Quick connection method via control panel
The fastest way broadcast the screen In Windows 11, use the built-in Projects sidebar. This method doesn't require searching for devices in General Settings and only takes a few seconds. It's ideal for situations when you need to quickly share a document or switch to a larger screen to watch a video.
To get started, press the key combination Win + K on the keyboard. The "Connection" panel will appear on the right, where the system will begin searching for available displays within Wi-Fi range. If the TV is turned on and ready to pair, its name will appear in the list within a few seconds.
After selecting the device, a connection confirmation prompt may appear on the TV screen. Use the remote control to grant access to the laptop. After that, the desktop image Windows 11 will appear on the big screen. You can choose the operating mode: duplicate screens, extend the desktop, or output only to the second screen.
☑️ Check before connection
It's important to note that image quality directly depends on signal strength. If the distance between the router (or devices in a direct connection) is large, you may experience compression artifacts or audio desynchronization. In this case, it is recommended to reduce the distance or use a screen extension method to reduce the load on the channel.
Setting up via Windows 11 system settings
If the hotkeys don't work or you need more detailed display adjustments, you should access the main settings menu. Here you can manage projection modes and adjust resolutions for your specific TV. This is especially helpful if the image appears blurry or doesn't fill the entire screen.
