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.

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 
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:
• 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.

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.

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). 
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. 
See:
• How to install on Windows 8 system on page 17.
• How to install on Windows 7 system on page 18.
• How to install on Windows Vista systems on page 19.
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.

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.
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   keys to select 
DISPLAY and press the ENTER key to enter the menu.
5.  If you notice a vertical noise (like a curtain effect-shimmering of vertical lines), press the 
 or   keys to select 
Pixel Clock and press the ENTER key. Then press the   or   
keys to adjust the monitor until the noise disappears.
6.  If you notice a horizontal noise, press the   or   keys to select 
Phase and press the 
ENTER key. Then press the   or   keys to adjust the monitor until the noise 
disappears.
When you connect a digital input signal 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.
