Here's the game-changer for me. Duet Display, despite its technical achievements, always felt clunky because you had to plug your iPad into your Mac to make it work. Working at a café, I often felt one step away from the folks who brought in iMacs with external keyboards and mice —when your electronics and wires are taking up more of the table than your food or beverages, you've basically created a mini-office for yourself. To be accurate, the Luna Display update to version 5.0 adds support for Windows PCs. So if you already have a Luna, wait for the update, and you’re all set. Luna Display lags. I'm not exactly sure how the Liquid Technology works, but I see a significant blur effect whenever I move any Mac program or app around on my iPad. This does not happen when I use Duet Display.

But, even when I connect my MacBook Pro to my iPad Pro using Luna Display and a wired USB connection, I get the same blur effect. It's not the fault of the wireless connection. This does not happen when I use a wired connection with Duet Display, either. The Luna Display extends a Mac or PC's display to a secondary Mac or ‌iPad‌. There's an ‌iPad‌ to Mac mode, an ‌iPad‌ to PC mode, a Mac to Mac mode, and a PC to Mac mode. For the USB-C version of the Luna Display, it can be used interchangeably between Macs and PCs thanks to a software update that came out earlier this year. Luna makes a small dongle that sends the signal to your iPad, enabling it to act as a secondary display for those new to the product. Those dongles are available in USB-C, Mini DisplayPort, or HDMI. So make sure you’re on the latest software, plug the dongle into your PC with HDMI or USB-C, and give it a try.Apple has designed a Sidecar function for using an ‌iPad‌ as a secondary device for a Mac, but it's much more limited than what Luna Display can do because it only works with a Mac and an ‌iPad‌. Luna Display supports Mac-to-Mac, PC-to-Mac, and PC-to-iPad connectivity in addition to Mac-to-iPad functionality. While the Luna app doesn't have all of Astropad's many touch features built in, it still offers a fair amount of multitouch support for interacting with macOS: You can tap to select or tap and drag to resize windows; two-finger drag to scroll through windows; and two-finger pinch or spread to zoom.

Luna Display from Astropad is a neat product that turns your iPad into a wireless second display monitor. And while it was initially only available for the Mac, this week, the company announced full support for Windows machines, making it more useful than ever. Yes, this little gadget will turn your iPad into a wireless second monitor for a Windows PC. It's also worth noting that ‌Sidecar‌ is limited to newer devices, while Luna Display is compatible with older iPads and Macs that don't support the ‌Sidecar‌ feature. Luna Display also offers full native resolution, which is not available with the Mac to Mac AirPlay feature that Apple added in macOS Monterey, plus it connects over Ethernet or Thunderbolt in addition to WiFi for faster speeds. On a 10.5-inch iPad Pro, that means the option of having 1112x834 HiDPI (2x) resolution, or using the iPad's full pixel grid to run a 2224x1668 monitor. The latter option can be a little small for people with poor eyesight, but it's an amazing alternative to have while on the road, especially if you need more space than a laptop screen can provide. Of course, the best thing about the Luna Display is that it's wireless. I can set my iPad on a completely different desk or table and still use it as a second screen. Moving apps and programs across my Mac to my iPad works seamlessly. I can take my iPad into a different room and continue to work with Mac programs on my iPad. As long as they're both connected to the same wi-fi, I can use the second screen feature.Please note: Your information is not shared or stored by Astropad and Luna Display does not record or save the contents of your screen.** I've used wireless software that has much worse glitching, blinking, and lagging. Luna Display is definitely better. With this setup, you can take advantage of older hardware or add an extra display to your workflow without having to spend money on another device. It's especially useful for those who have makeshift work-from-home setups that could make use of an extra device. The dongle works with 2013 and newer Macs running macOS 10.11 El Capitan or later, as well as iPads running iOS 9.1 or later.
