AV receivers with HDMI, such as the Pioneer*, offer basic requirements for compatibility with all common external devices. Therefore, HDMI is a central technical feature of the receiver.
What started out as a trend has long since established itself as a common standard. For this reason, not every older AV receiver has an HDMI port. In the meantime, however, HDMI connections have become a firmly established part of the HiFi sector and it is impossible to imagine life without them. Regardless of the fact that the importance of HDMI for AV receivers is so central, there are still great uncertainties in the typical designations of the standard. The interface transmits picture and sound simultaneously.

This fact makes wiring and handling in the home theater room immensely easier. The HDMI cable can be considered the successor of the Scart cable. The immensely helpful technical standard is constantly evolving.
Finally, the resolution increases and moreover, new color standards establish themselves just as the sound generally improves. The development of HDMI has now reached 2.1. Therefore, many AV receivers carry the designation AV receiver HDMI 2.1.

AV receivers with HDMI

What does HDMI mean?

The well-known abbreviation HDMI stands for High Definition Multimedia Interface. In this sense, this interface for image and sound transmission is characterized by high quality. After all, the intention for the development of HDMI was to create a general standard in the entertainment industry.
Therefore, many renowned manufacturers were involved in its development in order to find a common consensus for the interface. For example, the connectors of HDMI cables are characterized by an extremely flat design consisting of two rows of contacts.

Transmission classes of HDMI

There are four different categories of HDMI.

❶ HDMI standard

HMDI standard allows data transmission rates of 1.782 Gbit/s. In addition, the maximum image resolution here is 1080p.

❷ HDMI High Speed

The HDMI High Speed enables transfer rates of up to 8.16 Gbit/s. Furthermore, the maximum resolution of the image is 1440p.

❸ HDMI Premium High Speed

The speed of HDMI Premium High Speed is more than double that of HDMI High Speed. Thus, its transmission rate is 18 Gbit/s. Accordingly, the image resolution is at least 2160p, if not higher.

❹ HDMI Ultra High Speed

This transmission class achieves rates of 48 Gbit/s. In addition, the HDMI Ultra High Speed allows the image to have a resolution of 8 K, which is equivalent to 8192p.

Importance of HDMI for an AV receiver

As is well known, the central task of an AV receiver is to receive different audio and video signals. Consequently, the highest possible quality of the output of these signals is possible through an HDMI interface.

This overview implies the importance of HDMI in general and the need for an HDMI interface in particular. For this reason, thanks to HDMI, it is possible how devices listed in the overview can be connected at an AV receiver.
Unlike a USB cable, the connectors of an HDMI cable are identical on both sides. All models in the comparative overview of 10 good AV receivers have HDMI.

AV receiver HDMI 2.1

The rapid spread of HDMI can be seen in the fact that every component within a home theater now has its own HDMI interface. This interface is permanently installed within the hardware.
In addition, it can be changed afterwards by suitable updates. When buying an AV receiver HDMI, it tends to be better to pay attention to the latest HDMI standard, so that the multi-channel amplifier is most likely compatible with the other components of the home theater.

Without any ifs and buts, the projector for projecting movies onto the screen is the be-all and end-all of a home theater. When buying the right projector, you should pay attention to the support of a 4 K standard.
In the case of the right projector for an AV receiver, this requires an HDMI 2.0 standard. A higher standard like HDMI 2.1 makes no sense because the projector is not capable of outputting this standard at all.
The situation is the same for other feed players in the home theater, which cannot implement a transmission standard of 2.1. The only component in the home theater that is exempt from this rule is the television.
In the meantime, devices with a picture standard of 8 K HDR exist on the market. For this reason, these TVs have the HDMI 2.1 transmission standard. The bottom line is that this ensures that the HDR TV can receive its high-resolution images.

An AV receiver with HDMI* bundles the picture and sound signals in itself. The required transmission standard of the AV receiver is specifically based on the highest resolution of a component in the home theater.
For this reason, a newly purchased, high-resolution TV can only develop its effect if this is in harmony with the AV receiver. In practice, it looks like an AV receiver HDMI 2.1 can rarely unfold its full potential.
Thus, many feed players do not have such a transmission standard. In other words, an AV receiver HDMI 2.0 is more than sufficient for most applications. And this circumstance will not change much in the foreseeable future.

AV receiver HDMI connect correctly

A more important point than using the highest transmission standard is the use of suitable cables. In principle, these represent the Achilles heel for being able to transmit data in sufficient quantity.
In particular, the distance between the individual components can be problematic. Data loss can occur here, which can stand in the way of smooth movie watching.
