Transfer photos from your phone to a big TV screen DEXP Using Wi-Fi seems like a simple task until you encounter lags, connection errors, or missing features in the menu. Unlike brands like Samsung or LG, televisions DEXP often work on simplified versions Android TV or proprietary firmware, where standard protocols like Miracast may be disabled or hidden. This article will help you understand how your model supports wireless transmission, what settings you need to enable, and what to do if your phone doesn't detect your TV.
We will consider 5 proven methods — from built-in features to third-party apps — and we'll also address common issues: why the image is lagging, how to fix the "Device not supported" error, and what to do if Wi-Fi Direct refuses to turn on. We'll pay special attention to the following models: DEXP on Android 9/10 (for example, series H32D7000 or U50F6000), where the connection algorithm differs from newer versions.
If you have previously tried to transfer photos via Screen Mirroring and received the message "Connection failed," the problem most likely lies in protocol incompatibility or blocked ports by the router. Below you'll find step-by-step instructions that take these nuances into account, as well as alternative solutions for cases where standard methods don't work.
1. Checking the compatibility of your DEXP TV with wireless transmission
Before attempting to connect, please make sure your TV is DEXP Generally supports the required protocols. Most models after 2019 are equipped with at least one of the following standards:
- 📶 Wi-Fi Direct - direct phone-TV connection without a router (works on most models) DEXP with Android TV).
- 🖥️ Miracast - screen duplication according to the standard
Wi-Fi Display(may be calledScreen MirroringorWireless Display). - 📂 DLNA — a protocol for streaming media files (supported by applications like LocalCast or BubbleUPnP).
- 🔗 Google Cast - only on models with certified Android TV (eg DEXP H43D7100).
To check available options:
- Take the remote control and press the button
Home(orMenuon older models). - Go to
Settings → Network and Connections(orNetwork settings). - Look for points
Wi-Fi Direct,Screen MirroringorMiracast.
Attention! On TVs DEXP with firmware based on Linux (non-Android) wireless image transfer is often limited to only DLNA. Check your TV model - if there is a letter in the name L (For example, DEXP L32H7000), most likely it is a Linux version.
2. Method 1: Transfer via Wi-Fi Direct (direct connection)
This is the most reliable method for models DEXP on Android TV, as it doesn't require a router and works even without internet access. The instructions are suitable for phones with Android 6.0+ And iOS 13+ (with restrictions).
Step 1: Activate Wi-Fi Direct on your TV:
- Open
Settings → Network & Connections → Wi-Fi Direct. - Turn on the function and wait until the TV becomes “visible” to other devices.
- Remember the network name (usually
DIRECT-xx-DEXP[MODEL]).
Step 2. Connect your phone:
- 📱 Android: Open
Settings → Connections → Wi-Fi, find your TV's network and connect. No password required. - 🍎 iPhone: Wi-Fi Direct is not supported directly. Use an app. ApowerMirror or Screen Mirroring (see Method 4).
Step 3. Upload the image:
- 🖼️ On Android Open your gallery, select a photo, tap Share and choose an option
Wi-Fi DirectorSend to device. - 📺 A notification about an incoming file will appear on the TV - confirm receipt.
The TV is on and not in sleep mode
Wi-Fi Direct is activated in the TV settings.
Battery saving mode is disabled on the phone.
The distance between devices is no more than 5 meters-->
⚠️ Attention: On some models DEXP (For example, U43F6000) Wi-Fi Direct only works in "Access Point" mode, not "Client" mode. If your phone doesn't see your TV, try enabling the "Wi-Fi Direct" option on your TV. Create an access point in the Wi-Fi Direct menu.
3. Method 2: Screen Mirroring via Miracast
Miracast allows you to broadcast your phone's screen to TV in real time, but requires support from both devices. DEXP This function can be called Wireless Display, Screen Mirroring or Wi-Fi Display.
How to turn on on TV:
- Go to
Settings → Display → Wireless Display(orSettings → Devices → Screen Mirroring). - Activate the feature and wait for the “Ready to connect” message.
How to connect your phone:
- 📱 Android: Open
Settings → Connections → Screen Mirroring(orScreencasting), select yours DEXP from the list. - 🍎 iPhone: Use
Control Center → Screen Mirroring, but only if the TV supports it AirPlay (a rarity for DEXP).
Once connected, open your phone's gallery—the image will be mirrored on your TV. To cast a specific photo, simply open it in full-screen mode.
| Problem | Possible cause | Solution |
|---|---|---|
| The phone doesn't see the TV. | Miracast is disabled on the TV. | Check your settings Wireless Display on TV |
| The connection is broken | Weak Wi-Fi signal | Reduce the distance or reboot the router |
| The image is lagging | Low bandwidth | Switch the router to the range 5 GHz |
| No sound | Miracast only transmits video. | Use a separate audio output (Bluetooth or HDMI) |
4. Method 3: Transfer via DLNA (media server)
DLNA — a universal protocol for streaming media files over a local network. It works on most TVs. DEXP, but requires that both the phone and TV are connected to the same router.
Setting up on TV:
- Connect your TV to Wi-Fi (in
Settings → Network). - Make sure the function
DLNAorMedia serverincluded (usually inSettings → Network → Home Network).
Transfer from phone:
- 📱 Android: Install the application LocalCast or BubbleUPnP, open the gallery, select a photo and click "Send to" → select yours DEXP.
- 🍎 iPhone: Use VLC or nPlayer - they support DLNA.
If your TV does not appear in the list of devices, check:
- 🔌 Both devices are connected to the same Wi-Fi network.
- 🔄 The TV is in DLNA Visibility mode (sometimes called
Remote access). - 🛡️ The router's firewall doesn't block ports
1900/TCPAnd1901/UDP.
Why is DLNA slow?
DLNA transfer speed depends on your Wi-Fi network's bandwidth. If your router operates at a frequency 2.4 GHz and loaded on other devices, photos may load with a delay. Solution:
1. Switch the router to 5 GHz (if supported).
2. Disconnect other devices (smartphones, tablets) from the network.
3. In the router settings, enable the mode WMM (Wi-Fi Multimedia) to prioritize media traffic.
5. Method 4: Mirroring applications (ApowerMirror, LocalCast)
If built-in features don't work, third-party apps can help bypass restrictions. Let's look at two proven options:
1. ApowerMirror (for Android/iOS):
- 📲 Install the app on your phone and computer (if necessary) or use the TV version.
- 🔗 Connect both devices to the same Wi-Fi network.
- 🖥️ Open a browser on your TV and go to the address shown by the app on your phone.
- 📷 You can now broadcast your screen or send individual photos.
2. LocalCast (Android only):
- 📱 Install LocalCast from Google Play.
- 📺 Turn on TV mode
DLNAorMiracast. - 🖼️ In the app, select a photo, click "Send to" and choose yours DEXP.
⚠️ Attention: When using ApowerMirror on iPhone connection via will be required AirPlay, which most TVs have DEXP is not supported. In this case, use Lightning-to-HDMI cable or Apple TV as an intermediary.
6. Method 5: Cloud services (Google Photos, Dropbox)
If wireless protocols fail, cloud services are a universal solution. The downside is that they require internet access and a service account.
Instructions for Google Photos:
- Upload your photo to Google Photos from the phone.
- On your TV, open the app Google Photos (if it is not there, install it via Play Market on Android TV).
- Log in with the same account and find the downloaded image.
Alternative services:
- 📁 Dropbox/OneDrive: Upload the photo to the cloud, then open the corresponding app on your TV.
- 📧 Email: Send the photo to yourself by email, then open the email client on your TV.
Important: On DEXP TVs running Android 8.0 or later, the Google Photos app may not support automatic syncing. In this case, use the TV browser to access the web version of the service (photos.google.com).
