How to watch video from your phone on TV via a USB cable on Android: a complete guide

Have you downloaded a movie to your phone, but want to watch it on the big screen? Connecting via a USB cable is one of the most stable ways to transfer video from a Androiddevice to a TV, especially if you don’t have Wi-Fi or Smart TV. However, not everyone knows that this requires not only a physical connection, but also the correct settings on both devices.

In this article we will examine three proven methods video playback via USB: from simple connection as a flash drive to using special data transfer modes. You will learn what formats are supported by most TVs, how to avoid file reading errors, and what to do if the TV does not see your smartphone. And also - why some LG and Samsung TVs block access to USB drives from phones without additional settings.

Important: if your TV was released before 2015, it may not support modern video formats (for example, MKV s codec H.265). In this case, file conversion will be required - we will also talk about this below.

1. Preparing your phone and TV: what you need to check before connecting

Before connecting the devices with a cable, make sure that both of them are ready for use. Start with your phone:

• 📱 Android version: On older smartphones Android 6.0 the mode may not work File transfer (MTP). Update the system in Settings → System → Software update.
• 🔌 USB cable type: Use the original cable from the phone or a certified one USB Type-C/USB-A (for older TVs it may be necessary adapter). Cheap cables often do not support data transfer.
• 📁 File format: TVs usually read MP4, AVI, MKV (with limitations), but can ignore MOV or FLV. Check the specifications of your TV model.

Now about the TV:

• 📺 USB port: Make sure the port is working (connect a USB flash drive for the test). On some models Sony Bravia and Philips USB ports are marked as Service Only —they are not suitable.
• 🔧 Input settings: Switch the signal source to USB in the TV menu (usually the button Source or Input on the remote control).
• 📂 File system: TVs read FAT32 i exFAT, but not NTFS. If your phone is formatted in NTFS, you will have to use a different connection method.

⚠️ Attention: On TVs Samsung series J i K (2015-2017) you may need to enable USB Debugging mode in your phone's developer settings, even for simple video playback. This is due to limitations of the TV firmware.

2. Method 1: Connecting your phone as a USB drive (MTP)

This is the most universal method that works on 90% of TVs with a USB port. Your phone will be detected as an external drive, and the video can be opened through the TV's built-in media player.

Step-by-step guide:

1. Connect your phone to the TV with a cable. A notification will appear on the smartphone screen Charging via USB.
2. Tap on the notification and select File transfer (or MTP — Media Transfer Protocol).
3. On the TV, open the signal source menu (Input or Source) and select USB.
4. In the TV file manager, find the video folder (usually DCIM, Movies or Download).

If the TV does not see the files:

• 🔄 Reboot both devices and repeat the connection.
• 📌 Try another USB port on the TV (if there are several of them).
• 📱 On the phone in the settings For developers enable USB debugging (sometimes helps with MTP blocking).

⚠️ Attention: On phones Xiaomi, Huawei i OnePlus the function may be enabled by default Fast charging, which blocks data transfer. Disable it in the battery settings.

3. Method 2: Using an OTG adapter for old TVs

If your TV is not supports MTP (for example, models before 2014), but it has a USB port, you can use OTG adapter. This method converts the phone into a host device, allowing you to connect flash drives or hard drives to it. However, playing video on TV will require an additional step.

What you will need:

• 🔌 OTG adapter (for example, USB-C to USB-A for modern phones).
• 💾 Flash drive or external a hard drive formatted in FAT32.
• 📱 An application for managing files (for example, FX File Explorer or Solid Explorer).

How it works:

1. Copy the video from your phone to a flash drive via an OTG adapter.
2. Disconnect the adapter from the phone and connect the flash drive directly to the TV.
3. Select the USB input on the TV and play the video.

TV model	MTP support	Support OTG	Max. file size
Samsung QLED (2020–2023)	Yes	Yes (via adapter)	4 GB (FAT32)
LG OLED (2018–2023)	Yes (with update)	No	8 GB (exFAT)
Sony Bravia (2016–2022)	Yes	Yes	16 GB (NTFS not supported)
Philips (up to 2017)	No	Yes (FAT32 only)	2 GB

4. Method 3: Direct playback via HDMI adapter (for modern phones)

If your phone supports USB-C with video output (for example, Samsung Galaxy S22, Google Pixel 6 or OnePlus 10 Pro), can be used HDMI adapter to directly broadcast the screen to a TV. This will allow you not only to watch video, but also to control playback from your phone.

Required. equipment:

• 🔌 USB-C to HDMI adapter (for example, from Anker or Baseus).
• 📺 HDMI cable (usually included with the adapter).
• 🔋 Power supply for the phone (the adapter consumes a lot of energy).

How to connect:

1. Connect the adapter to the phone and the HDMI cable to the TV.
2. On TV, select the signal source HDMI.
3. On the phone you may be asked for image output resolution - confirm.
4. Start the video - it will be duplicated on the TV screen.

Advantages of the method:

• ⚡ Instant synchronization without delays.
• 🎮 Ability to control playback from your phone.
• 🔊 Audio transmission via HDMI (no need for separate speakers).

⚠️ Attention: On phones Xiaomi i POCO when you first connect the HDMI adapter, you may need to enable the mode External display in the screen settings (Settings → Display → HDMI mode).

Why doesn't sound work via HDMI?

If the sound is not transmitted to the TV, check:

1. In the phone settings, audio output via HDMI is selected (Settings → Sound → Audio output).

2. The cable and adapter support audio transmission (cheap adapters often transmit only video).

3. On the TV, the HDMI input is not disabled in the sound menu.

5. What video formats are supported by TVs?

Even if you have connected your phone correctly, the TV may not play the video due to an incompatible format. Here is a table of supported formats for popular brands:

TV Brand	Supported formats	Max resolution	Supported codecs
Samsung	MP4, MKV, AVI, TS	4K (3840×2160)	H.264, H.265 (HEVC), MPEG-4
LG	MP4, MOV, WMV	4K (2019+ models only)	H.264, VP9, MPEG-2
Sony	MP4, MKV, AVI, M4V	4K HDR	H.264, H.265, Xvid
Philips	MP4, AVI, MPG	Full HD (1920×1080)	H.264, MPEG-2, DivX

If your video is in an incompatible format, use converters:

• 🎬 HandBrake (free, supports H.265 → H.264).
• 📱 Video Converter Android (for conversion directly on your phone).
• 💻 VLC Media Player (can transcode files without loss of quality).

6. Solving problems: the TV does not see the phone or video

Even with the correct connection, errors may occur. Here are the most common ones and how to fix them:

Problem 1: The TV does not respond to the USB connection

• 🔌 Check cable: try to charge the phone - if charging occurs, but data is not transferred, the cable is faulty.
• 📱 On the phone in the settings USB select File transfer (not Charging only).
• 📺 Reboot the TV: sometimes the USB port freezes after the previous connection.

Problem 2: The video does not play or comes with artifacts

• 🎵 Check the codec: if the video is in MKV s H.265, and TV only supports H.264, recode the file.
• 📁 Make sure that the path to the file does not contain Cyrillic characters (for example, Movie.mp4 may not open).
• 🔊 If there is sound, but no picture, the problem is in the codec. Try playing the video on another device.

Problem 3: The phone does not offer MTP mode

On some phones (for example, Huawei or Oppo) mode MTP hidden. To enable it:

1. Connect the phone to the computer.
2. In the USB notification, select File transfer.
3. Disconnect from the PC and connect to the TV - the mode will remain.

7. Alternative video transfer methods (if USB does not work)

If connecting via USB fails, consider alternatives:

• 📶 Wi-Fi Direct / Miracast: Wireless screen casting (works on Samsung Smart View, LG Screen Share).
• 🌐 DLNA: Streaming via local network (applications BubbleUPnP or Plex).
• ☁️ Cloud services: Upload the video to Google Drive or YouTube (private) and open through the TV browser.
• 💽 External storage: Copy the video to a flash drive and connect it to the TV.

Advantages and disadvantages of alternatives:

Method	Pros	Cons
Wi-Fi Direct	Wireless, high quality	Delays with a weak signal
DLNA	Works on old TVs	Requires router setup
Cloud	Access from any device	Internet speed limit
