HOW TO ADJUST THE PICTURE
5
The fi rst step in adjusting the video quality is to display text and a graphic on your monitor
(i.e. desktop icons). Then set your computer to the resolution that you will be using most
frequently. The dip switches are used to set the focus and sharpness of the picture to the
best possible setting. Set the dip switches to the settings that are recommended for the
different lengths of CAT5 cable (see chart below). Verify that the picture quality is to your
satisfaction. If the recommended setting does not produce a great quality picture, try using
a different dip switch setting. The trim pod next to the VGA connector on the VGA RS232
Extender-R allows brightness adjustments for video.
