Modern technologies make it possible to transform the living room into a true multimedia center, where content from a smartphone instantly appears on the big screen. Screencasting (Screen Mirroring) has become the de facto standard for displaying photos, watching movies, and even mobile gaming. Device owners Samsung are in an advantageous position as the South Korean giant has implemented a variety of wireless protocols into its Smart TVs.
The basic principle of operation is to use a local network Wi-Fi, which transmits video and audio with minimal latency. You won't need additional HDMI cables or complicated adapters if both devices are on the same network. However, despite its apparent simplicity, the setup process may vary depending on your mobile device's operating system. Android or iOS.
In this article, we'll cover all connection methods in detail, from built-in features to third-party apps. You'll learn how to set up Smart View on Android, how to use AirPlay 2 on an iPhone, as well as what to do if the TV doesn't detect the phone. We'll cover technical nuances that are often overlooked during initial setup.
Preparing equipment and a Wi-Fi network
Before you begin setting up, make sure your TV is Samsung Connected to a Wi-Fi network. This is critical, as video streaming requires a stable connection. If the TV is connected via a LAN cable and the phone via Wi-Fi, streaming will still work in most cases, but it's best to use a single wireless network to minimize protocol conflicts.

⚠️ Attention: Some routers have an AP Isolation feature. When enabled, devices on the same Wi-Fi network won't be able to see each other, preventing video output.
You should also consider the bandwidth of your internet connection within your local network. While internet access isn't always necessary for image transmission (a local network is sufficient), the TV's Wi-Fi module may have limited speed. If you plan to stream 4K video, ensure your Wi-Fi signal is strong and stable.

Troubleshooting connection and latency issues
Despite the well-established protocols, users may encounter problems: the image flickers, the sound lags, or the phone doesn't detect the TV at all. First, try rebooting the router. Often, the problem stems from a router buffer overflow or an IP address conflict.
If you notice audio and video out of sync, try lowering the streaming resolution in your phone's settings or moving the device closer to the router. It's also worth checking if there are any background downloads running on other devices on the network that could be consuming bandwidth.

Frequently Asked Questions (FAQ)
Is it possible to display a screen without the Internet, only via Wi-Fi?
Yes, Screen Mirroring doesn't require internet access. It only requires a router to create a local Wi-Fi network to which both the phone and TV are connected. Some TV models can create a Wi-Fi Direct hotspot, which the phone can connect to directly without a router.
Why is the quality worse when streaming from YouTube than on the phone itself?
This may be due to a bitrate limitation during wireless transmission or router settings. Try using the built-in Cast function within the YouTube app (the TV icon in the corner of the video) rather than mirroring the entire screen. This will send a link to the TV, and the TV will automatically download the video in maximum quality.
Does my old Samsung TV support wireless streaming?
Almost all Samsung Smart TVs released after 2015 support Screen Mirroring (Miracast). Older models may not have built-in Wi-Fi or may only support a wired connection.
How do I mute my phone so it only plays on the TV?
When using AirPlay 2 on an iPhone, audio automatically switches to the TV. On Android, the Smart View menu often has a volume control button (a speaker icon) that allows you to select the audio output device. If you don't see this button, simply turn the volume down on your phone.
