RayNeo’s GT, GT Max, and Air series glasses are external-display glasses. They have no standalone operating system, and they need a video source plugged in over USB-C. That source’s USB-C port has to support a video standard called DisplayPort Alt Mode. A Lightning iPhone or iPad doesn’t have a USB-C port at all, so there’s no cable that connects it directly to the glasses.
Connecting one of these devices means routing the signal through two adapters in sequence: Apple’s Lightning Digital AV Adapter, then RayNeo’s HDMI Adapter, with an HDMI connection between them. Both adapters are sold separately from the glasses. RayNeo’s product page for the HDMI Adapter says so directly: “Devices with a Lightning port need an extra Lightning Digital AV Adapter from Apple, package not included.”
This guide covers why the direct connection doesn’t exist, which devices it affects, the chain in the order you plug things in, and what to expect from picture quality. For the full device-by-device matrix across phones, tablets, computers, and consoles, see the RayNeo GT and GT Max device compatibility guide; this page goes deeper on the Lightning case.
RayNeo’s glasses receive their picture through a single USB-C port that expects video, data, and power over DisplayPort Alt Mode. That’s the signal path an iPhone 15 or newer, many recent Android phones, and current USB-C iPads use, which is why those devices connect with the cable included in the box. A Lightning port doesn’t carry that signal, so a Lightning device needs an intermediate step that converts its output to HDMI before the glasses’ USB-C connection can use it.
This is a different situation from the iPhone 16e or iPhone Air, which have USB-C ports but aren’t on RayNeo’s list of supported devices for direct connection. Check RayNeo’s current compatibility list before assuming an adapter will solve that case.
| Device | Examples | Port type |
|---|---|---|
| iPhone 14 and earlier | iPhone 14, 13, 12, SE | Lightning |
| iPad 4th through 9th generation | Standard iPad models from roughly 2012 through 2021 | Lightning |
| iPad mini 1st through 5th generation | iPad mini through the 2019 model | Lightning |
The iPad mini 6th and 7th generations use USB-C. If you’re relying on one of them, confirm its video-output support with RayNeo support before buying adapters, since RayNeo’s compatibility list doesn’t name those two generations.
This is Apple’s own accessory, sold at Apple’s store, not through RayNeo. One end plugs into the Lightning port on your iPhone or iPad. The other end is a female HDMI port, with a second Lightning port on the adapter for pass-through charging. Apple lists support for mirrored output up to 1080p.
The RayNeo HDMI Adapter takes an HDMI input and converts it to a USB-C output the glasses can read, and it also handles power for the glasses. RayNeo’s product page lists output options of up to 4K at 30Hz or 1080p at 120Hz; confirm the current figures on the page. In this chain, the adapter simply receives whatever HDMI signal Apple’s adapter produces.
The same RayNeo accessory is used for:
See the RayNeo GT and GT Max device compatibility guide for the full breakdown.
Apple’s adapter outputs HDMI and RayNeo’s adapter accepts HDMI input, so an HDMI cable has to bridge the two. Neither product page confirms that one ships in the box, so if you don’t have a spare, order one alongside the adapters.
None of these steps involve the RayNeo app, so basic video output doesn’t require opening an app first. The app becomes relevant for features layered on top, such as app-based SBS 3D video playback, which has its own device and OS requirements; AI 2D-to-3D conversion isn’t listed for this Lightning route.
Power is described in two ways in RayNeo’s materials: one page says the adapter is “powered by the source device,” and a RayNeo blog post describes it as merging the HDMI signal with “an external USB power source.” Follow the guide that comes with your adapter. If it calls for external power, use a USB-C power source suitable for that port, and keep one on hand in case your setup needs it.
Apple’s Lightning Digital AV Adapter converts the signal before it reaches HDMI, and Apple lists mirrored output up to 1080p, so mirrored text and interface elements may not look identical to a direct USB-C connection from an iPhone 15 or newer.
Because the signal is converted along the way, cursor and touch response may differ from a direct connection, and neither RayNeo nor Apple publishes a quality or latency comparison for this chain. Judge it for yourself once you have the adapters, especially if you plan to do more than watch video.
Some third-party retail listings for RayNeo’s HDMI Adapter use language such as “Lightning & HDMI Input Support.” RayNeo’s own product page states that Lightning devices need Apple’s separate adapter. Treat RayNeo’s page as the deciding source and plan on both adapters regardless of how a marketplace listing titles the product.
| Item | When you need it |
|---|---|
| Apple Lightning Digital AV Adapter | Always, for any Lightning device |
| RayNeo HDMI Adapter | Always |
| HDMI cable | Unless you already have a spare |
| USB-C cable to the glasses | Use the one that came with your glasses |
| USB-C power source | If your adapter’s instructions call for external power |
Prices change, so check the current price of each item on Apple’s store and RayNeo’s product page rather than relying on a total quoted here.
If a Lightning iPhone or older iPad is the only device you own that could drive the glasses, this is the path that exists today. If you also own a laptop, a recent Android phone, or a USB-C iPad, check whether that device’s USB-C port supports DisplayPort video output first. A direct connection through one of those needs only the included USB-C cable and skips the conversion step described above.
Yes. RayNeo’s HDMI Adapter is the same accessory across GT, GT Max, and the Air series, and RayNeo’s own bundle listings pair it with Air 4 Pro. If you’re deciding between GT and GT Max and you’re on a Lightning iPhone, the adapter chain is identical either way; the choice comes down to screen size, field of view, and IPD fit. The GT vs. GT Max comparison covers those differences.
Does Apple’s adapter come with an HDMI cable included? Neither product page confirms that an HDMI cable is included with either adapter, so plan to supply one. The chain carries video at the resolutions the adapters support, so a standard HDMI cable is generally sufficient, and a short one is usually plenty because both adapters sit close together near your phone or tablet.
Will this setup drain my iPhone’s battery faster than normal? Possibly. RayNeo’s materials note that the connected device powers the glasses and processes video on a direct connection, and an adapter chain adds more hardware on top. Keep a power source available for anything beyond a short session.
Can I use a third-party Lightning to HDMI adapter instead of Apple’s? RayNeo’s product page names Apple’s adapter specifically and doesn’t confirm other brands. Sticking with the Apple adapter is the safer choice until RayNeo says otherwise.
Do I need the RayNeo app on an older Lightning iPhone? Not for basic video output. The app matters for extras such as app-based SBS 3D video playback, which has its own iOS and device requirements; AI 2D-to-3D conversion isn’t listed for the Lightning route. Check RayNeo’s current requirements for those extras.
Does the iPhone 16e, 17e, or iPhone Air work with this adapter chain? These models have USB-C ports, so there’s no Lightning connector for Apple’s adapter to plug into. They also aren’t on RayNeo’s list of supported devices for direct connection. Check RayNeo’s compatibility guide and support before buying any accessory for one of these phones.
If your only device is an iPhone 14 or earlier, or an older Lightning iPad, plan for the full chain: Apple’s adapter, an HDMI cable, RayNeo’s HDMI Adapter, and the power arrangement described above. If you have a second device with a USB-C port that outputs video, such as a recent laptop, start there instead, since it skips the conversion step.
