Preparation of equipment and network infrastructure
Before pairing your devices, you need to ensure the basic settings are correct. Both devices—the mobile phone and the TV—must be connected to the same wireless network. This is a fundamental requirement of local data transfer protocols, without which device discovery is impossible.
Make sure the software on both ends of the connection is up to date. On the TV, go to the menu Settings → Support → Software Update and run the check. Outdated firmware versions Tizen OS may not contain necessary security patches or new codecs for streaming.
⚠️ Important: If your router broadcasts 2.4 GHz and 5 GHz networks under different SSIDs, make sure both devices are connected to the 5 GHz network. Separating traffic on different frequencies within a single router can sometimes block discovery protocols (DLNA/Miracast).
To ensure maximum signal stability, it is recommended to place the router within direct line of sight of the TV, if possible. Obstacles such as concrete walls or metal structures can cause image artifacts and audio delays when mirroring.
Using Smart View to mirror your screen
The main tool for Android smartphone owners is technology Smart View is a native feature built into the One UI shell that uses the Miracast protocol to transmit video streams without the compression common with some cloud services.

Connecting Apple iPhone and iPad devices (AirPlay 2)
Equipment owners Apple can use the built-in protocol support AirPlay 2, which is now available on most modern Samsung TVs. This ensures seamless integration without the need to install additional apps on the TV.
Make sure AirPlay is enabled on your TV. To do this, go to Settings → General → Apple AirPlay Settings and toggle the switch to the "On" position. You can also set a passcode requirement here for increased security.
On your iPhone or iPad, open Control Center (swipe down from the top-right corner on newer models or up from the bottom on older models). Tap the Screen Mirroring icon (two rectangles) and select your TV from the list.

Solution: Use the built-in app on your TV or the "Cast" feature within the player app itself, rather than mirroring the entire screen.
There are also specialized applications for gamers that allow for low-latency display. However, for a comfortable gaming experience, it's still recommended to use a wired connection or specialized gaming consoles, as Wi-Fi always introduces some input lag.
Diagnosing problems and optimizing connections
Despite technological advances, wireless connections can be unstable. Common issues include audio and video desync, dropped resolution, or complete connection failure. The first step should always be to reboot the router and both devices.
If the image is choppy or has low resolution, check your Wi-Fi channel load. Neighboring routers may be causing interference. Try manually changing the channel in your router settings to a less crowded one (e.g., 1, 6, or 11 for 2.4 GHz, or any available channel for 5 GHz).
It's also worth checking your smartphone's power-saving settings. Aggressive power-saving modes can limit Wi-Fi activity in the background, leading to streaming interruptions. Add the streaming app to the exceptions list.
In some cases, resetting the network settings on your TV can help. To do this, go to Settings → General → Network → Reset network settingsYou'll need to re-enter your Wi-Fi password after this, but this often resolves issues with frozen network services.
Frequently Asked Questions (FAQ)
Is it possible to mirror a Samsung TV without Wi-Fi?
Yes, this is possible with a cable. For modern Samsung phones, you'll need a USB-C to HDMI adapter. Simply connect the cable to your phone and TV, then select the appropriate input source (HDMI) on your TV remote. This feature is called Samsung DeX, or Easy Mirroring.
Why is the sound only coming from my phone when streaming YouTube?
