HDMI Splitter QOLTEC Active 2‑output 4Kx2K 3.4 Gbps

QOLTEC Active HDMI Splitter 2-output 4Kx2K 3.4 Gbps duplicates a single HDMI source to two displays simultaneously while preserving video quality up to 4Kx2K. The device features active signal amplification to maintain stable transmission over connected HDMI cables and is designed for simple installation in home AV systems, small meeting rooms, retail displays and presentation environments.

Advantages

This HDMI splitter supports up to 4Kx2K resolution and provides a maximum bandwidth of 3.4 Gbps per link, enabling clear high-definition video on two screens at once. As an active splitter it amplifies and conditions the signal to reduce degradation over cable runs, improving compatibility with different HDMI displays. The compact form factor and plug-and-play operation simplify setup without requiring additional software or configuration.

Suitable for

• Home theatre systems for mirroring video from a set-top box, media player or streaming device to two TVs
• Business presentations where one source must be shown on two projectors or displays
• Retail and digital signage installations requiring the same content on multiple screens
• Small meeting rooms and classrooms that need duplicate output for audience visibility

Key specifications

• Video resolution support: up to 4Kx2K
• Per-link bandwidth: 3.4 Gbps
• Outputs: 2 HDMI outputs for simultaneous mirroring
• Signal type: Active amplification for improved signal integrity
• Compatibility: Works with standard HDMI sources and displays (HDMI video/audio)
• Installation: Plug-and-play, no driver installation required

How to use

Connect the HDMI source (for example a Blu-ray player, set-top box or streaming device) to the splitter's input. Use HDMI cables to connect each of the two HDMI outputs to the target displays. Power the splitter if an external power adapter is supplied or required, and switch on the source and displays. The device will mirror the source image to both connected screens with no additional configuration. If image or audio issues occur, check cable quality and length, and ensure displays support the resolution being output.

Usage recommendations

For reliable 4K performance, use high-quality HDMI cables rated for the required bandwidth and minimise cable length where possible. When connecting displays with different native resolutions, set the source device to a resolution supported by both screens to ensure consistent output. Avoid chaining multiple splitters; for larger multi-display setups consider dedicated distribution amplifiers or matrix switchers.
