The developers of the Duet Display app that allows the use of an iPad as an second screen for a Mac have released an update to the Pro in-app subscription, allowing for better color quality, better pressure curve customization, and more.

Users who have subscribed to service can now change the way that macOS receives and translates pressure curves, allowing for tailoring of how the Apple Pencil responds to the user. Additionally, to provide a faster drawing experience, Duet has implemented a "line preview" feature to predict where the Pencil is before macOS or Windows knows where it is.

Advanced gestures have been implemented in the new version, making drawing and using the iPad as a primary interface better for the user. Supplementing that, the virtual Touch Bar feature has been improved, with enhanced speed and stability.

Rendering quality and speed for pro users under the Pixel Perfect setting has been improved, delivering a higher quality display in less time according to the developers.

AppleInsider examined the core Duet Display app in December 2016, and found the $19.99 app "preposterously fast" in regular use, with nearly transparent extension of the macOS desktop after initial installation.

Duet Pro 2.0 is a $19.99 yearly in-app purchase, allowing for use of an iPad as a graphics tablet replacement, the ability for the Apple Pencil to be more than a simple pointer as in the core app, and implements palm rejection as well.

Duet Display and the Duet Pro 2.0 in-app purchase require iOS 8.0 or greater on the iPad, and macOS Sierra 10.12.2 or later.
