How Do Hdmi Splitters Work And Can They Reduce Cable Clutter

HDMI, or high definition multimedia interface, cables have been around for a while. Computers, game consoles, and a lot of other things use them. HDMI splitters are useful when you need to connect more than one device or screen.

How do HDMI splitters actually work? And what do they even do? Keep reading, because this article will tell you the answers to both of these questions.

How do HDMI splitters work?

A HDMI splitter is a small hub with one port for input and several ports for output. The only input port is used to connect the laptop. The HDMI splitter copies the signal and sends it to the monitors through the output ports.

So, how would you use one? So, let’s say a presenter wants to show the screen of their laptop on more than one screen during a presentation. To do this, they will need to plug their laptop into an HDMI splitter. A HDMI splitter does exactly what its name says: it splits the HDMI signal so that one signal can go to multiple displays.

There are two main kinds of HDMI splitters: passive and active. Read on to learn more about both of them.

Passive HDMI Splitters

Passive HDMI splitters take a signal and make multiple copies of it, which are then sent out of multiple outputs. This is the easiest way to send the signal to more than one display, and it also uses the least amount of power.

Still, there are some problems with passive HDMI splitters.

Each device will only get half of the energy of the original signal. If there isn’t enough power to run both displays, the splitter usually won’t let the signal through.

Active HDMI Splitters

Active HDMI splitters are powered, which means they have their own source of energy. So, they can add enough power to the original signal to make sure that all displays get a strong signal.

Active HDMI splitters can also help keep the signal from getting worse. An electrical signal can only travel so far before it starts to break down. About 50 feet is how far an HDMI signal can travel. With an active HDMI splitter, the signal is amplified, so it can be sent further.

Why are HDMI splitters a bad idea?

You now know the answer to the question, “How do HDMI splitters work?” Even though both versions have benefits, you also need to think about some other drawbacks. Here is a list of these.

HDCP

HDCP is something that people have to deal with when they use splitters. “High-bandwidth digital content protection” is what this stands for.

Intel made HDCP as a way to stop people from stealing digital content. It makes sure that the signal going through the cable is not something that is protected by a copyright. Even though it seems like a good idea, it can cause problems for people who use it.

“HDMI handshaking” is the name of the technology that HDCP is built on. This is the process by which the monitor and the source (such as a game console, laptop, etc.) are always talking to each other. If the information going through the cable is encrypted in some way, the devices will cut off the connection.

The problem is that most content is not streamed with the goal of stealing it. People like to watch movies and TV shows on bigger screens or on several screens at the same time in public places. If the devices find that the content is protected by intellectual property rights, the connection will be cut off.

Problems with the screen resolution

If the monitors are set to different resolutions, it can be hard to send a signal to more than one. A HDMI splitter does not change the signal for the monitor, so both monitors will get the same signal.

If the resolutions don’t vary too much, everything should be fine. But if you try to send a 4K signal to one 4K display and a 720p display at the same time, that could cause some problems.

It’s best to make sure that both monitors have the same resolution, or at least resolutions that are close to each other. On top of that, you should also make sure the monitors work with the signal you’re splitting.

HDMI Version Incompatibility

Like USB, HDMI has different version numbers that show how technology has changed over time. Because of this, it is important to make sure that the HDMI version used by the monitor, the splitter, and the source are all the same. If there are problems, the signal might not be able to get through.

As of mid-June 2021, HDMI version 2.1 is the most up-to-date version. If a monitor can only handle version 1.1, it won’t be able to show a picture from a source that sends version 2.1. On the other hand, HDMI can work with older devices. This means that a monitor that can handle HDMI version 2.1 can also show a picture from a source that only supports HDMI version 1.1.

Also, you should make sure that the cable you’re using is of good quality. People wonder if HDMI cables with gold plating are better. In reality, you should never judge a cable by how it looks. Instead, you should read the box. After you do this, you’ll be able to make a better choice.

How HDMI Splitters Can Help Reduce Clutter

The most obvious advantage of HDMI splitters is that they let you send one video feed to multiple monitors. Also, HDMI splitters keep things from getting too messy.

If the user didn’t have one, they would need more than one source. This means that each source would need its own cord to connect to each monitor separately, which would be a huge mess to keep track of. With an HDMI splitter, you only need one source. This cuts down on the number of cords you need.

So, can an HDMI signal be split? Short answer: yes. But you have to make sure everything works well together.

If you use more than one monitor every day, you should get an HDMI splitter. They are useful in most situations. As with any piece of technology, you need to know how to use them correctly to avoid problems.

You can find HDMI splitters in electronic stores all over the world, so it shouldn’t be hard to find the right one to make your life less cluttered.
