Fortunately, wireless data transmission technologies allow for high-speed, low-latency image streaming, turning an ordinary PC into a clutter-free gaming experience. Smart TV into a full-fledged gaming monitor.
To successfully implement this scenario, the quality of your home network is critical. Your wireless connection must provide a stable data stream, as any signal interruption will result in image artifacts or a complete disconnect during a gaming session. In this article, we'll explore various connection methods, from built-in Windows features to specialized apps, that will help you achieve the desired result.
Before you begin setting up, make sure your equipment meets the minimum requirements for HD video streaming. We'll cover the protocol details. Miracast And DLNAWe'll also discuss why using gaming platforms can provide better responsiveness. Proper preparation will prevent unnecessary issues with lag and audio desync.
Network and hardware requirements for stable streaming
The foundation of any wireless broadcast is a router, which must support modern communication standards. The ideal option would be to use a range 5 GHz, which provides higher throughput and is less susceptible to interference from neighboring networks and household appliances. If your router only operates at 2.4 GHz, you may experience image instability, especially during fast-moving scenes.
The computer and TV should be within range of a strong signal, preferably within line of sight or through a single non-load-bearing wall. The distance between devices directly impacts data transfer speed, so placing the router in a central location in the apartment is often key to success. Powerful antennas or mesh systems can significantly improve coverage in larger spaces.
⚠️ Attention: Wi-Fi bandwidth can drop during peak hours when other devices in the home are actively consuming data. For gaming, reserving a channel or using your router's QoS settings is critical.
In terms of hardware, your PC's graphics card should support hardware encoding of video streams, which will reduce the load on the CPU. NVIDIA NVENC or AMD AMF They allow for efficient image compression before sending it over the network. The TV, in turn, must have a sufficiently powerful processor to quickly decode the incoming video signal.
Using built-in Windows features: Projection and Miracast
The easiest way to start broadcasting is to use the native capabilities of the Windows 10 or 11 operating system. Technology Miracast Allows you to stream your computer screen to a compatible TV without installing additional software. To get started, make sure both devices are connected to the same Wi-Fi network, then press the key combination Win + K on the keyboard.
In the "Connection" menu that opens, the system will begin searching for available displays. Select your TV from the list, and within a few seconds, your desktop will appear on the big screen. This method is good for static content or leisurely gaming, but can introduce noticeable input lag, known as input lag.
Projection settings can be flexibly configured through the system menu. Go to Settings → System → Project to this PCto check the feature's status and change connection requirements. You can also adjust the resolution and refresh rate to optimize performance.

The program will automatically find your PC on the local network. After pairing your controller, you'll have access to your entire game library, allowing you to play right from the comfort of your couch.
An important advantage is the support Hardware Decoding on the TV side, which reduces network load. You can adjust the stream quality by limiting the bitrate or resolution if the network can't handle it. A feature is also available Game Streaming, which optimizes the video stream specifically for dynamic content.
☑️ Setting up Steam Link
It's worth noting that Steam must be running on your computer for this feature to work. The app not only lets you play games but also manage your desktop in Big Picture mode. This turns your TV into a fully-fledged gaming console, harnessing the computing power of your PC.
Streaming via Google Chrome and Chromecast
Owners of TVs with support Chromecast built-in or a connected set-top box can use the Google Chrome browser to cast a tab or the entire screen. This method is universal and works on any operating system with Chrome installed. To launch, open the browser menu (the three dots in the corner) and select Broadcast... (Cast).
The system will prompt you to select a broadcast source: you can send just a browser tab, the entire desktop, or a specific application. When selecting "Broadcast Desktop," ensure the quality settings are set to maximum to minimize compression artifacts. Audio is also transmitted along with the video stream.
This method is convenient for showing presentations or watching videos, but it may be less optimal for gaming due to browser encoding issues. However, if other methods are unavailable, this is a viable alternative. Image quality directly depends on processor power and Wi-Fi speed.
| Method | Latency (ms) | Quality | Complexity |
|---|---|---|---|
| Miracast | 50-150 | High | Low |
| Steam Link | 10-40 | Optimal | Average |
| Chrome Cast | 100-200 | Average | Low |
| NVIDIA Shield | 5-20 | Maximum | High |
Specialized solutions: NVIDIA GameStream and Moonlight
For video card owners NVIDIA GeForce there is technology GameStream, which is considered one of the best in terms of image quality. Although NVIDIA officially announced the end of support for this feature in its drivers, it still works and has an excellent alternative in the form of an open source project. Moonlight.
Moonlight is an open-source client that uses the GameStream protocol to stream games from your PC to various devices, including Android Smart TVs. It offers incredibly low latency and resolution support. 4K at 60 FPS Or even 120 FPS with powerful hardware. This setup requires installing the Sunshine server on your PC if official NVIDIA support is disabled.
The advantage of this method is support HDR and a high refresh rate, making the image virtually indistinguishable from local playback. The protocol efficiently utilizes available network bandwidth by dynamically adjusting the bitrate. It's the choice of enthusiasts who demand the highest quality.
