How to use a Samsung TV as a wireless monitor via a router

Modern technologies make it possible to transform a living room into a fully-fledged multimedia center, eliminating the need for unnecessary wires running throughout the room. Wireless connection Connecting your computer to a Samsung TV via a local network is a convenient way to show presentations, watch movies from your hard drive, or even play games on the big screen. Wi-Fi router As a data bridge, it provides a stable signal when a direct connection between devices is not possible or desirable.

To implement this scheme, your TV must support the technology Smart TV and be connected to the same network as your computer. It's important to understand that streaming quality directly depends on your router's bandwidth and the airwaves' congestion. In this article, we'll cover software and hardware setup methods in detail, as well as connection optimization techniques to minimize latency.

Before you begin setting up, make sure that both devices—the PC and the TV—are within a strong signal reception area. Router It should operate in dual-band mode (2.4 GHz and 5 GHz), as the 5 GHz frequency is preferable for transmitting high-definition video streams. This will avoid interruptions and image artifacts during active use. DLNA or Miracast protocol.

Technical requirements and equipment preparation

The foundation of a successful setup is the correct operation of your network equipment. router The router must support at least 802.11n Wi-Fi standards, and ideally 802.11ac (Wi-Fi 5) or newer. Transmitting a video signal with minimal or no compression requires high speeds, which older standards cannot provide. If the router is old, the image may become pixelated or freeze.

TV series Samsung Smart TV TVs are equipped with built-in Wi-Fi modules, but their performance varies depending on the model year. For modern 4K models, support for H.265 (HEVC) codecs and sufficient processing power for real-time stream decoding are critical.

⚠️ Attention: Wi-Fi data transfer speeds are always lower than those advertised by the router manufacturer due to protocol overhead and interference. The actual throughput of a 5 GHz channel can be 300–400 Mbps, which is sufficient for Full HD, but may be insufficient for uncompressed 4K HDR.
📊 What Wi-Fi standard does your router support?
802.11n (up to 300 Mbps)
802.11ac (Wi-Fi 5)
802.11ax (Wi-Fi 6)

The computer must also be connected to the power supply. If you are using a laptop, make sure it is not in power saving mode, which can limit power. Wi-Fi adapterDesktop PCs are best connected to a router via an Ethernet cable to reduce the load on the wireless airwaves and decrease ping, although a purely wireless setup of "PC via Wi-Fi -> Router -> TV via Wi-Fi" is also quite viable.

Screen Mirroring (Miracast) method via network

The easiest way to turn your TV into a second monitor is to use the built-in feature Miracast, which in the Samsung ecosystem is often implemented via the Wi-Fi Direct protocol or via a router, depending on the Tizen OS version. This method streams the entire Windows desktop to the TV screen.

To start working, press the button on the TV remote control Home and go to the signal sources menu. Select the item PC on TV or Screen MirroringIn some models you need to go to Settings → General → External Device Manager → Device List Manager and allow the connection.

On a computer running Windows 10 or 11, press the key combination Win + KThe "Connection" panel will appear on the right side of the screen. The system will begin searching for available displays. When yours appears in the list, Samsung TV, click on it. If the TV asks for permission, confirm it with the remote.

  • 📡 Make sure that the TV's external connection function is enabled in the Smart View menu.
  • 🖥️ In Windows, in projection mode, select "Extend" to use the TV as a full-fledged second monitor, or "Repeat" to clone the screen.
  • ⚙️ If the connection fails, check your Windows Firewall settings to allow network discovery.
  • 🔄 If errors occur, try restarting the Wi-Fi module on both devices.

Miracast is convenient due to its native nature, but it can introduce noticeable mouse cursor lag. This is because the video stream is encoded and transmitted over the network to minimize lag, but the physics of a wireless connection can make a difference. While this is acceptable for office work, it's not suitable for fast-paced gaming.

Stream media via DLNA and the Samsung Smart View app

If your goal is not to operate a computer, but to watch movies or photos, technology DLNA (Digital Living Network Alliance) would be the ideal solution. It allows you to stream content directly, using the TV as a renderer and the computer as a server. Samsung offers an official app for this. Samsung Smart View (for older OS) or built-in Windows tools.

In Windows 10 and 11, the media server feature is built in by default. Open Settings (Win + I), go to Apps → Apps & Features → Advanced Settings → Media ServerEnable the feature and give your PC a name. Next, click Setting up a media serverto select folders available to the TV.

Why is DLNA better for video?

DLNA transmits a pre-processed file, eliminating the need for on-the-fly encoding of the video stream, as Miracast does. This reduces the load on the PC's processor and ensures a more stable, stutter-free image, thanks to more efficient buffering.

Launch the app on your TV. Media (or Sources → PC). You'll see your computer's name in the list of devices. Logging in will give you access to your shared folders. Navigation is handled by the remote control, making it convenient for browsing photo albums or TV shows.

For more advanced control, you can use third-party servers like Plex or Kodi installed on your PC. They provide a beautiful interface with posters and descriptions that are streamed to Samsung Tizen via the corresponding client application on TV.

Characteristic Miracast (Screen Casting) DLNA (Media Server)
Transmission type Full screen stream (video + audio) Multimedia files (video, photos, music)
Interactivity Full (mouse control) Limited (remote control navigation)
Latency Medium/High (depending on the router) Minimum (with buffering)
Using a PC It is possible to work in parallel The PC may be turned off (if there is a NAS)

Setting up Windows Sharing (SMB)

A more professional approach to organizing file access is to create a shared network folder using the protocol SMBThis allows the Samsung TV to access the computer's file system as if it were a local drive. This method is often more stable than the built-in Windows DLNA server when working with large files.

Create a folder on your drive where you plan to store your movies. Right-click on it and select Properties → Access → Advanced settingsCheck the "Share" box and click Permissions, adding a group All with full rights (read and write).

An important step is to configure the network settings. Open Control Panel → Network and Sharing Center → Change advanced sharing settingsIn the "Private Network" profile, enable network discovery and file sharing. Also, disable password protection if you don't want to enter your login and password every time you connect to the TV (this only applies to trusted home networks).

☑️ Check SMB settings

Completed: 0 / 4

After setting up on the TV in the app Media Or, using a third-party player (such as VLC or MX Player, if they're installed on your TV), select the "Local Network" or "SMB" source. You should see your computer and the shared folder. If the system requires authorization, enter your Windows username and password.

Using third-party software for streaming

Windows' built-in tools are good, but specialized software often offers better optimization and lower latency. One of the best solutions for streaming images from a PC to a TV via a router is the program Steam Link (if you are a gamer) or general streamers like TeamViewer (for rare use) and Parsec.

Steam Link lets you stream games and desktop content with minimal latency using your graphics card's hardware encoding. Install the Steam Link app on your Samsung TV from the app store. AppsLaunch it and follow the on-screen instructions to pair it with a PC running the Steam client.

Another powerful tool is Universal Media Server or MiniDLAThese programs create more flexible transcoding rules. If your TV doesn't support the audio file format, the server will transcode it on the fly into a format that is understandable. Samsung TV, which will eliminate "format not supported" errors.

⚠️ Attention: When using third-party software, make sure exceptions are added to Windows Firewall for the relevant programs. Blocking incoming connections is the most common reason why a TV doesn't recognize a computer.

For users who need to control their computer with minimal latency (for example, for presentations), the combination is perfect SpacedeskThis application turns your TV into a fully-fledged second monitor over the network, transmitting a video signal at a high frame rate.

Troubleshooting and optimizing your connection

Even with an ideal setup, users may experience artifacts, audio desync, or intermittent connection drops. Most often, the problem lies in a congested airwaves or insufficient signal strength. A router located in a metal enclosure or far from the TV will not be able to provide a stable data stream.

Try changing the Wi-Fi channel in your router settings. Use Wi-Fi analyzers (such as those on your smartphone) to find the least congested channel. This is especially important for the 5 GHz band, as the channel bandwidth may overlap with neighboring networks.

It's also worth checking the power settings for your computer's Wi-Fi adapter. Find your wireless adapter in Device Manager, open its properties, and under the "Power Management" tab, uncheck "Allow the computer to turn off this device to save power."

If the image is jerky, try lowering the output resolution or frame rate in Windows settings (System → Display → Advanced display settings). Reducing the load on the communication channel often makes the picture smoother.

Questions and Answers (FAQ)

Why can't my Samsung TV see my computer on the network?

Most likely, you have network discovery disabled in Windows or your network profile is set to "Public." Switch the profile to "Private" in Wi-Fi settings and check your sharing settings. Also, make sure your antivirus isn't blocking the connection.

Can you play games on TV via Wi-Fi?

Yes, but quality depends on your router. For a comfortable gaming experience, you need a router that supports 5 GHz and Wi-Fi 5 (AC) or Wi-Fi 6 (AX). Use technologies like Steam Link or GeForce Now to minimize input lag.

How do I remove the black bars at the edges of the screen when connected?

This is a scaling issue. On your Samsung TV remote, find the button Menu or Tools, go to the picture settings and find the "Screen Format" or "Image Size" option. Select "Fit" or "Just Scan" (16:9) to remove overscan.

Does image quality depend on internet speed?

No, when connecting through a local router (DLNA, Miracast), the internet is not used. Data transfer speed is limited only by your router's performance and the distance between the devices. The internet is only required for online content (YouTube, Netflix).

Does my old Samsung TV support wireless monitor?

Miracast (Screen Mirroring) was introduced in Samsung F, H, J series models and later (approximately since 2013-2014). Older models can only work via DLNA (file viewing) or require the purchase of an external set-top box (Chromecast, Miracast adapter).
