Fine-Tuning the Image Settings
Once the radio link has been established, and the monitor attached to the receiver is displaying
computer generated video, some fine-tuning of the video settings may be desired. This fine-tuning
should only be necessary the first time that a LongView Wireless transmitter is used with a
particular computer; settings, once adjusted, are saved in the transmitter unit.
A mouse or keyboard driven menu, called the On-Screen Display (OSD), enables you to perform
these adjustments. The LongView extender OSD allows you to use an Auto Setup feature to adjust
the image settings, or enables you to manually adjust any of the individual image settings. New
settings may be temporarily or permanently saved.
Main menu options
The LongView Wireless extender Main menu has two options- Auto Setup and Link Status. The
Auto Setup checks the video parameters for your source computer and then automatically
optimizes the video quality portrayed on your monitors. The Link Status indicates the signal
strength of the wireless connection between your LongView Wireless transmitter and receiver.
Advanced menu options
The LongView Wireless extender OSD Advanced menu allows you to fine-tune the video settings
that were established with the Auto Setup function. You may tune the horizontal and vertical
position of the video monitor window, as well as adjust the brightness and contrast of the video
