The most common questions about HDMI

Do you have a question or a problem about HDMI and can't find a solution from us? Then just ask us and we will help you with your HDMI problem.

What is HDMI and what can it do?

HDMI is an interface for the loss-free transmission of picture and sound in entertainment technology. In short, you can use an HDMI cable to connect your Bluray player or TV receiver to your television, for example. The picture and sound can then be transmitted to your television via the HDMI cable.

The transmission via the HDMI cable is digital and of very high quality. Numerous sound tracks (e.g. for 5.1 surround sound) and ultra high-resolution images (Ultra HD or 4k, 3D videos) can be transmitted at the same time. But HDMI can do a lot more:

Remote controls (CEC)

The connected devices can communicate via the HDMI cable using the CEC standard. This allows, for example, to control your Bluray player connected to the television with the remote control of your television. So you save yourself having to deal with several remote controls.

The audio return channel (ARC)

HDMI also has an audio return channel (ARC). This allows the sound to be exchanged in both directions via an HDMI cable. This makes cabling easier, especially when using a music system connected to the television, because you save an HDMI cable.

If you want to find out more about the audio return channel and the advantages of HDMI-ARC, I recommend the following article: Connecting a receiver.

Network via HDMI

Finally, the Ethernet channel has to be mentioned. This allows the network connection or Internet access to be distributed to the connected devices via an HDMI cable. It is sufficient to integrate the television into the network via LAN or WLAN and it can then provide this access to all connected devices. Even if modern HDMI cables offer this option, this last functionality is unfortunately not very widespread in practice and only a few devices and manufacturers support this.

How do I find the right HDMI cable?

You just need an HDMI cable and can't find your way around all the abbreviations on the subject of HDMI and the inexhaustible selection of HDMI cables? We can help you with that.

First the warning: Stay away from excessively overpriced HDMI cables like those sold by some large electronics chains. There is absolutely no reason to spend $ 20 or more on a 3 meter HDMI cable.

First of all, it is important which devices are to be connected with the HDMI cable. So if you need an HDMI cable to connect your TV receiver to your television, for example, you first have to check whether both devices have an HDMI connection. So check out whether both devices have an HDMI socket. If you're having trouble identifying the ports, take a look at our help on HDMI jacks and HDMI plugs.

If you find that one of the devices does not have an HDMI socket, you will need a corresponding HDMI adapter. We have prepared a help on the subject of HDMI adapters.

If both devices have an HDMI socket or you have a corresponding HDMI adapter, only the HDMI cable is missing. Our recommendation is: Always buy the latest generation of HDMI cables. These are hardly more expensive than older HDMI cables, but offer you all the options and HDMI functions and also equip you for the future.

We have selected an HDMI cable that complies with the latest HDMI standard. So there is nothing that cannot be done with this HDMI cable. It supports all existing HDMI functionalities:

  • High definition (HD)
  • Ultra HD (4K)
  • 3D videos
  • Audio Return Channel (ARC)
  • Consumer Electronics Control (CEC)
  • Ethernet channel
  • Multiple audio channels for surround sound

The HDMI cable is available in all common lengths and at a fair price.

Briefly explained: HDMI socket and HDMI plug

With HDMI, there is both an HDMI socket and an HDMI plug. The HDMI socket is usually built into devices such as televisions, Bluray players or TV receivers. The HDMI connector, on the other hand, is found on HDMI cables. A normal HDMI cable has an HDMI connector at both ends. As the name suggests, an HDMI plug is plugged into an HDMI socket.

The following picture shows two HDMI cables and an HDMI coupling that connects the two HDMI cables. The HDMI coupling has two HDMI sockets, the HDMI cables each have an HDMI plug.

HDMI connection: HDMI, Mini-HDMI and Micro-HDMI

The HDMI connection: With HDMI, there are different sizes of HDMI plugs and HDMI sockets. Depending on the space available and some other requirements, a different HDMI type or HDMI connection is used. There are a total of 4 different HDMI types in different sizes:

  1. The "normal" HDMI type is type A. It is used in entertainment electronics on televisions, Blu-ray players, TV receivers and many other devices. The HDMI type A is the largest and therefore the most robust type.
  2. Mini HDMI (HDMI Type C) is slightly smaller and is often used on devices with little space for connections. For example, it is often used in flat notebooks or ultrabooks and tablets.
  3. Micro HDMI (HDMI Type D) is the smallest HDMI type. Due to its very small design, it is used on devices with very little space. For example, HDMI sockets of the mini-HDMI type are used on smartphones.
  4. There is also the HDMI type E, which was developed for use in vehicles. It is therefore of little importance for consumer electronics.

Basically, the type A HDMI connection is the right choice for cabling your home entertainment center (e.g. television, Bluray player, TV receiver, audio amplifier, game console).
