A desktop session from an Android phone is something the phone creates, not the glasses. Wired display glasses such as RayNeo GT and RayNeo GT Max take a DisplayPort video signal over USB-C, the same kind of signal a monitor receives. So the question that decides everything is whether the phone itself can open a desktop on an external display.
Two groups of phones can. Samsung Galaxy models on Samsung's wired DeX list open DeX on an external display, and Android 16 QPR3 (a quarterly platform update to Android 16) brings a connected-display desktop session to supported Pixel and Samsung phones. GT and GT Max work as a plug-and-play external display for screen mirroring or extended display, so the desktop the phone opens is the desktop that appears in the glasses.
Why the phone sets the rules
GT and GT Max connect directly over USB-C to devices that support DisplayPort video output, and the connected device powers the glasses and processes the video. The glasses are a 1920x1080 Micro-OLED screen with their own optics, spatial tracking, and speakers, while everything that runs (apps, windows, the taskbar) runs on the phone.
That split is why DeX is a phone-side question. Samsung's DeX, Android's desktop session, or a plain mirrored screen are all decisions the phone's software makes about an external display, and the glasses display the video signal the phone outputs.
RayNeo iO and RayNeo X3 Pro belong to different categories. iO is an AI glasses product that links to the phone over Bluetooth 5.4, and X3 Pro is a standalone AI+AR platform with its own processor and an Android-based environment for selected apps. Neither one is an external display for a phone desktop.
Which phones open a desktop session
The phone needs two things: wired video output over USB-C, and software that turns that output into a desktop instead of a mirror.
On the glasses side, the requirement is video output over USB-C. Devices that support DisplayPort over USB-C or DP Alt Mode connect directly to GT and GT Max with the included cable, and the Samsung Galaxy S8 to S25 series are examples of Android phones that do.
Google describes the Android 16 desktop session this way: when a supported phone connects to an external display, a new desktop session starts on that display with a taskbar and freely resizable windows, while the phone keeps its own screen and state. Google names the Pixel 8, 9, and 10 series and Samsung devices including the S26, Fold7, and Flip7 as supported.
On a Pixel 8 or later that is not yet on Android 16 QPR3 or later, a wired connection mirrors the full screen instead. Google's wired display option covers Pixel 8 and later, so older Pixel models, along with any phone whose USB-C port carries no video, take one of the paths in running AR glasses without USB-C DP Alt Mode.
Opening DeX from a Galaxy phone
The routine on a Galaxy phone on Samsung's wired DeX list:
-
Connect and unlock. Plug the glasses' included USB-C cable into the phone, with both ends fully inserted, and unlock the phone. The glasses turn on automatically when they detect a compatible power supply and video signal.
-
Start DeX. On first use, Samsung shows a popup with a Start button. Without the popup, a two-finger swipe down opens Quick settings, where the DeX icon starts it. Some phones begin by mirroring the screen and switch over through the Samsung DeX notification.
-
Pick a spatial viewing mode. A short press of the Spatial Mode Button on the glasses switches between Steady, Pinned, and Follow. Pinned keeps the screen fixed in one position for focused viewing, and pressing and holding the button in Pinned Mode recenters the desktop in front of you. Follow keeps the screen centered as you move your head, and Steady keeps it stable with subtle natural movement for travel and commuting.
-
Add a keyboard and mouse over Bluetooth. DeX supports a keyboard and mouse paired over Bluetooth, which turns the phone and glasses into a typing setup.
-
Run everything from one cable. GT and GT Max have no built-in battery and never need charging: the USB-C port receives power, video, and audio from the phone, and the included cable is the only accessory a phone with DisplayPort output needs. For long desktop sessions, the RayNeo USB-C Charging Adapter charges the phone over USB-C PD while the glasses stay connected.
One Samsung detail matters here. In One UI 8, display settings such as position, resolution, and rotation are saved separately for each connected display, so settings chosen for one display can reset after switching to another.
The glasses need no app for basic display use, which is why DeX runs straight from the phone. The RayNeo XR App is the media layer on top, with SBS 3D playback, AI 2D-to-3D, media import, and glasses settings, and on Samsung phones it runs in non-DeX mode, with DeX turned off in the phone's settings.
The full connection picture for each device type, including laptops and consoles, sits in the GT and GT Max device compatibility guide.
GT or GT Max for a pocket desktop
Both models share the 1920x1080 panel, 2D refresh up to 120Hz, and a display-mode list of Standard, Movie, Eye Protection, and Office. The difference for desktop work is how those pixels spread across your view.
GT packs the same 1080p image into a narrower field of view, which is where its 49 pixels per degree come from. For small text in a browser or a document, that density is what makes letters look crisp, so GT suits a desktop setup built around reading and writing. Its 68 grams also matter during a long typing session.
GT Max spreads the image across 59 degrees, so desktop windows feel physically larger and more of the desktop sits in view at once. That suits spreadsheets, side-by-side windows, and video between tasks. GT Max comes in S, M, and L IPD sizes, and choosing the size that matches your IPD, measured with a smartphone at ipd.rayneo.com, gives a clearer, more comfortable view.
For nearsighted users who spend the day reading documents, both models are prescription lens compatible. Custom lenses cover myopia from 0 to -10.00D and astigmatism up to -2.00D, ordered from RayNeo's lens partner Lensology or fitted at a local optical store using the prescription-lens sample frame included with the glasses.
For audio and video between tasks in a shared office or on a train, Whisper Mode reduces audio leakage, and the open-ear speakers direct sound toward the wearer so that it is difficult to hear clearly from about 1.5 meters away.
For Windows laptops rather than phones, the Windows external display guide covers extend and mirror settings on the PC side.
FAQ
Can an iPhone give me a DeX-style desktop on the glasses?
DeX is Samsung software and the connected-display desktop session is part of Android, so neither runs on an iPhone. Supported iPhones still connect to GT and GT Max directly over USB-C, and the RayNeo XR App adds AI 2D-to-3D and spatial photo and video viewing on them.
Can Pocket TV Pro act as the desktop instead of my phone?
Pocket TV Pro is RayNeo's Google TV player, built for streaming apps and local playback, with Dolby Vision on GT series glasses. It is the entertainment source in a RayNeo setup, while desktop work stays with a phone or a laptop.
Does a Galaxy phone need the RayNeo HDMI Adapter?
A Galaxy phone with DisplayPort output over USB-C connects to GT and GT Max directly with the included cable, without the adapter. The
RayNeo HDMI Adapter is the path for HDMI sources such as PS5, Xbox, desktop PCs, and laptops with HDMI output.
