Modern smartphones offer powerful multimedia capabilities, but the mobile device's screen is often too small for comfortable viewing of movies or photos with the whole family. It's natural to want to display content on a larger screen, but owners of TVs produced before the era of mass distribution Smart TV, face technical limitations. The lack of a built-in Wi-Fi module and operating system makes direct connection to a home network impossible.
Fortunately, engineers have come up with several workarounds that allow you to transform a regular screen into a multimedia center. Streaming content is possible even on models released 10-15 years ago, with the right adapters or software bundles. The key factor here isn't the age of the TV, but its availability of a video input. HDMI or composite connector "tulip".
In this article, we'll take a detailed look at all available methods, from wireless standards to using specialized gadgets. You'll learn how to set up Miracast or DLNA, and what budget solutions will allow you to stream videos from YouTube or Netflix without buying a new TV.
Hardware Solutions: Turning Any TV into a Smart TV
The most reliable and high-quality way to broadcast images is to use external signal receivers. Older TVs don't have their own processor to handle internet traffic, so this function is handled by an external device connected via the video input. The most popular interface for this purpose is HDMI, which transmits a high-quality digital signal.
If your TV has an HDMI port, you'll need to purchase a dedicated media player or streaming stick. These devices connect to the Wi-Fi router automatically, creating a bridge between the internet and the screen. Your smartphone, in this case, simply acts as a remote control, sending playback commands.
There are several types of devices that solve the problem of missing smart features. The choice of a specific gadget depends on your phone's operating system and desired functionality.
- 📺 Google Chromecast — a compact flash drive that works perfectly with Android and iOS, allowing you to stream browser tabs and application content.
- 🍎 Apple TV — a full-fledged set-top box for the Apple ecosystem, providing stable AirPlay operation and access to iTunes.
- 🎮 Android TV Box — universal Android-based set-top boxes that turn your TV into a powerful computer with the ability to install apps.
It's important to note that most of these devices require power from a USB port or wall outlet. If your TV doesn't have a USB port with sufficient current, you'll need to use an additional power adapter, which is usually included.
Using Miracast for screen mirroring
Technology Miracast (often labeled as Screen Mirroring or Wireless Display) allows you to stream your smartphone's screen to your TV in real time. Unlike DLNA, which works with files, Miracast broadcasts exactly what's on your phone's display, including games and app interfaces.
To implement this method on an older TV, you'll need an adapter that supports this protocol. This could be a dedicated Wi-Fi receiver (dongle) or an Android set-top box. After connecting the device to the HDMI port, you'll need to switch the signal source on the TV by pressing the [Power] button. Source or Input on the remote control.
☑️ Setting up Miracast
The setup process on your smartphone typically takes less than a minute. In Android, this feature may be called differently depending on the manufacturer: "Wireless Projector," "Smart View" (Samsung), or "Cast" (Xiaomi). Once activated, your phone will begin searching for available devices within Wi-Fi Direct range.
Attention: ⚠️ When using Miracast, the phone and adapter must be in line of sight or at a minimum distance, as the signal is transmitted directly, bypassing the router, which can reduce the range.
Image quality depends on the phone's Wi-Fi module's power and the airwaves' congestion. Some lag is possible when controlling the device, making it less than ideal for fast-paced shooters, but perfectly acceptable for watching videos and presentations.
Why might the picture be twitching?
Delays when streaming via Miracast are often caused by signal interference from nearby routers or microwave ovens operating at 2.4 GHz. Switching the router to 5 GHz (if the adapter supports it) solves the problem.
Stream media via DLNA and UPnP
If your goal is to watch pre-downloaded movies, TV series or listen to music, then the technology DLNA (Digital Living Network Alliance) is the optimal solution. It doesn't require screen mirroring; it simply streams media from your phone to your TV's decoder (or set-top box), saving your smartphone's battery.
For DLNA to work, your old TV must support this feature (models marked DLNA Certified) or be connected to a set-top box (such as an Xbox, PlayStation, or Android Box) that can receive DLNA signals. The phone and receiving device must be on the same local Wi-Fi network.
Popular controller apps such as BubbleUPnP, VLC for Android or the standard Xiaomi Mi Video player, automatically scan the network. Once a compatible renderer (TV or set-top box) is detected, the app allows you to select a file and play it.
The main advantage of this method is that once playback starts, the phone can be used for other tasks or even locked—the movie will continue playing on the big screen. This is a distinct advantage of DLNA over screen mirroring.
It's worth noting that codec support depends on the capabilities of the TV or set-top box. If the file is in an uncommon format, the built-in player may not be able to open it, while third-party apps on an Android set-top box can easily handle the task.
Wireless HDMI Adapters: Choosing a Device
The market offers a variety of wireless HDMI adapters that let you connect an old TV to a Wi-Fi network. These devices resemble flash drives and are hidden behind the TV. They create their own access point or connect to your router.
When choosing an adapter, it's important to pay attention to the supported resolution. For older TV models with a matrix 720p or 1080p There's no need to overpay for 4K support, although a little extra security is a plus. Support for the standard is also important. HDCP 2.2, if you plan to stream content from secure platforms.
| Device type | Smartphone OS | Difficulty of setup | Picture quality |
|---|---|---|---|
| Google Chromecast | Android / iOS | Low | High |
| MiraScreen / AnyCast | Android / Windows | Average | Average |
| Apple TV | iOS / macOS | Low | Maximum |
| Android Box | All (via apps) | High | High |
Budget Chinese adapters (often sold under the names MiraScreen and EzCast) create their own Wi-Fi network. The phone connects to this network, and the image is streamed directly. This is convenient if the router is located far from the TV.
Software methods for TVs with USB and LAN
Some older TV models, although not formally Smart TVs, have a port LAN (Ethernet) and basic support for network protocols. In rare cases, if the TV allows apps (for example, some Samsung B/C/D series models or LG models with earlier versions of webOS), you can try installing client software.
However, most often, "software methods" for older TVs mean using a PC or laptop as an intermediary. You can connect your computer to the TV via HDMI and then mirror the image from your phone to the computer. This is a more complex approach, requiring a powered-on PC.
A more realistic option is to use a USB port to connect a flash drive containing content. While this isn't true Wi-Fi streaming, it's often the only way to display photos from your phone on the screen without buying adapters. Modern TVs can read the Android file system when connected via a cable.
If your TV has a connector SCART or S-VideoIf you have a HDMI port, the situation becomes more complicated. You'll need an active HDMI-to-AV converter, which will also need to be powered via USB. Wireless adapters paired with such converters are unstable due to signal quality loss during double conversion.
⚠️ Attention: Menu interfaces and function names may vary across TVs of different years. If you don't find the settings described, consult the official manual for your model, as manufacturers often change the operating logic.
Solving connection and quality issues
Even with a proper connection, users may encounter issues such as audio and video desync, low resolution, or intermittent connection drops. Most often, this is due to a congested Wi-Fi channel or a weak signal.
If the image is choppy, try moving your phone closer to the adapter or router. You should also disable background downloads and app updates on your smartphone, as they could choke the streaming channel. For stable operation, it's recommended to use a network connection. 5 GHz, if the equipment supports it.
If your phone doesn't detect the adapter, check your router's firewall settings. Sometimes AP Isolation prevents devices on the same network from communicating. This feature should be disabled in your router's settings.
What to do if there is no sound?
Often, the audio continues to play through the phone's speaker. In the casting settings (for example, in YouTube or Chrome), you need to manually select the audio output device or click the "Cast Audio" button.
Keep in mind that wireless streaming is a power-hungry process. When watching for long periods, it's recommended to connect your phone to a charger to prevent it from running out of battery at the most inopportune moment.
Is it possible to stream to a TV without HDMI?
Yes, but the quality will be poor. This requires Wi-Fi-to-AV converters (tulip), which are expensive and often produce unstable images. An alternative is to use set-top boxes with an AV output, if they are available.
Is internet required for Miracast to work?
No, internet access is not required. Miracast technology works on the principle of Wi-Fi Direct, creating a direct connection between the phone and the receiver. Internet access is only required if you want to stream online video, not local files.
Why is the image lagging while playing?
Wireless protocols aren't designed for real-time gaming due to encoding and signal transmission delays (input lag). For gaming, it's better to use a wired connection or directly connected game consoles.
