JVC / D-ILA PROJECTOR (2017)

JVC X5900 / X7900 / X9900 + Vertex

The 2017 JVC projectors switch to Picture Mode HDR only when they detect an HDR signal. LLDV from the Vertex has no HDR flag, so this guide shows how to set the PQ gamma yourself or let the Vertex trigger it.

JVC DLA-X5900 / DLA-X7900 / DLA-X9900 (EU), US DLA-RS440 / RS540 / RS640, Asia DLA-X590R / X790R / X990R. 4K e-shift4. Not covered: the 2016 X5000/X7000/X9000 (Gamma D).

DOLBY VISION WITH THIS SETUP

No native Dolby Vision; LLDV from the Vertex works with Gamma HDR(ST.2084) and BT.2020 chosen by hand, or with the Vertex HDR InfoFrame.

Native Dolby Vision: NOThe projector does not accept a Dolby Vision signal. It supports HDR10 and HLG.
LLDV via the Vertex: YESPicture Mode HDR is selected automatically only if an HDR signal is detected. LLDV has none, so select HDR or a User mode and Gamma HDR(ST.2084) yourself, or let the Vertex add an HDR InfoFrame.
HDR10: YESJVC specifies two HDMI inputs (18Gbps, HDCP 2.2) with 4K60p 4:4:4, 4K60p 4:2:2 36-bit and 4K24p 4:4:4 36-bit.

Before you start

Gamma HDR(ST.2084) can be selected in the Cinema, Animation, Natural, HDR and User modes.
There is no menu item called 'HDR Auto Picture'. The mode is simply Picture Mode 'HDR'.
You need a player that outputs LLDV and an LLDV EDID on the Vertex. The Vertex passes up to 18Gbps (4K60 4:4:4 8-bit, 4K60 4:2:2 12-bit, 4K120 4:2:0 8-bit). HDMI 2.1 modes (4K120 10-bit HDR, VRR, ALLM) do not pass.

1. Basic picture settings

Get HDR10 working through the Vertex first. Then add LLDV.

2. LLDV: select the HDR mode by hand

Back to SDRPicture Adjust → Picture ModeYour normal SDR modeThe HDR or User mode keeps the PQ gamma; SDR in that mode looks wrong.

3. LLDV alternatives: Vertex HDR InfoFrame or JVC custom gamma

Option B: let the Vertex trigger HDRPicture Adjust → Picture ModeCheck that HDR is selected once LLDV playsWith the Vertex 'Enable Custom HDR' InfoFrame the JVC detects an HDR signal and selects the HDR mode (Vertex steps: see the central Vertex page).
Option C: JVC custom gammaPicture Adjust → Picture Mode → User mode, then Picture Adjust → GammaYour own custom gamma curve for LLDVHDfury says the original Vertex works for LLDV with a JVC custom gamma curve; the Vertex 'Disable HDR' then removes all HDR metadata so your curve is used.

THE VERTEX PART

Vertex settings for this setup

LLDV: either force HDR on the display (see the steps above) or let the Vertex send an HDR10 InfoFrame with Enable Custom HDR (part B2). Use one of the two, and undo it for SDR.
Connect the JVC to a Vertex output (often TOP when a Dolby Vision TV uses BOTTOM); give the player's Vertex input an LLDV EDID.
HDR trigger is optional: Picture Mode HDR or User with Gamma HDR(ST.2084) works without it.
For the JVC custom-gamma route HDfury uses the Vertex 'Disable HDR' option, which cancels all HDR metadata.
'Enable Custom HDR' stays on after power cycles; switch it off for SDR sources.

VERTEX DOLBY VISION SETUP — ALL STEPS →

Switch these off

Low LatencyNot needed for films. It is greyed out when Keystone is not 0 or Anamorphic is not Off.

How you know it works

Picture Adjust shows Gamma HDR(ST.2084) and Color Profile BT.2020 while LLDV plays, and the picture has full colour instead of a grey look.

Problems and fixes

LLDV looks washed out

Select Gamma HDR(ST.2084) and Color Profile BT.2020 by hand, or turn on the Vertex HDR InfoFrame.

Low Latency is greyed out

Keystone is not 0 or Anamorphic is on (JVC manual p.41).

Picture Mode does not switch to HDR with LLDV

Expected: the automatic switch needs an HDR signal. Select it by hand or use the Vertex HDR InfoFrame.

NOT CONFIRMED BY THE MANUFACTURER

An 'Auto Tone Mapping' option added by later firmware: its menu location on these models was not confirmed. JVC says it adapts to mastering data in the HDR stream, which LLDV does not carry.
How to create or load a custom gamma curve for LLDV: not covered by the JVC manual pages we checked.
Owners report that LLDV arrives as YCbCr 4:2:2 12-bit; HDfury's manual does not state this.
