ASUS ROG Swift OLED PG27AQWP-W review

A 27-inch 1440p 540Hz tandem WOLED with a glossy TrueBlack coating and some of the highest measured OLED brightness: our competitive OLED pick.

Quick verdict

The PG27AQWP-W is the OLED to buy if competitive shooters come first but you still want a great picture. Its 4th-generation tandem WOLED panel runs 540Hz at 1440p, and TFTCentral measured very high brightness for an OLED: about 381 nits in SDR with Uniform Brightness and roughly 1,800 nits for small HDR highlights. The glossy TrueBlack coating gave the deepest blacks in a lit room of any OLED coating TFTCentral had tested.

The same gloss is its biggest caveat: a window or lamp behind you will reflect like a mirror. The 720Hz mode runs at 1280×720, which reviewers found visibly soft, so treat it as a niche extra rather than a reason to buy.

26.5″ · 1440p · 540Hz · dual mode 720p at 720Hz · WOLED (4th gen, Primary RGB Tandem) · BFI (ELMB)

Buy it if

  • You play competitive shooters and your PC holds well above 240 fps.
  • Your room lighting is controlled and you want the deepest-looking blacks.
  • You want OLED brightness closer to LCD levels in both SDR and HDR.

Skip it if

  • Your desk faces a window or bright lamps; the glossy finish will reflect them. Consider the matte LG 27GX790B-B.
  • You rarely exceed 240 fps; a cheaper 240Hz or 280Hz OLED gives the same picture for less.
  • You need USB-C charging or KVM for a laptop.

Advantages and drawbacks

Advantages

  • 540Hz at 1440p with near-instant OLED response.
  • High measured OLED brightness: about 381 nits SDR with Uniform Brightness, and very bright HDR highlights (TFTCentral).
  • Glossy coating keeps blacks deep in ambient light and makes text and images look crisp.
  • Improved RGWB subpixel layout reduces text fringing versus older WOLED panels.
  • 3-year burn-in warranty and OLED Care Pro with a proximity sensor.

Drawbacks

  • Mirror-like reflections from windows and lamps.
  • No USB-C, power delivery, or KVM.
  • 720Hz mode runs at 1280×720 and looks soft.
  • Wide native color gamut oversaturates SDR content unless you use an accurate mode.

These are third-party results, not our tests. Different outlets use different methods, so compare numbers only within the same source.

Motion, response, and latency

OLED pixels change state almost instantly, so the main limit on motion blur is how long each frame stays on screen. At 540Hz each frame lasts about 1.9 ms on a sample-and-hold display, compared with about 4.2 ms at 240Hz. That is arithmetic, not a measured blur score, and you only get the benefit when your game runs near 540 fps.

ASUS adds ELMB black frame insertion; Tom's Hardware lists it at 120Hz at 1440p and 270Hz in the 720p mode. TFTCentral confirmed a working OLED anti-flicker setting to reduce VRR flicker, which matters on any OLED when frame rates swing.

Image quality and HDR

TFTCentral measured about 381 nits in SDR with Uniform Brightness on (632 nits for small areas without it) and HDR highlights around 1,800 nits in a 1% window in Gaming mode at maximum brightness. Tom's Hardware measured roughly 650 nits at a 25% HDR window. Those are different methods and window sizes, so compare them only within each outlet.

The TrueBlack glossy coating is the defining trait. It has no haze, so images look clear and blacks stay deep in a lit room, but direct light sources reflect clearly. TFTCentral also noted text looks noticeably sharper than older WOLED panels thanks to the corrected subpixel order, though the wide native gamut needs an sRGB mode for accurate desktop color.

Connectivity, PC, and console notes

Ports are one DisplayPort 2.1 at UHBR20, two HDMI 2.1, and a USB hub, with no USB-C. After firmware MCM102, the full 540Hz spec also runs over DisplayPort 1.4 with Display Stream Compression, and UHBR20 GPUs can turn compression off.

Consoles output up to 120Hz, so the 540Hz panel brings no speed advantage there. It will still work with PS5 and Xbox Series X|S over HDMI 2.1, but console-first buyers get more from a 4K model.

Firmware: Firmware MCM102 (November 2025) allows the full 540Hz spec over DisplayPort 1.4 with DSC and lets UHBR20 GPUs disable DSC. TFTCentral updated its review after this release.

OLED care and warranty

OLED Care Pro includes pixel shift, screen saver, panel cleaning, taskbar and logo detection, and the Neo Proximity Sensor that switches the pixels off when you leave. TFTCentral reports a 3-year warranty that includes burn-in. Tandem panels are claimed to last longer than earlier WOLED generations; that is a manufacturer claim, and static desktop use still carries risk.

Warranty: TFTCentral reports a 3-year warranty with burn-in cover, consistent with ASUS's US OLED policy for newer models. Source: ASUS (ROG USA), October 7, 2024, checked September 30, 2026.

Alternatives worth comparing

Questions buyers ask

Does 720Hz mode make games smoother than 540Hz?

Only if your game actually renders above 540 fps, and it drops the resolution to 1280×720, which reviewers found visibly soft. Most players will stay at 1440p 540Hz.

Is the glossy screen a problem?

In a room with controlled lighting it is an advantage: deeper blacks and a clearer image. With a window or lamp behind you, reflections are obvious. Consider the matte LG 27GX790B-B for bright rooms.

Is it different from the PG27AQWP-G?

The PG27AQWP-G 20th Edition appears to be a cosmetic variant with the same dual-mode spec. Check the model name on the listing; our review and buy link cover the PG27AQWP-W.

Final recommendation

For competitive players who want OLED clarity and a top-tier picture, the PG27AQWP-W is our pick, provided your room suits a glossy screen and your PC can feed it. If glare is a concern, the matte LG 27GX790B-B is the closest alternative; if you want strobing without OLED trade-offs, compare it with the ASUS XG27AQNGV.
