							  21   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 stand.
Lay the screen face down on a clean and well-padded 
surface. Detach the monitor stand as instructed in step 
1~2 in How to detach the stand and the base on page 
16.
2. Remove the screws on the back cover.
Use a cross-pointed screwdriver to release the screws 
on the back cover. The use of a magnetic-head 
screwdriver is recommended to avoid of losing the 
screws.
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.
3. 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 23.
• How to upgrade the monitor on an existing computer on page 24.
• 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.
1.  Follow the instructions in How to assemble your monitor hardware on page 10. 
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

6.  Click 
Finish.
7.  Restart the computer.
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.
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 8.1, Windows 8, and Windows 7 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 (8.1) system on page 25.
• How to install on Windows 7 system on page 26.
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.

							30  How to adjust your monitor  
Picture optimization
The easiest way to obtain an optimal display from an analog (D-Sub) input is to use the Auto 
Adjustment
 function. Go to Display and Auto Adjustment 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 any of the control keys to bring up the hot key menu. Select 
 (Menu) to access 
the main menu.
3.  Go to 
Display and Auto Adjustment.
4.  If you notice a vertical noise (like a curtain effect-shimmering of vertical lines), select 
Pixel 
Clock
 and adjust the monitor until the noise disappears.
5.  If you notice a horizontal noise, select 
Phase and adjust the monitor until the noise 
disappears.
Customizing the hot keys
The left 3 control keys (also called custom keys) perform as hot keys to provide direct access 
to pre-defined functions. You can change the default setting and designate different functions for 
these keys.
1.  Press any of the control keys to bring up the hot key menu, and press 
 (Menu) to 
access the main menu.
2.  Go to 
System.
3.  Select the custom key you want to change.
4.  In the sub menu, select a function that can be accessed by this key. A pop-up message will 
appear, showing that the setup is complete.
Adjusting display mode
To display images of aspect ratio other than 16:9 and size other than the panel size of your 
purchased model, you can adjust the display mode on the monitor.
1.  Press any of the control keys to bring up the hot key menu, and press 
 (Menu) to 
access the main menu.
2.  Go to 
Picture Advanced and Display Mode.
3.  Select an appropriate display mode. The setting will take effect immediately.
When you connect a digital input signal using a digital (DVI, HDMI, or DP) cable to your monitor, 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 Adjustment function.
