Method 1. Enable Game Mode

If you're playing games on Samsung TV rather than watching videos, you're still prone to encounter video lagging behind audio issue. When it comes to game playing, the most common issue is called input lag. In a nutshell, input lag is a symptom of the same problem as lip-sync errors: the TV's slow processing results in a delay in loading the video image to the screen.

In such case, find and enable Game mode on your Samsung TV, which deactivates most of this processing and renders the video to your eyeballs sooner. The downside of game mode is that it would degrade picture quality to certain degree. But all in all, it's worth a try for lip-sync error.

Part 3. How to Fix Audio Out of Sync caused by Unsupported Video Formats/Codecs?

The Key: Transcode videos to Samsung TV-compatible formats.

Winxvideo AI is an excellent 4K video converter which can convert MKV to MP4, MOV, AVI, WebM, and 420+ profiles, transcodes HEVC MKV to H.264, DTS to MP3/AAC, and changes MKV video specifications like resolution (eg. 4K to 1080p), bit rate, frame rate, etc. for Samsung TV.

Step 1. Open the video converter after downloading and installation, and load the Samsung TV unrecognized video files through drag and drop, or "+ Video" button. Batch conversion is available when you imported multiple videos at once.

Step 2. Seconds later, an output profile window pops up automatically. Scroll down to choose "General Profiles" > "MP4 Video" > "OK". Of course, if you're clear which codec is the culprit, for example, mkv file audio not supported on TV, you can transcode the embedded codec without changing video container, for example, go to "PC General Profiles" > Matroska Video (h.264+aac) to transocde MKV HEVC to H.264, and DTS to AAC.
