Why Is HDR Dark? 🕯️ Tone Mapping & Peak Brightness Stress Test

Описание: Is your expensive OLED or Mini-LED TV really showing full HDR detail — or is it clipping bright highlights into white blobs?

Use this professional HDR Peak Brightness & Tone Mapping Test to evaluate how accurately your display handles real HDR10 content.

⚠️ IMPORTANT — READ THIS FIRST
This video is encoded in native HDR10 (ST.2084 PQ).
• Watch only on an HDR-compatible TV, monitor, or smartphone.
• If viewed on an SDR screen, the image will look washed out or gray. This is normal.

🔬 WHAT IS TONE MAPPING?
Movies and HDR games are mastered at 1000, 4000, or even 10,000 Nits.
Most TVs can only display 600–1000 Nits.
Tone Mapping is how your TV compresses this brightness range to fit its panel.

Bad tone mapping:
• Bright clouds, sun, fire, or reflections become pure white
• Detail is lost (HDR Clipping)

Good tone mapping:
• Bright objects stay detailed
• Highlights roll off smoothly
• Real HDR depth is preserved
