What Is a HDMI Cable Splitter? 

Whether you are into technology or not, you may have come across the acronym ‘HDMI’ at some point in your life. HDMI stands for High-Definition Multimedia Interface and is what many modern day television or screen projectors use to display signals transferring both high definition audio and video over a single cable (typically known as a HDMI cable).

Now that you know what HDMI and HDMI cables are, you may be asking ‘What is a HDMI cable splitter’.

A HDMI cable splitter is a handy device that allows you to transmit a single HDMI source to multiple different displaying devices. They are simple, powerful, reliable and provide everything you need to send a singular HDMI signal. You can imagine the usefulness of such technology as if multiple displays need to be projected at one time, home theatre setups, education, information systems and training centres can benefit massively with this device. 

What Are The HDMI Cable Splitters’ Numerous Functionalities? 

The major benefit of incorporating a HDMI cable splitter is the ability to share HDMI signals between 2 – 8 (sometimes even more) devices.

How Do You Set Up A HDMI Splitter?

Installing a HDMI splitter is as simple as plugging a HDMI cable into your TV and desired device. Let’s imagine the following scenario to better explain how you set up a HDMI splitter:

You are currently in your bedroom with your sibling and have a games console and 2 TV’s in the room. You both want to watch Netflix on the games console on both TV’s but the console only has one HDMI port. How do you overcome this? 

All you need for this scenario is a 1×2 HDMI splitter and the HDMI cables to run out to your devices. The games console will plug into the HDMI splitter, and the HDMI splitter will plug into both televisions. Both televisions will get the same picture, full high definition and full surround sound audio that the games console sends out. 

In this example, you may have been confused with what ‘1×2’ means. In the world of HDMI splitters, they will be labeled in their name with the number of inputs to outputs. What this means is, the label will be separated by an “x”. So a “1×2” splitter will have one input (the games console) sent to two outputs (the two TV’s in the room).

Passive HDMI Splitters and Active HDMI Splitters

‘Passive’ HDMI splitters take a signal and divides it into multiple copies of itself, before sending it through multiple outputs. 

On the one hand, it’s important to consider that only half of the energy of the original signal will make it to each device. If the amount of energy is not sufficient to power both displays, the splitter will simply refuse to pass the signal through. This type of HDMI splitter would be useful for any place with a secure and strong cable signal, if not, the signal is simply duplicated and not amplified so the quality in unaffected.

On the other hand, ‘Active’ HDMI splitters are powered, which means that they have their own source of energy. There’s a limit to how far an electrical signal can travel before it starts to degrade (around 50 feet). With the use of active HDMI splitters, the signal is amplified and can be pushed further. This would be suitable for bars/pubs where multiple TV’s are needed to be in operation.

Final Considerations:

People who are still contemplating whether to buy a HDMI splitter may be asking if these nifty devices reduce the quality of the signal transmitted. As mentioned previously, HDMI Splitters do not automatically reduce quality because they are simplifying copying a digital signal. If the quality is poor while you are using a HDMI splitter it already means that your TV signal quality is low anyway. However, what is important to note is that when using unnecessarily long cable lengths to transmit the source, the signal quality gets degraded due to the resistance in the cable. For this reason it could be an idea to purchase a smaller HDMI cable if at all possible. We hope that we have answered the question ‘what is a hdmi splitter cable’ and provided you with sufficient  information to consider purchasing one here at Critical Power Supplies.
