Whether it's viewing vacation photos, presenting a work project, or playing a high-definition movie, it's all easily accomplished via a local network. The key is that both devices are within the same router range.
In this article, we'll take a detailed look at all available streaming methods, from built-in Windows features to third-party apps. You'll learn how to set up DLNA, use the protocol Miracast and even connect devices Apple to the TV SamsungWe will also cover network optimization to eliminate image lag and jerkiness.
Network requirements and preparatory settings
Before you begin pairing your gadgets, you need to make sure your local network is working properly. Connection stability — this is the foundation upon which high-quality multimedia streaming is built. If the router is intermittent or the signal is too weak, no TV settings will help prevent audio and video from becoming out of sync.
Both devices, the computer and the TV, must be connected to the same Wi-Fi network. This is critical, as device discovery protocols often fail if one is connected to a guest channel or using mobile data via a hotspot.
⚠️ Note: If your router supports dual-band mode (2.4 GHz and 5 GHz), make sure both devices are in the same frequency range or that the Client Isolation feature is enabled on the router, which should be disabled.
To check the connection quality, you can run a speed test on your computer. For comfortable viewing of video in the following resolution: 4K The recommended speed is not less than 25 MbpsIn case of using the standard Wi-Fi 5 (802.11ac) or newer, the throughput is usually sufficient for large files.

|---|---|---|
| Protocol | Data transfer method | DLNA / UPnP |
| Video codec | Stream compression format | H.264, H.265 (HEVC) |
| Permission | Maximum quality | up to 3840x2160 (4K) |
