Why Ext Screen?
Transform your iPad into a professional external monitor and teaching tool! Designed specifically for iPad, this app allows you to easily connect and display high-quality video from external USB-C webcams. Whether you are conducting online classes, demonstrating products, using it as a document camera, or acting as a secondary monitor for photography, it delivers a smooth, ultra-low latency experience.
Understanding the needs of creators and educators, we have integrated powerful “Live Drawing” and “Screen Control” features. You can write and highlight directly on the live video feed, and adjust the zoom and orientation at any time. To provide the purest viewing experience, the user interface automatically hides when idle, letting you focus entirely on the content.
Key Features:
- Smart Auto-Hiding UI: The top menu smoothly fades out after 10 seconds of inactivity, providing a distraction-free, full-screen view. A simple tap anywhere on the screen instantly wakes up the controls.
- Plug & Play External Cameras: Seamlessly supports USB-C external webcams, USB-C HDMI Adaptor and built-in iPad cameras, with automatic detection and easy switching.
- Full-Screen Edge-to-Edge Display: Video automatically fills your iPad screen with the optimal aspect ratio for an immersive viewing experience.
- Intuitive Gesture Zoom: Supports pinch-to-zoom to inspect details up to 5x magnification. Simply double-tap the screen to quickly restore the original size.
- Live On-Screen Annotation: Features a powerful drawing mode with 6 vibrant pen colors. Write and highlight directly on the live feed, complete with undo and clear-all functions—perfect for teaching and presentations.
- Flexible Screen Controls:
One-Tap Mirroring: Instantly flip the video horizontally to ensure your movements align with the display. - Orientation Correction: Easily rotate the video in 90-degree increments to fix default orientation issues common with various webcam brands, keeping your view always upright.
