Modern multimedia capabilities make it possible to display content from a smartphone on a large TV screen, and a wireless network isn't always a requirement. Many users face situations where the router is temporarily unavailable, the Wi-Fi signal is weak, or they need to transfer confidential data without the risk of it being intercepted over the network. In such cases, it's important to know alternative methods that ensure stable video and audio transmission. Connecting via a physical interface or directly connecting devices allows access to photo galleries, video files, and even screen mirroring.
Technologies Samsung Smart View Standard data transfer protocols offer several ways to accomplish this. The method you choose depends on your smartphone model, Android or iOS operating system, and the availability of ports on your TV. In this article, we'll cover wired and wireless options that don't require a router, so you can choose the one that best suits your situation.
Using a cable is the most reliable way to transmit a high-definition signal without lag. If you can afford a small adapter or cable, you'll get image quality that often surpasses wireless alternatives. This method is especially useful for watching high-definition movies or showing presentations where image clarity is essential.
Using HDMI cable and adapters
A wired connection via HDMI provides the highest quality image without lag or compression artifacts. Modern Samsung smartphones, especially the flagship Galaxy S and Note series, support this technology. HDMI Alt Mode, which allows you to transmit a video signal directly through the USB-C port. To implement this method, you will need a special adapter, often called a USB-C to HDMI adapter or hub.
The connection process is quite simple and doesn't require any complicated software setup. Simply plug the HDMI connector into an available port on your TV and connect the USB-C connector to your smartphone. The TV will automatically recognize the new signal source, and all you need to do is select the appropriate input number (HDMI 1, HDMI 2, etc.) using the remote control.
⚠️ Attention: Not all budget smartphone models support video output via USB-C. Before purchasing an adapter, make sure your USB port supports the MHL or SlimPort standard, or check the official documentation for specific model specifications.
It's important to note that when using genuine Samsung adapters, DeX can activate automatically, transforming the phone's interface into a desktop-like experience. This significantly simplifies file navigation and launching apps on the larger screen. If the adapter has additional USB ports, you can simultaneously connect a keyboard or flash drive, expanding the system's functionality.
The quality of the transmitted image will depend on the capabilities of the cable and the version of the HDMI standard. For resolution 4K UHD It is recommended to use HDMI 2.0 or higher cables to ensure the refresh rate 60 Hz and HDR support. Older, standard cables may limit resolution to 1080p, which is also an acceptable result for most tasks.
Connection via USB port and storage devices
If you want to watch pre-downloaded movies, photos, or listen to music, using your TV's USB port is the simplest solution. In this case, your smartphone acts as an external drive, and the TV reads the media files directly. To do this, connect your phone to the TV using a USB cable (usually USB-A to USB-C or Micro-USB) and set your smartphone to file mode.
After a physical connection, a request for data access permission will appear on the phone screen. You need to select the mode MTP (Media Transfer Protocol) or "File Transfer" so the TV can see the contents of the device's internal memory or memory card. Without this step, the TV will only see the phone as a charging device.
- 🔌 Connect the USB cable to the port on your TV marked as

Please note that Samsung TVs' built-in media players may not support all video file formats. If a file doesn't play or plays without sound, the required codec may be missing. In this case, it's easier to copy the file to a FAT32 or NTFS-formatted flash drive and connect it directly.
☑️ Check before connecting USB
This method is ideal for watching heavy content, as it doesn't burden the phone's processor with decoding the video stream in real time. The TV handles this task for you, using its hardware resources. However, playback controls (such as rewinding and pausing) will be handled by the TV remote, not the smartphone interface.
Screen Mirroring and Miracast technology without a router
Wireless connection is possible even without an active internet access point, thanks to technology Wi-Fi DirectIn the Samsung ecosystem, this feature is often implemented through the Smart View app or the "Cast" feature in the standard Android settings. Unlike Chromecast, which requires a Wi-Fi network for syncing, Miracast creates a direct peer-to-peer connection between devices.
To activate this mode, ensure both devices are in close proximity to each other. On your Samsung TV, go to the signal sources menu and select "Connect to a mobile device" or "Screen Mirroring." The TV will then enter standby mode and begin searching for available devices.
⚠️ Attention: When using wireless screen mirroring, your smartphone's battery may drain significantly faster than usual. It's recommended to keep your phone connected to a charger during extended viewing sessions.
On your smartphone, open the quick settings panel and find the button Smart View or "Cast." The phone will begin searching for displays, and your TV should appear in the list. After selecting the device, a connection confirmation prompt may appear on the TV screen, which you'll need to accept using the remote.
Image quality with this connection may vary depending on interference in the air and the distance between devices. Since the connection is established directly, without a router, the data transfer speed is limited by the Wi-Fi capabilities of both devices. This is an excellent option for static images or presentations, but a slight input lag may be observed in fast-paced games.
Why does the image disappear during broadcasting?
Sometimes the connection may be interrupted due to congestion on the Wi-Fi channel from neighboring networks. In this case, try moving your phone closer to the TV or turning off Bluetooth on your smartphone, as it operates in the same frequency range and may cause interference.
Comparison of methods for connecting a smartphone to a TV
Choosing the optimal connection method depends on your specific needs: whether you need to share your screen in real time or simply play a video file. Each method has its own advantages and disadvantages, which should be considered before setting up.
| Method | Image quality | Latency | Necessary equipment |
|---|---|---|---|
| HDMI cable | Maximum (up to 4K HDR) | Absent | USB-C to HDMI adapter |
| USB drive | Depends on the file | No (local) | USB cable or flash drive |
| Smart View (Miracast) | High (compression) | Low/Medium | No (built-in Wi-Fi) |
| DLNA (via router) | High | No | Router (local area network) |
As the table shows, wired methods offer superior stability and quality, while wireless options offer convenience and the freedom from unnecessary wires. If you plan to display images frequently, it makes sense to invest in a high-quality docking station with HDMI output.
Setting up DLNA via a local network
Although this article focuses on connecting without Wi-Fi, it's worth mentioning a nuance: DLNA requires a router, but it doesn't require access to the wide area network (WAN). If you have a router, even without a cable connection from a provider, you can create a local network. In this case, the phone and TV will "see" each other via the protocol. DLNA/UPnP.
To use this method, both devices must be connected to the same Wi-Fi network (even if there's no internet access). Samsung TVs usually already have DLNA support built in, so simply launch the "Media" app or a similar one. On your smartphone, open a gallery app or video player that supports the "Broadcast" or "Cast" function.
Once you find your TV in the list of available devices, you can send the selected file to it. The TV will download it over the local network and begin playing. The advantage of this method is that the phone can be used for other tasks after playback starts, and the video will play smoothly since buffering occurs on the TV.
- 📡 Make sure your phone and TV are connected to the same Wi-Fi network.
- 📂 Open the video file on your smartphone.
- 📺 Click the "Broadcast" button (screen icon with an arrow).
- ✅ Select your TV from the list of devices.
This method is convenient because it doesn't require any additional accessories and allows you to use your phone as a remote control. However, it's not suitable for screen mirroring (duplicating the OS interface), as it only transfers the media file's contents.
Troubleshooting connection issues
Even if you follow the instructions correctly, technical difficulties may arise. Often, the problem lies in screen resolution settings or file formats. If your TV displays "Unsupported format," try changing the output resolution in your phone's settings (if available) or converting the video.
If Smart View doesn't find your TV, check if Client Isolation mode is enabled on your router if you're using a local network. This mode prevents devices from seeing each other. When connecting directly via Miracast, make sure your phone isn't in power-saving mode, which can disable Wi-Fi to conserve battery life.
⚠️ Attention: The Samsung TV menu interface may differ depending on the model year and Tizen operating system version. The layout of menu items may vary, so make sure the names are consistent.
If there's a picture but no sound, check the audio settings in the TV menu. Sometimes the default audio is on the mobile device, and you need to change it in the Bluetooth or media audio output settings. In some cases, simply rebooting both devices helps, clearing temporary network errors.
Additional features and operating modes
Modern Samsung TVs support a variety of usage scenarios. For example, the mode Art Mode It allows you to turn a turned-off TV into a painting, allowing you to stream your photos to the screen in high quality without constantly illuminating the screen. You can also use a USB drive or a direct connection for this.
Game Mode, which minimizes input lag, is essential for gamers. When connected via HDMI, this mode is often activated automatically. When connected wirelessly, lag can be critical for shooters, but is perfectly acceptable for turn-based strategy games or gameplay.
Don't forget about security: when connecting to other people's Wi-Fi networks (guest mode), use only wired connections or ensure that the file-sharing service on your phone is hidden from prying eyes. A direct cable connection eliminates any risk of data interception.
Is it possible to connect an iPhone to a Samsung TV without Wi-Fi?
Yes, but only via a wired Lightning to HDMI adapter (or USB-C to HDMI for newer models). Wireless AirPlay 2 technology on Samsung TVs requires a local Wi-Fi network for syncing, even when the internet is not used. Without a router, wirelessly connecting an iPhone to a Samsung TV is impossible.
Why doesn't the TV see the phone via USB?
Most often, the problem is with the connection mode. By default, the phone can only charge. Pull down the notification shade on your phone, tap the "USB Charging" notification, and select "File Transfer" or "MTP." Also, check the cable for damage.
Does Smart View require internet access?
No, internet access is not required. Smart View uses Wi-Fi Direct technology, which creates a direct connection between your phone and TV. A router is not required; the Wi-Fi modules on both devices must be working properly.
What's the best cable for connecting the Galaxy S23 to a TV?
An official Samsung USB-C to HDMI adapter or a certified HDMI 2.0-compliant alternative. This will ensure 4K signal transmission at 60 fps. Cheap cables may only support 30 Hz or lower resolutions.
