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 34.
• How to upgrade the monitor on an existing computer on page 35.
• 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.
1. Follow the instructions in How to assemble your monitor hardware on page 19.
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 10, Windows 8 (8.1), 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.

the main menu.
2. Go to Picture > Advanced > Display Mode.
3. Select an appropriate display mode. The setting will take effect immediately.
Choosing an appropriate color mode
Your monitor provides various color modes that are suitable for different types of images. See
Color Mode on page 59 for all the available color modes.
Go to Color > Color Mode for a desired color mode.
The computer’s color profile (ICC profile) may not best suit your monitor. If you want to make sure to obtain the
accurate color matching representation, change the computer’s ICC profile to ensure the computer works better
with the monitor. Visit www.BenQ.com > the purchased model > the Downloads or Support tab > the User
Manual tab to access the ICC Profile Installation Guide for instructions. Alternatively, enable the ICC Sync
function from Display Pilot (page 45). Refer to the Display Pilot manual for details.
Working with two video sources (KVM Switch)
If you have two computer systems, you might find yourself busy going back and forth between
two sets of keyboard and mouse to control each display separately. Now with the KVM feature
and sufficient I/O ports on one monitor, you can work with one set of keyboard and mouse
only.
To use KVM Switch feature, toggle between Thunderbolt 3 (PD2720U / PDS3220U) /
USB-C (PD3420Q) or USB Upstream under KVM Switch.
• KVM Switch > Thunderbolt 3 (PD2720U / PDS3220U) / USB-C (PD3420Q): Switches to
the Thunderbolt™ 3 (PD2720U / PDS3220U) / USB-C™ (PD3420Q) input.
• KVM Switch > USB Upstream: Switches to one of the video inputs other than
Thunderbolt™ 3 (PD2720U / PDS3220U) / USB-C™ (PD3420Q). With appropriate setting,
the display is switched to the set input while the keyboard and mouse control is switched as
well. To determine the input, see Setting up the second video source for KVM Switch before
use on page 46.
You can designate one of the custom keys to KVM Switch to toggle between the options
quickly. See Customizing the hot keys on page 42.
Setting up the second video source for KVM Switch before use
One of the video sources is pre-defined to be transmitted via Thunderbolt™ 3 (PD2720U /
PDS3220U) / USB-C™ (PD3420Q) and cannot be changed. The other source can come from
other available inputs and should be set appropriately in advance.
1. Connect the second video source to one of the video inputs other than Thunderbolt™ 3
(PD2720U / PDS3220U) / USB-C™ (PD3420Q) on the monitor using an appropriate cable.

(Menu) to access
• For Scenario A: Working with two computers and one monitor on page 47, select the video input
just connected. When USB Upstream under KVM Switch is selected, the display and USB
control change from Thunderbolt™ 3 (PD2720U / PD3220U) / USB-C™ (PD3420Q) to the
other connected video input.
• For Scenario B: Working with two computers and two monitors on page 48 and Scenario C:
Working in PBP mode on page 48, select None. This is because two video inputs are displayed
simultaneously and require no switch. The None option will switch USB control only.
If None is selected from KVM Switch > Video Input for Scenario A: Working with two computers and one
monitor and USB Upstream is selected for KVM Switch, the screen does not display anything from the second
source as there is none. You cannot control the current display (from Thunderbolt™ 3 or USB-C™, depending
on your purchased model) either as the keyboard and mouse control has been switched away. In this case, select
a video input manually from Input > Signal Input.
• After the second source has been set properly from KVM Switch > Video Input, you can go to KVM
Switch > Auto Switch and turn on the Auto Switch function. Once enabled, if USB or Thunderbolt™ 3
(PD2720U / PD3220U) / USB-C™ (PD3420Q) cable is disconnected, the USB input source and the control
will be switched to the other computer automatically.
• The KVM Auto Switch might not switch video and USB signals simultaneously if None is selected from KVM
Switch > Video Input. In this case, select a video input manually from Input > Signal Input.
