ACS253A-CT
Quick Setup Guide
QS1. Video Input/Output
If possible, always use the 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 graphics source, the ACS253A 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 enables 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:
Table QS-1. Video Input and Output
Video Quality Local Unit Input Remote Unit Output
1 (high) DVI

2 DVI VGA
3 VGA DVI
4 (low) VGA VGA
QS2. Local Video Output
IMPORTANT: The local Video Out always carries the same signal your graphics card generates—this is opposite of the remote
out. The local unit does provide any signal translation for the local output.
This means, if you connect the local unit to a VGA graphics card, the local Video Out will alway carry VGA
signals, whether you connect a VGA or DVI screen to the remote unit. And the reverse is true: if you connect
the local unit to a DVI graphics card, the local Video Out will always carry DVI signals, whether you connect a
VGA or DVI screen to the remote unit.
The following table shows all possible input/output combinations:
