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 29.
• How to upgrade the monitor on an existing computer on page 30.
• 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 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.

How to adjust your monitor
Picture optimization (for models with D-Sub inputs)
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.
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.
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

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

Troubleshooting
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.
• (For models with D-Sub inputs) If a VGA extension cable is used, 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.

The image has a faulty coloration.
It has a yellow, blue or pink appearance.
Go to Picture and Reset Color, and then choose YES 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.

Troubleshooting
The LED indicator is white or orange.
• If the LED lights up in solid white, the monitor is powered on.
• If the LED is illuminated in white 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".
• 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.
• If the LED is off, check the power supply mains socket, the external power supply and the
mains switch.
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.
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 sources. See
Display Mode on page 46 for details.
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 it is preset to be locked, press and hold any key for 10
seconds.
No sound can be heard from the connected external speakers.
• 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.

No sound can be heard from the built-in speakers:
• 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.)
The light sensor of the monitor does not work well.
The light sensor is located at the front bottom of the monitor. Please check:
• (For BL2420) If the Eye Protect function is set to ON. Check Ergonomics > Eye Protect.
(For BL2423) If the Bright Intelligence function is set to ON. Check Ergonomics > Bright
Intelligence.
• If there are any obstacles in front of the sensor that keep the sensor from detecting the light
properly.
• If there are any objects or clothing in bright colors in front of the sensor. Bright colors
(especially white and fluorescent colors) reflect light and the sensor cannot detect the main
light sources.
The ECO sensor of the monitor does not work well.
• The ECO sensor is located at the front bottom of the
monitor. Check if there are any obstacles in front of the
sensor that keep the sensor from detecting your presence
properly.
• The colors and the materials of your clothes may affect the
detection. Adjust the sensor range if needed. See Sensor
Range on page 55 for more information.
• Adjust the distance between you and the monitor.
If none of the proceeding actions works, it is probably because the materials of your clothes
are unique and cannot be detected by the ECO sensor. Please be noted that this is neither a
manufacturing defect nor is the sensor damaged. You should turn off the ECO sensor for now
in Eco > ECO Sensor.
