How to assemble your monitor hardware
• If the computer is turned on you must turn it off before continuing.
Do not plug-in or turn-on the power to the monitor until instructed to do so.
• The following illustrations are for your reference only. Available input and output jacks may vary depending on
the purchased model.
1. Attach the monitor base.
Please be careful to prevent damage to the monitor. Placing
the screen surface on an object like a stapler or a mouse will
crack the glass or damage the LCD substrate voiding your
warranty. Sliding or scraping the monitor around on your
desk will scratch or damage the monitor surround and
controls.
Protect the monitor and screen by clearing a flat open
area on your desk and placing a soft item like the
monitor packaging bag on the desk for padding.
Gently lay the screen face down on a flat clean padded
surface.
While holding the monitor firmly against the desk, pull
the monitor stand arm upwards clear of the monitor.
Orient and align the stand base socket with the end of
the stand arm, then push them together until they click
and lock into place.
Gently attempt to pull them back apart to check that
they have properly engaged.

minimize unwanted reflections from other light sources.
2. Connect the video cable
Do not use both DVI-D cable and D-Sub cable on the same
PC. The only case in which both cables can be used is if they
are connected to two different PCs with appropriate video
systems. (Not available for analog-only models).
To Connect the D-Sub Cable
Connect the plug of the D-Sub cable (at the end
without the ferrite filter) to the monitor video socket.
Connect the other end of the cable (at the end with the
ferrite filter) to the computer video socket.
Tighten all finger screws to prevent the plugs from
accidently falling out during use.
To Connect the DVI-D Cable
Connect the plug of the DVI-D cable (at the end without
the ferrite filter) to the monitor video socket. Connect
the other end of the cable (at the end with the ferrite
filter) to the computer video socket.
Tighten all finger screws to prevent the plugs from
accidently falling out during use.
If there is more than one video transmission method available
to you, you might want to take the picture quality of each
video cable into consideration before making the connection.
- Better quality: DVI-D
- Good quality: D-Sub
The video cables included in your package and the socket
illustrations on the right may vary depending on the product
supplied for your region.
10 How to assemble your monitor hardware

How to detach the base
1. Prepare the monitor and area.
Turn off the monitor and the power before unplugging
the power cable. Turn off the computer before
unplugging the monitor signal cable.
Protect the monitor and screen by clearing a flat open
area on your desk and placing a soft item like a towel on
the desk for padding, before laying the screen face down
on a flat clean padded surface.
Please be careful to prevent damage to the monitor. Placing
the screen surface on an object like a stapler or a mouse will
crack the glass or damage the LCD substrate voiding your
warranty. Sliding or scraping the monitor around on your
desk will scratch or damage the monitor surround and
controls.
2. Press the locking clips to detach the
monitor base from the monitor stand arm.
12 How to assemble your monitor hardware
Using the monitor wall mounting kit
The back of your LCD monitor has a VESA standard mount with 100mm pattern, allowing the
installation of a wall mount bracket. Before starting to install a monitor wall mounting kit,
please read the precautions carefully.
Precautions:
• Install your monitor and monitor mounting kit on a wall with flat surface.
• Ensure that the wall material is stable to support the weight of the monitor.
• Turn off the monitor and the power before disconnecting the cables from the LCD monitor.
1. Remove the monitor base.
Lay the screen face down on a clean and well-padded
surface.
Detach the monitor base as instructed in How to
detach the base on page 12.
In case you intend to use your monitor on the stand in the
future, please keep the monitor base, monitor stand, and
screws somewhere safe for future use.
2. Follow the instruction manuals of the wall
mount bracket you purchased to complete
the installation.

Getting the most from your BenQ monitor
To gain the most benefit from your new BenQ LCD monitor, you should install the custom
BenQ LCD Monitor driver software as provided on the BenQ LCD Monitor CD-ROM.
The circumstances under which you connect and install your BenQ LCD Monitor will
determine which process you need to follow to successfully install the BenQ LCD Monitor
driver software. These circumstances relate to which version of Microsoft Windows you are
using, and whether you are connecting the monitor and installing the software onto a new
computer (without existing monitor driver software), or whether you are upgrading an existing
installation (which already has existing monitor driver software) with a newer monitor.
In either case however, the very next time you turn on your computer (after connecting the
monitor to your computer), Windows will automatically recognize the new (or different)
hardware, and will launch its
Follow the wizard instructions until it asks you to select a monitor model. At that point, click
the
Have Disk button, insert the BenQ LCD Monitor CD-ROM and select the appropriate
monitor model. Further details and step-by-step instructions for either an automatic (new) or
upgrade (existing) installation, see:
Found New Hardware wizard.
• How to install the monitor on a new computer on page 15.
• How to upgrade the monitor on an existing computer on page 16.
• If you require a User Name and Password to login to your Windows computer, you must be logged on as an
Administrator or as a member of the Administrators group in order to install the monitor driver software.
Furthermore, if your computer is connected to a network which has security access requirements, network
policy settings may prevent you from installing software on your computer.
• To check the name of the purchased model, refer to the specification label on the back of the monitor.

How to install the monitor on a new computer
This instruction details the procedure for selecting and installing the BenQ LCD Monitor driver
software on a new computer which has never had a monitor driver installed before. This
instruction is only suitable for a computer which has never been used before, and for which the
BenQ LCD Monitor is the first ever monitor to be connected to it.
If you are adding the BenQ LCD Monitor to an existing computer that has already had another monitor
connected to it (and has monitor driver software installed), you should not be following these instructions. You
should instead be following the instructions for How to upgrade the monitor on an existing computer.
1. Follow the instructions in How to assemble your monitor hardware on page 9.
When Windows starts, it will automatically detect the new monitor and launch the Found New
Hardware Wizard. Follow the prompts until it displays the option to Install Hardware Device
Drivers.
2. Insert the BenQ LCD Monitor CD-ROM into a CD drive on the computer.
3. Check Search for a suitable driver for my device option, and click Next.
4. Check the option for CD-ROM drives (uncheck all others) and click
Next.

How to upgrade the monitor on an existing computer
This instruction details the procedure for manually updating the existing monitor driver
software on your Microsoft Windows computer. It is currently tested as compatible for
Windows 8, Windows 7, and Windows Vista Operating System (OS).
The BenQ LCD Monitor driver for your model may well function perfectly with other versions of Windows,
however, as at the time of writing, BenQ has done no testing of this driver on other versions of Windows and
cannot guarantee its operation on those systems.
Installing monitor driver software involves selecting an appropriate information file (.inf) on the
BenQ LCD Monitor CD-ROM for the particular model monitor you have connected, and
letting Windows install the corresponding driver files from the CD. You need only steer it in the
right direction. Windows has an Upgrade Device Driver Wizard to automate the task and guide
you through the file selection and installation process.

Troubleshooting
Frequently asked questions (FAQ)
The image is blurred:
Read the instructions on the link "Adjusting the Screen Resolution" on the CD, and then select
the correct resolution, refresh rate and make adjustments based on these instructions.
How do you use a VGA extension cable?
Remove the extension cable for the test. Is the image now in focus? If not, optimize the image
by working through the instructions in the "Adjusting the refresh rate" section on the link
"Adjusting the Screen Resolution". It is normal for blurring to occur due to conduction losses
in extension cables. You can minimize these losses by using an extension cable with better
conduction quality or with a built-in booster.
Does the blurring only occur at resolutions lower than the native (maximum) resolution?
Read the instructions on the link "Adjusting the Screen Resolution" on the CD. Select the
native resolution.
Pixel errors can be seen:
One of several pixels is permanently black, one or more pixels are permanently white, one or
more pixels are permanently red, green, blue or another color.
• Clean the LCD screen.
• Cycle power on-off.
These are pixels that are permanently on or off and is a natural defect that occurs in LCD
technology.
The image has a faulty coloration:
It has a yellow, blue or pink appearance.
Select
message box to reset the color settings to the factory defaults.
If the image is still not correct and the OSD also has faulty coloration, this means one of the
three primary colors is missing in the signal input. Now check the signal cable connectors. If
any pin is bent or broken off, please contact your dealer to get necessary support.
No image can be seen:
Is the prompt on the display illuminated in green?
MENU > PICTURE > Color > Reset Color, and then choose “YES” in the “Caution”
If the LED is illuminated in green and there is a message “Out of Range” on the screen, this
means you are using a display mode that this monitor does not support, please change the
setting to one of the supported mode. Please read the “Preset display modes” section from
the link "Adjusting the Screen Resolution".
35 Troubleshooting
Faint shadow from the static image displayed is visible on the screen:
• Activate the power management function to let your computer and monitor go into a low
power "sleep" mode when not actively in use.
• Use a screensaver to prevent the occurrence of image retention.
Is the prompt on the display illuminated in orange?
If the LED is illuminated in orange, the power management mode is active. Press any button on
the computer keyboard or move the mouse. If that does not help, check the signal cable
connectors. If any pin is bent or broken off, please contact your dealer to get necessary
support.
Is the prompt on the display not illuminated at all?
Check the power supply mains socket, the external power supply and the mains switch.
The image is distorted, flashes or flickers:
Read the instructions on the link "Adjusting the Screen Resolution" on the CD, and then select
the correct resolution, refresh rate and make adjustments based on these instructions.
You are running the monitor at its native resolution, but the image is still distorted.
Images from different input sources may appear distorted or stretched on the monitor running
at its native resolution. To have the optimal display performance of each type of input sources,
you can use the "Display Mode" function to set a proper aspect ratio for the input sources.
See Display Mode on page 30 for details.
The image is displaced in one direction:
Read the instructions on the link "Adjusting the Screen Resolution" on the CD, and then select
the correct resolution, refresh rate and make adjustments based on these instructions.
The OSD controls are inaccessible:
• To unlock the OSD controls when the OSD is preset to be locked, press and hold the
“MENU” key for 15 seconds to enter the “OSD Lock” option and make changes.
• Alternatively, you may use the or keys to select “NO” in the “OSD Lock” submenu
from the “OSD Settings” menu (under SYSTEM), and all OSD controls will be accessible.
