Per-Window Streaming

Every app becomes its own floating 3D panel. Not a screen mirror — Ethereal captures each window individually and streams it to your Quest headset.

Screen Mirroring vs Per-Window Streaming

Screen Mirroring

  • ✕ One flat panel showing your entire desktop
  • ✕ You see everything on your screen at once
  • ✕ Limited arrangement — fixed virtual monitors
  • ✕ Apps stuck in monitor boundaries

Per-Window Streaming

  • ✓ Each app is its own independent panel
  • ✓ Resize each window individually
  • ✓ Arrange anywhere in 3D space
  • ✓ No monitor boundaries — windows float freely

How It Works

The Ethereal Host app on your PC or Mac captures each window independently using platform-native APIs. On Windows, it uses the native window capture API. On macOS, it leverages ScreenCaptureKit for efficient, low-overhead capture.

Each window is encoded separately using hardware-accelerated encoding and streamed directly to your Quest headset. This per-window architecture means every app gets its own video stream — so you can resize, reposition, and interact with each panel independently.

The result: under 20ms latency from your PC to your Quest. Your windows feel native, not remote. No virtual monitors, no screen mirroring — just your actual apps floating in space.

Benefits

📌

True Spatial Layout

Place your browser above your IDE, pin Slack to the left, put Spotify behind you. Every window goes exactly where you want it in 3D space.

↔

Independent Resizing

Make your code editor huge and your chat window small. Each panel resizes independently — no one-size-fits-all virtual monitor.

👁

Mixed Reality Ready

Individual panels look natural in passthrough mode. Your real desk, keyboard, and coffee plus floating apps — the best of both worlds.

◻

No Monitor Boundaries

Apps aren't trapped in virtual monitors. Every window floats freely in your space. No edges, no bezels, no limits.
