Modern smartphones have become powerful multimedia centers, but watching videos on a small screen isn't always convenient. The owner of a popular model Samsung Galaxy A50 I often find myself wanting to stream YouTube content to a big-screen TV. Fortunately, wireless technology makes this possible quickly and without unnecessary wires, using only my home Wi-Fi network.
The process of synchronizing devices may seem complicated only at first glance. In fact, the operating system Android and the YouTube platform have built-in mechanisms for detecting and connecting to compatible displays. You don't need to buy expensive adapters or HDMI cables if both devices are on the same network.
In this article, we will take a detailed look at all the available ways to connect your Samsung A50 to your TV. We'll cover the built-in streaming features, how to use the YouTube app, and possible alternatives for older TV models. Proper setup will allow you to enjoy high-definition movies on the full screen.
Preparing equipment and a Wi-Fi network
The first and most important condition for successful synchronization is that both devices are located on the same local network. Your router It should distribute a signal that connects both your smartphone and TV. If your router operates in two bands (2.4 GHz and 5 GHz), make sure the devices are connected to the same frequency, although modern routers often combine them into a single network.
Check the operating system version on your phone. For Samsung Galaxy A50 Android updates are currently available to ensure stable operation of data transfer protocols. Go to Settings and check for updates, as older software versions may contain bugs that prevent the TV from being detected.
You should also make sure that the Smart TV function or built-in Wi-Fi module is enabled on your TV. Some models require manual activation of the signal reception mode in the network menu. Without an active internet connection on both devices, the function broadcasts it won't work.
Signal stability is critical. If the router is located far away or behind thick walls, image quality may suffer. Ideally, the distance between the access point and receivers should be minimal to ensure a high-quality data stream.

The easiest way to mirror your screen is by using technology Smart View, developed by Samsung. This feature is built into the One UI interface and allows you to mirror your smartphone's content to any compatible TV that supports the Miracast protocol.
To activate, swipe down from the top of the screen to open the Quick Settings panel. Find the icon Smart View and tap it. Your phone will begin searching for available devices within Wi-Fi range. When your TV's name appears in the list, tap it to start connecting.
After pairing, the image from the screen Samsung A50 The entire device will be copied to the TV. You can launch the YouTube app, and the video will play on the big screen. In this mode, the phone won't lock, and you can use it for other tasks, although the battery will drain faster.
Stream quality depends on your processor and network speed. If you notice audio and video out of sync, try closing background apps on your phone. This will free up system resources for a smoother video stream.
Stream directly through the YouTube app
The best option for watching videos is to use the built-in Casts feature in the YouTube app. This method doesn't mirror the entire smartphone screen, but forces the TV to download videos from the internet, saving battery life. smartphone and reduces the load on the processor.

Setting up the Samsung Galaxy A50 for AirPlay 2
If your TV supports the technology AirPlay 2 (often found in newer Samsung, LG, and Sony models), you can use it to stream content from an iPhone, but Android smartphones can also work with these protocols through third-party apps or built-in features.

⚠️ Note: When using screen mirroring via AirPlay or Miracast, audio may default to your phone's speaker. Be sure to switch the audio output to the TV in the Bluetooth settings or media control panel.
AirPlay 2 connection stability is generally higher than that of standard Miracast, as this protocol is better suited for video streaming. However, it can be more demanding on the local Wi-Fi network speed.
Using Google Chromecast technology
Many modern TVs have built-in support. ChromecastThis is a Google technology that is perfectly integrated with the Android operating system installed on Samsung A50. It allows you to stream content from a variety of apps, not just YouTube.
For this feature to work, make sure you have the app installed and updated on your phone. Google HomeIt helps manage smart home devices and configure device groups. It can also be used to mirror your smartphone's screen to your TV.

Solution and compatibility table
Despite the ease of setup, users may encounter various technical difficulties. Most often, issues are related to incompatible software versions or network security settings. Below is a table to help diagnose the problem.
| Problem | Possible cause | Solution |
|---|---|---|
| TV not found | Different Wi-Fi networks | Check the network SSID on both devices. |
| The video is lagging | Slow Wi-Fi speed | Move the router closer or reduce the video quality |
| No sound | Incorrect audio output | Select TV as a playback device |
| Black screen | HDCP protection | Use the official YouTube app |
If the TV and phone are on different subnets (for example, a guest network and the main network), they won't see each other. Some routers isolate wireless clients from each other by default for security reasons.
To troubleshoot the issue, try rebooting your router. This will clear the DNS cache and update the routing tables, which often helps devices "see" each other on the local network again. Disabling and re-enabling the Wi-Fi module on your smartphone also helps.
In some cases, antivirus software or a firewall on your router may block ports required for DLNA or Cast protocols. Check the security settings of your network equipment.
Alternative connection methods
If your wireless connection is unstable or your TV does not support Smart features, you can use wired methods. For For the Samsung Galaxy A50 with a USB Type-C connector, there are special HDMI adapters (MHL or DisplayPort Alt Mode).
A cable connection provides the highest image quality without compression or latency. This is ideal for watching high-bitrate videos or gaming, where every millisecond of response is crucial. However, this method is less portable and requires a free HDMI port on the TV.
Another option is to use media players such as Android TV Box or set-top boxes with AirPlay/Miracast support. They connect to any TV with HDMI and create a bridge between the smartphone and the screen, often offering more stability than built-in Smart TV systems.
⚠️ Important: When purchasing a USB-C to HDMI adapter, make sure it supports video. Many cheap cables are designed only for charging and data transfer, but do not transmit video.
Using external players also allows you to bypass the limitations of older TV operating systems. They receive regular updates and support all modern codecs and video formats available on YouTube.
