HDMI

What is HDMI?

HDMI stands for High Definition Multimedia Interface and is an interface for transmitting images and sound. This standard was developed in 2003. Similar to how you use USB cables to connect printers or external hard drives to your PC, an HDMI cable is used to connect a Blu-ray player or a game console to your TV. With the HDMI cable, images and sound can be transmitted in parallel to a TV, monitor, or projector. Each cable has identical connectors at both ends, so it doesn't matter which side is connected to the input or output. You can find the appropriate socket on all devices with an HDMI connection.

How do HDMI cables differ?

If you think that you can't go wrong when buying an HDMI cable because it's a uniform standard, you're unfortunately mistaken. Similar to what you already know from USB cables, there are different sizes, lengths, and transmission speeds available. Therefore, before buying a multimedia cable, you should check which HDMI type your hardware needs. To give you some help, we'll show you the different features:

Different connector sizes

With shrinking device sizes and less space on the hardware housing, different connector sizes have now been established:

• Standard HDMI: This connector size is also called Type A. The standard is used for home entertainment electronics such as TVs, PC monitors, DVD players, or game consoles. The HDMI Type A is the largest type and therefore the most robust connector.
• Mini HDMI: This connector size is also called Type C. This connector is slightly smaller than the standard and is used for devices with slim housings and little space for connections. You can usually find it in newer notebooks, tablets, and some digital cameras.
• Micro HDMI: This connector size is also called Micro HDMI Type D. Due to the progressive miniaturization of hardware, this size was additionally created and is used for devices that are extremely flat, as is known from smartphones.

All three connectors have the same 19 pins, but some may have a different pin assignment. However, they all support the resolutions and functions of HDMI 1.4 and higher.

What is HDMI?

HDMI stands for High Definition Multimedia Interface and is an interface for transmitting audio and video. This standard was developed in 2003. Similarly to how you use USB cables to connect printers or external hard drives to your computer, an HDMI cable is used to connect a Blu-ray player or game console to your TV. With the HDMI cable, both audio and video can be transmitted to a TV, monitor, or projector simultaneously. Each cable has identical connectors at both ends, so it doesn't matter which side is connected to the input or output. You will find the appropriate port on all devices with an HDMI port.

If you think that you can't go wrong when buying an HDMI cable because it's a uniform standard, you'll be disappointed. Similar to what you already know about USB cables, there are different sizes, lengths, and transmission speeds for HDMI cables. Therefore, before buying the multimedia cable, you should check which HDMI type is required for your hardware. To help you out, we will show you the different characteristics:

Different connector sizes

With shrinking device sizes and less and less space on the hardware case, different connector sizes have now become established:

• Standard HDMI: This connector size is also known as Type A. The standard is used in home entertainment electronics such as televisions, PC monitors, DVD players, or game consoles. The HDMI Type A is the largest and most robust type of connector.
• Mini HDMI: This connector size is also known as Type C. This connector is slightly smaller than the standard and is used in devices with slim housings and little space for connections. You will find it mostly in newer notebooks, tablets, and some digital cameras.
• Micro HDMI: This connector size is also known as Micro-HDMI Type D. Due to the advancing miniaturization of hardware, this size was created in addition and is used in devices that are extremely flat, as you know it from smartphones.

All three connectors have the same 19 pins, some may have a different pin assignment. However, they all support the resolutions and functions of HDMI 1.4 and higher.

So, if you want to connect two devices via HDMI, follow these steps: Find the corresponding HDMI port on both devices. The ports may look different on both devices if they are different types (standard, mini, micro). You will find the appropriate cable for each combination of sizes.

Different transmission rates

Increasing amounts of data, high frame rates, and growing screen resolutions have made higher transmission rates necessary over time.

Therefore, various HDMI versions are constantly being developed, which differ in their transmission speed, bandwidth, and supported functions. The most common HDMI versions are:

HDMI versions at a glance

• HDMI to VGA adapter: This adapter is used to convert an HDMI signal to a VGA signal. It is often used to connect older monitors or projectors to newer HDMI-enabled devices like laptops or game consoles.
• HDMI to DVI adapter: This adapter is used to convert an HDMI signal to a DVI signal. It is often used to connect older computer monitors to newer HDMI-enabled devices.
• HDMI to DisplayPort adapter: This adapter is used to convert an HDMI signal to a DisplayPort signal. It is often used to transfer an HDMI signal from a laptop or desktop computer to a monitor that only has a DisplayPort connection.
• HDMI splitter: An HDMI splitter is used to transmit an HDMI signal to multiple devices at the same time. It is often used to transmit a signal from a DVD player or game console to multiple televisions or monitors.

Supported formats of an HDMI adapter:

The technical differences between the various HDMI adapters mainly lie in the way they convert or transmit the signal. For example, some adapters only support certain HDMI versions or have limited bandwidth that affects the maximum transmission rate. It is therefore important to choose the right adapter for the specific device and application.

Transmission values of HDMI adapters

The transmission values of HDMI adapters can vary, but typically they offer the following performance features:

• Support for video resolutions of up to 4K Ultra HD (3840 x 2160 pixels) at 60 Hz
• Transmission of 8-channel audio
• Support for HDR (High Dynamic Range) and 3D content

Use of HDMI adapters

HDMI adapters are often used to connect devices such as laptops, game consoles, DVD players, and smartphones to a television, monitor, or projector. They are a practical solution for connecting various devices and enjoying high-quality audio and video content.

The use of an HDMI adapter can affect image quality if the adapter is unable to process the signal with sufficient bandwidth or transmission rate. It is therefore important to choose a high-quality adapter that is suitable for the desired application.

Different plug sizes

With shrinking device sizes and less and less space on the housing of the hardware, different plug sizes have now established themselves:

• Standard HDMI: This plug size is also known as type A. The standard is used in home entertainment electronics, such as televisions, PC monitors, DVD players, or game consoles. The HDMI type A is the largest type and therefore the most robust connector.
• Mini HDMI: This plug size is also known as type C. This connector is slightly smaller than the standard and is used in devices with slim housings and little space for connections. You will mostly find it in newer notebooks, tablets, and some digital cameras.

All three plugs have the same 19 pins, but some can have a different pin assignment. However, they all support the resolutions and functions of HDMI 1.4 and higher.
