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:
• How to install the monitor on a new computer on page 22.
• How to upgrade the monitor on an existing computer on page 23.
• 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 Getting the most from your BenQ monitor on page 21. 
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

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 Vista 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 7 system on page 24.
• How to install on Windows Vista systems on page 25.
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.

How to watch 3D content on your monitor
Your monitor supports playing three-dimensional (3D) content transferred through DVI-D Dual 
Link cable. Yet you need to have the appropriate hardware equipment and software programs 
that are compatible with 3D playback.
System requirements
• BenQ LCD Monitor XL2420T / XL2420TX
• Compatible 3D glasses
• PC with Microsoft Windows Vista or Windows 7 Operating System
• Compatible graphics processing units (GPU) with the latest driver files installed
• Compatible software programs that play 3D playback
For the compatible accessories, visit 
http://www.nvidia.com/object/3d-vision-requirements.html. For the appropriate 3D players, 
check with the 3D content providers.
Playing 3D content
Follow the instruction manuals of your 3D accessories to install the hardware and the software. 
If the 3D glasses are properly connected and IR signal is detected, the IR emitter indicator on 
the bottom right of the monitor and on the IR emitter module (purchased separately for 
XL2420T) will light up.
To improve the performance of 3D glasses, you can do the following:
• On XL2420TX, check if there are any obstacles in front of the IR sensor located at the front 
top of the monitor that keep the sensor from receiving signals from the 3D glasses.
Go to 
System and Emitter Mode and change the setting as needed. See Emitter Mode 
(XL2420TX only) on page 50 for more information.
• On XL2420T or XL2420TX, follow the instruction manuals of the 3D accessories to make 
adjustment.
If you want to adjust the brightness when watching 3D content, go to 
Picture and NVIDIA® 3D 
LightBoost
™. See Brightness (during 2D playback) / NVIDIA® 3D LightBoost™ (during 3D 
playback) on page 40 for more information.
3D content can be transferred to XL2420TX through HDMI cable (version 1.3 or above) as well.
Not all menu options are available for 3D playback.
• Contact NVIDIA or visit NVIDIA website (http://www.nvidia.com/page/home.html) for the purchase and the 
settings of the compatible GPU.
• Visit the NVIDIA website (www.nvidia.com/3DUpdate) for the latest GPU driver files.
IR sensor is embedded in the front bezel of your XL2420TX and is not visible to you.

Safety information for watching 3D content
• You may experience eye strain after watching 3D content for certain period of time. Take off 
the 3D glasses and take a rest to relieve the eye strain.
• If you experience headaches, dizziness, or nausea, stop watching 3D content immediately. You 
might need to consult a doctor if the symptoms last.
• Watching 3D content for a long period of time may increase health risks. For small children, 
the elderly, the pregnant women or people who have high blood pressure or other health 
concerns, consult a doctor before watching 3D content.
