For this week's giveaway, we've teamed up with Astropad to offer MacRumors readers a chance to win a Luna Display adapter that can turn an extra Mac or an iPad into a secondary display to be used with a main Mac.

The inch-long Luna Display adapter plugs into a Mac using a USB-C port (on newer Macs) or a Mini DisplayPort (on older Macs) and then when paired with the Luna Display software, your primary Mac can be connected to an iPad or another Mac over Wifi, providing new ways to utilize old hardware or to add extra displays without having to invest in new products.

When connected, the Luna Display is able to extend the primary Mac's display to the secondary Mac or the iPad to allow the extra device to be used as a second screen, a feature that can be extra useful these days as people continue to figure out their work from home setups with makeshift offices.

Available for $70, the Luna Display sets itself apart from Apple's Sidecar functionality with the Mac-to-Mac support, which Sidecar can't do. The Mac-to-Mac feature was introduced after Sidecar and it makes the Luna Display adapter more powerful than Apple's solution. Luna Display is also able to work with older iPads that aren't supported by Sidecar.

When used in Mac-to-Mac mode, the primary Mac needs to be running macOS El Capitan or later, while the secondary Mac can be running macOS Mountain Lion or later, so you can use the Luna Display with some machines that are quite a bit older. For the best performance, the main Mac should be a 2012 MacBook Air or later, a 2012 MacBook Pro or later, a 2012 Mac mini or later, a 2012 iMac or later, or a 2013 Mac Pro or later.

Luna Display offers full keyboard, trackpad, and mouse support on both Macs when used in Mac-to-Mac mode, and more information on using Luna Display with dual Macs can be found on the Luna Display website.
As for iPads, the Luna Display is compatible with almost all modern iPads, including the the iPad 2 or later, all iPad mini models, all iPad Pro models, and all iPad Air models, with iOS 9.1 or later as the only requirement. Performance is faster on newer iPads, but older models work well too.

Right now, Astropad's Luna Display is compatible only with Macs, but later this year, the company is planning to debut Windows support for the first time in an effort to reach more customers and further diversify its product lineup after the launch of Apple's Sidecar. Check out Astropad's recent blog post for more info on the Windows-based products that are coming.

love to see a shootout between all three. The good, the bad, and the ugly.
Does exactly what I need it for during working hours. Quit the Luna app, and then the iMac becomes my home machine again. Definitely recommended for this use case.
Started with Duet. Runs on 10.9+ It was a great app and ahead of its time. Having my Ipad Pro as a second screen was very useful when traveling. Its biggest pro was it was the first, when they went to subscription the base app offered no real value over Sidecar; other than it works with more devices. Can't see spending money for the base version since Sidecar already does what the base version does; unless you use a device other than an iPad. $20/year for wireless or $30/year for touch support is simply not worth it to me as I found I never use that feature enough to make it worthwhile.
Luna Display. Runs on 10.11+ Bought on Kickstarter. I found it faster and more responsive than Luna. Pros are most pay features from Duet are included in the purchase. Mac to Mac and Headless mode. Wireless. Has touch support, I used it to add the Touchbar to my iPad before I bought a Touchbar Mac; but never really found the touch support that useful. Main use was to scroll with an Apple Pencil. Headless mode makes a Mini more flexible as you do not need to connect a monitor to it if you are using it as a server. Cons: Price is high upfront. Dongle covers a lot of plug space so two large plugs won't fit side to side. Plays videos well.
Sidecar: Catalina. Very basic functionality but it works if your main use is a second monitor to display documents, etc that are mostly static. Cons: No touch support if that is what you want. Mac/iPad only.
Cons on all: Only run on relatively new Macs. I've never found wireless to be that useful due to lags.
My recommendation: If you want touch support or us a pre-Catalina Mac go with the LunaDisplay. Although it is more upfront its payback is about 2.5 years and I've found it a better experience than Duet.
