Product Information

In the case of a single source outputting to an audio and a visual output, an HDMI splitter should be your last resort. A far more preferable way to connect the devices is to take advantage of HDMI ARC or eARC. This will require your display device and your audio device to both have an HDMI ARC or eARC port. This will usually be labeled as such next to the port itself. You can use an HDMI switcher with two HDMI outputs to send the same HDMI signal to two TVs or a video projector and TV, but you can use an HDMI splitter if you don't need a switcher. But if you just want a splitter that's reported to work for mirroring your video, with a high probability of working, keep reading. But other than that, the modern Playstations are very fussy about the switchers (and even HDMI cables) they “agree” to work with. I believe this is mainly due to issues with the HDCP copy-protection standard and power issues.

Manual Switching with a Remote: You still have to switch between the connected input ports manually, but at least you don’t have to get up from the sofa, as you have an IR remote that controls the switcher. After establishing a verified connection, HDCP encrypts the signal to prevent unauthorized recording of the content. HDCP's encryption makes split video unwatchable. Unfortunately, this arrangement also prevents content owners from viewing their own content sometimes. There are a few exceptions – for example, products that can function as both a Splitter AND a Switcher (so all their ports can serve as either Input or Output), and products that let you Switch different devices and then Split them to multiple screens.Orei also fared well in our round-up of HDMI Switchers, and here they are again taking the splitter market by storm. This unit will easily duplicate a single signal to up to four 4k displays (it comes in both two and four output models)

Manual Switching: You switch between the HDMI input ports by pressing a button on the switcher itself. For passive HDMI splitters, that is the long and short of it. For active HDMI splitters, there is another step. They even do a model that will dispense with HDMI and output over ethernet too, which is sometimes used in commercial settings. Auto-switching doesn’t always work (as is the case with almost all the HDMI switchers), but other than that, manual switching is very swift, although some devices – the Google Chromecast in particular – sometimes “snatch” the focus when they’re supposed to be idle.If you want to share a display or projector with many video sources, you need the best HDMI splitter or switch. As most of us need an easy way to project our work on the many, big screens, I’ll list down selected best 4K HDMI splitters. What to look for before buying your an HDMI splitter: Getting the perfect HDMI switcher for your needs is not just a question of quality or even price – it also depends on which features you want and what exactly you’re planning to connect to your TV – now and in the future. Yes, some HDMI splitters outperform others depending on how you plan to use them. Active HDMI splitters are best suited for sending signals at a long distance. Whereas a passive HDMI splitter is better suited for short distances. An HDMI Splitter is meant to connect ONE DEVICE to two or more TVs (or other screens / video projectors). It delivers 4K and 2K content at 30Hz and 1080p content at 120Hz. It also supports most audio formats, and is equipped with built-in vents to prevent it from overheating.

Most 4K HDMI Splitters support 30Hz, which is enough for most regular video uses – it means you’ll see up to 30 frames per second. 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. Automatic switching: The switcher senses which device is active at the moment (your Fire TV is sending a video signal, for example), so it automatically switches the output on your TV screen to that active device. While it sounds convenient, this automatic switching is far from perfect, and the switcher will often get confused with devices that “snatch” the port even when they’re seemingly idle. This is also important when you have a subscription to a streaming service that limits the number of simultaneous streams you can watch. For example, if you have the Standard Netflix membership, you can only watch up to two streams at once. HDCP’s aim is to protect video feeds from illegal copying, and you need to make sure the HDMI splitter you’re buying supports this standard, otherwise most devices you connect to it won’t be able to broadcast anything to your screens.The runner-up on our list is this Avedio Links HDMI Splitter, which supports a 4K resolution, so you get a crisp, artifact-free display. It has three input ports and one output cable. The body is also made using aluminum alloy, making it resistant to corrosion and overheating. The high build quality impressed customers a lot.
