Denon AVR-S770H features 3 HDMI 2.1 inputs with 8K support and 3 inputs with 4K support. It has 1 output.
- 8K/60Hz and 4K/120Hz Passthrough: 3 out of 6 inputs pass up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 and the rest of the inputs pass up to 4K 50/60Hz 4:4:4 video signal.
- 8K Upscaling: Denon AVR-S770H can upscale from 1080p up to 8K 50/60Hz and 4K 50/60Hz 4:4:4 from HDMI sources.
- 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%.
- HDCP 2.3 Copy Protection: All inputs and outputs are HDCP 2.3 compliant which is a requirement for 4K/HDR copy-protected content transmission.
- 3D Ready: Denon AVR-S770H is able to pass 3D video through HDMI.
HDR (High Dynamic Range)
Denon AVR-S770H supports HDR (high dynamic range) video formats such as HDR10, HDR10+, Dolby Vision, Dynamic HDR and Hybrid Log-Gamma via HDMI ports. 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)
Audio Return Channel (ARC) feature 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-S770H supports Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.
