Agent Skills: Varjo XR-4 Series (Device Profile)

Varjo XR-4 Series (Device Profile)

Use when the user targets Varjo XR-4 / XR-4 Focal Edition / XR-4 Secure Edition.

What Matters Most

• Wide-gamut mini-LED displays (98% sRGB / 96% DCI-P3) and high PPD (up to 51)
• Windows + Varjo Base is the control plane
• OpenXR is the default modern API target; OpenVR is still relevant for SteamVR apps
• Tracking mode choice changes your deployment: inside-out vs base-station (SteamVR)

Setup + Runtime

• Install Varjo Base.
• If prompted, enable OpenXR and OpenVR runtimes (needed for OpenXR apps and SteamVR/OpenVR apps).

Tracking Options

• Inside-out tracking (no base stations)
• SteamVR Tracking on base station tracking variants (base stations + optional controllers/trackers)
• Third-party tracking (ART/OptiTrack) via API integrations

Refresh Rate (Practical)

• Typical options are 75 Hz or 90 Hz (configured in Varjo Base).
• 90 Hz is the safer default for VR comfort if you can hit frame rate; 75 Hz can reduce GPU load.

Color / Rendering Notes

• XR-4 has high DCI-P3 coverage; for color-critical work, validate your look in-headset.
• Treat wide-gamut as a display capability, not a guarantee of correct color: calibration, tone mapping, and content decisions still matter.

Good “First Questions” For XR-4 Work

Ask up to 3 (only if needed):

1. Are we targeting OpenXR (recommended) or SteamVR/OpenVR legacy content?
2. Which tracking variant do you have: inside-out only or XR-4 base station tracking?
3. What’s the priority: max fidelity (PPD) or stable frame time (comfort)?
