3. 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.
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.
Carefully lift the monitor, turn it over and place it
upright on its stand on a flat even surface.
You should position the monitor and angle the screen
to minimize unwanted reflections from other light
sources.

Either
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.

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.
The DVI-D format is used for direct digital connection
between source video and digital LCD monitors or
projectors. The digital video signals produce a superior
quality picture than analog video signals.
The video cable included in your package and the
socket illustrations on the right may vary depending on
the LCD model.
3. Connect the power cable to the monitor.
Plug one end of the power cord into the socket labelled

4. Getting the most from your BenQ monitor
To gain the most benefit from your new BenQ color LCD flat screen 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 Found New Hardware wizard.
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:
• 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.
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.
5. Look to confirm that the wizard has selected the correct name of your monitor and click
Next.
6. Click Finish.
7. Restart the computer.
To find the suitable driver files for the purchased model, refer to the following table.

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 XP,
Windows Vista, and Windows 7 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.

5. Picture optimization
The easiest way to obtain an optimal display from an analog (D-Sub) input is to use the AUTO key
function. Press the AUTO key to optimize the currently displayed image to the screen.
When you connect a digital video output using a digital (DVI) cable to your monitor, the AUTO
key and the Auto Adjustment function will be disabled, because the monitor will automatically
display the best image.
Please ensure that the connected graphic card on your computer is set to the native resolution of the
monitor when you use the AUTO key function.
If you wish, you can always adjust the screen geometric settings manually using geometry menu
items. To assist you in this endeavour, BenQ has provided a screen test image utility which you can
use to check for screen color, grayscale and line gradient display.
1. Run the test program auto.exe from CD-ROM. You could also use any other image, such as
the desktop of your operating system. However, we recommend that you use auto.exe. As you
run auto.exe, a test pattern displays.
2. Press the AUTO key on the monitor.
3. Press the MENU key to access the monitor On-Screen Display (OSD) menu.
4. Use the
or

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 MENU > PICTURE > Color > Reset Color, and then choose “YES” in the “Caution”
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?
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".
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 27 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.
