Duet Display is a software tool that uses also uses a hardware connection to allow Mac users to utilize their iPads as an extra display, either mirroring or extending their desktop. Now that Apple has built a similar function into macOS Catalina, Duet Display is releasing an Android version of its software.
The app has previously worked with Windows, but did so by extending the PC screen onto iPads. Now its new version will be able to use Android tablets instead. It’s not clear yet whether the software will allow Windows PCs to have their screens extended onto iPads, however.
