Not all 4K files are created equal. A true benchmarking sample must push your hardware to its absolute technical limits. When looking for the best sample files, check for these specifications: 1. True 10-Bit or 12-Bit Color Depth
A low-powered processor or a slow storage drive usually causes stuttering. Move the MKV file to a fast internal SSD or a high-speed USB drive, and close background applications. Audio Desynchronization
While encoding HDR requires complex commands (like specifying -pix_fmt yuv420p10le for 10-bit color), splitting a file (lossless cut) is simple. Use the following command to copy a specific segment directly without quality loss: 4k hdr sample mkv best
When the file begins playing, look for an HDR, HDR10+, or Dolby Vision logo to pop up in the top right-hand corner of your screen. If this logo does not appear, your device is converting the file down to Standard Dynamic Range (SDR), washing out the colors.

However, there is one critical caveat: Dolby Vision. The dynamic metadata that drives Dolby Vision's scene-by-scene color grading often requires an MP4 container for correct playback. Files with the .mkv extension might not properly carry the Dolby Vision layer to your display. Therefore, for a general HDR10 or HDR10+ test, MKV is ideal. For a pure Dolby Vision test, look for .mp4 files.
