Xbox One S/X and Series X|S + Vertex

This guide shows which Xbox video settings to switch on for 4K HDR10 and Dolby Vision streaming through the original Vertex, and which HDMI 2.1 features to switch off.

Xbox One S (2016), Xbox One X (2017), Xbox Series X and Series S (2020). The original Xbox One (2013) has no 4K or HDR output and is not covered. Dolby Vision here means video in streaming apps; Dolby Vision gaming on Series X|S is aimed at 4K 120Hz and is not part of this guide.

DOLBY VISION WITH THIS SETUP

Xbox plays Dolby Vision video in streaming apps; HDfury lists Xbox One X/S as an LLDV source, so an Xbox One can feed an HDR10 projector through the Vertex.

Native Dolby Vision: PARTLYXbox One S/X (since the 1810 update in 2018) and Series X|S have 'Allow Dolby Vision'. Press reported in 2018 that Xbox One Dolby Vision only worked with some TVs, which it linked to the Xbox using low-latency (player-led) Dolby Vision.
LLDV via the Vertex: PARTLYXbox One X/S: yes, for Dolby Vision content only (HDfury's LLDV source list). Series X|S is not on that list: check the signal at the Vertex. Xbox does not convert HDR10 or SDR video to LLDV.
HDR10: YESXbox One S, One X and Series X|S output HDR10 with 'Allow HDR10' ticked.

Before you start

Xbox menu names below come from Xbox press material and support page titles. Current menu wording could not be read from support.xbox.com (the page needs JavaScript); check it on your console.
The original Vertex handles up to 18Gbps: 4K 60Hz is the limit. 4K 120Hz, VRR and ALLM do not pass.
Get 4K HDR10 working first, then allow Dolby Vision.
Restart the console after changing the EDID on the Vertex so it reads the new one.

THE VERTEX PART

Vertex settings for this setup

Dolby Vision TV: connect the TV to the Vertex BOTTOM output and follow part A — EDID "COPY BOT SINK" (or Automix with "DV Force Metadata"), No Scaling, InfoFrame tools off.
HDR10 projector or TV (LLDV): follow part B — upload an LLDV EDID into a free custom slot (CUSTOM 4–10) and select it for the Vertex input this player is connected to. Then make the display switch to HDR (part B2).
The Xbox connects to a Vertex input; a Dolby Vision TV goes on the Vertex BOTTOM output, an HDR10 projector gets the LLDV EDID route.
HDfury lists Xbox One X/S as an LLDV source for Dolby Vision content only.
Series X|S is not on HDfury's LLDV list: check what arrives on the Vertex OLED before tuning the projector.
Only 4K 60Hz and lower pass the original Vertex; Xbox 4K 120Hz modes do not.

VERTEX DOLBY VISION SETUP — ALL STEPS →

Switch these off

Refresh rate 120Hz (Series X|S)4K 120Hz needs HDMI 2.1 bandwidth the original Vertex does not have.
Allow variable refresh rate (Series X|S)VRR is an HDMI 2.1 feature that does not pass the original Vertex.
Allow auto low-latency mode (Series X|S)ALLM is an HDMI 2.1 feature that does not pass the original Vertex.

How you know it works

Settings → General → TV & display options → 4K TV details: shows whether 4K 60Hz, HDR10 and Dolby Vision are supported by what the Xbox sees (menu wording to confirm on your console).
Vertex OLED Info page, line INP: shows the incoming resolution, chroma, bit depth and HDR flag while a Dolby Vision title plays.

Problems and fixes

4K TV details says Dolby Vision is not supported.

The EDID from the Vertex does not report Dolby Vision. Fix the EDID on the Vertex, then restart the Xbox.

Dolby Vision works with one TV but not another.

Xbox uses low-latency (player-led) Dolby Vision. Displays that only accept TV-led Dolby Vision may reject it (FlatpanelsHD, 2018).

No picture after changing the refresh rate.

You probably chose 120Hz. Go back to 60Hz: the original Vertex cannot pass 4K 120Hz.

NOT CONFIRMED BY THE MANUFACTURER

The exact current Xbox menu wording (TV & display options, Video modes, 4K TV details). Official Xbox support pages could not be read without a browser; the 2018 Xbox Wire path is for the old Xbox One menu.
Whether Xbox Series X|S sends LLDV. HDfury's LLDV list names only Xbox One X/S.
The 'Dolby Vision for gaming' option on Series X|S and how it behaves at 4K 60Hz. It is not covered here; leave it off while setting up.
