Denon AVR-X4400H comes with 8 HDMI inputs. It has 3 outputs - 2 for MAIN and 1 for ZONE2.
Yamaha RX-V4A comes with 4 HDMI 2.1 inputs with 8K support. It has 1 output.
- 4K/60Hz Passthrough on Denon AVR-X4400H: All inputs pass up to 4K 50/60Hz 4:4:4 video signal.
8K/60Hz and 4K/120Hz Passthrough on Yamaha RX-V4A: All inputs pass up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 video signal. - 4K Upscaling: Both receivers can upscale up to 4K 50/60Hz 4:4:4 from HDMI sources. Denon AVR-X4400H can also upscale from analog sources.
- Analog To HDMI Upconversion: Denon AVR-X4400H supports analog to HDMI Upconversion, so you can input your analog video sources and output them digitally via HDMI. This means that you will need only one HDMI cable to connect to your TV.
- BT.2020 Color Space: BT.2020 or Rec. 2020 is a color standard which delivers a wider color gamut compared to Rec. 709. It covers approximately 75% of the total visual spectrum while the Rec. 709 covers only 35% (available on both models).
- HDCP Copy Protection: Denon AVR-X4400H is HDCP 2.2 and Yamaha RX-V4A is HDCP 2.3 compliant which is a requirement for 4K/HDR copy-protected content transmission.
- Quick Media Switching (QMS): With HDMI 2.1a, Quick Media Switching for movies and video uses the HDMI VRR mechanism to eliminate the blackout period when an HDMI Source device switches its video mode. As long as the resolution remains the same and only the frame rate changes, QMS will instantly switch between frame rates. QMS eliminates A/V blackouts by using VRR technology to change frame rates, allowing instant changes from 24Hz to 60Hz frame rate, and anywhere in-between. The viewer never sees blank screens and gets a seamless experience (available on Yamaha RX-V4A only).
- 3D Ready: Both receivers are able to pass 3D video through HDMI.
HDR (High Dynamic Range)
Denon AVR-X4400H supports HDR10, Dolby Vision and Hybrid Log-Gamma.
Yamaha RX-V4A supports HDR10, HDR10+, Dolby Vision and Hybrid Log-Gamma. High dynamic range video has greater dynamic range than standard dynamic range (SDR) video with brighter whites and deeper blacks. The result is greater contrast and more details in dark and bright areas, better color and depth.
Enhanced Audio Return Channel (eARC)
Denon AVR-X4400H and Yamaha RX-V4A support Audio Return Channel (ARC) which allows the compatible TV to send audio signal to the a/v receiver through the same HDMI cable which is used to send audio and video signals to the TV. So one HDMI cable is used to transfer audio signal in both directions. New Enhanced ARC will support uncompressed audio formats such as Dolby Atmos, DTS:X, Dolby TrueHD and DTS HD Master Audio whereas the previous ARC could support only Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.
Gaming Features
Denon AVR-X4400H supports Auto Low Latency Mode (ALLM) Yamaha RX-V4A supports Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.
