Modern technology allows you to completely eliminate unnecessary wires in the living room, turning viewing photos on a large screen into a comfortable process. Wireless data transmission has become a standard, accessible to every smart TV and laptop owner. You no longer need to search for USB drives or manually transfer files if your devices are on the same network.
The basis of such interaction is local Wi-Fi network, which connects your computer and TV into a single ecosystem. Whether you use Windows 10, 11 Whether you're using a Mac or another operating system, the operating principle remains similar, although the menu paths may differ. Understanding the basic principles of synchronization will help you avoid common connection errors.
In this article, we'll take a detailed look at all current content output methods: from built-in operating system functions to specialized media servers. You'll learn how to set up DLNA server, use the mode Miracast for screen mirroring and what nuances should be taken into account to ensure stable transmission of high-resolution data.
⚠️ Attention: Wireless transmission quality directly depends on your Wi-Fi network's bandwidth. For viewing 4K content or RAW photos, using the 5 GHz frequency is highly recommended, as the 2.4 GHz standard may not provide sufficient streaming speed.
Technical requirements and equipment preparation
Before you begin setting up, you need to make sure that your equipment meets the minimum requirements for the correct operation of multimedia protocols. Device compatibility — a key factor for success. Most modern Smart TVs released in the last 10 years support standard media transfer protocols, but older models may require additional adapters.
Both devices - the computer and the TV - must be connected to the same Wi-Fi networkThis is a critical requirement that is often overlooked by beginners. If your router broadcasts the network on two frequencies (2.4 GHz and 5 GHz) with different names (SSIDs), make sure both devices are connected to the same frequency or that the Client Isolation feature is enabled on the router, which prevents data exchange between devices within the network.
Also, check that your PC's network card drivers and your TV's firmware version are up to date. Manufacturers regularly release updates to improve stability. DLNA And AirPlay Protocols. Outdated software may prevent the TV from seeing the computer in the list of available devices.
To ensure maximum speed for transferring large amounts of data, such as a gallery of thousands of high-resolution photos, it is recommended to place your computer and router within a strong signal reception area. The distance between the transmitting device and the router should not exceed 10 meters if there are walls., since the 5 GHz signal is greatly attenuated when passing through obstacles.
Using built-in Windows features for broadcasting
The Windows operating system offers native tools for quickly connecting to wireless displays. This method, known as Miracast or "Wireless Monitor," allows you to broadcast your entire screen or extend it onto a TV. This is ideal if you need to show a presentation or quickly display the contents of a folder.
To activate the connection, press the key combination Win + K on the keyboard. The system will begin searching for available wireless displays within range. On the TV, you may need to launch the appropriate application, often called Screen Share, Miracast or simply "Broadcast" in the signal sources menu (Source).
- 📺 Press the "Source" or "Input" button on the remote control and select "Screen" or "Wireless Display".
- 💻 On your computer, select the name of your TV from the list that appears.
- 🔒 If a PIN is required, it will be displayed on the TV screen - enter it in the field on your PC.
- 🖥️ Once connected, you can select the operating mode: “Duplicate”, “Extend” or “Second screen only”.
This method creates a direct connection, which can be susceptible to interference. If you notice cursor lag or image stuttering, try lowering your computer's screen resolution before connecting. Also, keep in mind that mirroring the entire screen increases your laptop's power consumption and drains the battery faster.
⚠️ Attention: Some antivirus programs and firewalls may block incoming connections for the wireless display feature. If searching for devices doesn't yield any results, temporarily disable your third-party antivirus or add an exception for the "Projecting This PC" service.
Setting up a DLNA server using standard tools
Technology DLNA (Digital Living Network Alliance) allows you to stream media files without screen mirroring, saving computer resources and providing higher image quality. In this case, the TV acts as a client, reading files directly from the computer's hard drive. This is the best way to view photos in a slideshow.
To set this up in Windows, open "Settings" from the Start menu and go to "Network & Internet." Select "Status" and find "Sharing Options." Here, you need to enable network discovery and file and printer sharing. Without these settings, the TV will not be able to see the PC on the local network.
Next, select the folder you want to share. Right-click the desired directory (for example, "Pictures"), select "Properties" → "Sharing" tab → "Share." In the window that opens, add the user "Everyone" and set the permission level to "Read." This will allow the TV to read files, but not modify or delete them.
| Setting parameter | Recommended value | Impact on work |
|---|---|---|
| Network profile | Private network | Opens ports for local exchange |
| Network discovery | Included | Makes your PC visible to TV |
| Password protection | Disabled (for home network) | Makes it easy to connect without entering credentials |
| Multimedia stream | Included | Allows the transfer of photos and videos |
After setup, go to the "Media," "Photo," or "Gallery" section on your TV. Your computer should appear in the list of sources. When you first connect, the TV may ask for permission to connect—confirm it with the remote. Now you can manage folders and open images in the TV's native interface.
☑️ Check DLNA settings
Third-party programs for advanced features
Windows' built-in tools sometimes become unstable or don't support certain file formats. In such cases, specialized media server programs come to the rescue. Universal Media Server, Plex or Kodi provide more flexible settings for transcoding and cataloging content.
The most popular solution is PlexAfter installing the server part on your computer and the client app on your TV (if available in the TV app store), you gain access to a beautiful interface with covers and descriptions. The program automatically indexes your photo library, grouping them by shooting date or geolocation.
- 🚀 Performance: Third-party servers handle large files better using hardware acceleration.
- 🎨 Interface: The visual interface on TV is usually more modern and user-friendly than the standard one.
- 📱 Control: Possibility to control playback from a smartphone via a proprietary application.
When using third-party software, it's important to configure library paths correctly. Make sure photo folders are added to the program's library and have the appropriate content type (Photos/Pictures). Incorrect classification may cause the server to attempt to apply video codecs to photos, causing playback errors.
Why might Plex not be able to see files?
If Plex isn't displaying your photos, check the folder permissions in Windows security settings. The account running Plex (often Local System or a dedicated Plex user) must have read permissions. Also, make sure your antivirus isn't blocking the plexmediaserver.exe process.
Broadcasting via Google Chrome browser
If you don't have a Smart TV or the built-in features don't work correctly, you can use a browser Google Chrome and technology Chromecast built-inThis method is universal and works on most modern Cast-enabled TVs, as well as devices with Chromecast or Android TV boxes.
Open the Chrome browser on your computer and click the three dots in the upper-right corner of the menu. Select "Cast." A list of available devices will appear in the window that opens. Before starting the cast, click the "Sources" button and select "Cast Desktop" or "Cast File," if available in your browser.
This method is convenient because it doesn't require complex network configuration or sharing. However, image quality may be lower than with a direct DLNA connection, as the video stream is compressed in real time. This isn't a problem for static images, but with active cursor use, a noticeable delay may occur.
⚠️ Attention: When casting a browser tab, the audio from your computer is also transmitted to the TV. If you're only showing photos, be sure to lower the volume on your PC or in the tab's settings to avoid background noise.
Troubleshooting connection issues
Even with proper setup, situations may arise where devices stop seeing each other or the streaming is interrupted. Most often, the problem lies in Windows power saving settings. The system may disable the network adapter to save power, which interrupts the connection to the TV.
To fix this, open Device Manager, locate your Wi-Fi adapter, go to Properties → Power Management, and uncheck "Allow the computer to turn off this device." This will ensure stable network operation even during periods of inactivity.
Another common cause is using a guest Wi-Fi network. On guest networks, client isolation is enabled by default, preventing any devices within the network from communicating with each other. Make sure you're connected to your main home network, not the guest network.
Frequently Asked Questions (FAQ)
Why doesn't the TV see the computer even though both are connected to Wi-Fi?
The most likely cause is different network profiles. Make sure the network in Windows is marked as "Private" and not "Public." Also, check if your antivirus or firewall is blocking the connection to the local network.
Is it possible to transfer photos to a TV without a router (Wi-Fi Direct)?
Yes, many modern TVs support Wi-Fi Direct technology. This allows the computer to connect directly to the TV's Wi-Fi signal, bypassing the router. However, the transfer speed may be lower, and control may be less convenient.
What image format is best for TV?
The standard and most compatible format is JPEG. HEIC (from iPhone) or RAW formats may not be supported by TVs' built-in players, so it's best to convert them first or use media servers like Plex, which can transcode images on the fly.
Does the internet affect the speed of photo transfer over Wi-Fi?
No, using DLNA or Miracast within your home network doesn't require an internet connection. Data is transferred locally between the router and devices. Speed depends only on the power of your Wi-Fi router and the distance to it.
