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: 2026-10-10.

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

Price comparison: $573.75 to $956.25 (±25% of this product’s price).

Best for: Esports and very high-FPS PC gaming

Think twice if: You prioritize 4K desktop detail or mostly static office work

Plus points
  • 480Hz native refresh for very high-frame-rate play
  • Near-instant OLED pixel response and deep blacks
  • HDMI 2.1 and broad VRR support
Keep in mind
  • 1440p is less detailed than 4K for desktop work
  • OLED burn-in remains a consideration for static-heavy use
  • Text clarity is not its strongest office trait

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 peak brightness
400 nits

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

Tom's HardwareRead the test ↗

HDR highlights

Higher = brighter highlights
HDR peak
709 nits25% window

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

Lower ΔE = less error
Grayscale error · ΔE
4.35 DeltaEDefault
Grayscale error · ΔE
0.53 DeltaECalibrated
Grayscale error · ΔE
2.87 DeltaEsRGB Cal

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

One independently tested sample; lab settings and methods affect results.

Tom's HardwareRead the test ↗

Color range

Coverage and volume differ
DCI-P3 coverage
>97%

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.

Tom's HardwareRead the test ↗

Motion & delay

Lower time = faster
Screen draw time
2 ms480Hz
Total input lag
15 ms480Hz

Pixel response affects moving edges. Input lag is delay before the image starts changing; screen draw and signal processing are separate tests. Compare like-for-like methods.

Total control lag includes more than signal processing. Compare it with the same timing method.

Tom's HardwareRead the test ↗

Screen consistency

Lower variation = more even
Brightness variation
2.4%

Variation shows how much brightness or dark-screen appearance differs across the panel. Check the test pattern and any uniformity setting before comparing results.

One incentivized Best Buy review is separate from fourteen manufacturer-syndicated ASUS reviews; those fourteen are excluded from the independent pool.

Anti-flicker modes reduce flicker under changing frame rates but have operating trade-offs; this is not a long-term failure-rate test.

Tom’s Hardware measured 709 nits using a 25% HDR window; SDR peak was 400 nits. Different window sizes must not be treated as directly equivalent.
