ASUS PB278Q 27in LED Monitor 300cd/m 2560x1440 5ms HDMI/DVI/DP/VGA Audio

- Replaced by the ASUS PB287Q 28in 3840 x 2160 TN 1ms Monitor, 2x HDMI, DP

A tremendous WQHD (wide quad HD) monitor for general PC work, especially photo and video editing. Its incredible high resolution, fine detail and low power requirements will be a boon to its user for many years to come.

Precision to the Finest Detail: Professional 27” 16:9 Monitor

Can you envision a bigger monitor with 2560 x 1440 WQHD, packing four times the pixel density of 720p?!! The new premium 16:9 wide-format PB278Q LED display affords 178° wide viewing angles for better productivity, opening extra multitasking space to fit more windows and projects on-screen. ASUS exclusive Splendid Video Intelligence Technology, QuickFit Virtual Scale, and 100% sRGB fidelity ensures reality-defining colour and image accuracy, giving you true “what you imagine is what you create” power. DisplayPort 1.2, HDMI 1.4, and dual-link DVI all natively support WQHD , which is accentuated by room-dominating audio via twin 3W speakers. To help you stay naturally focused, its ergonomic design includes tilt, swivel, pivot, and height adjustment, plus streamlined cabling that keeps clutter off your desktop.

See Better and Wider

The PB278Q features a 16:9 aspect ratio and a LED-backlit 27” WQHD display that provides 109 pixels per inch (PPI), resulting in high quality 2560 x 1440 visuals – equalling four times the resolution of standard 1280 x 720 monitors. It allows users to view greater image detail and do more with an on-screen footprint larger than that of standard displays.

The screen’s 109PPI density means there are 109 RGB matrices within one inch. Generally, the more pixels a display has, the more lighting (or power) those pixels require to achieve the best visuals. However, with advanced LED back-lighting on the PB278Q, power and energy savings are no longer compromised, while better visuals are assured.

Made for Work and Play

The ASUS PB278Q features a PLS panel which provides an ultra-wide 178° viewing angle on both horizontal and vertical planes, thereby minimising on-screen colour shift even when viewed from extreme angles. With its WQHD display, you can enjoy 77% more desktop space than a full HD screen to spread out your windows and palettes. It is also approximately 25% sharper than a generic 27” full HD display, delivering ultra-smooth visuals thanks to 5 ms (grey to grey) response time. This ensures that you get lag-free experiences in movies and gaming, with the latter looking more vivid, ensuring that all in-game details shown in true colour. The ASUS PB278Q is undoubtedly your best choice for work and play.

Smart Contrast Ratio for lifelike visuals

With 80,000,000:1 ASUS Smart Contrast Ratio (ASCR) and 300cd/m² brightness, the PB278Q enhances display contrast and sharpness by adjusting backlight luminance to achieve the deepest black tones and brightest whites, resulting in extra-clear visuals that truly come to life.

QuickFit Virtual Scale for true what you see is what you get

ASUS includes its exclusive QuickFit Virtual Scale feature with the PB278Q, allowing you to preview photos and documents on-screen in their actual size prior to printing. This can be activated via a monitor hotkey, and serves as a highly useful guide to accurately view and edit photos in their native size. Supported formats include documents (A4, letter), photos (8”x10”, 5”x7”, 4”x6”, 3”x5”, 2”x2”) and grid alignment.

Splendid™ Video Intelligence Technology

Driven by a precision colour engine that automatically analyses and determines the nature of your current task, Splendid Video Intelligence Technology adjusts display parameters accordingly to ensure colour accuracy and image fidelity. Six preset modes (scenery, theatre, sRGB, standard, and two user-customisable modes) can be quickly selected via a designated hotkey.

Designed with You in Mind

The PB278Q offers a highly ergonomic and smart design that comes with tilt, pivot, swivel, and height adjustments to ensure an always-comfortable viewing and usage experience. Its smart cable management further promotes clutter-free spaces for work and enjoyment.

Customer Reviews

Does what it says on the tin


I've replaced a pair of Dell 24" monitors with a pair of these and am delighted with the extra screen real estate on my Win 8.1 64-bit system. Not a gamer, so I can't assess that. Don't need the built-in audio, but it's fine for quiet, late-night use.
