It might take you a while to figure out that it actually work very well

I bought this one year ago. Then I tested it after reading many reviews, but what bothers me is, once the screen is on idle, I always have to walk to the main hub(Mac, laptop,etc) to wake it up in order to reactivate the Luna display connection to my iPad, otherwise the iPad Luna display just gonna keep trying to connect forever. Until after several months, several try, I finally figured it out. You need a Bluetooth mouse that is connected to the main hub(Mac, laptop,etc), and you bring the mouse with you wherever you use the iPad. Then every time when Luna display is launched on the iPad, I just move the mouse at my hand to wake the idled main hub(in another room) up, then the connection will establish in my iPad beautifully. Now I love it, I can bring my iPad(with the main hub mouse) and go to any room of my house, it always work(in rare cases, at most, it need a relaunch of the Luna display on the iPad, it will reconnect). I can continue to use my Mac mini, without buying another laptop for the mobility at home!

Amazing product design

These guys are fantastic; they really know good design! I guess that’s what you can expect from ex-Apple employees. The user interface & user experience is top-notch. I just tried my Luna out and it works great! Super responsive with very clear Retina graphics. I guess it helps that I have a good WiFi connection. It’s nice that the Luna app comes with a software tool to let you track the product performance in real time (latency, etc). Note that Luna on your iPad doesn’t work with pressure-sensitive styluses unless you also get the AstroPad product, which I already had. But when you combine Luna with AstroPad you can use the pressure-sensitive feature on your stylus and its an amazing experience! In that case, you open the AstroPad app on your devices rather than the Luna app. But thanks to the Luna app, with that setup you can continue to use your iPad as a second display. This really is the ultimate setup. It’s a great way to take your Mac and your iPad and combine them to have a touch-enabled drawing pad that works with Apple Pencil. And much cheaper than buying a Wacom drawing pad or a second monitor with touch/draw capability.

Absolutely in love.

I have only started using Luna Display for less than an hour, and I can already say that it’s the best second display app by far (over Duet Display I have used for more than a year).

The quality of the screen is amazing especially for the Retina resolution. It’s so, so crisp 🤤. Text and photos look amazing on Luna Display. When content changes quickly, Luna chooses to maintain frame rate instead of the rendering quality, so you may see coarse frames for a brief moment, and that’s a fine approach Astro took.

Color accuracy is insane. Photos on Luna look indistinguishable from photos on native iPad when looking at them side by side (with Slide-Over). I can see why artists absolutely love Luna Display for this.

One big plus for Luna Display is that you can switch apps on iPad from Luna Display to another app, and then back to Luna Display again, and it wouldn’t lose the connection. I do this often as a developer. This is something that, so far, only Luna Display can deliver and such continuity feels so amazing. EDIT: this is actually not true. Luna will lose connection once iOS puts in in the background. However, this is not what Luna advertises.

MORE EDIT: Luna Display almost always needs a cable to work well for me. This can be a drawback for many, but not for me personally, so I still enjoy Luna immensely.

Thank you Astro HQ. I am absolutely in love with Luna Display ❤️.
