3 Simple Ways to Play MKV movies on Samsung Smart TV

Stop guessing which MKV files your Samsung TV will play. Learn 3 simple ways to watch MKV movies via USB, DLNA, or screen mirroring. No matter which of the three methods you try, you'll hit the same wall—your Samsung TV just won't play those MKV files. That's exactly why you need a solid converter to transcode MKV into a format that works everywhere. And honestly, Acrok Video Converter Ultimate is the clear winner.

You've downloaded a great MKV movie, plugged your USB drive into your Samsung Smart TV, and… nothing. The file shows up but won't play. Or worse, the TV doesn't even recognize it.

If this sounds familiar, you're not alone. Many Samsung TV owners face this exact issue. The good news? There are three simple ways to solve it—and you don't need to be a tech expert to do any of them.

Before we dive into the methods, let's understand why this happens in the first place.

Why Won't My Samsung TV Play MKV Files?

Here's the key thing to understand: MKV is just a container—think of it like a box that holds video, audio, and subtitle tracks together. The box itself isn't the problem. What's inside the box—the video and audio codecs—determines whether your Samsung TV can play it.

Samsung Smart TVs do support MKV files. According to Samsung's official specifications, supported containers include MKV, MP4, AVI, MOV, 3GP, ASF, and more. However, Samsung TVs only recognize MKV files that use specific codec combinations. The HEVC (H.265) codec, for example, is only supported within MKV, MP4, and TS containers. If your MKV file uses unsupported video or audio codecs—like DivX or DTS on newer models—your Samsung TV simply won't play it.

Common symptoms include:

• A blank black screen when you try to play the file
• Only audio plays while video fails to show up
• The TV displays a "file format not supported" error
• The file doesn't appear in the USB menu at all

What Video Formats Does Samsung TV Support via USB?

Samsung Smart TVs support a wide range of video formats via USB, including AVI, MKV, ASF, MP4, 3GPP, VRO, VOB, PS, and TS. The TV supports USB drives formatted with FAT, exFAT, and NTFS file systems.

However, even with supported containers like MKV, playback depends entirely on the codecs used inside. For optimal compatibility, Samsung TVs generally support:

The best video format for Samsung TV USB playback is typically MP4 with H.264 video codec and AAC audio codec—this combination offers the broadest compatibility across virtually all Samsung TV models, from older LED units to the latest QLED and OLED screens.

Now, let's look at three simple ways to play MKV files on your Samsung Smart TV.

Method 1: Play MKV on Samsung Smart TV via USB Drive

This is the most straightforward method. If your Samsung TV has a USB port (most models do), you can transfer MKV files to a USB drive and plug it directly into the TV.

Step-by-Step Guide:

Step 1: Prepare Your USB Drive

Make sure your USB drive is formatted with a file system your Samsung TV supports—FAT32, exFAT, or NTFS. For files larger than 4GB, you'll need to use exFAT or NTFS, as FAT32 has a 4GB file size limit.

Step 2: Copy MKV Files to the USB Drive

Transfer your MKV movies to the USB drive. Keep file names short and avoid special characters—this can sometimes cause playback issues.

Step 3: Connect the USB Drive to Your Samsung TV

Insert the USB drive into the USB port on your Samsung TV (usually located on the side or back of the device).

Step 4: Open the Media Player

Using your TV remote, press the Source or Media button and select USB or Media Player. The TV will automatically scan for compatible files.

Step 5: Select and Play Your MKV File

Navigate to the folder containing your MKV file and select it to start playing.

Limitations of USB Playback

• Not all MKV files will play—only those with Samsung TV USB supported video format codecs
• The TV can display up to 1,000 files per folder
• Some USB devices may not be compatible with the TV
• DivX and DTS codecs are not supported on Samsung TV models released in 2021 and later
• HEVC codec is only available in MKV/MP4/TS containers

What If Your MKV File Won't Play?

If your MKV file won't play via USB, it's almost certainly a codec compatibility issue. The most reliable solution is to convert the MKV file to a format your Samsung TV fully supports—which leads us to Method 3 (the recommended approach).

Method 2: Play MKV on Samsung Smart TV via DLNA Streaming

DLNA (Digital Living Network Alliance) allows you to stream media from your computer or mobile device to your Samsung TV over your home Wi-Fi network. This method eliminates the need for a USB drive altogether.

Step-by-Step Guide:

Step 1: Connect Devices to the Same Wi-Fi Network

Make sure both your Samsung TV and the device containing the MKV file (computer, laptop, or NAS) are connected to the same Wi-Fi network.

Step 2: Set Up a DLNA Media Server on Your Computer

You'll need DLNA server software on your computer. Popular options include:

• Plex – A full-featured media server with excellent MKV support
• Windows Media Player – Built into Windows, with built-in DLNA streaming capabilities
• Serviio – A lightweight DLNA server that works well with Samsung TVs
• AllShare Play – Samsung's own DLNA software, recommended for best compatibility

Step 3: Enable DLNA on Your Samsung TV

On your TV remote, press the Source or Media button and select DLNA or AllShare. The TV will search for compatible DLNA devices on your network.

Step 4: Select Your Device and Play the MKV File

Once your computer appears in the list, select it, navigate to the folder containing your MKV file, and start playing.

Limitations of DLNA Streaming

• Network speed matters—Wi-Fi congestion can cause buffering or stuttering

• Codec compatibility still applies—even via DLNA, your Samsung TV will only play MKV files with supported codecs

• Not all DLNA servers are created equal—some may not transcode MKV files properly for Samsung TVs

• Requires both devices to remain powered on and connected to the same network

Pro Tip: Use a Media Server with Transcoding

Some DLNA servers like Plex can transcode MKV files on the fly—converting the video to a Samsung-friendly format in real-time as it streams. This means you don't need to convert the file beforehand, but it requires a reasonably powerful computer to handle the transcoding.

Method 3: Screen Mirroring from Phone or Tablet

If you have an MKV file stored on your smartphone or tablet, you can mirror your device's screen directly to your Samsung TV. This method uses Samsung's Smart View or SmartThings app.

Step-by-Step Guide:

Step 1: Connect Both Devices to the Same Wi-Fi Network

Ensure your phone/tablet and Samsung TV are connected to the same Wi-Fi network.

Step 2: Download the SmartThings App

Download and install the SmartThings app on your mobile device from the Google Play Store or Apple App Store.

Step 3: Enable Screen Mirroring

• On Android (Samsung phones): Swipe down from the top of the screen to open the Quick Settings panel, then tap the Smart View icon. Select your Samsung TV from the list of available devices.
• On Other Android devices: Open the SmartThings app, tap the menu icon (three horizontal lines), then select Mirror Screen (Smart View).
• On iPhone: Use the Screen Mirroring feature in the Control Center and select your Samsung TV (if AirPlay is supported).

Step 4: Start Mirroring

Tap Start or Begin to start mirroring your phone screen to your TV. Once connected, open any media player app on your phone (like VLC or the default video player) and play the MKV file. The video will appear on your TV screen in real-time.

Limitations of Screen Mirroring

• Video quality depends on your Wi-Fi network—buffering or pixelation can occur on slower networks
• Audio sync issues may arise depending on the connection quality
• Not all apps support full-screen playback when mirrored
• Requires your phone to stay on and powered during playback
• MKV codec compatibility still matters—if your phone can't play the MKV file, mirroring won't help

Alternative: Tap View

For Samsung phone users, Tap View offers an even simpler option—just tap your phone against your Samsung TV to start mirroring instantly. Make sure your SmartThings app is updated to version 1.7.45 or later.
