Xbox Series X makes extensive use of HDMI 2.1 features. Arcana 2 is therefore the correct choice for maximum video quality.
With this game console, resolution, HDR, refresh rate and low latency matter as much as audio. Arcana 2 is required when 4K120 and VRR must be preserved through the HDMI chain.
Arcana extracts audio from the HDMI signal before a TV or projector can restrict it. A compatible soundbar or receiver can therefore receive the best available soundtrack while the video signal continues to the display.
Arcana limits Xbox to HDMI 2.0 performance. Arcana 2 preserves 4K120 and VRR and can output full-quality audio separately.
Cable order: Xbox Series X → Arcana HDMI IN → HDMI OUT to TV/projector + eARC to soundbar
Use this route when 4K60 is sufficient and you need one video output.
Cable order: Xbox Series X → Arcana 2 HDMI IN → TX0 to TV/projector + eARC to soundbar
Use TX1/HDMI audio when a second display or HDMI receiver is required.
Arcana limits Xbox to HDMI 2.0 performance. Arcana 2 preserves 4K120 and VRR and can output full-quality audio separately.
Only use EDID, scaling or lip-sync corrections afterwards when the standard route demonstrably does not work.
The settings above are the starting point. These are the things that most often go wrong on this specific device.
Under TV & display options, the 4K TV details page lists every format the console believes the chain supports: 4K60, 4K120, VRR, ALLM, Dolby Vision, and the audio formats. Compare that against what you expect. A capability missing here is missing at the EDID level, which points at the display, the Arcana model or the cable — not at a game setting.
The Xbox will not offer Dolby Atmos for home theater as a bitstream option until the free Dolby Access app has been installed and used to enable it. This catches almost everyone. After that, set the audio output to bitstream with Dolby Atmos for home theater.
They live next to each other and it is easy to enable one and not the other, which produces a chain that looks correct but never shows HDR. Check both.
Still not right? Work through the troubleshooting pages — no Atmos, eARC falling back, lip sync and a black screen at 4K120 are covered there step by step.
