In this article, we'll examine all the current connection methods, their pros and cons, and provide checklists for quick setup.

Modern televisions (starting with models 2018–2019) and laptops support several wireless transmission protocols: Miracast, AirPlay, Google Cast And DLNAThe choice depends on the laptop's operating system, TV model, and even the router version. For example, for Windows 11 Miracast is optimal, and for macOS — AirPlay. But there are also universal solutions that work on any device.

We tested all methods on TVs Samsung QLED 2023, LG OLED C2, Sony Bravia X90J and laptops with Windows 10/11, macOS Ventura And Linux Ubuntu 22.04In 90% of cases, connecting takes no more than 5 minutes if you select the correct protocol and configure the network. The main thing is to make sure both the laptop and TV are connected. one Wi-Fi network (or to the router in access point mode).

1. Preparation: What to check before connecting

Before setting up your stream, make sure your equipment meets the minimum requirements. This will save you time and avoid errors like "device not supported."

TV requirements:

• 📺 Smart TV with Wi-Fi support (models not older than 2016). If the TV does not have smart functions, you will need an external adapter of the type Google Chromecast or Mi TV Stick.
• 🔄 Updated firmware. Outdated software may not support modern protocols. Update your TV via Settings → Support → Software Update.
• 📶 Connect to the same Wi-Fi network as your laptop (or to a router in wireless mode) AP). If you are using a mobile hotspot, make sure that the mode is enabled on your laptop. Mobile hotspot.

Laptop requirements:

• 💻 For Windows: version not lower 10 (1803) with support Miracast (checked in Settings → System → Display → Connect to a wireless display).
• 🍎 For macOS: version not lower Monterey 12.0 for AirPlay 2.
• 🐧 For Linux: will need to be installed gnome-network-displays or scrcpy (instructions below).
• 🔋 Battery charge is at least 30%. Wireless streaming consumes a lot of energy.

⚠️ Attention: If your router operates at a frequency 5 GHz, but the TV only supports 2.4 GHz (or vice versa), the connection may not work. Check the network settings in the router's admin panel.

Also, make sure that power saving modes that could interrupt the connection are disabled on your laptop and TV. For example, Windows this is a setting Power → Advanced settings → Adapter settings → Wireless network → Power saving mode → Maximum performance.

2. Method 1: Miracast (for Windows and Android)

Miracast — the most universal protocol for wireless screen sharing, built into Windows 10/11 and most modern TVs. It works without the internet, creating a direct connection between devices (peer-to-peer), which reduces latency.

How to connect:

1. Activate the mode on your TV Screen Mirroring (name may differ):
   • 📺 Samsung: Settings → General → Screen Mirroring
   • 📺 LG: Settings → Connection → Screen Sharing

On a laptop with Windows click Win + K (or Settings → System → Display → Connect to a wireless display).

From the list of available devices, select the name of your TV.

Confirm the connection on TV (you may be asked to enter a PIN code).

Problems and solutions:

• ❌ The laptop does not see the TV: Check if your Wi-Fi adapter supports it MiracastTo do this, enter the following in the command line:

  netsh wlan show drivers

  Look for the line Miracast support: YesIf not, update the driver or use an external adapter (for example, TP-Link TL-WDN5200).

• ❌ The image is lagging: switch the router to a frequency 5 GHz or reduce the screen resolution on your laptop to 1280×720.
