ASUS ROG Swift OLED PG27AQWP-G EDITION 20 — QHD OLED at 540Hz
QHD Tandem WOLED540Hz · 720Hz HD0.02ms GtGDisplayHDR 500 True Black
The ASUS ROG Swift OLED PG27AQWP-G EDITION 20 is a 27-inch class (26.5") QHD gaming monitor with a Tandem WOLED panel running at 540Hz — or 720Hz in HD dual mode — with 0.02ms GtG response, built for top-level competitive play.
At 540Hz on an OLED panel, motion clarity reaches a level LCDs cannot match: each frame appears almost instantly and is gone before the next. The tandem WOLED structure reaches 1500 nits HDR peak with VESA DisplayHDR 500 True Black certification, and colour covers 99.5% DCI-P3 in 10-bit. FreeSync Premium Pro and G-SYNC Compatible keep frame delivery smooth, and DisplayPort 2.1 provides the bandwidth for QHD at 540Hz.
Before you order: To reach 540Hz you need a top-tier graphics card and esports titles running at matching frame rates; use DisplayPort 2.1 from a supported card. The glossy surface reflects bright light sources, and there are no built-in speakers or USB-C input.

Singular Expert Insight · Buyer's Guide
The PG27AQWP-G EDITION 20 is built for one purpose — the fastest possible motion clarity — and tandem OLED at 540Hz delivers it. It only makes sense paired with a top-tier GPU and esports games; for mixed AAA play, a 4K 240Hz OLED is the better buy. Check our
graphics cards to match it.
✓ Buy it if you play competitive esports and want the fastest OLED refresh available at QHD.
✕ Skip it if you mostly play AAA titles, need USB-C, or your graphics card cannot exceed 240 fps.
