B. Choosing the best resolution
Due to the nature of LC display technology, the resolution is always fixed. For the FP791 this is a
resolution of 1280x1024. This is called the "Native Resolution", which also represents the maximal
resolution. Lower resolutions are displayed on a full screen through an interpolation circuit. Flaws
do occur with the interpolated resolution compared to the native resolution. If you want to have all
the advantages of LCD technology you must use the native resolution. Using Windows 95/ 98/
2000/ XP you can change the resolution as follows:
1. Double-click the "Display" icon in the Control Panel.
2. From the "Display Properties" window, select the "Settings" tab. You can alter the resolu-
tion by using the slider on the right-hand side.
3. Select a resolution of 1280x1024. Then click "Apply.".
English 32
4. In the subsequent windows, press "OK" and "Ye s "
5. You can now close "Display Properties".

C. Refresh Rate Selection
There is no need to choose the highest possible refresh rate on an LC display. It is not technically
possible for an LC display to flicker. Even at a refresh rate of 60 Hz you will get an absolutely flickerfree image. More important is that you make sure that you use one of the factory modes. In contrast to a modern CRT monitor, which is a multiscan monitor, the LC display is a multi-frequency
monitor. This means, the best results are only obtained by using the factory modes. You will find a
table with the factory modes in this user's guide. These modes, for example, are 60, 70 and 75
Hertz, but not 72Hz, for the native resolution of 1280x1024. In Windows 95/ 98/2 000/ XP you
can change the refresh rate as follows:
1. Double click the "Display" icon in the Control Panel.
2. From the "Display Properties" window, select the "Settings" tab. Click the "Advanced..."
button in the bottom right corner.
English 34
BenQ LCD Color Monitor User's Guide
3. Select the "Adapter” tab. The refresh rate selection field is located in the center at the bottom of the window.
4. Choose a refresh rate from the table with the factory modes, which can be found in the user’s
guide, and select this in the settings field.
5. In the subsequent windows press "Change", "OK" and "Ye s ".
6. You can now close "Display Properties".
English 35
BenQ LCD Color Monitor User's Guide
D. Picture Optimization
The easiest way to obtain an optimal display is to use the ikey function. Press the “ikey” on the
control panel and the monitor will adjust automatically.
If you are still not satisfied with the result, you can still adjust the image manually.
1. Run the test program auto.exe from CD-ROM; this is the best way to observe possible
changes. You can 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 emerges.
2. Press on control panel to access OSD.
3. If there is vertical noise observed, press
4. If there is horizontal noise observed, press
key. Then press

To m a ke s u re t he “iKey” function perform well, you have to use one of the supported modes. If the
“iKey” 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 computer to use one of the
supported modes. You will find a list of supported modes in this manual.

Troubleshooting
Frequently Asked Questions (FAQ)
✓ The image is blurred:
☞ Read the Installation/Adjustment 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 Installation/Adjustment 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 a built-in booster.
☞ Does the blurring only occur at resolutions lower than the native (maximum) resolution?
Read the Installation/Adjustment section. Select the native resolution.
✓ Pixel errors can be seen:
☞ One of several pixels are permanently black, one or more pixels are permanently white,
one or more pixels are permanently red, green, blue or another color.
Read the Pixel error rates section.
✓ The image has a faulty coloration:
☞ It has a yellow, blue or pink appearance.
On the monitor, press key and press or key to move to the “Recall” icon and
press key to enter “Recall” sub menu. Press or key to select “Color Recall”
and select “Yes” in “Color Recall” sub menu, then press key to recall to factory settings. 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 Supported operating
modes section.

hModes not listed in the above table may not be supported. For an optimal picture, we recom-
mended you choose a mode listed in the table above.
hThere are 22 available modes that are compatible with Windows.
hImage 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.
hIf you switch off the monitor, interference lines can occur on your screen. But do not be con-
cerned about this, as it is normal.
