Asus PB278Q review: Great performance at a good price

The Asus PB278Q is yet another well-performing 27-inch, extreme-definition monitor that falls just short of matching its strongest competition in value.

In the world of extreme-definition monitors, the Asus PB278Q almost perfectly hits a happy medium between features and value. I reviewed the HP ZR2740w earlier in 2012, and while that monitor offered great performance at a reasonable price, aside from brightness, customization features were nowhere to be found.


Asus PB278Q

The Good

The <b>Asus PB278Q</b> offers a sharp extreme-definition screen, rich color, accurate presets, and useful ergonomic options at a good price.

The Bad

The monitor lacks USB inputs and its swivel mechanism is poorly implemented.

The Bottom Line

Well-priced and powerful, the Asus PB278Q is the best entry point for those seeking an extreme-definition monitor at a not-so-extreme price.

The PB278Q is like getting the ZR2740w with better performance, and with a great assortment of customization features at about the same price. The Asus can't quite match the performance of the $100 more expensive Dell U2713HM and lacks the Dell's USB ports and plentiful assortment of presets, but for $100 less it's a great lower-priced alternative for those looking to save a few bucks on an extreme-definition monitor.

Design and features
The 27-inch Asus PB278Q is one of the first non-Samsung monitors to house a plane-to-line switching (PLS) panel. Previous to this, the Samsung SyncMasters S27A850D and S27B970 hold the distinction as the only other two monitors to feature the company's still relatively new panel tech. Like most monitors produced today, the PA248Q houses a white LED backlight resulting in a fairly thin, 2.6-inch deep chassis. Also, at 19.4 pounds, it's surprisingly light for a 27-inch monitor.

The bezel measures 0.8 inch on the left and right sides with the full width of the panel checking in at just under 25.25 inches. The 11-inch-wide footstand is the monitor's most eye-catching visual trait, measuring 11 inches by 8.6 inches. When knocked from the sides, the monitor does wobble more than I'd like. This is not too surprising when the swivel mechanism, located on the bottom on the foot stand, is taken into account, as it keeps the stand from sitting completely flat. Unfortunately, due to the awkward implementation, the entire chassis swivels when rotated, not just the screen.

Speaking of which, the monitor can swivel left and right, tilt back 20 degrees, and pivot 90 degrees, and its screen height can be adjusted by about 4.5 inches.

Connections include DVI, DisplayPort, VGA, HDMI, a headphone jack, and an audio-in port. The connections face downward and would be difficult to access save for the always-useful pivot feature.

The onscreen display (OSD) array consists of six buttons located in the lower right of the bezel on the underside of the panel and includes a preset shortcut, a Menu button, and a Source button. The buttons are separated from each other by about half a button's length of space and emit a satisfying snap when pressed.

Navigating the OSD feels a bit clunky, as the menu button and and preset shortcut buttons act as enter and exit button, respectively; I wish Asus could have found a less confusing way to implement its OSD controls. The OSD features Standard, sRGB, Scenery Mode, and Theater Mode presets, plus one additional customizable User Mode. Also included are brightness, contrast, saturation, hue, gamma, and advanced color settings, among which are six-color hue and saturation adjustment controls and direct RGB color control using gain and offset. Rounding out the more useful options are sharpness, aspect ratio control, picture-in-picture (PIP) settings, and system setup options such as OSD window placement and duration onscreen.

By far the most unusual feature in the PA248Q's already considerable assembly of OSD options is QuickFit. QuickFit places an overlay on the screen of your choice of either grid patterns (of various units of measure) or paper and photo sizes. With the grid patterns you can more precisely and consistently organize content on a page when, say, designing graphics for the Web.

The paper and photo sizes would show exactly what papers and photos would look like once printed. This one seems less useful, as any self-respecting graphic artist would probably already be using Photoshop or some other program to do this. Still, it's a unique option that some will get more use out of than others.

I tested the Asus PB278Q through its DisplayPort input, connected to a Windows 7 PC, using the included DVI cable. The display posted a composite score of 96 on CNET Labs' DisplayMate-based performance tests.

DisplayMate: The PB278Q displayed light gray up to level 254; 255 is considered white, and every level between it and 1 is a variation of gray, so 254 is as high as you can get. The PB278Q's performance here indicates that the display would retain its contrast ratio and likely not be prone to washing out light colors. As for dark gray, the U2713HM just barely displayed down to level 6 while still maintaining a deep black, which points to the display not being capable of retaining dark detail during dark scenes in movies.

The PB278Q excelled in most of our color tests, but didn't display color as accurately or as smoothly as the U2713HM, displaying more obvious jumps in color scale progression.

In our Dark Screen test, I stare at a screen devoid of color in an attempt to identify spots where light from the backlight seeps through (known as “clouding”). While some noticeable light bled through the upper right corner, the PB278Q did a pretty good job at keeping unwanted light at bay and overall, the PB278Q displayed less backlight bleedthrough than the Dell U2713HM.

Text: Black text on white looked clear, without any obvious color tint problems. Also, fonts were clearly visible down to a 6.8-point size.

Movies: I tested the Asus PB278Q using the Blu-ray version of "Avatar." The Theater preset provided a decent picture. The colors were vibrant, but the color temperature was a bit too cool and dark detail was practically nonexistent. The Standard mode fared a bit better for dark detail, but wasn't as vibrant.

Games: When evaluating the look of games on a monitor, the two most important features to consider are vibrancy and color. If the monitor can display games with a bright and vibrant cleanness, this goes a long way toward benefiting its looks. If colors can also pop with fullness and depth, games can usually look great. Streaking is a different concern that, honestly, isn't very pervasive with most modern monitors, but if you're concerned about it, be sure to check out the last paragraph in this section.

Different still is input lag, which is, put simply, is the time it takes from when you input an action through your keyboard, mouse, or game pad to when you see that action represented onscreen. Every monitor has a degree of input lag, but only a very small percentage of people would even notice it. Given that, it's not something I find valuable enough to test for. PSA, over.

Games looked best when using the Scenery mode. The saturated colors made games like Crysis 2 and Syndicate pop from the screen with vibrancy.

Josh Miller/CNET
To test refresh rate, I used DisplayMate's motion graphics tests and stared at a number of colored blocks as they moved around the screen at various speeds. The pb278Q displayed large afterimages of the blocks as they shifted across the screen, but I didn't notice this level of ghosting when actually playing games.

Photos: When looking at faces and light-colored hair in the Standard preset, the PB278Q presented faces with accurate color, especially when using the sRGB preset.

Josh Miller/CNET
Recommended settings: Each preset is tailored quite well for its task. For general use, however, I preferred the SRGB preset where colors remain accurate and suitably saturated.

Viewing angle: The optimal viewing angle for a monitor is usually directly in front, about a quarter of the screen's distance down from the top. At this angle, you're viewing colors as the manufacturer intended. Most monitors aren't designed to be viewed at any other angle. Depending on its panel type, picture quality at nonoptimal angles varies. Most monitors use TN panels, which get overly bright or overly dark in parts of the screen when not viewed from optimal angles.

Josh Miller/CNET
Antiglare (AG) screen coating plays a part as well. Some viewers prefer that the coating not be applied at all, while others favor only a limited amount. Still, others are completely indifferent; however, AG coating doesn't adversely affect quality, and its merits, or lack thereof, are strictly a matter of preference.

The PB278Q uses an PLS panel, which provides it with a wider-than-TN viewing range while also matching most high-end IPS displays.

The AG coating works fairly well here, keeping out most reflections while retaining a high-contrast, vibrant look; however, on a black screen viewed from an off angle, some blurry impressions of the environment are visible. That's likely not an issue unless you plan to constantly bathe it in natural light.

Josh Miller/CNET
Power consumption: Armed with an LED backlight, the Asus PB278Q achieved fair power consumption, with a Default/On power draw of 41.5 watts, compared with the Dell UltraSharp U2713HM's 38.4 watts in the same test.

In our Sleep/Standby test, the PB278Q costs 0.43 watt and the U2711 pulled a lower 0.35 watt. Based on our formula, the PB278Q would incur less than half the cost of the U2713HM, with a per-year pull of $12.68, compared with the U2713HM's $11.70 per year.

The PB278Q is an excellent monitor with useful ergonomic options and features. While it performs admirably, its picture quality doesn't quite measure up to the Dell U2713HM's; however, with a $100 cheaper price tag, it may not have to.
