OpenDisplay is a free, open-source pair of apps that turn an iPhone or iPad into a true extended second monitor for a Mac over USB or WiFi. It streams a virtual display with low-latency hardware H.264 encoding and supports Retina HiDPI, touch, scroll, and Apple Pencil input.
Use cases
- use iphone as second monitor for mac
- use ipad as extended display over usb
- free sidecar alternative without same apple id
- replace duet display subscription
- add a touchscreen monitor to macos
- extend mac display over wifi to ipad
- portrait vertical second screen for mac
When to choose
- you want a free, no-subscription, no-dongle second display for your Mac
- Sidecar fails because of Apple ID or hardware restrictions, or you want iPhone support
- you need USB-wired low latency or touch input on macOS
- you value self-hosted privacy with no accounts or cloud servers
When to avoid
- you need Windows, Linux, or Android device support
- you require production-grade reliability or enterprise support
- you need mirroring-only workflows better served by built-in AirPlay
- you need Apple Pencil features on iOS versions below the supported range
