Modern gaming has long since expanded beyond small monitors, and many users are eager to transfer gameplay to a large TV screen for a truly immersive experience. However, running long HDMI cables through an entire apartment or house isn't always convenient, and sometimes it's technically impossible due to layout or furniture arrangement. This is where wireless technologies come in, allowing you to stream images from a powerful computer to a screen. Smart TV via your home Wi-Fi network.
This method requires proper configuration of both software and network hardware to minimize input delays, known as input lagUnlike a wired connection, wireless data transmission is subject to interference, distance, and router quality, so a number of technical requirements must be met for comfortable gaming. We'll explore all available options, from built-in Windows features to specialized apps, that will help you enjoy gaming on the big screen without the hassle of wires.
It's worth noting right away that streaming quality directly depends on your channel's bandwidth and signal stability. If you plan to play fast-paced shooters or competitive games where every millisecond counts, you'll need Wi-Fi 5 GHz or even Wi-Fi 6. For more sedate genres, such as strategy or RPG, the standard range is also suitable, but with certain limitations regarding image quality settings.
Technical requirements and network preparation
Before setting up the software, you need to ensure that your local network can handle a real-time high-definition video stream. The standard 2.4 GHz frequency is often overloaded by neighboring routers and household appliances, resulting in micro-stuttering and compression artifacts. For stable game streaming from your computer to your TV, it is highly recommended to use the 2.4 GHz frequency range. 5 GHz, which provides higher speed and less interference.
⚠️ Important: If your router is dual-band, make sure both your PC and TV are connected to the 5 GHz network. Using different bands (one 2.4, the other 5) can significantly reduce data transfer speeds between devices.
An important parameter is not only the frequency, but also the wireless communication standard. Modern routers with support Wi-Fi 6 (802.11ax) or at least Wi-Fi 5 (802.11ac) They perform significantly better than older models. The physical location of the devices also matters: a clear line of sight between the router and the receiving device (TV) or transmitting device (PC) improves the signal, although for indoor scenarios, being in the same room is sufficient.
- 📶 Use a router that supports 802.11ac or later for maximum throughput.
- 🔌 Connect your computer to the router via an Ethernet cable, if possible, to free up Wi-Fi bandwidth for transmitting the video stream to your TV.
- 📺 Make sure your Smart TV supports Miracast technology or has an app for receiving streams (for example, Steam Link).
- 🚀 Check your local network speed by running a speed test between your PC and another device on the same network.
Don't ignore the power of your computer itself. Decoding a video stream on your TV requires resources, but the main rendering and encoding load falls on your PC's GPU. Video cards from NVIDIA And AMD have built-in hardware codecs (NVENC and VCE, respectively), which effectively compress images before sending them over the network, minimizing the load on the processor.
Using the built-in Projection feature in Windows
The simplest and most accessible method that does not require installing third-party software is technology MiracastBuilt into the Windows 10 and 11 operating systems, this feature allows you to mirror your screen or extend your desktop onto a compatible TV, turning it into a second monitor. To activate this mode, you typically need to launch the "Cast" app (Screen Mirroring, Smart View, or similar, depending on the brand) on your TV.
On a computer, the setup process is also straightforward: just press a key combination Win + Kto open the connection panel. Your TV should appear in the list of available devices. Once paired, the system will create a direct Wi-Fi Direct connection or use an existing network to transmit the image. Image quality in this mode is often limited to 1080p and 30 or 60 frames per second, which may not be sufficient for fast-paced games.
The main drawback of standard screen mirroring is its lack of optimization specifically for gaming. You may experience a noticeable delay between mouse movement and the on-screen cursor, as well as occasional stuttering. However, for turn-based strategy games, card games, or watching PC videos on a big screen, this method is ideal due to its simplicity and native integration.
- 🖥️ Click
Win + Kto quickly open the wireless display connection menu. - ⚙️ In Windows display settings, select "Second screen only" mode to dim the image on your PC monitor and direct GPU resources only to the TV.
- 🎮 To reduce latency, select the "Gaming" mode in the "Projection Settings" menu if it is available in your OS version.
Streaming via the Steam Link app
If you are a user of the platform Steam, then you have access to one of the most optimized solutions for game streaming - technology Steam Remote PlayTo implement this scheme on a TV (if it runs Android TV, Tizen from Samsung, or webOS from LG), you need to install the official application Steam LinkThe Steam client must be running on your computer and logged in under the same account.
The main advantage of this method is that the computer handles all the heavy-lifting of rendering, and the finished video stream, compressed with minimal quality loss, is sent to the TV. The application automatically scans the network, finds the running Steam application on the PC, and prompts you to start a session. The Steam Big Picture Mode user interface is adapted for joystick control, making the experience as comfortable as possible.
☑️ Preparing Steam Link
You can manually set the bitrate and resolution in the Steam Link app settings on your TV. By default, the system automatically selects optimal settings, but for competitive games, you can limit the resolution to 1080p and lock it at 60 FPS to reduce network load. H.264 And HEVC codecs provide an excellent picture even with an imperfect signal.
⚠️ Note: App interfaces and available codecs may change with TV firmware updates. We recommend checking the current supported formats in the "About" section or on your TV manufacturer's official website.
Particular attention should be paid to controls. Steam Link allows you to connect Bluetooth gamepads directly to your TV, reducing the load on your PC's wireless network. However, if you use a wired connection between your gamepad and your PC, latency may be slightly lower since the signal doesn't have to travel twice through the network.
Alternative solutions: Moonlight and Parsec
For those looking for maximum performance and minimal latency, there are specialized applications such as Moonlight Game Streaming And ParsecMoonlight is an open-source client that uses NVIDIA GameStream technology (or its emulation via Sunshine on AMD/Intel graphics cards). This solution is considered the "gold standard" for image quality and responsiveness, often surpassing even wired solutions in subjective terms.
Parsec, in turn, was originally designed for remote work and desktop access, but has proven itself in gaming thanks to its extremely low latency. Unlike Steam, Parsec doesn't tie you to a single platform's library—you can stream games from Epic Games Store, GOG Or even console emulators. Installing the client on your TV (via Android TV) and the host on your PC takes just minutes.
What is the difference between Moonlight and Parsec?
Moonlight is optimized for local networks and delivers the best picture quality on ideal Wi-Fi, using NVENC hardware encoding. Parsec handles unstable internet connections better and offers more advanced features for remote access, but may require slightly more CPU resources during encoding.
Both apps allow fine-tuning of network settings. You can adjust the maximum bitrate, select a preferred codec (H.264, H.265/HEVC, AV1), and configure buffering. For Moonlight, an NVIDIA graphics card (for native support) or a server installation are critical. Sunshine for AMD and Intel cards, turning your PC into a universal streaming host.
- 🌙 Moonlight offers the lowest input lag of any wireless solution.
- 🌐 Parsec is ideal if you want to play not only at home, but also remotely via the internet.
- 🛠️ Moonlight on AMD/Intel cards requires installation of additional Sunshine software.
DLNA and Media Servers: What They're Good For
Users often confuse game streaming with technology DLNA (Digital Living Network Alliance). It's important to understand that DLNA is designed exclusively for transferring media files (video, photos, music) and does not support real-time interactive image streaming. You won't be able to launch a game on your PC and stream it to your TV via a DLNA server, as the protocol doesn't support the low-latency, two-way data exchange required for gaming.
However, if your goal is to run an old console emulator or an indie game that runs in windowed mode and simply display the image, DLNA won't help. But if you want to watch a video walkthrough or stream from your PC on your TV, using a media server (such as the one built into Plex or Kodi) would be a great solution. In this case, the computer acts as a server, and the TV simply plays the video stream.
This method isn't considered for gaming purposes, but knowing this difference helps avoid confusion when setting up a home media server. If you see a DLNA option in your TV settings, know that it's for photos and videos, not Real-time Gaming.
Comparing Methods and Troubleshooting
The best method depends on your equipment and quality requirements. To help you organize the information and make your decision, we've prepared a comparison table of the main connection methods.
| Method | Latency | Picture quality | Difficulty of setup |
|---|---|---|---|
| Miracast (Windows) | High | Medium (1080p) | Low |
| Steam Link | Low | High (up to 4K) | Average |
| Moonlight | Very low | Excellent (HDR) | High |
| Parsec | Low | High | Average |
If you're experiencing compression artifacts (squares in the image) or frequent connection drops, first check your Wi-Fi channel load. Try switching your router to a less congested channel in the settings (Channel Width (This can be increased to 80 MHz for 5 GHz). Disabling background downloads on other devices on the network also helps.
Audio remains an important aspect. When connected wirelessly, audio is also transmitted over the network, which can cause audio lag. Streaming apps often have options in their settings to buffer audio or process it separately. If audio lag is noticeable, try switching the audio output in Windows to the "Steam Streaming Speakers" device or a similar device created by the streaming app.
Frequently Asked Questions (FAQ)
Is it possible to play online shooters via Wi-Fi streaming without lag?
This is possible, but requires ideal conditions: a Wi-Fi 6 router, a PC connected via cable, and a TV within line of sight of the router. However, wireless is not recommended for professional esports due to jitter instability.
Do I need a gamepad to play via Steam Link?
Not required, but highly recommended. A keyboard and mouse can be routed over the network, but controlling them from the couch is inconvenient. Many modern TVs support direct connection to Bluetooth gamepads.
Why is the picture blurry or squared?
These are signs of insufficient bandwidth. Reduce the bitrate in your streaming app settings or switch to the 5 GHz band. Also, check to see if the encoder is overloading your PC's processor.
Does this work on older non-Smart TVs?
Directly – no. Older models will require an external set-top box (Android Box, Apple TV, Chromecast with Google TV), onto which you can install the necessary client app (Moonlight, Steam Link, Parsec).
