How these scores work

The Piqelo Score is our published assessment of this exact product, including value. Your search does not change it. The Search Score uses the underlying research, your preferences and comparison with similarly priced products. Value is counted once; budget and required features are hard limits.

Product score published: 2026-10-08.

The match remains an estimate while supporting research is checked. It is not a new final product score.

Price comparison: $1,125.00 to $1,874.98 (±25% of this product’s price). Comparable evidence is limited.

Exact-model findings and measurements

Trade-off · hdr image

TechSpot measured about 1,200 nits at a 2% HDR window with Peak Brightness High, versus a 600–650-nit peak range on Low. High boosts the whole dark scene’s EOTF rather than just extending highlight headroom.
