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) from the downloaded driver files for the particular model monitor you have connected, and letting Windows install the corresponding driver files. 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.

Frequently asked questions (FAQ)

Imaging

The image is blurred.

• Download Resolution file from the website (see Product support on page 3). Refer to "Adjusting the Screen Resolution". And then select the correct resolution, refresh rate

and make adjustments based on these instructions.

• If a VGA extension cable is used, remove the extension cable for the test. Is the image now in focus? Download Resolution file from the website (see Product support on page 3). Refer

to "Adjusting the Screen Resolution". And then select the correct resolution, refresh rate and make adjustments based on these instructions to optimize the image. 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?

Download Resolution file from the website (see Product support on page 3). Refer to "Adjusting the Screen Resolution". Select the native resolution.

Pixel errors can be seen.

One of several pixels is permanently black, one or more pixels are permanently white, one or more pixels are permanently red, green, blue or another color.

• 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. Download Resolution file from the website (see

Product support on page 3). Refer to "Adjusting the Screen Resolution". And then select

the correct resolution, refresh rate and make adjustments based on these instructions.

• 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.
