• Using Native Resolution - It is always best to set the output resolu-
tion of the source device to the native resolution and refresh rate of
the display device(s). This allows for the two units to work together in
the best fashion. Consult the owner’s manual for your display for more
information.
• Distance between the source and display devices - The length of cable
between the source(s) and display(s) should be minimized as much as
possible. When using the DVI-4121, the overall cable distance should
not exceed 15 meters (49 ft.) without proper signal management (e.g. DVI
Repeater
, or DVI Extender
).
• Connection Cables - For optimum performance, it is strongly suggested to
use DVIGear’s Super High Resolution™ DVI and HDMI cables.
• Interference from nearby electrical devices - Both electrical appliances and
electrical wiring can have an adverse effect on signal quality. Avoid that this
product is placed in close proximity to fluorescent light fixtures or appliances,
equipment, machinery that requires large amounts of AC Power as they can
emit very high electromagnetic fields that could interfere with the performance
of this product.
VIII. CONNECTING THE HARDWARE
Prior to connecting the unit, ensure that all devices have been powered
off.
1) Connect your DVI display to the switcher’s DVI output with a DVIGear Super
High Resolution™ cable.
2) Connect 2 DVI sources to the switcher’s inputs using a DVIGear Super High
Resolution™ DVI cable.
3) Plug the 9VDC power adapter in to the rear of the unit.
4) Plug the power adapter in to an AC socket.
5) Power ON the switcher first, then power ON the display - power ON the
sources last.
