INTRODUCTION
The Atlona AT-DVI-41A is 4 inputs and 1 output DVI Switcher with Stereo Audio. The switcher is designed to route up
to 4 x DVI sources with Audio to a single display. The DVI-41A is capable of passing extremely high resolutions up to
1920x1200 or 1080p. Each input is featured with a built-in repeater which will help to keep the signal quality the same
as it was originally.
The DVI switcher is fully HDCP compliant, therefore could be used along with HDMI sources, DVI/HDMI adapters or cables
will be required.
The Atlona 4x1 DVI Switcher could be controlled though IR remote, RS232 port or manually via buttons selection on the
front panel of the switch.
Note: For applications where customer would need the computer to sense a monitor at all the time even when switcher is switched
to a different computer, we recommend to use our EDID Recorder, AT-DVISync. User would require 1 x DVISync per computer.
