26.5-inch dual-mode OLED monitor
The ASUS ROG Swift PG27AQWP-W is a 26.5-inch OLED gaming monitor built around a tandem dual-layer panel. It delivers a 2560 x 1440 resolution at up to 540 Hz and can switch to 720p at 720 Hz for maximum motion clarity. The panel covers 135 percent sRGB and 99.5 percent DCI-P3 with a 1,500,000:1 contrast ratio and 0.02 ms response time.
Competitive players wanting speed and fidelity
This monitor suits esports competitors who need both high resolution and extreme refresh rates in one display. The dual-mode hotkey lets users trade resolution for speed without changing hardware. Buyers who want more screen area or a curved format should look elsewhere, as the panel is a flat 16:9 26.5-inch model. Users needing built-in speakers or Thunderbolt connectivity will not find them here.
DisplayPort 2.1a and USB 3.2 hub
The single DisplayPort 2.1a port supports UHBR20 bandwidth for uncompressed 540 Hz output at native resolution. Two HDMI 2.1 ports provide console and secondary PC connections. Three USB 3.2 Gen 1 Type-A downstream ports act as a convenient hub for peripherals, reducing cable runs to the host system. The 55 W power draw comes from an internal 100-240 VAC supply with no external brick.

Questions about this item
What GPU output do I need to run the 2560 x 1440 resolution at 540Hz?
You need a graphics card with DisplayPort 2.1a (UHBR20) to deliver the full 540Hz at QHD. HDMI 2.1 ports are also available but may limit the maximum refresh rate at this resolution.
Will my existing HDMI 2.0 cables work with the PG27AQWP-W?
HDMI 2.0 cables cannot support the 540Hz or 720Hz modes. You must use the included DisplayPort 2.1a cable or certified HDMI 2.1 cables to access the dual-mode refresh rates.
How can I confirm the monitor is actually running at 540Hz after setup?
Open the on-screen display menu and select the Information tab; it shows the current input timing. You should see 2560 x 1440 at 540Hz. Windows display settings will also list 540Hz as the active refresh rate.
