Luna Display 5.1 adds the ability to use any Mac as a wireless second display for a PC. And that’s just one of the new features in the update, which also adds support for using a 4K or 5K computer as a second screen.

These features build on this device’s basic ability to turn an iPad into a Mac display.

What’s new in Luna Display 5.1

In October, the plug-in Luna Display wireless adapter gained the ability to let Windows PC users to make their iPad into a second screen. The 5.1 software update extends that to PCs and Macs. The product already allowed a Mac to function as a second screen for another Mac.

In addition, the update adds support for using Apple’s Magic Keyboard and trackpad with an iPad functioning as the external display. This new feature works for both Mac and PC.

Those using Luna Display in the same area as other users will appreciate Office Mode for PC. It lets users make a manual connection instead of automatically connecting to the first computer it finds on the network.

In addition, the latest update adds Teleprompter Mode for PC for use with a beam splitter.

The free Luna Display application is available on the App Store. Mac or Windows software is also necessary.

But using them requires the Luna Display wireless adapter. There’s a USB-C version for Mac and PC, a Mini DisplayPort one for Mac and an HDMI version for PC.

There are other software/hardware options for using an iPad or Mac as a second screen, like Apple’s own Sidecar. But Luna Display offers some of the best performance available, with a high screen refresh rate and low latency.
