Adjusting Video Settings - Lenovo 43R8770 - Enhanced USB Port Replicator User Manual

Adjusting Video Settings

For either the Mirror mode or the Extended mode, you can adjust one or more of the following video
settings. In the Mirror mode, the settings apply to both your notebook computer monitor and the external
monitor; in the Extended mode, you can set separate settings for your notebook computer monitor and
the external monitor:
v Resolution: refers to the number of pixels displayed on your screen horizontally and vertically. A
higher resolution means that you can see more of your image on the screen without scrolling or
panning.
v Color depth: defines the number of different colors that can be shown on the screen at the same time.
The greater the color depth is, the better the picture quality is.
v Refresh rate (also called vertical frequency): measures the speed that the entire screen is rescanned.
Higher frequencies reduce flicker because they light the pixels more frequently, thereby reducing the
dimming that causes flicker.
The table below displays the list of refresh rates supported at various resolutions and color depths for the
USB Port Replicator video output:
Resolution
640 X 480
800 X 600
1024 X 768
1280 X 768
1280 X 800
1280 X 960
1280 X 1024
1366 X 768
1440 X 900
1400 X 1050
To set up your video settings, follow the instructions below:
1. On your notebook computer, right-click the Lenovo Enhanced USB Port Replicator icon in the system
tray to activate the user window for configuring the settings of the video output of the USB Port
Replicator.
2. To change video modes, select the Extended or Mirror mode:
Click Extended to configure the external monitor in the Extended mode. The default setting for the
Extended mode positions the external monitor on the right side of the primary display.
Note:
a. The primary display corresponds to the notebook computer display unless it is configured
differently through the Display Properties window of the operating system.
b. In the Extended mode, you can select the position of the external monitor in relation to your
notebook computer display by clicking Extend to and making a selection from the displayed
menu.
c. In the Mirror mode, you cannot modify the resolution of the external monitor. The resolution is
automatically selected to better match the display resolution of the notebook computer connected
to the USB Port Replicator. To change the screen resolution of the notebook computer, click
Advanced to activate the Display Properties window of the operating system.
