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: $825.00 to $1,374.98 (±25% of this product’s price). Comparable evidence is limited.

Decision snapshot

5K2K OLED ultrawide

Best for: One-screen ultrawide gaming and productivity with high pixel density

Think twice if: You have a shallow desk or prefer a conventional 16:9 layout

PC gamingCreatorOfficeMixed useMac / USB-C
Plus points
  • 5120x2160 delivers much higher work-space density than 3440x1440 ultrawides
  • 165Hz native plus 330Hz dual mode balances detail and speed
  • USB-C 90W and KVM support a full multi-device desk
Keep in mind
  • Large 39-inch curved format needs substantial desk depth
  • The 330Hz mode uses a lower 2560x1080 resolution
  • OLED static-content care remains relevant for productivity use

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.

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

Color accuracy

Lower ΔE = less error
Grayscale error · ΔE
0.7 DeltaEOut of box

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.

Motion & delay

Lower time = faster
Black-to-white response
0.24 ms165Hz; one-inch square · 165Hz

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.

Response, signal processing and total lag are different metrics; do not compare across lab methods.
