Are you looking for ways to turn your iPad, tablet, or spare laptop into a secondary display for your main computer? While apps like Orion offer a convenient solution, their limitations and costs can be a barrier for some users. In this blog post, we'll explore the world of free screen mirroring apps, their features, and how to set up the most of them.

The Need for Orion Alternatives

There are Several reasons that lead individuals to seek alternatives to the Orion app for extending or mirroring their main display to an iPad or other devices:

1. Device Compatibility: Orion only works with modern iPads that have a USB-C port for connecting an HDMI adapter. Users with older iPads or other tablets need apps that support their specific devices.

   

2. Wireless Connectivity: While Orion requires a wired HDMI connection, some users prefer wireless solutions like Duet Display or Luna Display that can connect over Wi-Fi for more flexibility.

3. Additional Features: Apps like Duet Display and Luna Display offer extra capabilities beyond just mirroring, such as touch support, pressure sensitivity for Apple Pencil, and better desktop integration on Mac and Windows.

4. Cost: The free version of Orion has limited functionality. Paid alternatives like Duet Display ($9.99 one-time) or Luna Display ($59.99 one-time) may be preferable for users needing advanced features without recurring costs.

5. Performance: Some users report lag or quality issues with Orion's video upscaling and may seek higher-performance alternatives, especially for professional use cases.

6. Compatibility with Other Devices: Apps like iDisplay and Air Display support using tablets/phones as extended displays for a wider range of devices beyond just HDMI sources.

Limitations of Orion

While Orion is a convenient app for turning an iPad into an HDMI monitor, there are some limitations and potential issues to be aware of:

• Orion requires a USB-C iPad and a USB-C HDMI capture card, which adds extra cost and complexity compared to built-in screen mirroring features.
• Some users have reported audio issues like mono sound instead of stereo with Orion.
• There can be frame rate stutters and performance issues depending on the capture card used.
• Orion is only available on iOS, so Android users need to look for alternatives.
