TVs support different USB video and audio formats depending on the exact model and year. A file’s extension—such as MP4 or MKV—does not tell you whether it will play: the TV must support the container, the video and audio codecs inside it, and the file’s technical settings. Check your model’s official USB playback guide before converting files or buying storage.
Why one USB video file plays and another does not
A media file has several compatibility layers. The container (for example, MP4, MKV, or AVI) packages the video and audio streams; those streams use separate codecs. The TV also has limits for settings such as resolution, frame rate, bitrate, and sometimes codec profile or level. It needs to support the combination, not merely recognize the filename extension.

That is why changing .mkv to .mp4 does not convert a file. If the video or soundtrack uses an unsupported codec, the renamed file still contains the same media streams. LG notes that playback can fail when a video’s codec specifications do not match the TV’s requirements; Samsung publishes separate tables for containers, codecs, and technical limits. See LG’s USB video codec guidance and Samsung’s media specifications overview.

Manufacturer tables include familiar containers such as MP4, MKV, AVI, MOV, and MPEG, but the lists are specific to particular models or generations. For example, Samsung’s 2026 TV video specifications list containers including AVI, MKV, ASF, MP4, MOV, 3GP, MPG/MPEG, TS, FLV, VOB, M2TS, and WebM. That page also lists video codecs such as H.264, HEVC/H.265, MPEG-2, AV1, VP9, and VP8, with support and technical limits varying by model class.

These examples are not a universal Samsung compatibility promise, and they do not describe every Samsung TV. LG’s published tables likewise cover specified generations and include formats such as ASF/WMV, AVI, MP4/M4V/MOV, MKV, TS, MPG/MPEG, and VOB, with codec support varying by model. Use the list for your exact set rather than treating a brand-wide or extension-only list as definitive.
Check audio separately from video
A TV may recognize a video stream but fail to decode its soundtrack. Look up the audio codec as well as the video codec in the model’s USB playback table. Samsung’s 2026 specifications list audio formats including AC3, LPCM, AAC, HE-AAC, DD+, MP3, MPEG-H, AC-4, Opus, G.711, and Vorbis in the relevant tables; they also state that DTS audio is not supported on 2026 TVs. These entries and limits are tied to that specification, not all Samsung models or other brands.

LG’s tables also identify audio support by container and generation. Sony’s general codec overview offers broad examples for Android TV and Google TV, but directs owners to the Help Guide for their individual TV. Sony’s older USB tables cover particular model families and warn that not every file is guaranteed to play. See Sony’s Android TV and Google TV format overview and Sony’s USB compatibility tables.
How to check whether your file will play
- Identify the TV precisely. Find its full model number and year in the settings, on the product label, or in its manual.
- Open the official guide for that model. Find the USB media playback table on the manufacturer’s support page or in the Help Guide. Check that the table covers your model or its generation.
- Inspect the file’s actual media details. On a computer, use a reputable media-information utility to identify its container, video codec, audio codec, resolution, frame rate, and bitrate. The filename extension alone cannot provide all of these details.
- Compare every relevant field. Check the TV’s limits for both codecs and for resolution, frame rate, bitrate, and any listed codec profile or level.
- Check the USB drive separately. Confirm that the TV supports the drive and its file system, and follow the model guide’s connection and formatting instructions.
- Use a comparison file to narrow down a failure. If other files play, compare their media details with the file that fails. If a codec or parameter is unsupported, re-encoding to a combination listed for the TV may help; renaming the extension will not.
If the TV does not recognize the USB drive
Drive recognition is separate from media decoding. A TV can support a file’s codecs but still fail to see the storage because of the drive, connection, or file system. Check the exact model guide for supported USB devices and file systems. If the drive is not detected, verify on a computer that it works and confirm that it follows the TV maker’s connection and format instructions before changing its format.

What to compare when choosing a file or TV
A useful compatibility check includes the TV model and year, container, video codec and profile, audio codec, resolution, frame rate, bitrate, and USB device and file-system support. A short list of extensions cannot establish that a particular file will play.
