Bluetooth connection is now one of the main communication protocols for the receiver's control or even music broadcasting.

DLNA is the perfect way to use your local cloud storage to stream movies and music directly to a TV. You can use the DLNA protocol only with Denon AVR-X4700H.

Streaming services

Now music streaming services are gaining more and more popularity. They allow users to listen to millions of songs by subscription.

Extensive connections

The presence of many connectors makes the receiver more versatile. But there are also narrowly targeted models, the number of connectors which are limited to a certain area of use. And when choosing their own receiver, users need to consider exactly your goals for using the receiver. For extensive connection, Onkyo TX-RZ840 got 8 points, but Denon AVR-X4700H received 10 points.

Onkyo TX-RZ840 is equipped with 7/2 HDMI inputs and outputs, and Denon AVR-X4700H has 8/3 HDMI inputs and outputs.

The HDCP encryption protocol is now mandatory for most media devices. This security technology encrypts digital signals from one product to another. HDCP content-encryption protocol is present on Onkyo TX-RZ840 in the HDCP 2.2 version, and Denon AVR-X4700H has the HDCP 2.3 version.

Video features

The AV receiver is the heart of the home theater. And in this case, support for all current video formats ensures the best user experience, so it is very important to consider this when choosing a device. Video features of the TX-RZ840 were rated 8 out of 10 against the 10 for the AVR-X4700H.

With the 4K pass-through feature, the AV receiver sends "native" 4K signals to a 4K TV from a video source without any processing. The TX-RZ840 works with the 4K/60Hz video, and the AVR-X4700H has the 4K/120Hz.

The AV receiver passes "native" 8K signals from a video source to 8K TV without any encoding, with the 8k pass-through features. The 8K path-through is available on Denon AVR-X4700H.

Most of the AV receivers have a video scaling function, it is the process of reformatting the video signal to a higher resolution without losing the quality of the image. Upscaling the video signal resolution is possible with Denon AVR-X4700H.

Additional features

In terms of evaluating additional features, the TX-RZ840 got 9 points, but the AVR-X4700H has 10.

Denon AVR-X4700H has the ECO mode.

Multi-room
