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 26. · How to upgrade the monitor on an existing computer on page 27. · 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.

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 or the key on the OSD Controller 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.

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. 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. 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". 56 Troubleshooting 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 45 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. Troubleshooting 57 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: · If you have removed the sensor protection sticker. · If the Eye Protect function is set to ON. Check Ergonomics > Eye Protect. · 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. · If you have removed the sensor protection sticker. · 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. Need more help?
