When considering on-the-go workspace solutions, Luna Display and Duet Display are two Mac-friendly options to use your iPad as a second display. While Duet Display is a software-only app, Luna Display uses a unique hardware-and-software combination.
The guide below outlines the benefits of a hardware solution so that you can make an informed decision for your workflow:
True Display Recognition
The Mac recognizes Luna as a real display, which means you’ll get robust and reliable performance every time you use Luna.
Duet relies on software that “tricks” your Mac into thinking a display is attached, causing glitchy and unreliable performance. This also puts Duet’s software at risk of being unsupported when Apple releases future OS updates.
Full, Native Retina Resolutions
Luna Display can drive all iPads at the full, native Retina resolutions for Macs that support Retina mode.
Duet Display is limited to 1080p, which doesn’t necessarily fit the size of the iPad.
Complete GPU Acceleration
Because your computer recognizes Luna as a true display, Luna is able to harness the raw power of your computer's graphics card, allowing complete GPU acceleration across all apps. The result is an ultra-crisp picture and a perceptually-lossless display.
Mac computers are unable to recognize Duet as a true second display, so Duet gets inconsistent graphics acceleration and Metal GPU support. That’s like buying a car and only using half the engine.
From the beginning, Luna was designed to be used over WiFi. Luna runs on our proprietary display protocol, called LIQUID, that was built to provide low-latency and high-resolution on WiFi networks. LIQUID’S algorithm features our built-in Velocity Control, which analyzes WiFi network conditions dozens of times per second to balance image quality and latency. Luna typically sees latency of 16 to 32 milliseconds (ms) over WiFi.
Duet relies on AirPlay to run wirelessly, which typically sees latency of 32 to 64ms.
The Hardware Advantage
Luna is a real hardware display. Software-simulated displays like Duet are limited and offer an unreliable display experience.
