Peak brightness nits, local dimming algorithms, and "blooming" (light bleeding into dark areas).
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.
Do not download sample files from sketchy third-party sites that bundle malware with video files. Use these reputable, dedicated repositories:
Look for true 3840 × 2160 (UHD) resolution. Standard 24fps content is fine for movies, but for testing motion handling and decoder weaknesses, look for 4K at 60fps . High frame rate files will reveal issues like screen judder, interpolation artifacts, or dropped frames that might not show up during slower films.
LG's official OLED demonstration clips are legendary for a reason. They feature pure black backgrounds peppered with explosive, highly saturated colors.
