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: 2026-10-07.

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

Price comparison: $450.00 to $749.98 (±25% of this product’s price). Comparable evidence is limited.

Test results

Image quality, explained

Selected independent measurements, with what they mean in everyday use. Picture mode and test method matter; these results are not additional Piqelo scores.

Everyday brightness

Higher = brighter
SDR brightness
243 nitsSDR; window and full field equivalent

SDR is everyday desktop content. More brightness can help in a lit room; reflections and the size of the bright area still matter.

HDR measures bright highlights in games and video. A small-window peak is different from full-screen brightness, so check the window and mode.

Delta E measures the difference from the target color or gray. A calibrated result describes that setup; it does not establish factory accuracy.

Coverage is how much of a named color space is reproduced. Gamut volume describes its overall extent and can exceed 100%; it is not coverage or accuracy.
