Chapter 2: Overview  
2. Overview  
2.1 Introduction  
The DVI Splitters broadcast the same video with audio signals from one video (and  
audio) signal source to two, four, or eight DVI compatible ports. To expand the  
broadcast significantly, you can cascade several splitters together.  
Depending on the length and cable quality, this fully HDCP-compliant splitter  
supports DVI display resolutions of up to Full HD (1920 x 1080)/WUXGA (1920 x  
1200)/UXGA (1600 x 1200), and is also Blu-ray ready. You don’t need to install  
software or interface cards. Just connect the cables, power up the system and it will  
duplicate video images for multiple monitors with excellent clarity. The 4- and  
8-port splitters can also be rackmounted.  
Use the spitters for presentations, exhibits, demonstrations, trade shows, monitor  
testing and burn-in, business meetings, news, stock tickers, airline/train/bus  
schedules, and retail stores.  
2.2 Features  
• Duplicates one video input to multiple DVI outputs.  
• Saves power when signal input is lost.  
• You can cascade operation for increased signal outputs.  
• Provides crisp, clear, video images.  
• Supports EDID, HDCP, and is Blu-ray ready for high definition display.  
• Supports DVI display resolutions of up to UXGA (1600 x 1200), WUXGA (1920 x  
1200), and Full HD 1080p (1920 x 1080).  
• Rackmountable (AVSP-DVI1X4 and AVSP-DVI1X8 models only).  
• LED indicators for signal activity monitoring  
• Accurately and reliably reproduces digital video signals without attenuation and  
distortion.  
• Installs in seconds.

Chapter 3: Installation  
3. Installation  
WARNING: Before installation, power off all devices that will be connected to this  
system.  
• Make sure that all devices you will connect are properly grounded.  
• Place cables away from fluorescent lights, air conditioners, and machines that are  
likely to generate electrical noise.  
Use one DVI male-to-male cable to connect a video source to the video splitter Input  
(SOURCE). Connect multiple monitors or TVs to the video splitter’s output ports.  
Plug a set of audio jacks from the speaker to the splitter’s audio port.  
Use a DVI-to-HDMI adapter that combines digital video (DVI) and digital audio into  
HDMI to seamlessly integrate into your computer systems or modern home theater.  
Simply connect the optional DVI-to-HDMI adapter(s) to the output side of the  
splitter, and then connect the HDMI display or projector to the HDMI output of the  
DVI-to-HDMI adapter.  
The adapter will convert the digital audio onto the digital video signal to generate  
the HDMI signal.  
Turn on your video source only after you've made all the connections.

Chapter 3: Installation  
NOTE: Connect at least one monitor to the splitter before powering on the source  
device.  
NOTE: Connect the splitter to the computer before powering on the computer.  
NOTE: Use an HDCP-compliant display to connect the splitter to the HDCP video  
source.  
NOTE: Each output port on the unit is required to apply the same connection  
pattern whenever a DVI-to-HDMI (or HDMI-to-DVI) adapter is used for HDMI  
(or DVI) signal conversion between the unit and the HDMI (or DVI) display.  
Mixed (HDMI and DVI) output connections may cause signal degradation.  
Signal degradation, harmful interference, or equipment malfunction are less  
likely to occur if absolute connection consistency is used.  
Figure 3-4. Do NOT use the mixed connection pattern shown in this diagram.  
Blu-ray Ready  
The splitter supports high-definition video such as DVD or Blu-ray and multichannel  
audio, and carries the best signal from the source to displays; the high bandwidth  
enables transmission of large amounts of information at a very high rate of speed.

Chapter 3: Installation  
Blu-ray uses a blue-violet laser to read and write data, while current optical disc  
technologies such as DVD, DVD R, DVD RW, and DVDRAM rely on a red laser to  
read and write data. Blu-ray uses a blue-violet laser (405 nm) that it has a shorter  
wavelength than a red laser (650 nm), which makes it possible to focus the laser  
spot with even greater precision. This enables data to be packed more tightly and  
stored in less space, so it’s possible to fit more data on the disc even though it’s the  
same size as a CD/DVD.

Chapter 4: Operation  
4. Operation  
The quality of the output signal depends largely upon the quality of the video  
source, cable, and display device used. Low-quality cables degrade the output signal  
causing elevated noise levels. Use the proper cable and make sure the display device  
is capable of handling the resolution and refresh rate selected. Interference from  
nearby electrical devices can adversely affect signal quality.

Appendix: Troubleshooting  
Appendix. Troubleshooting  
A.1 Symptoms, Possible Causes, and Solutions  
Symptom: Video does not display on some ports.  
Possible Cause: DVI specification of the source devices doesn’t match the DVI  
specification of DVI cable and/or the DVI display device.  
Solution #1: There are three DVI standards: DVI-I, DVI-D, and DVI-A. Make sure  
that DVI specifications of the source devices, cables, and monitors all match.  
NOTE: Some monitors can support multiple DVI signals.  
Solution #2: Make sure the splitter was connected to the source computer before  
powering on the computer.  
Symptom: Erratic behavior  
Possible Cause: The splitter might not receive enough power.  
Possible Solution: Make sure the power adapter attached to the splitter matches  
the system specifications, and that it is functioning properly.  
Symptom: Not receiving picture or sound.  
Possible Cause #1: Wrong installation process.  
Solution #1: The video splitter requires at least one monitor connection before  
powering on the source device.  
Possible Cause #2: The signal source may require a display device that is HDCP  
compliant.  
Solution #2: Check if the display monitor is HDCP compliant. HDCP prevents the  
transfer of digital content to unauthorized HDMI devices.  
Possible Cause #3: The display monitor is added to the unit by hot-plug, but the  
video source may not support hot-plug.  
Solution #3: Check if the video source supports hot-plug. If it doesn’t, shut down  
the source device and reboot it again.

Appendix: Troubleshooting  
Possible Cause #4: The attached devices are not well connected.  
Solution #4: Make sure you connected your components correctly.
