BlueRigger 4K HDMI Splitter 1 In 2 Out

The BlueRigger 4K HDMI Splitter takes one HDMI source and sends it to two displays at the same time. Both screens show the same picture: this is a splitter, a distribution device, and its job is mirroring one programme onto two displays rather than showing different content on each. It supports resolutions up to 4K at 60Hz, provides Auto, Copy and Fixed EDID modes to manage how the source and the displays agree on a format, and runs from 5V USB power. It suits the common situations where one player, console, PC or set-top box needs to feed a television and a projector, or two screens in different parts of a room, simultaneously.

Key features

• One HDMI input and two HDMI outputs
• Mirrors the same source image to both displays simultaneously
• Supports up to 4K at 60Hz
• Auto, Copy and Fixed EDID modes for display compatibility
• Powered by 5V via USB
• Distribution device; not an input switch or desktop extender

One source, two screens, same picture

A splitter exists because HDMI outputs are single-destination: a source has one socket, and without distribution only one display can be connected. The BlueRigger splitter receives the signal, and actively outputs it on both ports, so a Blu-ray player can feed the TV and the projector in the same room, a console can drive a television and a capture or monitoring display, or a presentation laptop can show on a lectern monitor and the main screen together. Because the device is powered, it is an active distribution amplifier rather than a passive cable Y-split, which cannot reliably drive two displays. What it deliberately does not do is extend a computer desktop across two monitors as separate workspaces; both outputs always carry the identical image.

EDID modes: Auto, Copy and Fixed

When a source connects to a display, the display reports its capabilities in data called EDID, and the source chooses a format both can handle. With two displays of different capabilities on one splitter, that negotiation needs managing, and the three modes are the tools for it. Auto lets the splitter settle on a format the connected displays can commonly accept. Copy takes the EDID of the display on the first output and presents that to the source, which is useful when one main display should set the standard. Fixed presents a preset EDID from the splitter itself; the manufacturer’s reference for Fixed mode is 4K at 30Hz, so treat Fixed as a compatibility fallback for stubborn combinations rather than the mode for maximum performance. Choosing the right mode is the difference between a two-display setup that simply works and one that negotiates down or drops out.

Power and setup

The splitter takes 5V power over USB, so it can run from a USB port on the source device, the display or a standard USB power adapter, without needing a dedicated mains brick of its own. Setup is a short sequence: connect the source to the input, connect both displays to the outputs, connect the USB power, then switch the system on and select the EDID mode that suits your displays. Use sound, reasonably short HDMI cables on a 4K 60Hz chain, since the splitter can only distribute the signal quality it receives, and confirm both displays show the picture before the installation is closed up.

Splitter, switch or matrix: choosing correctly

These devices are often confused. A switch does the opposite job to a splitter: several sources into one display, selecting which one is shown. A matrix combines both functions and routes any source to any display independently. A splitter, like this BlueRigger, is the correct and simplest choice when the requirement is exactly one source shown on two displays at once: showroom screens, a TV and projector pair, classroom and training setups, places of worship, and retail or signage points where the same content must appear in two places. Count your sources and displays first; if the numbers are one and two, this is the device category you want.

For mirroring a 4K source onto two displays with sensible EDID control and simple USB power, the BlueRigger 4K HDMI Splitter 1 In 2 Out covers the requirement in a single compact unit.
