Before attempting to connect devices, make sure they meet the minimum requirements:

• 📺 Samsung TV: models with Smart TV at the base Tizen OS (released after 2015). For Miracast support needed Wi-Fi Direct (checked in Settings → General → About).
• 📱 Smartphone:
  • Android 6.0+ with support Miracast (included in Settings → Display → Wireless Display).
  • iPhone with iOS 12+ (only for AirPlay 2, available on models QLED 2019+ And Frame TV).
• 📶 Router: dual-band (2.4 GHz + 5 GHz) with support WPA2-PSK or WPA3For stable 4K streaming, a speed of at least 300 Mbps.

A critical error many users make is trying to connect to different networks. The TV and phone must be on the same Wi-Fi network., even if you use Wi-Fi Direct. Exception - mode Screen Mirroring on some models Samsung Galaxy, where a direct access point is created.

⚠️ Warning: On TVs Samsung series J (2016–2017) and older models K support may be lacking 5 GHzForce the router to switch to the mode 2.4 GHz or use Wi-Fi Direct.

3. Method 2: Miracast (Wi-Fi Direct) - without a router

Miracast — a universal wireless screen sharing protocol that works without a router. It creates a direct connection between your phone and TV, which is useful in areas with poor Wi-Fi signal. However, it has some limitations:

• 🎮 Input lag when gaming (~50–100 ms).
• 🔊 Sound is not always transmitted (depending on the phone model).

If standard methods don't work or you need more advanced features, try these tricks:

• 🔧 Developer Mode on TV: turn it on through Settings → General → About (click 7 times on Model number). Then activate Debugging over Wi-Fi in the developer menu. This will allow you to use ADB to fine-tune the connection.
• 🌐 Proxy server to bypass blocking: if the router blocks multicast, set up a local proxy (for example, via Raspberry Pi) to redirect traffic.
• 📡 5 GHz priorityOn dual-band routers, force the TV to connect to the network. 5 GHz (even if the phone is on 2.4 GHz). This will reduce delays when mirroring.

For enthusiasts: If your TV supports SSH (checked through nmap -p 22 [TV_IP]), you can manually configure the network settings. For example, increase MTU to reduce packet loss:

echo "1500" > /proc/sys/net/ipv4/ip_no_pmtu_disc

⚠️ Warning: Modifying your TV's system files may void your warranty. Before experimenting, back up your settings using Settings → Support → Self-diagnosis → Backup.

7. Troubleshooting: Why won't it connect?

If the connection is interrupted or the devices do not "see" each other, check:

Complex case: if the TV connects, but the broadcast is artifacted, check the settings QoS on the router. Prioritize traffic for the TV's MAC address (you can find it in Settings → Network → Network Information).
