Product Information

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 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. This box has eight inputs and a single output to accommodate the largest home and professional theater setups.

Because the digital signal depends only on frequency and not voltage, reduced power does not translate to muffled sound or color-shifted picture. This is why you shouldn’t have to worry about using a passive HDMI splitter for short cable runs. On the other hand, an HDMI switch manages multiple source inputs to transmit to a single output (most receivers act like HDMI switches). Thus an HDMI splitter will transmit to all available channels while an HDMI switch will only transmit to one. How Does an HDMI Splitter Work? It supports 4K at 30Hz, which is good for most uses, except for 4K gaming – so it’s not a good fit for the PS4 Pro, PS5, and other 4K gaming consoles.

First, it’s a switcher with two input ports, so you can connect two media devices (streamer, DVD player, etc’) and switch between them (with a button, or with the supplied remote control). But if you just want a splitter that's reported to work for mirroring your video, with a high probability of working, keep reading.

An HDMI Splitter is used to connect ONE DEVICE to two or more TVs (or other screens/projectors), by duplicating the stream. You may want to consider the following things before purchasing an HDMI splitter as it may alter your desicion. Copy protection and HDCPOne of the more common uses of an HDMI switcher is picture-in-picture, allowing you to watch two video sources simultaneously. If PiP functionality is a must for you, but 4K isn't, we can recommend the Orei HD-201P. This switcher excels at advanced PiP (again, only in HD and specifically the 1080p/1080i formats) and supports a whole bunch of advanced audio formats, so if you've got a home cinema setup, you're good to go, with support for PCM2, 5.1, and 7.1 surround sound, Dolby 5.1, and DTS 5.1. This is another niche product, but like above, we're glad it's available. An HDMI cable has 19 wire pairs that terminate in the same number of pins on the HDMI plug. Each of these wires transmits different information electronically via digital signals. This includes not only audio and visual data but also information about the specific devices and commands you might find on a remote control. 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).
