⚠️ Caution: When transferring a large high-resolution video file (4K), make sure your router is operating at 5 GHz, as the 2.4 GHz band may not provide sufficient throughput.
If the connection fails the first time, try rebooting your router and TV. Sometimes the network settings cache can prevent devices from being detected. After rebooting, repeat the search process.
Using Chromecast and Android TV technology
Many modern TVs, including models from Sony, Philips, TCL, and Xiaomi, run the Android TV operating system or have built-in Chromecast support. This allows you to stream content directly from apps like YouTube, Netflix, or the Chrome browser without having to mirror the entire screen.
To get started, make sure the YouTube app is running on your TV or your Chromecast is in standby mode. On your smartphone, open the same app and find the casting icon (a rectangle with Wi-Fi waves in the corner). Tap it.
In the list that appears, select the name of your TV. If the devices are on the same network, the connection will be established automatically. You can control playback, volume, and video queue directly from your phone, using it as a remote.

If your TV doesn't natively support AirPlay, you can use an Apple TV. Both devices must be connected to the same Wi-Fi network. Open Control Center on your iPhone (swipe down from the upper-right corner or up from the bottom).
Tap the "Screen Mirroring" button (two rectangles). Select your TV from the list. Your smartphone's screen will be mirrored to your TV. To stop mirroring, tap the button again and select "Stop Mirroring."
| Parameter | Android (Miracast/Chromecast) | iOS (AirPlay) | DLNA |
|---|---|---|---|
| Transmission type | Mirroring / Streaming | Mirroring / Streaming | Files only |
| Delay | Low / Medium | Minimum | Absent |
| Quality | Depends on the signal | High | Original |
| Phone battery | It is consumed quickly | It is consumed quickly | Economical |
When using AirPlay, it's important to keep your phone close enough to the router to ensure a stable data stream. Interruptions in the signal can cause video buffering.
Alternative methods through applications
If standard methods don't work or your TV's functionality is limited, you can use third-party apps. Popular apps for Android include: Web Video Caster or BubbleUPnPThey allow you to stream video from your browser or file manager to your TV via the DLNA protocol.
Install the app on your phone and make sure the corresponding receiver (often built into media players) is enabled on your TV. Open the video file or link in the app and click the Cast button. The program will find the device on the network and begin casting.
There are similar solutions for iOS, for example, Cast to TV or XCastThey operate on a similar principle: searching for a device on the local network and transmitting a media stream. These apps can often convert formats on the fly if the TV doesn't support the video codec.
Some TV manufacturers offer their own apps for remote control and streaming, such as Panasonic Video & TV SideView or Philips MyRemote. These apps offer advanced functionality beyond what's available in the standard OS.
Troubleshooting connection issues and errors
The most common problem is that devices can't see each other. This almost always means they're connected to different networks. Check to see if your phone is using mobile data (4G/5G) instead of Wi-Fi. Also, dual-band routers (2.4 and 5 GHz) can create a virtual divide, although modern routers typically combine them into a single network.
Another possible cause could be outdated software. Go to your TV settings and check for system updates. Manufacturers regularly release patches that improve compatibility and connection security.
⚠️ Note: Menu interfaces and item names may vary depending on your TV model and year. If you don't find an exact match, look for similar sections in the network settings.
If the stream is choppy or of poor quality, try moving the router closer to the TV or using a Wi-Fi extender. Also, close background apps on your phone that may be consuming data.
Frequently Asked Questions (FAQ)
Is it possible to connect a phone to a TV without the Internet?
Yes, you can. Internet access is not required for a local Wi-Fi network (DLNA, Miracast, AirPlay) to work. The main thing is that both devices are connected to the same router, which creates the local network. Some TVs allow you to create a Wi-Fi Direct hotspot, which your phone can connect to directly.
Why doesn't the TV see the phone, even though both are on Wi-Fi?
Most often, the problem lies in the router settings, which may prohibit communication between clients (AP Isolation). Also, check that the devices don't have different dates and times, which can cause security certificate errors. In rare cases, resetting the network settings on your phone may help.
Does connecting a phone affect picture quality?
Picture quality depends on the Wi-Fi signal strength and channel congestion. If the signal is weak, the system may automatically reduce the video resolution to prevent buffering. For viewing 4K content, a wired connection or a very strong 5 GHz signal is recommended.
Is it safe to use public Wi-Fi for streaming?
Using public Wi-Fi networks for streaming is not recommended, as other network users could potentially access your device. For secure mirroring, it's best to use a mobile hotspot created on your phone itself, if your TV supports it.
