Asus PB278Q review
27in screen size, 2,560x1,440 resolution, DVI: yes, VGA: yes, HDMI:
We were impressed with the monitor's image quality right out of the box. Our Dispcalgui calibration software and Spyder4Express colorimeter reported the screen as displaying 98.4% of the sRGB colour gamut at its default settings, and once we’d calibrated the monitor it was within 99.1% of sRGB. Even if you don't calibrate the screen, you can be confident that you'll be getting good colour accuracy; by contrast, we feel you need to use a calibrator on Viewsonic's screen to get the most out of it.

The figures were borne out in our subjective image tests, where we could find little, if anything to complain about. In our solid colour tests colours were saturated and even across the monitor's surface and blacks were deep with no leakage from the backlight. In our image tests we saw plenty of detail in both light and dark areas, showing off the monitor's impressive contrast.
Asus's PB278Q has superb colour accuracy even at its default settings, so, while we'd still recommend using a calibrator to get the most out of a monitor this expensive, you can still be sure of getting a decent picture even without any specialist equipment. It doesn't have as much physical adjustment as the Viewsonic VP2770-LED and there's no built-in USB hub, but is a useful £50 cheaper. If you want pivot adjustment, a USB3 hub and a very high stand, then Viewsonic's screen is the one to go for, but if you can do without the fancy extras Asus's screen is the one to buy.
