HD Fury - 8K Arcana 2 VRR 40Gbps

HD Fury 8K Arcana 2 VRR 40Gbps is a unique HDMI adapter and splitter that revolutionizes how you handle video and audio signals in your home theater system. As the world's first 40Gbps VRR splitter, passthrough, upscaler, or downscaler up to 120Hz, it extracts full audio from any HDMI source and delivers it to any audio system in the best possible formats. This device is designed to solve compatibility issues between HDMI sources, displays, and audio systems, including support for eARC/ARC and HDMI audio extraction. It supports all existing video and audio signals, such as VRR, Dolby Vision (DV), Low Latency Dolby Vision (LLDV), HLG, HDR10+, DTS:X, Dolby Atmos, and much more. Whether you're a home theater enthusiast, gamer, or professional installer, 8K Arcana 2 always guarantees the best video quality for your display and the best audio for your audio system.

• Signal downscaling and upscaling: Handle all FRL or TMDS signals with downscaling such as 8K to 4K, 4K to 2K, or 8K to 2K up to 120Hz. Upscaling includes 2K to 4K, 4K to 8K, and 2K to 8K up to 120Hz (no upscaling for VRR, 1080i, 720p, or 480i/p).
• VRR and HDMI 2.1 support: Unlock true FRL/VRR on models such as Samsung Q90/QN900/QN95. Pass through all FRL/VRR signals and downscale the secondary output for Philips Hue Sync or similar.
• Highest resolutions and bandwidth: Up to 8K60 4:4:4/RGB 12-bit via DSC at 96Gbps, with full HDMI 2.1 passthrough up to FRL5: 40Gbps/1200MHz.
• Full audio extraction: Extract full audio up to Dolby Atmos/TrueHD from any HDMI source (including VRR signals) to any HDMI, ARC, or eARC audio system, such as SONOS Arc & Beam 2.
• Compatibility and solutions: Play Xbox One X games in 4K120 Dolby Vision on LG C9, BX, or Sony HDMI 2.1 TVs. Fix lip-sync issues with SONOS Arc/Beam 2 and external HDMI sources connected to an eARC TV. Enable DTS audio from the source to the audio system even if your TV does not support it.
• CEC control: Full CEC control from TV to source, volume control from source to eARC/HDMI audio system, and from TV to ARC/eARC system. Works with the TV remote or source remote.
• ARC/eARC management: Extract ARC/eARC from a TV input to any ARC or eARC audio system.
• Support for gaming and variable refresh rates: Handles 1080p120, 1440p120, 4K120, and all VRR signals from Xbox Series X, PS5, GPUs, and more.
• Dolby Vision conversion: Enable playback of DV content from LLDV-capable sources on any HDR10 display for improved picture quality.
• HDCP conversion: Convert HDCP 2.3 to 1.4.
• Signal modification: Change chroma, color space, and color depth as needed. Increase or decrease HDR metadata nit values in real time during HDR playback.
• Display and control: Live signal information on the OSD (On Screen Display) and OLED display. Navigate menus with the rotary switch. USB Type-C for power, USB Type-A for updates via USB drive, and RS232 for integration (not required for ordinary users).

 

How does it work?

8K Arcana 2 VRR is a smart converter for interoperability between HDMI sources (such as FUHD sources, Blu-ray players, UHD Blu-ray, media players, satellite receivers, game consoles, PCs, etc.) and displays or audio systems. In terms of hardware, it has 1 HDMI input, 2 HDMI outputs with scaling options, 1 eARC output, USB-A for updates, USB-C for power, RS232, an OLED display, and a rotary switch for menu navigation. The input handles 4K and 8K VRR/HDR/HLG/DV/LLDV/HDR10+ up to FRL5/40Gbps/1200MHz for video, and all audio formats available today. The HDMI TX0 and HDMI COPY outputs support FRL5/VRR/40Gbps/1200MHz, upscaling/downscaling, and all audio formats.

The device runs in standard mode as a splitter/passthrough/upscaler or downscaler to optimize your system. The unique HDMI COPY output is versatile and can be configured to:

• a) Split 2 signals up to FRL5 to 2 displays.
• b) Pass through a signal up to FRL5, downscale the other to TMDS for 4K FRL to 2K TMDS.
• c) Pass through a signal up to FRL5, retain 4K and adjust chroma/color depth for 4K FRL to 4K TMDS.
• d) Pass through a signal up to FRL5, extract full audio via a generated stream to feed a 1080p AVR.

On the software side, EDID handles the best possible mix of TV video and audio capabilities (e.g., SONOS Arc). It performs HDCP conversion, upscaling/downscaling, signal operations such as chroma/color depth/color space, HDR metadata handling, VRR, and audio extraction. It also allows DV playback from LLDV sources to HDR10 displays and real-time HDR nit adjustment. All signal information is clearly displayed via OLED or OSD.

This device is ideal for content creators, calibrators, streamers, digital entertainment centers, FUHD TVs, UHDTV stores, data centers, schools, conference rooms, or home theaters.

Getting started - Installation

One source + eARC: Connect the HDMI output from your source to the 8K Arcana 2's HDMI input. Connect Arcana's HDMI output to any projector, monitor, or display. Connect the eARC output to a SONOS Arc or similar. If your display has an ARC/eARC input, you can get TV audio from it. This provides full audio up to Atmos/TrueHD from the HDMI source, the eARC signal for TV audio, and CEC volume control from the source or TV.

Multiple sources + eARC: Connect all sources to an HDMI switch (or receiver) and the switch output to Arcana's HDMI input. Continue as above. Use the HDMI COPY output to split/mirror the signal, downscale VRR for Hue Sync, a capture card, lower-spec displays, or as an audio output for older AVRs with a 1080p stream and full audio.

Use HDMI cables that support 40Gbps/1200MHz from the source to Arcana and from Arcana to the display (recommended: HD Fury, Cable Matters, Zeskit, Kabeldirekt; min. 2m, max. 4m copper; longer with fiber). For eARC to SONOS, only ARC/eARC support is needed (such as the included SONOS cable).

Frequently asked questions (FAQ)

• What problem does it solve? eARC is an HDMI 2.1 feature for full audio up to Atmos/TrueHD, but many TVs, projectors, and monitors lack it. 8K Arcana 2 acts as an eARC TV, takes HDMI signals, and delivers full audio via the eARC output.
• Can it upgrade my ARC TV to eARC? No, but it bypasses the limitation by extracting full audio from external HDMI sources.
• Does it solve lip sync problems? Yes, unlike TVs that downmix or re-encode audio with a delay, Arcana handles EDID optimally to avoid lip sync issues with SONOS Arc.
• Volume control? CEC allows volume control from the TV or source remote to the eARC/HDMI audio system. SONOS Arc can also learn IR signals from any remote.
