Modern technologies make it possible to stream content from a smartphone to a big screen even without internet access or a router. Users often wonder how to connect a Samsung phone to a Samsung TV without Wi-Fi or wires to view photos or play videos. This is entirely possible if you know what hidden features and hardware interfaces can be used.
The main principle of operation in such cases is based on technology Wi-Fi Direct or a physical connection via a USB port. In the first case, the devices create their own local network for data transfer, eliminating the need for an external router. In the second case, the signal is transmitted via a cable, ensuring maximum stability and image quality without lag.
In this guide, we'll cover all available methods, from built-in software solutions to using special adapters. You'll learn how to activate Miracast on different versions of the operating system and which cables are best suited for transmitting high-definition video signals.

- 🔒 When connecting for the first time, you may be asked to enter the PIN code displayed on the TV screen.
Connection quality directly depends on the distance between the devices and the presence of physical obstacles. For best results, try to be in the same room and not block the line of sight between the receiver and transmitter.
In some older TV models the function may be called Miracast or Screen MirroringThe operating principle remains identical: a direct communication channel is created through which a video stream and audio signal are transmitted.
Connection via HDMI cable and adapters
If wireless methods aren't suitable for your needs in terms of quality or stability, a wired connection is the best solution. To connect a Samsung phone to a Samsung TV without Wi-Fi, you can use a special adapter. USB-C to HDMIThis method guarantees the transmission of images in maximum resolution without compression.
You will need the adapter itself that supports the standard. DisplayPort Alt ModeNot all USB-C cables transmit video; many are designed for charging only. When purchasing, pay attention to the specifications: it should support 4K or 1080p video. Connect the adapter to your smartphone, and then plug a regular cable into its HDMI port, with the other end connected to your TV.
After the physical connection is made, switch the signal source on the TV. Press the button Source or Input on the remote control and select the appropriate port, for example, HDMI 1The image should appear automatically. If it doesn't, check the resolution settings in your smartphone's menu.

- 🔌 Use certified cables to avoid damaging the ports.
- 🔋 For long HDMI cables, an active signal amplifier may be required.
- 📐 The cable length should not exceed 5 meters to maintain image quality.
This method is ideal for presentations or watching movies, where every detail and the absence of lag are crucial. A wired connection eliminates any interference from neighboring wireless networks.
Using the Samsung SmartThings app
Ecosystem Samsung offers another powerful tool - an application SmartThingsAlthough it's often associated with internet-based smart home control, it also has the functionality for local connection. This is especially relevant if the standard Smart View method doesn't work for some reason.
The application is pre-installed on most smartphones. GalaxyIf you don't have it, download it from the store. Galaxy Store or Google Play. Launch the program and go to the tab DevicesClick the add new device button (the plus sign in the corner). The system will prompt you to scan a QR code or find a nearby device.
