Video transfer from Samsung Galaxy on the big TV screen through Wi-Fi — a problem faced by millions of users. It's not always convenient to connect cables or use adapters, especially when both devices support wireless technologies. However, not everyone knows that there is at least 5 different ways to organize such a broadcast - from built-in functions Samsung Smart View to universal protocols like DLNA or Miracast.
The main problem is to figure out which method is suitable for your specific phone and TV model. For example, old Samsung TV series J (2015–2017) may not support Miracast, but they work great with DLNA, while the new ones QLED Between 2023 and 2026, all options are being offered at once. In this article, we will examine each method in detail, taking into account device compatibility, transmission speeds And picture quality, and we will also provide checklists for quick setup.
We will pay special attention to typical mistakes: why a video can brake, interrupt or not be transmitted to TV at all. Spoiler: in 80% of cases, the problem lies not in the phone settings, but in router or TV firmwareBut first things first.
1. Smart View – Samsung's signature feature
Samsung Smart View — is a proprietary technology (developed specifically for the ecosystem) Samsung), which allows you to broadcast your phone's screen to TV without delays. It works on the basis of the protocol Miracast, but with additional features like controlling TV from your phone or transmitting high-quality sound.
To take advantage Smart View, your phone should not be older than Galaxy S8 (2017) or Note 8, and the TV must support the function Screen Mirroring (usually these are models Samsung Smart TV 2016 and newer). If you have Galaxy A-series (For example, A52 or A73), check the availability of the function in the menu Settings → Connections → Smart View.
- 📱 On the phone: Swipe down to open the notification panel → tap the icon
Smart View(or go toSettings → Connections → Smart View). - 📺 On TV: Open
Settings → General → External devices → Screen Mirroring(on newer models the path may differ:Settings → All settings → Connection and sharing → Screen mirroring). - 🔗 Connection: Select your TV from the list of available devices on your phone. If prompted for a PIN, enter it on the TV screen.
Important: Smart View supports streaming in up to 4K resolution, but only if both devices are connected to the same 5 GHz Wi-Fi network. On 2.4 GHz, the maximum quality is 1080p, with possible lag.
The phone and TV are connected to the same Wi-Fi network. Screen Mirroring is enabled on the TV. Power saving mode is disabled on the phone. The distance between the devices is no more than 5 meters.
2. Miracast is a universal protocol for all TVs
Miracast - is a wireless image transmission standard that works on most modern TVs (not only Samsung). Unlike Smart View, it is not tied to a brand, but requires support from both devices. For example, Galaxy S21 and newer ones work great with Miracast, but the old models seem to be Galaxy J5 (2016) may not support it.
The main advantage Miracast - no dependence on a Wi-Fi router: devices are connected directly (using Wi-Fi technology) Wi-Fi Direct). This means that even if the internet goes down, the stream will continue. However, there are some downsides: audio delays (up to 200 ms) and reduced quality are possible with a weak signal.
- 📱 On the phone: Open
Settings → Connections → Advanced → Wireless Display(on some models the path is:Settings → Display → Transmit to TV). - 📺 On TV: Activate
Miracaston the menuSettings → Network → Screen Mirroring(orWi-Fi Direct). - ⚡ Clue: If the TV does not find the phone, restart both devices and try searching again.
⚠️ Attention: Some TVs Samsung 2018–2019 (for example, series NU7100) require a firmware update to work correctly withMiracastCheck the software in the menu for updates.Settings → Support → Software Update.

| Problem | Possible cause | Solution |
|---|---|---|
| TV is not in the list of devices | Disabled Screen Mirroring on TV |

| The video is slow or choppy. | Weak Wi-Fi signal (2.4 GHz) | Switch to 5 GHz or move the router closer |
| No sound during broadcast | The TV does not support the audio codec. | Try another method (eg. DLNA instead of Miracast) |
| Black screen on TV | Incompatible screen resolutions | Set the resolution to 1080p in your phone's display settings. |
Router tip: If the video is constantly freezing, check your settings. QoS (Quality of Service) in the router control panel. Prioritize traffic for devices. Samsung or disable speed limitation for the local network.
