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 AVR-S650H were rated 6 out of 10 against the 7 for the RX-V6A.
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 AVR-S650H works with the 4K/60Hz video, and the RX-V6A 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 Yamaha RX-V6A.
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 Yamaha RX-V6A.

Denon AVR-S650H got 5 points for the multichannel surround sound and Yamaha RX-V6A got 6.
Dolby Atmos' particularity is that this is the object-oriented sound format, that is, each audio signal object is independently sounded and connected to its spatial position. Yamaha RX-V6A can create 3D sound due to the Dolby Atmos support.
DTS:X is an algorithm used by the processor to create sound scenes, where sounds connected directly to objects rather than channels, and to determine the optimum sound output distribution in space. Surround sound with DTS:X is available on the RX-V6A.
