Optoma UHZ35: Dolby Vision with the HDfury VRROOM
The Optoma UHZ35 supports HDR10, HLG — but has no native Dolby Vision decoder. Here is the exact HDfury VRROOM setup that gets Dolby-Vision–quality, scene-by-scene tone mapping onto it anyway.
The problem: HDR10, HLG, no Dolby Vision
Optoma’s own product pages describe their projectors as “capable of receiving and displaying both HDR10 and Hybrid Log Gamma (HLG) HDR content” — Dolby Vision is never part of that description. The Optoma UHZ35’s own Optoma official spec page lists HDR10, HLG — Dolby Vision is not among the supported formats.
The fix: the VRROOM’s LLDV enabler
Your source player does the actual Dolby Vision tone mapping, the VRROOM tells the player it’s allowed to do that, and your projector never has to do anything different at all.
1. Your player
Apple TV 4K, an Oppo or Panasonic Blu-ray player, a Kaleidescape, an NVIDIA Shield and others already know how to output Dolby Vision — they just need to see a display that claims Dolby Vision support in its EDID (that’s step 2). Exact per-player menu steps are in the player setup guides.
2. The VRROOM
Open the VRROOM’s web server, go to the EDID tab, and assign Custom EDID 5 (Sony A1 LLDV, DCI-P3) or Custom EDID 10 (Sony A1 LLDV, BT.2020) to the input your player is connected to — both are ready-made LLDV EDIDs, nothing else to configure. Then, in the HDR/AVI tab, turn on “Use custom HDR for TX0 and TX1 when input is LLDV.” Restart your player after changing the EDID. Full detail: the EDID section, the DV section and the HDR/AVI section of the manual, or the LLDV>HDR10 FAQ for the short version.
3. Your projector
Usually nothing at all — it only ever sees an HDR10 signal and displays it as HDR10. Leave it in its normal HDR10 picture mode. If it has its own dynamic, frame-by-frame HDR tone-mapping feature, most owners get a cleaner result leaving that off, since the player already did scene-by-scene tone mapping before the signal arrived.
On projectors without automatic HDR-mode switching you may need to force HDR mode manually, since LLDV does not always carry the same HDR info-frame as standard HDR10.
