ASUS ROG PG27AQWP-W 27 Inch 1440p 540Hz Tandem OLED Gaming Monitor

The ASUS ROG PG27AQWP-W is a 26.5-inch QHD gaming monitor built around ASUS's Tandem OLED panel technology. It targets competitive and enthusiast PC gamers who want extremely fast refresh rates without giving up color quality or contrast. The two defining numbers here are 540Hz and 0.02ms, a combination that puts it well beyond what most gaming displays offer at this resolution.

The Tandem OLED panel is the core story. Compared to previous-generation WOLED panels, ASUS says it delivers 15% higher peak brightness, a 25% larger color volume, and a 60% longer OLED lifespan. That last point matters because burn-in has historically been a concern with OLED screens. The monitor also includes OLED Care Pro with a Neo Proximity Sensor, which detects when you leave your seat and switches to a black screen automatically. You can manage these settings through the DisplayWidget Center software using just your mouse, which keeps the setup process straightforward.

Color performance is strong on paper. The panel covers 99.5% of the DCI-P3 gamut, supports true 10-bit color, and meets VESA DisplayHDR 500 True Black compliance with a Delta E below 2, meaning colors should appear accurate out of the box. A color pre-calibration report is included in the box to confirm this. The TrueBlack Glossy surface removes the anti-glare haze layer found on many monitors, which sharpens image clarity, though it also means the screen will pick up reflections in brightly lit environments. The monitor operates in two modes: QHD at 540Hz or HD at 720Hz, so there is no 4K option for users who prefer higher resolution over higher frame rate.

Connectivity is a genuine strength. The included DisplayPort 2.1 cable supports the full 80Gbps UHBR20 bandwidth needed to run the monitor at its peak settings, and HDMI 2.1 is also present for console or secondary PC use. The box is unusually complete, with both cables, a USB 3.2 cable, a microfiber cloth, a ROG pouch, a VESA mount kit, and the calibration report all included. The listing does not specify built-in speakers, a USB hub, or an adjustable stand's range of motion, so buyers who need those features should verify separately.

Verdict: This monitor is a strong choice for competitive PC gamers who prioritize frame rate and color accuracy at 1440p and are willing to pay a premium for Tandem OLED technology. Buyers who game in bright rooms should weigh the glossy panel carefully, and anyone seeking 4K resolution will need to look elsewhere.

A great fit if you:

• Play fast-paced competitive games and want the smoothest possible motion at 1440p resolution
• Care about accurate, vivid color and HDR performance alongside high frame rates
• Want built-in burn-in protection that works automatically without manual intervention
• Already own or plan to buy a GPU and cables that support DisplayPort 2.1 bandwidth

Consider something else if you:

• Game in a room with strong overhead or window lighting, since the glossy panel will reflect it noticeably
• Need a 4K display or prefer resolution over frame rate for single-player or creative work

What cables are included in the box?
The package includes a DisplayPort 2.1 (DP80) cable, an HDMI Ultra High-Speed Cable, and a USB 3.2 cable, so you should be ready to connect right away without buying additional cables.

How does the monitor protect against OLED burn-in?
ASUS includes OLED Care Pro with a Neo Proximity Sensor. The sensor detects when you step away from the monitor and switches the screen to black, reducing the risk of static image burn-in over time. Settings can be adjusted through the DisplayWidget Center software.

What are the two display modes and what do they offer?
The monitor supports QHD resolution at 540Hz for the highest frame rate experience, or HD (720Hz) mode for an even faster refresh rate at lower resolution. There is no 4K mode available.

Does the monitor come pre-calibrated?
A color pre-calibration report is included in the box, indicating the panel has been factory-calibrated. The monitor also meets Delta E below 2, which reflects a high standard of color accuracy.
