Start by identifying whether you have a wireless PC Connect problem or a wired video problem. Wireless PC Connect needs a Windows 10-or-newer computer, an Android XR device, the PC Connect software on both, and the same Wi-Fi network. Wired glasses need a real video signal—usually DisplayPort Alternate Mode over USB-C or Thunderbolt 4—not merely a USB-C plug that supplies charging or data.
Follow the checks below in order. They separate an incompatible host port from a bad cable, missing power, a hub or adapter problem, an operating-system setting, and an emulator-pairing fault.

Identify the connection path before changing anything
Android XR is a platform, not one universal pair of glasses. Physical products from different manufacturers can use different firmware, power arrangements, supported resolutions and adapter rules. Use the exact model manual alongside these general checks.
| What you are trying to do | Connection type | Minimum condition to verify first |
|---|---|---|
| Stream a computer view wirelessly to an Android XR device | Android XR PC Connect | Windows 10 or newer, PC Connect installed on the computer and headset, and both devices on the same Wi-Fi network |
| Show a phone, tablet, laptop or handheld screen through a USB-C cable | Direct wired video | The host USB-C port supports DisplayPort Alternate Mode; Thunderbolt 4 also provides a compatible video path |
| Show a desktop GPU, console or other HDMI/DisplayPort source | Powered dock or adapter | Video enters the dock through HDMI or DisplayPort, USB power/data are connected as required, and USB-C video leaves the dock for the glasses |
| Pair Android XR emulator instances | Android Studio emulator connection | Both emulators can be stopped, cold-booted, reset and paired again through Android settings |
A USB-C connector describes the shape of the plug, not the capabilities of the port. A port can charge a device and transfer files while lacking any DisplayPort output.

- 【Strong Adsorption】The inspiration of the silicone phone suction case comes from the adhesive force of the octopus. Each suction cup phone mount is 3.15 inches long and 2.17 inches wide, with 24 independent suction cups providing a stronger and more stable suction force, so you don't have to worry about your phone falling during use.
- 【Back of Phone Suction Grip】Remove the adhesive film on the phone suction cup and stick it on the phone case. You can then fix the phone on any smooth surface, which is very convenient. (The phone suction cup cannot be removed and reused after being attached to the phone case. It is recommended to attach it to a regular phone case, not a valuable one.)
- 【Widely Used】Our non-slip silicone phone sticky grip mount attaches to almost any flat phone case and make it compatible with common mobile phones such as iPhone and Android.You can shoot, watch videos or video calls in the kitchen, gym, dance studio, bathroom and other places.
- 【Capture the Wonderful Picture】Whether you are a TikTok creator or just like to share videos and photos, this phone suction cup can help you hands-free capture wonderful videos and photos for sharing with friends.
- 【Note】You can fix the phone suction cup on a smooth surface such as a mirror or glass. If necessary, wipe the suction cup with a damp cloth to obtain stronger suction. Before releasing your hand, make sure the phone is firmly fixed. (Not applicable to rough walls, wooden surfaces, and other uneven surfaces)
A fast decision tree
- If you are trying to stream from Windows without a cable, use the PC Connect checks first. Do not troubleshoot it as if it were a dead USB-C display.
- If the glasses are connected by USB-C, confirm the host port’s video specification before buying another cable. No passive cable can create a DisplayPort signal from a charging-only port.
- If the source has only HDMI or full-size DisplayPort, plan for a powered, active XR dock rather than a gender changer or charging adapter.
- If the glasses power on but the image is black, treat power and video as separate questions: the first proves only that the glasses receive enough power to start.
- If this is an Android Studio setup, stop changing retail-hardware cables and use the emulator recovery sequence later in this guide.
Wireless PC Connect: make the computer discoverable
Google’s Android XR PC Connect workflow is separate from a cable-based display connection. The computer and Android XR device must be on the same Wi-Fi network, and PC Connect must be installed on both sides.
- Install PC Connect on the Android XR device and on the compatible Windows computer.
- Connect both devices to the same Wi-Fi network. A guest network, client isolation or a VPN that separates local devices can prevent discovery even when both devices appear to have internet access.
- Open the PC Connect feature in the headset or glasses app and select the computer when it appears.
- Pair the devices by scanning the QR code shown on the computer or by confirming that the PIN displayed on each device matches.
- Accept the request on both devices. Streaming should begin automatically after the confirmations are complete.
If the computer never appears
- Confirm the computer is running Windows 10 or newer and that PC Connect is installed and open.
- Recheck the Wi-Fi name on both devices rather than assuming that two different access points are part of the same local network.
- Temporarily disconnect a VPN and check whether the router blocks device-to-device traffic.
- Quit and reopen PC Connect on the computer, then reopen the headset app and search again.
- When discovery succeeds but pairing fails, rescan the current QR code or enter the newly displayed PIN; do not reuse an older code.
Discovery and pairing are separate stages. A computer appearing in the list proves that local discovery worked, but streaming still waits for the QR or PIN confirmation on both devices. Conversely, a valid PIN cannot help if the two devices are isolated on different networks.
Wired troubleshooting: verify that the host can send video
Check the exact port specification
Look up the specification for the exact phone, tablet, laptop, handheld, desktop motherboard or graphics card. The wording to find is DisplayPort Alternate Mode over USB-C, often abbreviated DP Alt Mode. Thunderbolt 4 is another compatible route for direct USB-C display output. A specification that lists only charging, USB data, or USB 2.0/3.x does not establish video support.
RayNeo’s phone guidance states that its XR glasses work with Android phones that support DisplayPort. The same principle applies to other direct USB-C glasses: charging current reaching the glasses is not evidence that a DisplayPort signal is present.
Check the port on the actual device, not only the product family name. Two phones in the same series, or two USB-C sockets on one computer, can have different capabilities. A manufacturer’s manual or technical specification is stronger evidence than a retailer listing that merely says “USB-C.”
Use a video-capable cable
Start with the cable supplied with the glasses when it is available. Otherwise use a full-featured USB-C cable explicitly rated for DisplayPort video. Disconnect both ends, inspect the plugs and sockets for debris or damage, then reconnect firmly at the host and glasses. XREAL’s troubleshooting sequence also recommends trying another approved cable or another compatible source.
A cable can fit perfectly while carrying only power and data. If the glasses show a logo and then a black screen, or never switch to an external display, substitute a known video-rated cable before assuming the glasses are defective. During testing, avoid extension cables and unusually long runs because they add another possible signal or power failure point.

- SUPERIOR COMFORT — Unlike traditional circular ear buds, the design of EarPods is defined by the geometry of the ear. Which makes them more comfortable for more people than any other ear bud–style headphones.
- HIGH-QUALITY AUDIO — The speakers inside EarPods have been engineered to maximize sound output and minimize sound loss, which means you get high-quality audio.
- BUILT-IN REMOTE — EarPods with USB-C plug also include a built-in remote that lets you adjust the volume, control the playback of music and video, and answer or end calls with a pinch of the cord.
- COMPATIBILITY — Works with all devices that have a USB-C port.
- INTEGRATED MICROPHONE — A built-in microphone precisely captures your voice while you’re on the phone, taking a FaceTime call, or summoning Siri — so you’re always heard loud and clear.
Remove hubs while diagnosing
Connect the glasses directly to the host whenever possible. Bypass USB hubs, monitor docks, extension cables and unpowered adapters for the first test. Each additional device can alter USB-C negotiation, consume power or fail to pass the DisplayPort lanes required by the glasses.
Wake and unlock the host. Check its external-display controls after the cable is connected; some operating systems keep an external output disabled until the device is unlocked or a display mode is selected.
Confirm the power path
Some glasses draw their operating power from the host, while adapter-based setups require a separate supply. Check that the host is awake, the dock is powered and every required USB power lead is connected. Some XREAL connection documentation gives 5 V/1 A power guidance for particular setups; treat that as a model-specific requirement, not a universal specification for every Android XR product.
If the glasses do not light up at all, power delivery, the cable, or the dock is a more immediate suspect than display settings. If they power on but show no picture, continue with the video-signal checks.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Restart and isolate the failing component
- Disconnect the glasses from the host or dock.
- Restart the source device completely rather than merely closing the display settings.
- Reconnect the glasses directly, using the approved cable and no hub.
- Allow the source operating system to finish booting, unlock it, and check for an external-display notification or setting.
- Test the glasses on another known-compatible DisplayPort-output device.
- Test the original source with another known-good video cable or display.
These cross-tests identify the side that follows the fault. If the glasses fail on two compatible sources, document the result for the glasses manufacturer. If another display also fails on the original host port, investigate the host, its driver or its port specification.
Change one variable at a time
Do not replace the cable, dock, display mode and firmware simultaneously. Start with a direct connection and the supplied cable, then change only the cable, only the source, or only the adapter. Write down which combination produced power, a logo, a stable picture or a black screen. This simple log prevents a temporary recovery from being mistaken for a permanent fix.
When the host has no USB-C video output: choose an active adapter path
An HDMI or DisplayPort socket cannot drive USB-C display glasses with a passive charging dongle. The conversion requires a powered dock or adapter designed to accept HDMI/DisplayPort video and provide a USB-C glasses output.

Desktop PC or graphics card
Connect the graphics card’s HDMI or DisplayPort output to the dock’s video input. Connect the dock’s required USB power and data leads, then connect the glasses to the dock’s USB-C display output. Confirm that the graphics card is the selected display source and that the dock’s power indicator or equivalent status is normal.
Recommended Free Tools
Game console
Use an adapter specifically documented for the console’s HDMI output and for XR glasses. Provide the adapter’s USB power separately when required. A console USB port may not supply the power or data combination the dock expects, so follow the dock’s wiring diagram rather than assuming a single cable is sufficient.
Android phone without DP Alt Mode
If the phone’s USB-C port is charging/data-only, a passive cable cannot add native DisplayPort output. An active, powered conversion solution may work only when its documentation explicitly supports that phone and operating system. Check the exact phone model before buying; the presence of USB-C alone is not enough.
Adapter checklist
- Confirm that the input is HDMI or DisplayPort, whichever your source actually provides.
- Confirm that the output is intended for USB-C display glasses, not merely USB-C charging or a standard USB-C monitor.
- Verify the dock’s required USB power and data connections and whether its stated power guidance applies to your glasses model.
- Check supported resolution, refresh rate and HDR combinations across the source, dock and glasses.
- Use the dock’s specified cable on the glasses side; a generic charge-only USB-C lead can still leave the screen black.
- Read the current manual for firmware or companion-app requirements before purchasing.
There is no universal adapter that works with every Android XR product. Model-specific compatibility matters more than the number of sockets on the adapter or its advertised charging wattage.
Android Studio emulator pairing recovery
This branch applies to an Android XR emulator setup, not necessarily to retail glasses.
- Stop both the phone emulator and the glasses emulator.
- Cold-boot the phone emulator.
- Try the association again.
- If it still fails, stop the glasses emulator and wipe its data.
- In the phone emulator, open Settings > Connected devices.
- Select the glasses device and choose Forget.
- Start the emulators and pair them again as a new device.
Wiping emulator data removes its stored state, so use this only after a normal stop and cold boot have not restored pairing. The cold boot and the “Forget” action clear different parts of the association state; doing only one may leave the stale pairing in place.
What each symptom usually means
| Symptom | Most useful first checks |
|---|---|
| The glasses do not power on | Verify host or dock power, reseat the cable, test the supplied cable, and confirm that the dock itself has power. |
| A logo appears, then the image is black | Check DP Alt Mode or Thunderbolt support, replace the cable with a video-rated model, bypass hubs and adapters, and review external-display settings. |
| The phone charges the glasses but never detects a display | Confirm that the phone supports DisplayPort over USB-C; charging alone proves only that power negotiation works. |
| Wireless PC Connect cannot find the computer | Check Windows 10-or-newer compatibility, PC Connect installation on both devices, same-Wi-Fi membership and QR/PIN pairing. |
| An emulator repeatedly refuses to associate | Cold-boot the phone emulator; if needed, wipe the glasses emulator, forget it in Connected devices and pair again. |
Black screen after a successful connection
A successful USB connection does not guarantee a usable display mode. First remove any dock or hub and establish a direct signal. Then check whether the source is set to mirror or extend, whether the chosen resolution and refresh rate are supported by the glasses, and whether HDR or another optional mode is causing the failure. Make one change at a time so you can identify the setting that restores the picture.

If a logo appears briefly, the glasses are receiving at least some power and initialization data, but that does not confirm that all DisplayPort lanes negotiated correctly. Test a lower supported mode only if the model’s manual lists it, and return to the documented mode after the basic direct-connection test.
Intermittent picture or repeated reconnects
Intermittence usually points to a marginal cable, insufficient power, a loose connector or an adapter that cannot maintain the negotiated video mode. Test a shorter approved cable, direct connection and a separately powered dock. Avoid bending the cable sharply at either plug while testing.

How to compare two possible setups
When a direct USB-C path and an adapter path are both available, compare the properties that affect signal stability rather than choosing only by connector price.
| Comparison point | Direct USB-C connection | HDMI/DisplayPort dock connection |
|---|---|---|
| Host video capability | Requires USB-C DisplayPort Alternate Mode or Thunderbolt 4 | Uses HDMI or DisplayPort from the host and converts it to the glasses’ USB-C input |
| Power delivery | May draw power from the host; verify the model’s requirement | Usually needs the dock’s USB power connection in addition to the video cable |
| Extra hardware | No hub is preferred for diagnosis | A powered, XR-compatible dock or active adapter is required |
| Cable requirement | Full-featured USB-C cable rated for DisplayPort video | Appropriate HDMI or DisplayPort cable plus the dock’s specified USB-C cable |
| Resolution, refresh and HDR | Limited by the host port, cable, glasses and firmware | Limited by every stage: source, adapter, cables, glasses and firmware |
| Model-specific software | Host display settings and glasses firmware may matter | Dock firmware, glasses firmware and any required app may matter |
Before purchasing an accessory, check the current manual for the exact glasses model, phone or computer and adapter. A cable advertised only for charging is not a substitute for a DisplayPort-rated cable, and a passive USB-C gender changer is not an HDMI-to-USB-C video converter.

Manufacturers can diagnose a failed connection much faster when the test conditions are precise. Prepare:
- Exact glasses model and firmware version.
- Source device model and operating-system version.
- Whether the source port is documented for DisplayPort Alternate Mode or Thunderbolt 4.
- Every cable, hub, dock or adapter in the path, including its power connection.
- Whether the glasses power on, show a logo, display a black screen or remain completely dark.
- Display mode, resolution, refresh rate and HDR setting used during the test.
- Results from a second known-compatible source or cable.
XREAL’s support guidance specifically asks for source, operating-system, adapter-path and glasses information. Providing the same details for another manufacturer avoids a long sequence of basic questions.

Does a USB-C port always support video for XR glasses?
No. The port must explicitly support DisplayPort Alternate Mode, or provide a compatible Thunderbolt 4 video path. USB-C charging and data support alone cannot drive a display.
My phone charges the glasses, so why is the screen still black?
Charging proves that power negotiation works, not that DisplayPort video is available. Check the exact phone specification for DisplayPort over USB-C, then test the supplied or another full-featured video-rated cable.
What adapter do I need for a console or desktop with HDMI?
Use a powered HDMI/DisplayPort-to-USB-C dock or active adapter designed for XR glasses. Feed HDMI or DisplayPort video into the dock, connect every required USB power/data lead, and connect the glasses to its USB-C display output. A passive charging dongle is not sufficient.

Most connection failures become clear once you separate discovery, power and video. For wireless PC Connect, use Windows 10 or newer, install the software on both devices, keep them on the same Wi-Fi and complete the QR/PIN confirmation. For wired video, verify DP Alt Mode or Thunderbolt 4, use a full-featured cable, test directly without hubs and confirm the power path. If the source has only HDMI or DisplayPort, use a powered XR-compatible dock. Check the exact model manual before buying accessories, because Android XR glasses do not share one universal port, firmware or adapter specification.
