OpenWinSidecar v0.1 — first public release.

Turn an iPad into a real extra monitor for Windows: an IddCx virtual display, hardware HEVC end-to-end (Intel Quick Sync → WebCodecs), touch/keyboard/gesture input, and live Windows DPI control — straight from Safari, no client app, no subscription.

Install

  1. Download OpenWinSidecar-Setup-0.1.0.exe below and run it (administrator).
  2. The installer registers the virtual display driver (creating the real extra monitor), installs FFmpeg (Gyan.FFmpeg) via winget if none is present, and adds a private-network firewall rule.
  3. Launch OpenWinSidecar, then on the iPad open http://<your-pc-ip>:8080 in Safari → Share → Add to Home Screen.

winget install --id julianmb.OpenWinSidecar will work once the winget-pkgs submission is approved.

Requirements

  • Windows 10/11 (x64). Intel Quick Sync is used for hardware HEVC; NVIDIA NVENC / AMD AMF profiles are auto-probed when QSV is unavailable.
  • FFmpeg is installed automatically at setup time; without it the stream degrades to JPEG (the app logs the install command).

Notes

  • Verified installer flow: driver device-node creation on clean machines, vdd_settings.xml deployment with automatic backup, and clean uninstall (device node, DriverStore package, firewall rule).
  • See CHANGELOG.md for the full engineering log.

Verify your download

The installer is not code-signed yet, so SmartScreen may show "Windows protected your PC" — choose More info → Run anyway after checking the hash:

SHA-256: 6e2aa1506c43cdc2420877b6d1ef587ba97f047cfc0a981fb7aa94b247034beb

Verify in PowerShell:

Get-FileHash .OpenWinSidecar-Setup-0.1.0.exe -Algorithm SHA256

The same value is recorded in this release's winget manifest (julianmb.OpenWinSidecar), and the build history is documented in the CHANGELOG.
