1.1 Video Input/Output
If possible, always use DVI output from your computer’s video card and DVI input to
a monitor. This provides the optimum video signal. If you use a VGA output from your
graphic source, the DVI-KVM Local unit must digitize the signal prior to transmission.
Similarly, if your remote TFT screen uses a VGA input, it must digitize the signal from
the Remote unit. In both cases, the built-in video processors must determine the
resolution and pixel phase for an optimized digitization. Your DVI Extender allows
you to optimize the video signal manually or automatically using its on-screen utility
(see Chapter 4). If you are using a VGA input to a TFT monitor, please follow the
manufacturer’s instructions.
You may have several possible options for video source output/monitor input. If this
is the case, for the optimum video quality, please select the highest ranked available
combination from the following table:
Video Quality Local Unit input Remote Unit output
1 DVI DVI
2 DVI VGA
3 VGA DVI
4 VGA VGA
