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, Windows 7, and Windows Vista 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.

Troubleshooting

Frequently asked questions (FAQ)

The image has a faulty coloration.

• The default Picture Mode is FPS1, which is designed for FPS games. If you prefer other picture modes, go to Picture Advanced and change setting in Picture Mode.

• If the image 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.

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.

How do you use a VGA extension cable?

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.

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.

• Clean the LCD screen.

• Cycle power on-off.

• These are pixels that are permanently on or off and is a natural defect that occurs in LCD technology.

56 Troubleshooting

No image can be seen.

Is the prompt on the display illuminated in green?

If the LED is illuminated in green 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".

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.

Is the prompt on the display illuminated in orange?

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.

Is the prompt on the display not illuminated at all?

Check the power supply mains socket, the external power supply and the mains switch.

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 47 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 second.

57 Troubleshooting

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.
