FAQs & Troubleshooting
Wireless Mirroring
Cannot search for projector model when mirroring iOS device
1. First, please ensure that your iOS device and the projector are connected to the same WiFi network. If they're already on the same network but still not discoverable, it's recommended to reset the projector to its factory settings, restart it, and then try reconnecting.
2. Check if the router is placed too far from the projector (ideally, it should be in the same room), or temporarily enable your phone's mobile hotspot feature so the projector can connect to the phone's hotspot before attempting screen sharing again.
3. Confirm whether the current WiFi is set to guest mode; usually, a guest WiFi network name will include a "Guest" suffix. If so, switch to the main network and retry.
4. Try using a wired screen mirroring connection or connecting directly to the projector's hotspot to see if you can successfully establish a connection.
The device can search for the projector but cannot connect to it
1. Please try restarting both your device and the projector, then re-attempt the connection process.
2. If you are using an Android phone such as a Google or Motorola model, there may be compatibility issues preventing screen mirroring. However, most Samsung phones are compatible; still, some newer models might not support this feature. Please verify your phone's model.
3. Check whether your current network condition is stable. If the network is poor, consider trying a wired connection or, keeping the WiFi switch on, turn off the WiFi network on your projector, then within the screen-mirroring interface, search for and connect to the projector's WiFi hotspot following the prompts. Alternatively, you can also achieve screen mirroring by having the projector connect to your phone's mobile hotspot.
iOS device freezes or drops when mirroring
2. If you are experiencing poor network conditions, consider using a wired connection or, while keeping the WiFi switch on for the projector, temporarily disconnect it from the Wi-Fi network. Next, proceed to the projector's screen mirroring interface and follow the on-screen prompts to connect your device to the projector's own WiFi hotspot. Then, try to perform screen mirroring again.
3. In case the projector experiences lagging after an update, we need to know your current software version to analyze the issue. We will provide you with a new software update to address this problem.
Black screen when mirroring on mobile phone
2. Ensure that you've selected the correct screen mirroring mode. For instance, if you're using a Samsung phone, make sure you've chosen the "Smart View" option for proper connection.
3. If after adjusting the 4D keystone correction, you encounter a black screen and cannot display the content, it's recommended to restore your projector to its factory settings and avoid adjusting the 4D keystone settings during screen mirroring. This way, try establishing the screen mirroring to see if it displays correctly.
Black screen when mirroring computer
1. In order to realize the same screen between Win computers, you need to press Win+P keys to select copy or extend mode for settings.
2. Before starting the same screen, please adjust the projector to obtain the ideal picture effect, and avoid 4D adjustment and keystone correction during use.
3. If your system is Win10, we recommend it. If it is not a Win10 system, there may be compatibility issues. It is recommended that you give priority to using HDMI connection to ensure stability and compatibility.
Black screen when mirroring Samsung device
2. If, after performing the above steps, the Samsung device still fails to project properly, there may be compatibility issues between your specific model and our projector. Please provide us with the exact model number of your device, so we can record and forward it to our factory for further investigation and to devise potential optimization solutions.
When playing a video on the same screen, there is picture but no sound or there is sound but no picture.
In a scenario where the screen mirrors successfully but only the audio is heard from the projector while the visual output remains black, this issue is most probably caused by device compatibility problems.
WiFi&Bluetooth Connection
The projector cannot find WiFi
1. Please turn off and then re-enable the WiFi feature to see if it can search for networks normally.
2. If the issue persists, attempt a factory reset on your device and then check within the WiFi settings to see if it can search for networks correctly. If neither of these actions resolves the problem, it could indicate a fault with the WiFi module itself, in which case we recommend replacing the relevant module.
Can search for WiFi but cannot connect to it
1. Please check the network signal strength indicator first to ensure that the network signal is normal.
2. If the network connection is abnormal, you can try restarting the router or using your smartphone's 4G or higher mobile data to create a hotspot for the projector to connect. This approach helps identify if the issue lies with the router.
3. If prompted with a password error, please verify that the entered password is correct (you may enable the password display function for this). If the password has been confirmed to be accurate but still fails to connect, you can attempt to set up a simple WiFi hotspot password using your phone and have the projector connect to it, thus testing the device's connectivity capabilities.
4. If all of the above steps prove ineffective, we recommend that you reset the projector to its factory settings and then try connecting again.
WiFi does not connect back
2. Regarding the second scenario, since disassembly of the unit is required, this issue cannot be resolved remotely. However, if you are willing to perform a self-disassembly check, we can provide you with detailed step-by-step video guidance for disassembling the device and assisting you in organizing the internal wiring.
The projector cannot search for the Bluetooth speaker or cannot connect to it
2. Subsequently, check whether it can successfully search for and connect to other Bluetooth speakers. If it can pair normally with other devices, this may indicate a compatibility issue between your speaker and the projector.
3. Note that the effective range of Bluetooth connections is limited; ensure that the distance between the projector and the speaker does not exceed 10 meters in an open environment. If there are obstacles (such as walls) between them, maintain a distance of within 5 meters.
4. We recognize that Bluetooth connectivity has two modes: receiving mode, which can only connect to Bluetooth speakers or headphones; and transmitting mode, which can be detected by playback devices like smartphones. Based on your description, we suggest verifying the current Bluetooth working mode of your projector and ensuring the correct operation steps, referring to the product manual for accurate guidance.
If the above troubleshooting steps do not resolve the issue, kindly provide us with the Bluetooth version information and specific brand and model of both your projector and speaker. We will promptly conduct testing and validation to assist you with resolving the Bluetooth connection problem.
The Bluetooth speaker connection is unstable or the sound is delayed
1. To ensure a stable Bluetooth connection, it is recommended that you place the projector and Bluetooth speaker in close proximity to each other.
2. In order to prevent mutual interference, please do not place the projector and Bluetooth speaker alongside high-power electrical appliances.
3. To minimize data transmission latency, it is advised to connect the Bluetooth speaker first, followed by connecting your playback device to the projector.
When connected to a Bluetooth headset, one has sound and the other has no sound.
USB Disk/HDMI/AV Connection
No display when plugging in the USB flash drive
1. Please first confirm whether your USB drive can be read normally on other devices. Additionally, you can try connecting your phone to the projector with a USB cable for charging purposes, to verify if the projector's USB interface is functioning correctly. If there are two USB ports available, please attempt using the other one. If both fail to work properly, it may be necessary to consider replacing the projector.
2. Do you happen to know the specific format of your USB drive? Some projectors have limitations regarding compatible USB drive formats. If the current format is not supported, please try changing the format of the USB drive. Should you need guidance, I can provide you with a detailed step-by-step instruction link so that you can perform the operation yourself.
When plugging in the USB flash drive, there is a display but cannot be opened.
FAT32 formatted USB drives or external hard drives have a maximum capacity of 192GB, with a single file size limit not exceeding 4GB. On the other hand, NTFS formatted devices can support capacities up to 2TB and individual files can also reach 2TB in size. Regarding SD cards, the SD2.0 and SDHC versions have an upper limit of 32GB, while the SDXC version can extend up to 1TB.
Please note that for both USB drives and SD cards, there is a limit of 200 files per root directory or subdirectory. If this limit is exceeded, you will need to create additional subdirectories for storing your files.
To convert the format of a USB drive, you can download and use a specialized format conversion software. If your current USB drive's format does not support large capacities or large file storage, it is recommended to perform a format conversion or consider upgrading to a larger capacity USB product that better suits your needs.
The projector shows no signal or weak signal
2. Check whether the connection interface matches the selected signal source correctly. Attempt switching between different signal sources to see if an image appears, thus eliminating the possibility of incorrect signal source or interface selection.
3. Replace the cables or try connecting the device to another unit to verify whether the issue lies with the cable or the device itself.
4. Connect this device to another display device for testing playback. If it still fails to play normally, it could indicate that the device does not have signal output capability (projectors typically only receive input signals and do not support video signal output).
If none of these steps resolve the problem, it's likely that there might be a fault with the projector's interface, at which point considering a replacement of the projector would be necessary.
The screen flickers or there is no screen and only sound
2. Please check whether the cable connections are secure, or consider replacing the cables to test if normal functioning is restored.
3. Ensure that the video resolution outputted by your playback device falls within the projector's supported range (with a maximum of 1080p/60hz). Exceeding this resolution may lead to video unplayability or screen flickering. Adjust the resolution to an appropriate level and try again.
The screen is not fully displayed
In the display settings, you can adjust the aspect ratio to cater to your actual requirements and select the most suitable display ratio.

If you encounter a situation where playback is not possible, please first attempt to connect the signal source to a television to see if it can display properly. If the television also fails to play the content, there may be an issue with the signal conversion.
Additionally, you can directly test the projector by connecting it to devices such as a computer or DVD player that do not require conversion. Should the projector still fail to connect after these steps, it is highly likely that there is a problem with the projector's interface.
File Play
Picture cannot be opened
The resolution of your image may be too large, and make sure the image file size does not exceed 6.8M. This ensures the best results for image uploading and display.
Video play abnormality
1. If your projector is unable to play a video, it will typically display an error message. Please transcode the video into a format that is supported by the projector. You can find specific details on supported formats in the product specifications manual. For guidance on how to transcode the video, you can search for relevant tutorials on internet search engines like Google.
2. Please check the resolution of your video file to ensure that it falls within the range supported by the projector. Generally speaking, videos with resolutions up to 1080P/60Hz should be playable without issues. However, if the video is in 4K or has a frame rate higher than 60Hz, and your projector does not currently support such high decoding and playback capabilities, then playback problems may arise.
Audio play abnormality
If it does not, we recommend you search on Google for a solution yourself. Simply type in "how to convert audio formats" to find relevant tutorials.
Unable to open or display the document or file
2. On the projector, select the corresponding file format option or directly browse all files for viewing.
Projection Image
Black spots or bright spots on the projection screen
For dust on the viewfinder or display screen, you can dismantle the bottom cover and clean it using cotton swabs from the dust removal kit. As for dust inside the lens, it is recommended to gently tap the lens in the hope that the dust will naturally fall off. However, please note that you need to handle the device with caution during the operation to avoid causing any damage to it.
Foreign objects on the projection screen
First, determine whether the foreign object is located on the display screen and the Fresnel lens or on the lens itself. If it's situated on the display screen and the Fresnel lens, you can use a specialized dust removal tool for cleaning. If the foreign object is found on the lens, it's suggested that you try gently tapping the camera body to dislodge the debris.

Screen light leakage
Such circumstances typically present a greater challenge to rectify. Should the issue of light leakage be causing substantial impairment to your usage experience, we advise opting for a replacement unit with a new device.
The projection screen shakes
The whole picture is blurry
2. Upon startup, inspect the display interface for any visible damage to determine whether the Fresnel lens or the display screen has been compromised. After turning off the device, check if the lens has any scratches or signs of wear. In either of these scenarios, the product would only be eligible for return processing.
3. Have you been using the projector in an environment with significant temperature fluctuations? If there is condensation on the lens, you can use a hairdryer to gently heat and remove it. If this does not resolve the issue and there is suspected moisture affecting the display screen circuitry, we recommend running the projector for half an hour to see if it recovers. If the problem persists, we will provide you with a replacement service.
Blurred around edges
2. Regarding the projection display, you may have noticed that the light intensity and clarity at the edges are relatively weaker compared to the center area. This is a common phenomenon in the current projector industry. We are continuously striving to enhance product performance, but currently, such an occurrence is considered standard across various brands. Please understand this aspect.
One edge is blurred
2. If your projector is equipped with keystone correction functionality, when making substantial angle adjustments, it may result in blurriness on one side of the image.
Auto focus blur
2. In case the lens focusing is restricted, you could try restoring the factory settings, or have a professional disassemble the unit to adjust the lens limit switch in order to remove the restriction.
3. The automatic focus might exhibit slight differences compared to what the human eye perceives. If the auto-focus result does not meet your clarity requirements, it is recommended to manually fine-tune for an ideal image quality.
Picture black and white
2. If you're unsure how to proceed or wish for a quick resolution, you can directly opt for restoring the factory settings.
Remote Control
The remote control is completely malfunctioning
1. Please try replacing the batteries with new ones.
2. If the issue persists, test the projector using a different remote control.
3. Ensure that the remote control is pointed directly towards either the front or back infrared receiver of the projector (with an effective distance of approximately 1 meter), and verify if all key functions are working properly. If it's determined that the projector's infrared receiver is faulty, you may need to request a replacement.
4. It's important to note that when using an infrared remote control, it should be aimed at the infrared receiving hole on the projector, ensuring there is no obstruction between the two.

2. Please replace the remote control with fresh batteries.
Others
Lens knob loose
1. Please check if the knob is at a normal tightness level by adjusting it to the middle position and then tilting the projector on its side while gently tapping the body. Observe if there's any displacement of the knob. If there's no movement, it indicates that the knob is in normal condition. However, if there's displacement, it suggests that the knob is too loose and requires replacement.
2. If the knob is too tight to turn, it may be jammed by foreign objects. Firstly, please inspect the surface for any visible obstructions. If no apparent foreign objects are seen, it could indicate an issue with the internal structure. In the event that this affects normal usage, it is recommended to replace the knob promptly.
Lens stuck
1. If you encounter a situation where the device is stuck and unable to move, you can try holding down the F+ or F- key to resolve the freezing issue.
2. If the lens cannot move in a certain direction, try holding down the opposite direction. The operation steps are the same as Method 1. Friendly reminder: When using electric focus, please avoid adjusting the lens to its extreme position; timely adjustments to the focus direction and projection distance should be made.
Lens cap problem
2. To ensure the lens cap operates smoothly and remains securely closed, kindly retract the lens before closing the lens cap.
Abnormal noise inside when shaking
Internal abnormal noise during operation
1. If the fan bearing failure has been confirmed, replacement is the only option.
2. Should the fan come into contact with any cable harnesses, please consider disassembling the unit for inspection and handle the situation accordingly based on the specific circumstances.
Projector won't turn on
2. If the red indicator light illuminates properly, but the projector fails to respond when the power button on the remote control or the body of the projector is pressed, it is likely a motherboard failure, requiring a motherboard replacement.
3. If the projector turns on momentarily and lights up, but then automatically shuts down, this could be due to abnormal temperature control protection or a software issue preventing startup.
4. When the projector powers on and the indicator light displays green as normal, yet no image is projected, it is most probable that the LED lamp has failed, necessitating the replacement of the LED lamp assembly.
The main interface is not displayed after booting
2. If during startup, the indicator light functions as expected but the projected image displays anomalies such as a blue screen or white screen, this might indicate a software issue. We recommend attempting a software upgrade to see if normal display can be restored.
