What Is the JTD-3287 HDMI Splitter?

 

The J-Tech Digital JTD-3287 is a 1x2 HDMI splitter designed to duplicate a single HDMI input source onto two displays simultaneously. It supports resolutions up to 4K@60Hz (4:2:0), HDR, 3D video, and popular surround sound formats for a high-quality viewing experience.

Key Features

 

  • Duplicate one HDMI source to two displays simultaneously
  • Supports resolutions up to 4K@60Hz (4:2:0)
  • HDR and 3D compatible
  • Supports Dolby, DTS, PCM 2.0, and LPCM 7.1 audio
  • Automatic EDID management for stable compatibility
  • Compact plug-and-play installation
  • HDMI 1.4 and HDCP 1.4 compliant

 

Common Uses for a 1x2 HDMI Splitter

 

The JTD-3287 is ideal for:

  • Home theater systems
  • Gaming setups with dual displays
  • Sports bar and restaurant TVs
  • Conference room presentations
  • Retail digital signage
  • Classroom display duplication
  • Streaming and content monitoring setups

Because the splitter mirrors the same image to both displays, it's perfect for applications where identical content needs to appear on multiple screens.

 

What’s Included in the Box?

 

Inside the package, you'll find:

  • 1x JTD-3287 HDMI Splitter
  • 1x 5V/1A Power Adapter
  • 1x User Manual

 

 

What You Need Before Setup

 

Before installation, make sure you have:

  • HDMI source device (PC, gaming console, streaming device, cable box, etc.)
  • Two HDMI displays (TVs, monitors, or projectors)
  • Three HDMI cables
  • Power outlet for the splitter adapter

 

How to Set Up the JTD-3287 HDMI Splitter

 

 

Setting up the splitter only takes a few minutes.

Step 1: Connect Your HDMI Source

 

Connect your HDMI source device to the HDMI input port on the splitter.

Examples of compatible source devices include:

  • PlayStation or Xbox consoles
  • Streaming boxes
  • Blu-ray players
  • PCs and laptops
  • Cable or satellite boxes

 

Step 2: Connect Your Displays

 

Use HDMI cables to connect both output ports from the splitter to your TVs or monitors.

The splitter includes:

  • 1 HDMI input
  • 2 HDMI outputs

 

Step 3: Connect Power

 

Plug in the included 5V power adapter to power the splitter.

The power LED indicator will illuminate once powered on.

 

Step 4: Power On Your Devices

 

Turn on:

  1. Your HDMI source
  2. The HDMI splitter
  3. Both displays

The system should automatically detect and mirror the signal across both displays.

 

Understanding the Automatic EDID Function

 

One of the most important features of the JTD-3287 is automatic EDID management.

The splitter automatically copies the EDID information from connected displays to maintain stable compatibility. According to the manual:

  • If both displays support 4K, the splitter copies 4K EDID
  • If one display only supports 1080p, the splitter defaults to 1080p
  • If EDID cannot be read, the splitter defaults to 1080p

Why This Matters

This helps prevent:

  • No signal issues
  • Resolution mismatches
  • Flickering screens
  • Handshake problems between devices

For best results, using two displays with matching resolutions is recommended.

 

Supported Video and Audio Formats

 

Video Support

The JTD-3287 supports:

  • Up to 4K@60Hz (4:2:0)
  • HDR
  • 3D video formats
Audio Support

Compatible audio formats include:

  • PCM 2.0
  • DTS
  • Dolby Audio
  • LPCM 7.1 surround sound

This makes it suitable for both standard TV setups and surround sound entertainment systems.

 

Troubleshooting Tips

 

No Signal on One or Both Displays

Try the following:

  • Verify all HDMI cables are securely connected
  • Power cycle the splitter and displays
  • Test with shorter HDMI cables
  • Confirm both displays are set to the correct HDMI input

 

Resolution Drops to 1080p

This usually happens when one connected display only supports 1080p.

Since the splitter mirrors the signal, it will match the lowest common supported resolution between displays.

 

Flickering or Intermittent Signal
  • Replace low-quality HDMI cables
  • Avoid excessively long HDMI runs
  • Ensure the power adapter is properly connected
  • Test each display individually

 

The J-Tech Digital JTD-3287 is a simple and reliable solution for duplicating one HDMI source to two displays. With support for 4K video, HDR, immersive audio, and automatic EDID handling, it’s a great choice for home entertainment, business presentations, and digital signage applications.

Its compact design and plug-and-play functionality make installation quick and hassle-free, even for non-technical users.
