Owners of modern technology often face the need to stream content from a small screen to a large one. Laptop Acer and TV Samsung — a popular combination that allows you to transform your living room into a multimedia center. To achieve this, you don't need long HDMI cables, as modern wireless standards allow for wireless transmission of high-definition video.
There are several proven methods for synchronizing devices, each with its own features and use cases. In this article, we'll cover in detail how to set up a connection, what technologies are used, and what to do if devices can't see each other. You'll learn about built-in Windows features and specialized Samsung apps that significantly simplify the process.
Before starting the setup, make sure both devices are turned on and in good working order. The key condition A successful connection requires the laptop and TV to be on the same local network. This means they must be connected to the same router, either via cable or Wi-Fi.
Wireless image transmission technologies
Before moving on to practical steps, it's important to understand the specific protocols involved. The primary standard for wirelessly transmitting a video stream from a laptop screen to a TV is the Streaming technology. MiracastIt is built directly into the Windows operating system and is supported by most modern Smart TVs.
The second popular method is to use a protocol DLNA, which allows you to stream media content (video files, photos, music) through dedicated apps. Unlike Miracast, which mirrors the entire desktop, DLNA is focused on playing specific files. Also worth mentioning are proprietary solutions from Samsung, such as Smart View, which optimize the connection for devices of this brand.
It's worth noting that data transfer quality directly depends on the speed of your Wi-Fi router. If you plan to watch 4K video, make sure your equipment supports the standard. 802.11ac or newer.
⚠️ Warning: When using guest Wi-Fi mode in public places or offices, broadcasting may be blocked by the router's security settings, since the devices are located in isolated network segments.
The differences between these methods are significant: Miracast creates a direct connection for screen mirroring, while DLNA uses the network to stream files. The choice of method depends on your end goal: showing a presentation or playing a movie.
Preparing equipment and network
The success of the operation is 90% dependent on proper preliminary preparation. The first step is to ensure that the TV Samsung The Smart TV function is activated and it is connected to the Internet. The TV menu usually has a section Net or Network, where the connection status is displayed.
On a laptop Acer The Wi-Fi adapter must also be activated. Even if the laptop is connected to the router via an Ethernet cable and the TV has Wi-Fi, they will still be on the same network. However, for Miracast technology, it's preferable for both devices to use a wireless channel or be on the same subnet.
- 📶 Make sure both devices are connected to the same Wi-Fi network (SSID).
- 🔄 Check that the function for receiving external connections (often called "Mircaste" or "Connection Guide") is enabled on your TV.
- 💻 On your laptop, update the wireless adapter drivers through Device Manager.
- 🔌 Restart your router if the connection is unstable or devices take a long time to find each other.
Some Samsung TV models require manual permission to connect external devices. To do this, go to the menu and find the option List of external devices, then select Connection Manager and make sure the notification option is turned on.
Method 1: Using Windows' built-in feature (Miracast)
The fastest way to display an image is to use the built-in tools of the Windows 10 or 11 operating system. This method doesn't require installing additional software and works at the driver level. Miracast technology allows for real-time image streaming with minimal latency.
To start, press the key combination Win + K on your laptop's keyboard Acer. The "Connect" sidebar will appear on the right, where the system will begin searching for available wireless displays. If the TV Samsung turned on and ready to receive a signal, its name will appear in the list.
After selecting the TV, a connection permission prompt may appear on the TV screen. Use the remote control to press "Accept" or "Allow." After a few seconds, the image from your laptop desktop will appear on the big screen.
⚠️ Important: If your TV doesn't appear in the list of available devices, check your Windows Firewall settings. Your network profile must be set to "Private," not "Public," to allow device discovery.
Projection modes are controlled via the menu. ProjectYou can choose to duplicate (screen copy), extend (second monitor), or display only on the second screen. To change the resolution or orientation, use the standard Windows display settings.

Method 2: Samsung Smart View app and DLNA
If the standard Windows connection is unstable or you only need to stream specific files, it's best to use specialized software. Samsung offers an app Smart View, which was previously available for PCs, but its functionality is now often integrated into the browser or replaced by standard Windows tools. However, the built-in Windows player can be used to stream media files.
Open a folder with videos or photos on your laptop, right-click on the file and select Transfer to device (Cast to Device). Select your TV from the list. SamsungThe file will begin buffering and playing on the TV, while the laptop can be used for other tasks.
This method is especially convenient when you need to show photos to guests or play a movie without expanding your browser window to fill the entire screen. The DLNA protocol ensures good image quality because the file is streamed rather than compressed in real time, as with screen mirroring.
| Parameter | Miracast (Projection) | DLNA (Media) |
|---|---|---|
| Transmission type | Full screen in real time | Separate files |
| CPU load | High | Low |
| Using a laptop | Limited (all actions visible) | Free |
| Quality | Depends on Wi-Fi signal | Original file quality |
It's important to understand that when using DLNA, the laptop acts as a server. If you turn off the laptop or close the source app, playback on the TV will be interrupted.
What to do if the sound comes through the laptop speakers?
If the picture is on the TV but the sound remains on the laptop, click the speaker icon in the Windows tray (lower right corner). Select your Samsung TV from the list of playback devices. If it's not listed, right-click an empty space in the sound window and select "Show disabled devices."
Setting up display and sound options
Once the connection is successful, it's important to configure the output settings for comfortable viewing.
