The splitter then “duplicates” the signal coming from your media device – and sends it to your two outputs. So you can watch the same stream on two TVs, a TV and a projector, and every other example you can think of. If you're looking for a thoughtfully designed HDMI switcher with a premium look and feel, the Zettaguard 4K is worth some consideration. Our reviewer tested it for weeks and thought the 4K content she streamed on her PC looked great, with the HDR coloring making the videos pop. The advantage of using HDMI ARC or eARC over an HDMI splitter is that it allows you to take advantage of Consumer Electronic Control or CEC. This allows you to use one of your device’s remotes to control all of your devices. It also synchronizes your devices so that they all have one master volume. Active HDMI Splitters But if you want to connect 4K devices to your 4K TV – your HDMI switcher has to support 4K, otherwise you’ll only get Full HD (1080p).

This also comes down to the HDMI version on the switcher. All switchers will support HDMI 1.4, but if you want 4K, you need the switcher to support HDMI 2.0a, or preferably HDMI 2.1. HDMI is a digital signal and won't degrade in the same way as older analog signals, even with the addition of a switcher. If you are experiencing a notable loss in signal quality, it may be due to a faulty one from your switcher or a damaged cable. And to top it all, it has an S/PDIF port, if you want to connect it to a digital audio device (and bypass the HDMI audio). With audio, for instance, the voltage of the signal directly translates to how far the speaker cone is pushed from its resting position and the changes in voltage create the motion of the speaker cone. This means more voltage equals louder sound.

HDMI Splitters: A Buying Guide

But if you just want a splitter that's reported to work for mirroring your video, with a high probability of working, keep reading. This box has eight inputs and a single output to accommodate the largest home and professional theater setups. If you know your display and video source are HDCP-compliant, consider just getting an HDCP-compliant HDMI cable. HDCP-Compliant HDMI Cable: 8K HDCP 2.3-Compliant HDMI Cable For the first spot on our list, we have this OREI HDMI Splitter which comes in two design variations. It also comes in three bundle options that you can opt for as per your preference. It supports HDMI 2.0, allowing you to get a maximum resolution of 4K.

The GANA HDMI Switcher only supports video up to Full HD (1080p), and doesn’t come with a remote control – but it compensates with an excellent price point. It doesn’t require an external power supply and works well with power from the HDMI devices, and it even comes with a gold-plated HDMI cable. That’s where an HDMI splitter comes in – it’s a small box that lets you plug in one “Input” device – that’s your streamer/ DVD Player/etc.’– and connect TWO (or more) screens to the “Output” side, all via HDMI cables.While many splitters and switches don’t require an external power source, others do. Be sure you’ll have an available outlet if that’s the case. How We Selected That’s exactly what this TESmart splitter does – with added support for the most recent HDCP standard (2.2 – so it should be suitable for Sky Q), as well as Dolby Atmos and several other advanced audio formats (though the splitter is just a pass-through – you still need a device that can interpret these audio signals). As previously mentioned, when you split any electronic signal, the resulting signals will be weaker than the original. Splitting it more than twice will make the signal too weak. Further, a weakened signal, even one that is good for short lengths, may be more susceptible to interference over longer runs of cable. A small box that sits next to your telly, an HDMI switcher connects to an available port on your TV. Then, you connect all your other HDMI-based devices to the switcher itself, and by pressing a button (or using a remote, on some switchers), you can switch between the devices without connecting and disconnecting their cables over and over again.
