Adjusting the screen resolution

Due to the nature of liquid crystal display (LCD) technology, the picture resolution is always
fixed. For the best display performance, please set the display to its maximum resolution that is
the same with the monitor aspect ratio. 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 find out the monitor aspect ratio and native resolution of the purchased model, please check the Specification
on the website.

• To take full advantage of LCD technology you should select the native resolution setting of your PC screen as
described below. Be aware that not all PC video cards provide this resolution value. If yours doesn't, check
with the video card manufacturer's website for an updated driver for your particular model PC video card
which supports this resolution. Software video drivers are often updated and available for new hardware video
resolutions. If necessary, you may need to replace and update the PC video card hardware to be able to
support the native resolution of the monitor.

• Depending on the operating system on your PC, different procedures should be followed to adjust the screen
resolution. Refer to the help document of your operating system for details.

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 (maximum resolution) 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.

If your input source does not provide an image which is the same with the monitor aspect ratio,
the displayed image may appear stretched or distorted. To maintain the original aspect ratio,
image scaling options can be found in the “Display Mode” adjustment. See the user manual for
more information.

Adjusting 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.

Depending on the operating system on your PC, different procedures should be followed to adjust the screen
resolution. Refer to the help document of your operating system for details.

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.
