141 Getting the most from your BenQ monitor

How do I gain the most benefit from my new monitor?

To gain the most benefit from your new BenQ color LCD flat screen 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 recognise 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-ROMand select the appropriate monitor model. Further details andstep-by-stepinstructions for both an automatic (new) or upgrade (existing) installation follow. See:

How to install the monitor on a new computer.

How to upgrade the monitor on an existing computer

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.

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 install your monitor hardware.

When Windows (2000 or later) 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.

2.Insert the BenQ LCD Monitor CD-ROMinto a CD drive on the computer.

3.Check Search for a suitable driver for my device option, and click Next.

4.Check the option for CD-ROMdrives (uncheck all others) and click Next.

5.Look to confirm that the wizard has selected the correct name of your monitor as "BenQ FP91GP/FP91GX" and click Next.

6.Click Finish.

7.Restart the computer.

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 currrently tested as compatible (and recommended only) for Windows 98, Windows ME, Windows 2000, and Windows XP 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-ROMfor 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.

See:

How to install on Windows XP systems.

How to install on Windows 2000, ME, & 98 systems.

151 How to adjust the screen resolution

Due to the nature of liquid crystal display (LCD) technology, the picture resolution is always fixed. The best possible picture for your FP91GP/FP91GX is achieved with a resolution of 1280x1024. This is called “Native Resolution” or maximal resolution – that is, the clearest picture. Lower resolutions are displayed on a full screen through an interpolation circuit. However flaws do occur with the interpolated resolution.

To take full advantage of LCD technology you should select the native resolution setting of 1280x1024.

1. Open Display Properties and select the Settings tab.

You can open Display Properties by right-clickingon the Windows desktop and selecting Properties from thepop-upmenu.

2. Use the slider in the ‘Screen area’ section to adjust the screen resolution.

Select the recommended resolution of 1280x1024 then click Apply.

If you select some other resolution, be aware that this other resolution is interpolated and may not accurately display the screen image as well as it could do at the native resolution setting.

3.Click OK then Yes.

4.Close the Display Properties window.

How to adjust the screen resolution 18

161 How to adjust the screen refresh rate

You don’t have to choose the highest possible refresh rate on an LCD display, because it is not technically possible for an LCD display to flicker. The best results are obtained by using the factory modes already set in your computer. There is a table with the factory modes in the specification section of this User’s Manual.

You can choose 60, 70 and 75 Hertz, (but not 72Hz) for the native resolution of 1280x1024.

1.Double click the Display icon in Control Panel.

2.From the Display Properties window, select the Settings tab and click the Advanced button.

3.Select the Adapter tab, and select an appropriate refresh rate to match one of the applicable factory modes as listed in the specification table.

4.Click Change, OK, then Yes.

5.Close the Display Properties window.

19 How to adjust the screen refresh rate

171 How to set the picture optimization

The easiest way to obtain an optimal display is to use the i key function. Press thei key to optimize and adjust the screen settings automatically for you. Refer toHow to adjust your monitor for button locations and functionality.

If you wish to, you can always adjust the screen settings manually using the buttons on the monitor panel. 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 the Enter key to access the monitor On-ScreenDisplay (OSD) menu.

3.If you notice a vertical noise, press the WorXkeys to select Geometry and press the Enter key. Then press theWorXkeys to select Pixel Clock and press the Enter key again. Then, press theWorXkey to adjust the monitor until the noise disappears.

4.If you notice a horizontal noise, press theWorXkeys to select Geometry and press the Enter key. Then press theWorXkeys to select Phase and press the Enter key again. Then, press theWorXkeys to adjust the monitor until the noise disappears.

To make sure the i key function performs well, you have to select one of the supported modes. If thei key does not work properly and the NON PRESET MODE message is on the OSD, it means you are not using one of the supported modes. Please set your monitor to use one of the supported modes as listed at the end of this manual.

Frequently Asked Questions (FAQ)

The image is blurred:

Read theHow to adjust the screen resolution section, 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 How to adjust the screen refresh rate section 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 abuilt-inbooster.

Does the blurring only occur at resolutions lower than the native (maximum) resolution?

Read the How to adjust the screen resolution section. 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.

Modes not listed in the table may not be supported. For an optimal picture, we recommended you choose a mode listed in the table above.

There are 22 available modes that are compatible with Windows.

Image disruption may occur as a result of signal frequency differences from VGA cards which do not correspond with the usual standard. This is not, however, an error. You may improve this situation by altering an automatic setting or by manually changing the phase setting and the pixel frequency from the “Geometry” menu.

If you switch off the monitor, interference lines can occur on your screen. But do not be concerned about this, as it is normal.

To extend the service life of the product, we recommend that you use your computer's power management function.

*Response Time: The time it takes to switch a pixel off and then on and then off again (or from black to white and back to black). A low response time is desirable for the display of moving images without ghosting. The Response Time quoted for many LCD monitors is specific to transitions from black to white and back again, it does not specify the time required to switch between the many gray levels or colors that make up an image.

Gray to Gray or GTG Response Time: “Real world” video content contains a combination of grayscale images. It generally takes longer for a pixel to transition to an intermediate level of intensity (i.e. a gray or color level) than it does for it to turn completely black or completely white. For example the "Gray to Gray response time" of an LCD panel may generally be 30 to 40 ms while the "Response Time" is 12 ms . BenQ's AMA technology greatly reduces the GTG response time so moving parts of the image are clearer, no matter what the image content is. With Advanced Motion Acceleration (AMA), the average GTG response time can be as low as 8 ms.
