Dell UltraSharp U2711 - LCD monitor - 27"

(Part #: U2711)
5 stars

CNET Editors' Rating

5 stars 2 user reviews

The Good H-IPS panel. Great resolution. Huge array of inputs. Offset and gain control. RGBCMY hue and saturation control. 24p support. Excellent HQV scores. sRGB and AdobeRGB modes.

The Bad Input lag might be disturbing to competitive gamers. Ever so slight judder. More granularity over offset would be nice. No ATW polariser, so white IPS glow is present.

The Bottom Line With a huge resolution, excellent performance in both colour and movies, and a huge amount of inputs, the U2711 excels in almost every area it puts its mark to. Hardcore gamers may be a little wary of the input lag, and others of the cost — but if you can afford one, you'll likely be very, very pleased.

Following up on the U2410 and 2209WA , Dell's updated its 27-inch screen, leaving the 3008WFP as the last of its premium range yet to receive a makeover.

Its predecessor, the 2709W is still on sale under Dell Australia's business section for AU$999 — although we imagine this won't last too long, as it's currently limited to two units per customer, and the higher spec U2410 is only AU$200 more. The 2709W was a 1920x1200 screen like its 24-inch brethren, but with a larger pixel pitch; something that would perhaps help those who found that 24-inch screens were difficult to read. It was a VA-based screen that started Dell's current design ethos of the black bezel and proximity/touch-sensitive buttons.

The U2711 goes the other way. At a resolution of 2560x1440, it's second only to 30-inch monitors (excluding some freak occurrences), by virtue of opting for a 16:9 ratio over the usual 16:10. Think iMac 27, but without the Mac or the gloss bit. It's also dual-link DVI territory, so you'll need a graphics card that can handle the output.

As a consequence of the resolution and screen size, text and icons at default look tiny. Windows 7's DPI scaling handles this minor hurdle perfectly, allowing elements to be scaled to comfort, but Windows XP's messy implementation leaves a lot to be desired, and in some instances may leave you squinting.

What else is new? The U2711 steps up from its VA roots to be H-IPS based, meaning theoretically better viewing angles and colours, and features 12-bit internal processing for smoother greyscale gradients. There's also a few colour management surprises under the hood... so let's get cracking and see what this super resolution monster has to offer.

Stand and ergonomics

We've long loved Dell's stand, with its rack and pinion height adjustment, swivel adjustment through the neck rather than the base, and tilt adjustment and cable management through the neck. Sadly, the U2711 (unlike its smaller cousin, the U2410) doesn't pivot, meaning no portrait mode. Mind you, the height of the stand would have to be significantly increased to even attempt this, and we're not too fussed by its omission. One thing we do miss, however, is the button release to separate the panel from the stand — in this case you'll need to get funky with a torx driver in order to get it off.

The Dell stand is great, but the sheer size of the monitor means the 90° pivot function has been removed.

Dell UltraSharp U2711 inputs

The U2711 continues Dell's massive input tradition. Power, speaker bar power, 3.5mm audio jacks for 5.1 sound, DisplayPort, 2x Dual-Link DVI, VGA, HDMI, component and composite, USB upstream and two USB ports. (Credit: Craig Simms/CBS Interactive)

Buttons and on-screen display (OSD)

Things have shifted minutely since the 2709W. While the buttons remain capacitive, the power button is now mechanical, preventing accidental turn-offs. The rest of the buttons are still proximity sensitive: they stay unlit until a hand comes near them, then the bottom button lights up. Press this, and the menu appears, along with context-sensitive options described next to each button. It's a powerful and well-designed UI that's served Dell well.

The menu contains Dell's usual vastness of options including picture by picture; RGB/YPbPr colour space setting; PC or Mac Gamma modes; Graphics and Video modes, each containing their own presets; fill, aspect and 1:1 scaling; sharpness settings on digital inputs; and AdobeRGB and sRGB modes.

What caught our attention though, was the claim that the U2711 supported six-axial colour calibration (RGBCMY), as well as hue, gain, saturation and offset controls. It took us a little while to discover, but you have to put the U2711 into Video mode to turn these on, and then select the "Custom Color" preset mode. For this sort of control you usually need to shell out for a hideously expensive professional monitor — Dell is continuing its tradition of bringing these features to the grasp of the ordinary consumer.

The other profiles under the "Graphics" setting are "Standard", "Multimedia", "Game", "Warm", "Cool", "Adobe RGB", "sRGB" and "Custom Color", while under "Video" you get "Movie", "Game", "Nature", "Custom Color" and if you have an xvYCC compliant source, "xv Mode". While the PlayStation 3 supports this, we had no source material available to test.

A side note — while we were unable to discover the service menu, turning the monitor off, then holding the bottom two buttons down and turning it on again would load a display showing the backlight time and power consumption. Unfortunately, this also disables the menu, and the only way to get things back to normal is to turn the monitor on and off again.

Performance LCD tests
After calibrating to a target brightness of 140cd/m² with an X-Rite i1Display 2, Eye-One Match 3 and tweaking with HCFR, the U2711 was run through the LCD tests.

Greyscale gradients were flawless, with only test 4a in the pixel walk tests flickering.

Input lag
Measured against a Samsung SyncMaster 975p CRT, and using a Canon 40D set to a shutter speed of 1/320, an average of over 60 photographs were taken using Virtual Stopwatch Pro. Things weren't so great for the U2711, clocking in at 33ms on average, which equates to about 2 frames. Unlike the U2410, switching to game mode did not reduce this in any way.
