Luna Display - Second Display Hardware

Mostly Very Satisfied

I’m mostly very satisfied with the Luna after using for a couple of weeks. I’m using a 2026 Mac Book Pro M5 running Tahoe (26.5.2) and connecting to a 2017 iMac that tops out at Ventura (13.7.8) -so I can’t connect directly with the iMac (it needs OS 15). I connect via Ethernet – my MacBook Pro connects to Ethernet via a Thunderbolt Hub and the iMac is connected directly to my router. The Ethernet connection for Luna works very well – it does everything I need it to (email, word processing, Internet and photo editing for the most part). I’m not so sure about using it for videos. And connecting via my wi-fi doesn’t work – when scrolling or screen rendering there’s a lag-time where the text is blurry. It took me some experimenting to find how to position the two monitors so that the mouse cursor didn’t disappear when I moved between the monitors. Playing around with all the various options, particularly Arrange, was useful. For the most part, Luna remembers the position of the windows when I reconnect after I’ve moved to the iMac after disconnecting the MB Pro to work untethered. It works best for me to quit Luna Secondary on the iMac before letting the Primary sleep – when I let the primary computer sleep with the iMac connected, the iMac is inconsistent in dimming completely (the two support articles on this subject didn’t resolve the issue for me); I also twice had to quit and restart Luna on the primary. It works best if I hide everything on the iMac before leaving a work session and closing the Mac Book Pro (primary) to sleep it – otherwise I sometimes need to rearrange windows back to where I want them upon reconnecting. One thing: the iMac has a native resolution of up to 5120 x 2880 but the best I can do with Luna with “Retina Resolution” enabled. is 2560 x 1440.) I wouldn’t use it for video editing. The bottom line: I’m very glad to have Luna – it keeps my iMac alive and saves the cost of buying a new external monitor. The 30-day return made trying it a no-brainer. It took a few days to get everything working correctly for me but it was worth it.

Repurposing an Older iMac Made Remarkably Simple

After using Luna for some time, I can say without reservation that it has exceeded my expectations. Like many Mac users, I had an older 27-inch iMac that was simply too good to discard, yet no longer practical as a primary computer. Luna transformed it into a second display for my newer Mac Studio with remarkable ease. Installation was uncomplicated, the software was intuitive, and within minutes the iMac had become an integral part of my workspace. What impressed me most was not merely that it worked, but how well it worked. Image quality is excellent, performance has been consistently smooth, and responsiveness has proven far better than I had anticipated. At no point has it felt like a compromise or an improvised solution. Instead, it behaves as though this capability had always been part of macOS. Repurposing quality hardware rather than allowing it to sit unused is immensely satisfying in its own right. Luna has given my iMac an entirely new lease on life while significantly improving both the efficiency and enjoyment of my daily workflow. It is refreshing to encounter a product that delivers precisely what it promises. Luna met every one of my hopeful expectations and has proven to be one of the most worthwhile additions to my Mac setup. I recommend it without hesitation to anyone looking to extend the useful life of an older iMac. Five stars, without qualification.

It works!!

Was looking for a solution to keep my Mac desktop as is, However still use it as a third screen for work, via laptop. Little bit of easy set up and screen configuration and then easy as! So far very happy with this and meets my expectations. 😀 And, AI email was great at following up re timing from US to Australia .
