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.

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

Price comparison: $824.25 to $1,373.75 (±25% of this product’s price). Comparable evidence is limited.

Decision snapshot

Extreme refresh OLED

Best for: Competitive PC gaming where motion clarity matters more than 4K detail

Think twice if: You need 4K desktop detail, USB-C docking or dislike glossy reflections

PC gamingMixed use
Plus points
  • Native 1440p 540Hz plus a 720Hz boost mode
  • Near-instant OLED response supports very sharp high-FPS motion
  • Bright Tandem OLED combines deep blacks with stronger highlight output
Keep in mind
  • The 720Hz boost mode reduces resolution to 720p
  • Glossy coating can show distracting mirror-like reflections
  • OLED static-content care remains relevant for desktop-heavy 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.

Everyday brightness

Higher = brighter
SDR brightness

SDR brightness

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.

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.

From evidence to Piqelo Rating

What is still needed for a Piqelo Rating

Expert 50% · Owners 25% · Reliability 15% · Value 10%. The rating appears when all four components are supported.

Expert performance
5 eligible test sources collected. Performance calibration is still required.
Owner experience
At least 30 eligible exact-model owner reviews are needed; 27 are currently available.
Reliability
A supported reliability calculation needs model maturity, recurring risks and eligible owner evidence.
Current value
A current US price is available. Comparison with a supported peer group is still required.

Exact-model findings and measurements

Supported finding · motion response

TechSpot measured pixel transitions around 0.2–0.3ms across refresh rates. These lab results are distinct from the manufacturer’s 0.02ms claim; maximum motion clarity still depends on achieved game frame rate.

Supported finding · input latency

TechSpot measured approximately 0.1ms processing delay in the 540Hz and 720Hz modes, in both SDR and HDR. This processing-delay figure does not include the complete input-to-photon pipeline.

Supported finding · hdr image

At a 2% HDR window, default modes peaked around 600 nits. Enabling Adjustable HDR at brightness 100 raised Gaming/Cinema/Console modes to around 1,350 nits with some overbrightening.

Supported finding · sdr image

With Uniform Brightness disabled, Tom’s Hardware measured more than 544 nits SDR using a 25% window. Full-field output was approximately 360 nits. Retaining window size prevents the smaller-window result from being presented as sustained desktop brightness.

Trade-off · color accuracy

The PG27AQWP-W review measured calibrated grayscale error of 0.97 ΔE and gamma 2.18 against a 2.2 reference. Its uncalibrated sample showed a visible warm grayscale tint. These grayscale results are separate from color-gamut error.
