Looking for the perfect 4K HDR sample to push your home theater to its limits? To truly test a high-end display, you need a high-bitrate file that doesn't just look "good" but captures the technical extremes of color, contrast, and motion.

This classic demo features slow-panning shots of intricate textures (wood grain, campfire sparks). It’s perfect for checking if your player can handle high-bitrate playback without stuttering. Where to Find High-Quality Samples

Here are the top recommended 4K HDR samples in MKV format.

  1. "Samsung HDR Demo - Dark" (Best for testing Black Levels/Contrast)
  2. "Sony HDR Demo - Colorful Journey" (Best for testing Color Volume)
  3. "LG OLED HDR Demo - Orbit" (Best for testing motion and upscaling)
  4. "Blade Runner 2049 - Opening Scene" (Often used as a real-world movie sample because of its high bitrate and visual complexity).

Demolandia: Provides a variety of 4K UHD demo files specifically for testing display limits, including dedicated MKV sections.

Dolby Vision Note: While MKV supports Dolby Vision, some older hardware players may only trigger the HDR layer if the file is in an MP4 container. Check your device's compatibility if Dolby Vision doesn't activate.

To view the sample as intended, you need a proper renderer:

  • Jellyfish: Tests motion handling and color gradients.
  • Landscape: Tests fine detail and high dynamic range highlights.
  • Skywalker: A classic demo used by Dolby to show off contrast.

3. Samsung Wonderland (4K HDR10+)

  • Why it’s great – Vibrant colors, fast motion (riding a bicycle through colorful sets), and strong specular highlights.
  • Note – HDR10+ supported only on select devices (falls back to HDR10).
