What Is an HDMI Distribution Amplifier or HDMI Distribution Box?

As an example, you can use an HDMI distribution amplifier to stream to multiple TVs using a single source

To get an idea of how this works, it’s similar to how you would go about connecting multiple speakers to amplifiers. Since copying the signal weakens it, the HDMI distribution box not only duplicates the input signal but increases the signal strength as well.

Things To Consider Before Purchasing an HDMI Distribution Amplifier

 There are certain things to consider before purchasing an HDMI distribution amplifier to ensure you get the best fit for your requirements.

  • The Number of Monitors: The first thing to consider when purchasing an HDMI distribution amplifier is the number of monitors, which will display the signal. Once you have determined this, you will be sure whether to get a 1×2, 1×4, or 1×8 amplifier. This will help you avoid getting an amplifier that cannot serve your need sufficiently.
  • Your Device: Another thing to consider is the device that you are using the distribution amplifier for. Your device must have an HDMI interface to be able to work with an HDMI distribution amplifier. You should, therefore, confirm that your device has an HDMI interface before purchasing an HDMI distribution amplifier.

Some amplifiers are long enough to cover a good range, while some are not so lengthy. It is essential to keep in mind, the distance between your monitors when purchasing an HDMI distribution amplifier.
  • Two HDMI Devices: Many people consider an HDMI distribution amplifier when using two HDMI devices on one TV or LCD. However, using two HDMI devices requires an HDMI switch rather than an HDMI distribution amplifier.


Benefits Of HDMI Distribution Amplifiers

  • Cost Saving: HDMI distribution amplifiers save cost, as you can display content from one source on a good number of TVs (as many as eight). This way, you save the money needed for buying another television, blue ray disc player, cable, or video gaming console.
  • It Saves Space: A HDMI distribution amplifier helps you save space in your living room or bedroom, as the case may be.

Do All HDMI Splitters Need Power?

Lower-quality HDMI Splitters do not require an external power source and so cannot transmit a clear signal beyond 15 feet. Powered HDMI splitters however are able to transmit and boost quality digital signals much farther than the non-powered variants.

What Is The Difference Between HDMI Splitter And HDMI Switcher?

An HDMI splitter accepts a single video and audio input source, duplicates, and distributes it to several output screens. An HDMI switch, on the other hand, accepts several video and audio input sources and sends them to a single device or screen via the cable output. The two devices are essentially opposite in function.

Does Using An HDMI Splitter Reduce Quality?

Because they are replicating a digital signal, HDMI distribution amplifiers do not automatically lower quality. Using lesser-quality hardware or a non-powered HDMI Splitter, on the other hand, is less certain. Due to the length of the HDMI connection, splitters used with excessively lengthy HDMI cables may have signal quality concerns.

Also, splitters automatically default to the lowest resolution of the connected output devices, which means that whichever of the displays is of a lesser quality resolution is the one the splitter will default to.

Wrap Up:

Getting an HDMI distribution amplifier or HDMI distribution box is a no-brainer at this point, as most devices now come with an HDMI interface. Simply follow the steps to consider before choosing one, and you are sure to enjoy your amplifier hitch-free.
