ASUS PB278Q 27-inch WQHD PLS LED Monitor Review

ASUS-PB278Q WQHD LED PLS 27-inch 2560x1440 Monitor Review - Intro Iso View

IPS displays have been around for quite some time now, and have long been the standard in color accuracy and overall vibrance.  However, they suffer from poor input lag and response time performance, and those who watch movies or play games on IPS displays often complain of ghosting.  PLS display technology promises color accuracy and contrast ratios which will rival IPS while reducing input lag, ghosting, and power consumption, making it a jack-of-all-trades display.  This is our first PLS panel we've gotten our hands on, so let's dive right in.

ASUS PB278Q Overview

Envision bigger with 2560 x 1440 WQHD, packing four times the pixel density of 720p! New premium 16:9 wide-format PB278Q LED displays with PLS panel afford 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 ensure reality-defining color and image accuracy, giving you true “what you imagine is what you create” power. HDMI, DisplayPort, and dual-link DVI support WQHD natively, accentuated by room-dominating audio via twin 3W speakers.

Included Accessories

Being a higher-end monitor, we'd expect some good breadth of accessories included in the box.  ASUS doesn't disappoint by providing a cable for each of the inputs, so it's ready to get hooked up to whatever you will have available, be it VGA, DVI, HDMI, and/or DisplayPort.  An included audio cable will allow you to use the speakers (rather unlikely) with DVI and VGA connections.  Other than that, since there are no drivers necessary, the only other inclusions are the power cord and warranty card.
