Connecting a TV as a Monitor via Wi-Fi: All Methods and Instructions

Using your TV as a monitor wirelessly opens up new possibilities for working, gaming, and viewing content. While a wired HDMI connection is relatively straightforward, wireless image transmission requires knowledge of the nuances of technology, device compatibility, and proper setup. In this article, we'll cover all the current connection methods—from the standard Miracast to proprietary solutions such as Apple AirPlay or Samsung Smart View.

The main advantage of a Wi-Fi connection is the absence of wires and the ability to place a laptop or PC anywhere from the screen (within the network coverage area). However, not all TVs support wireless streaming out of the box, and some methods can introduce delays in image display. We'll help you choose the best option for your TV model and avoid common pitfalls.

What technologies allow you to use a TV as a monitor via Wi-Fi?

There are several wireless protocols for transmitting images to a TV. The choice depends on your PC/laptop's operating system, TV model, and the required image quality. Let's look at the main ones:

• 🔄 Miracast — a universal standard for Windows, Android, and some Smart TV models. Works without a router (direct connection) Wi-Fi Direct), but requires support from both devices.
• 🍎 Apple AirPlay — proprietary technology for devices Apple (Mac, iPhone, iPad). Supported by TVs LG, Samsung, Sony with the appropriate software.
• 📡 DLNA/UPnP — a protocol for broadcasting media files (photos, videos, music), but not suitable for screen mirroring in real time.
• 🖥️ Proprietary solutions - For example, Samsung Smart View, LG Screen Share or Sony Video & TV SideViewThey only work with TVs of their own brand.
• 🌐 Cloud services — Steam Link, Moonlight (for games), TeamViewer (for remote control). Requires a stable internet connection.

It is important to understand that DLNA is not designed for desktop mirroring - it only streams ready-made media files with a delay.. Suitable for a complete monitor replacement Miracast (for Windows/Android) or AirPlay (for Apple). Proprietary brand utilities often offer better quality but are limited in compatibility.

⚠️ Note: Some TVs older than 2018 may not support Miracast or AirPlay even after a firmware update. Check your model's specifications on the manufacturer's website.

Hardware requirements for wireless connection

Before you begin setup, make sure your devices meet the minimum requirements. Here's what you'll need:

Pay special attention Wi-Fi frequency. Range 5 GHz provides lower latency and a more stable signal, but has a smaller coverage area than 2.4 GHzIf your TV and computer support Wi-Fi 6, use it - it will reduce lag when streaming videos or games.

⚠️ Attention: On laptops with hybrid graphics (NVIDIA Optimus or AMD Switchable Graphics) Before connecting, enable the discrete graphics card in the power settings. Integrated Intel graphics may not be able to handle real-time video encoding.

Connecting via Miracast (for Windows and Android)

Miracast — the most universal way to mirror your screen over Wi-Fi, working on most modern devices. The technology uses Wi-Fi Direct, so it doesn't require a router connection. Instructions for Windows 10/11:

⚠️ Warning: On TVs Samsung AirPlay may be disabled after a factory reset. To turn it back on, go to Settings → Support → Self-diagnosis → Reset Smart Hub and repeat the setup.
