d. To switch from Mirror mode to Extended mode, you can do one of the following:
v Click Extend to and select the position of the external monitor.
v Click Extended to retrieve the last settings of the Extended mode.
e. It takes a few seconds to change from one mode to another.
3. To change the screen resolution of the external display, select Screen Resolution and one of the
options listed by the application. For example, selecting 1280 x 1024 means that the video port will
provide video output of 1280 pixels by 1024 pixels. In addition to the resolutions that are supported
by the USB Port Replicator, the list also includes the resolutions supported by the external monitor, or
the default resolution if the monitor does not provide the information related to the supported
resolutions.
4. To change the color quality of the external display in the Extended mode, select Color Quality and
choose either Medium or Highest
5. To rotate the view of the external screen, select Screen Rotation and Rotated Left, Rotated Right, or
Inverted Upside-Down. Select Normal to switch to the normal view.
Note: The refresh rate of the external monitor can only be modified through the standard interface of
the operating system and not through the utility provided with the USB Port Replicator.
6. You can select Off to turn off the video signal from the USB Port Replicator without using the front
button. To turn the video signal on, select either the Extended or the Mirror mode. The video signal
output also can be enabled by pressing the DualView button on front of the unit; the video settings
that were in effect before disabling the video output will be retrieved.
7. If you use multiple USB Port Replicators with a single notebook computer— for example, one at work
and one at home— the video settings for each USB Port Replicator are saved when you disconnect the
notebook computer. Therefore, you can set your USB Port Replicator at work to the Extended mode
while configuring the one at home to the Mirror mode. The appropriate settings are retrieved each
time you use the USB Port Replicator with your notebook computer.
