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 FP72E/T721 is achieved with a resolution of 1280 x 1024. 
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. Image blurring across 
pixel boundaries can occur with the interpolated resolution depending upon the image type and 
its initial resolution.
To take full advantage of LCD technology you should select the native resolution setting of 
1280 x 1024. 
1. Open Display Properties and select the Settings tab. 
Yo u  c a n  o p e n  Display Properties by right-clicking on the Windows desktop and selecting Properties 
from the pop-up menu.
2. Use the slider in the ‘Screen area’ section to adjust the screen resolution.
Select the recommended resolution of 1280 x 1024 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 Ye s. 
4. Close the Display Properties window.

							22  How to adjust the screen refresh rate  
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: 
Supported PC Timings on page 37
You can choose 60, 70 and 75 Hertz, (but not 72Hz) for the native resolution of 1280 x 1024. 
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 Ye s. 
5. Close the Display Properties window.

Picture optimization 
The easiest way to obtain an optimal display from an analog (D-Sub) input is to use the i key 
function. Press the 
i key to optimize the currently displayed image to the screen. 
When you connect a digital video output using a digital (DVI) cable to your monitor, the 
i key and 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 (1280 x 1024) when you use the i key 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 the 
i key on the monitor.
3. Press the MENU key to access the monitor On-Screen Display (OSD) menu.
4. Use the 
W or X keys to select DISPLAY and press the ENTER key to enter the menu.
5. If you notice a vertical noise (like a curtain effect-shimmering of vertical lines), press the 
W 
or 
X keys to select Pixel Clock and press the ENTER key. Then press the W or X keys to 
adjust the monitor until the noise disappears.
6. If you notice a horizontal noise, press the 
W or X keys to select Phase and press the ENTER 
key. Then press the 
W or X keys adjust the monitor until the noise disappears.
