Specs compared

Which should you buy?

• ▸ASUS ROG Swift OLED PG27AQDP runs 480 Hz vs 360 Hz — more unique frames and a lower input-to-photon floor if your FPS keeps up.
• ▸ASUS ROG Swift OLED PG27AQDP is OLED (perfect blacks + near-instant pixel response, but watch static-HUD burn-in); Zowie XL2566K is TN (the fastest, cheapest pixels — at the cost of colour and viewing angles).
• ▸ASUS ROG Swift OLED PG27AQDP has the faster 0.03 ms GtG response — cleaner motion and less smearing on fast flicks.
• ▸ASUS ROG Swift OLED PG27AQDP scores higher on our measured panel composite (100 vs 96/100) — refresh, real GtG response and panel tech weighted into one number, so two spec-sheet-similar panels pull apart. It grades the panel, not your aim.
• ▸Resolution differs: Zowie XL2566K is 1920x1080 and ASUS ROG Swift OLED PG27AQDP is 2560x1440. Lower resolution lets the same GPU push a higher FPS ceiling to feed the refresh rate (the classic esports pick); higher resolution renders enemies sharper at range. Pick by whether your rig can already max the frames.
