How to assemble your monitor hardware
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 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.

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.

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 or HDMI) 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

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.

Troubleshooting
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
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.
No sound can be heard from the built-in speakers (for models with speakers only):
• Check whether Line In is properly connected.
• Increase the volume (volume may be muted or too low).
• Remove your headphone and/or external speakers. (If they are connected to the monitor,
the built-in speakers are automatically muted.)
No sound can be heard from the connected external speakers (for models with speakers
only):
• Remove your headphone (if the headphone is connected to the monitor).
• Check whether the headphone jack is properly connected.
• If the external speakers are USB-powered, check whether the USB connection is OK.
• Increase the volume (volume may be muted or too low) on the external speakers.
