Do HDMI Switches/Splitters Cause Input Lag?

HDMI switches and splitters help boost the home theater system by allowing you to manage multiple devices with one HDMI input and divide one video source into multiple locations, respectively. 

An HDMI switch helps route multiple HDMI source channels into one, enabling you to expand the number of inputs your device can accept. On the other hand, an HDMI splitter is a handy accessory that can add to your convenience and help you save some money. It allows you to get the same content on all your screens.

Sometimes, people notice that their systems start lagging after using these accessories.   

In such circumstances, they can’t help but wonder, “Do HDMI switches/splitters cause input lag?”

We’ve prepared this guide to answer this question.

But first…

What is Input Lag?

Input lag refers to the delay you experience after clicking a button on your controller until the results appear on the screen. The lower it is, the faster your device will respond. The amount of delay may vary from one device to another.

Needless to say, input lag can make movie time or gaming experience a nightmare.

Do HDMI Switches Cause Input Lag?

You don’t have to worry about input lag with HDMI switches as long as you get a good-quality, active one. Active switches run through an AC adapter on an external power supply. With them, there is generally no noticeable lag.  

Do HDMI Splitters Cause Input Lag?

As opposed to HDMI switches, splitters do add some input lag. However, it’s no more than a few milliseconds. The delay is so short that you probably won’t even notice it.

Nonetheless, we recommend using a powered HDMI splitter  if you want to enjoy fast splitting.   

Powered HDMI splitters ensure that the digital signals are copied in high quality. Additionally, they boost the signals to reduce any chances of interference if you’re using longer cables.    

How Do HDMI Splitters Deal With Input Lag?

If you’re concerned about the potential input lag caused by HDMI splitting, this section will answer all your questions.

You should worry about input lag only if your system is non-powered. If you have a splitter that connects to a power source, you can rest assured that it is equipped with the appropriate internal equipment to duplicate the HDMI signal without disruptions or delays caused by extra processing.

That being said, since HDMI splitters are a new link in the video signal chain, you can expect some input lag. However, with a powered unit, this delay will be no more than two milliseconds. That’s just a couple of frames of 60 Hz signal.

If you’re a hard-core gamer, you should find an HDMI splitter that promises to provide the refresh rate you’re looking for. If you want to split to 120Hz screens, the capability of your splitter should match that of other components.     

The Bottom Line

Whether you want to open up space for plugging in your gaming console or run a signal to multiple devices so that you don’t have to swap the HDMI cables repeatedly, you should get an HDMI switch or splitter. 

Now that we have answered the burning question, “Do HDMI switches/splitters cause input lag?”, you can put your mind at ease.

We understand how frustrating it is to deal with delays when playing an intense game or watching an action movie. HDMI splitters and switches can quickly become a headache if your system starts lagging because of them.

Thankfully, HDMI switches don’t cause any delay in reaction times, allowing you to enjoy a seamless home theatre experience. On the other hand, HDMI splitters are reported to cause a minor lag. However, it’ll be too small for you to notice.       

Using powered products can help eliminate the risk of input lag with HDMI splitters and switches.
