How to use a black box 4-port splitter

A Black Box 4-port splitter allows you to send a single video or audio signal to four displays or devices simultaneously by connecting the input source, output devices, and power, with optional adjustments for long cable runs.

Step-by-Step Setup

1. Unpack and Inspect Ensure your package includes the splitter, power adapter, and any optional accessories like HDMI or VGA cables. Check for damage and contact Black Box support if anything is missing or defective . 2. Connect the Input Source

• For HDMI splitters, connect your video source (e.g., Blu-ray player, computer) to the HDMI input port using a male-to-male HDMI cable .
• For VGA/XGA splitters, connect the computer or video source to the VGA input (HD15) port . 3. Connect Output Devices
• Plug each display or monitor into the splitter's output ports. For HDMI, use standard HDMI cables; for VGA/XGA, use HD15 cables .
• If some monitors are located far from the splitter (over 150 feet for VGA/XGA), use the boosted outputs or enable cable length compensation switches if available . 4. Connect Audio (if applicable)
• If your splitter supports audio, connect the audio input from your source and link the audio outputs to speakers or audio devices . 5. Power the Splitter
• Connect the included power adapter to the splitter and plug it into a mains outlet. The power LED should light up to indicate the unit is active . 6. Verify Signal
• Turn on your source and displays. Check that all output devices are receiving the signal. LEDs on the splitter may indicate active ports . 7. Adjust for Long Cables (VGA/XGA only)
• Use the dip-switches or compensation settings on the splitter to boost signals for long cable runs to prevent fuzzy or blurry images .

Troubleshooting Tips

• No signal on some outputs: Ensure cables are securely connected and the source is powered on.
• Blurry or ghosting images: Adjust cable length compensation switches or use higher-quality cables for long runs .
• Audio issues: Verify audio cables are correctly connected and the source is outputting audio.
