IV. GETTING THE BEST RESULTS
Manyfactorsinuencethequalityofadigitalvideosignalinanyapplica-
tion. When additional interconnects are put into the system, the pos-
sibility for signal degradation arises. Below are some things to keep in
mind in order to ensure the best unit performance:
• Output source device - The quality of the output signal will depend
largely upon the type and quality of source device used. For instance,
some DVD players just perform better than others.
• 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.
• 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-4141, the overall cable distance should
notexceed10Mwithoutproperamplication.
• Connection cables - When using the DVI + HDCP 4x1 Switcher, the
highest quality cables should be used. Using DVIGear’s Super High
Resolution DVI cables will ensure the best possible signal between the
source and the display.
• Interference from nearby electrical devices - These can have an ad-
verse effect on signal quality. For example, an older computer monitor
oftenemitsveryhighelectromagneticeldsthatcaninterferewiththe
performance of video equipment in its proximity.

VI. CONNECTING THE HARDWARE
Prior to connecting the unit, ensure that all devices have been
powered off.
1) Connect your DVI display to the switch’s DVI output with a high-
quality cable
2) Connect your four (4) DVI sources to the switch’s inputs using a
high-quality 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 all source and display devices.
V. OPERATING THE UNIT
It is possible to select the input device you wish to access in two ways:
using the front panel push button or via the enclosed remote control
unit.
1) Front Panel Push Button Selection:
• The front panel push button is used to select the source to be dis-
played on the screen. Pressing the button during normal operation will
cause the input devices to be toggled through.
2) Remote Control Selection:
• The input device may selected via the included remote control by
pressing the appropriate button (“1” for the source on input 1 and “2”
for the source on input 2 and so on).
Note:IfyouhaveaproblemwiththeIRcontrolconictingwithother
devices,theremoteallowsuserstocongurefour(A,B,C,D)alternate
combinations of IR codes. To change, press and hold an IR code but-
ton for 2 seconds.

VIII. TROUBLESHOOTING
If the switcher does not appear to be functioning, make certain that all
of the DVI connections are securely attached to the unit with all appro-
priate screws in tight. Secondly, verify the functioning of all DVI devices
(sources and displays) by connecting them with a short (6ft or less) DVI
cable. If the signal is present under those conditions, ensure that the
connections are made fully and that the power indicator light is clearly
lit. Finally, make sure that the overall cable distance does not exceed
10M(approx.33ft)withoutproperamplication.
