host that also performs the functions of a hub.
Speed (low-speed,
Three different speeds are currently defined in the USB 2.0 specification:
full-speed and highspeed)
• Low-speed: data transmission at 1.5Mbps
• Full-speed: data transmission at 12Mbps
• High-speed: data transmission at 480Mbps
The actual transmission speed is determined by the device with the
lower (or lowest) speed. For example, if a low-speed (1.5Mbps) USB
peripheral is connected to a high-speed (480Mbps) USB host, the
maximum transmission speed between these devices will be 1.5Mbps,
not 480Mbps.
Active (self-
powered) device
Passive (bus-
powered) device
A USB device that has it own power supply and can operate without the
power supplied by the USB host.
A USB device that does not have its own power supply and solely relies
on the power supplied by the USB host.
USB connectors and receptacles
USB connectors and receptacles are grouped into two types: Type-A and Type-B.

USB cable length
For each passive connection between a two USB devices, the maximum length for USB 3.0 is 3
meters, and the maximum length for USB 2.0 is 5 meters. To extend USB connection beyond
this length limit, an active extension cable has to be used to ensure stable signal transmission
and reliable power supply.
• Type-A receptacles are used as outputs from host systems
and hubs.
• Type-A plugs are always oriented towards the host system
and mate with Type-A receptacles.
• Type-B receptacles are used as inputs to hubs or devices.
• Type-B plugs are always oriented towards a USB hub or
device and mate with Type-B receptacles.
19 Display installation guide
Prohibited cable assemblies
Some cable assemblies are prohibited in the USB specifications and are not recommended as
they may not work in all instances. For example, passive extension cable assembly: a cable that
has a Type-A plug on one end and a Type-A receptacle on the other, or a Type-B plug on one
end and a Type-B receptacle on the other. This allows multiple cable segments to be connected
together, possibly exceeding the maximum permissible cable length.

Setting the display position
Video sources
After all the displays are installed properly to a video wall, you need set the position of each
display to determine how to display the input image.
Without setting the display position, each display outputs the complete picture independently.
Once the position is set, the video source (e.g. computer) identifies the number of connected
displays and transfer part of the picture to each display accordingly. The video wall then outputs
one picture as a whole.
If you prefer to show different pictures on the displays of the video wall, you will need to have
independent video source for each display.
Though the video sources vary, you can still manage all displays via remote control, RS-232 commands, or LAN
control in this case.

Once you have installed the video wall, you need to set an ID number for each display to
identify one among the multiple displays easily. This is helpful for video wall management, such
as power management, OSD control, or color management. It is also helpful if additional
adjustment is required for a specific display.
To set the ID number, go to Setting > Set Monitor ID on each display for configuration. Pay
attention not to set the same ID number for different displays, as the commands for video wall
management would not be received correctly.
Set the ID number starting from 1 to 98, depending on the number of displays daisy chained.
There is no specific direction while going through all displays setting up the ID numbers.
Following are some examples for your reference.
To set the ID number of each display for PL490/PL552/PL553/PH5501/PH5502, adjust the ID number for
controlling the display via the RS232C connection. Each display must have a unique ID number when multiple sets
of this display are connected. Monitor ID number range is between 1 to 225. The default setting is 1.
All models of MDA only support from 1-98.

• Make sure that the signal is output from the same source (e.g. D-Sub).
• It is recommended to use cables of equal length for connection.
• Do not use more than 2 splitters to produce video wall.
• If the total fitment width of the video wall is more than 10 meters, use an amplifier or
resistance wire avoid signal attenuation during transmission.
• If the signal came from more than one computer, make sure that all computers use the same
type of graphic card.
If it is the display that went wrong, check the following:
• Check if all the settings of the following options in the Picture menu on all displays are
identical.
- Picture Mode (Standard mode is recommended)
- Backlight
- Contrast
- Brightness
- Chroma

77 Troubleshooting
Preventing afterimage burn-in
If you leave the screen fixed on a stationary image for an extended period of time, afterimage
burn-in or defective pixels may occur. Power-saving mode or a dynamic screen saver should be
activated in case you will not be using the product for an extended period of time.
When the LCD panel is not operating normally, afterimage burn-in may occur.
Normal operation means a consecutively changing video pattern. If the LCD panel shows a
fixed pattern for an extended period of time, a little voltage difference may occur between the
electrodes in pixels controlling the liquid crystals.
The voltage difference between electrodes may increase with time. This can cause the liquid
crystals to get thinner. A previous image can stay on the screen as the pattern changes. To avoid
this situation, the compiled voltage difference should be diminished.
To avoid afterimage burn-in, turn off the power or set the PC or system to run a screen saver
when not in use. Warranty service may be restricted relying on the instruction guide.
Power saving mode
• After using the product for 12 hours, turn it off for 2 hours.
• Power saving mode may vary by models. Please refer to user manuals for more information.
• Use a recommended screen saver. A single-color or moving-image screen saver is the best.
Regular color change
• Switch between 2 colors every 30 minutes.
• Avoid mixing a text color and background color of contrasting brightness.
• Prevent using grey as it may cause afterimage burn-in.
• Prevent using colors of contrasting brightness, e.g., black and white.
Regular text color change
Use bright colors of similar brightness and regularly show a moving image along with a logo.
• Change text color and background color every 30 minutes.
• Show a moving image along with a logo for 60 seconds after using for 4 hours.

Warranty information
I, _____________________ hereby confirm that I have read this document and
checked the items mentioned above.
BenQ warranty does not cover the damages caused by improper installation, operation, or
storage of the product, including but not limited to the following:
1. Damages to the packaging or product after re-packing. This includes but not limited to the
color change of shock indicator (if available), serious scratches on the package, and/or broken cushions or PE bags. Please make sure to check the product and all the supplied items
once the original package is unsealed.

storage, or inappropriate way to move the display.
3. Scratches, cracks, faded paint, and/or other physical damages to the panel, bezel, metal
frame, rear cover, and accessories.
4. Abnormal display (lines, mura, or light leakage) caused by the collision or excessive force
during installation.
5. Missing accessories during installation.
6. Any damages or performance failure caused by not following the instructions in the
Installation Handbook.
7. LCD screens, like plasma (PDP) and conventional CRT (Cathode Ray Tube) screens, are
also susceptible to 'screen burn-in' or 'image retention' which can be found on the screen
as visible fixed lines and shades. To avoid such damage to the screen, avoid displaying still
images (like On-Screen Display menus, TV station logos, fixed/inactive text or icons) for
more than two hours. Change the aspect ratio from time to time. Fill the entire screen
with the image and eliminate the black bars whenever possible. Avoid displaying images in
4:3 aspect ratio over a long period of time, otherwise there may be visible burn marks on
the screen as two vertical lines.
• It is the sole responsibility of the user if problems (e.g. system failure) occurred due to non-factory installed
parts and/or non-original accessories.
• Under certain circumstances, condensation may occur on the inner side of the cover glass, it's a natural
phenomenon and will not affect the operation of the display. This condensation will usually disappear after
around 30 minutes of normal operation.
