Ed­ward Ch­ester checks out a top-class mon­i­tor for pro­fes­sional-grade photo-edit­ing

Whether you’re a high-fly­ing pro­fes­sional or just a hob­by­ist, a good-qual­ity mon­i­tor is an essen­tial ad­di­tion to any pho­tog­ra­pher’s or videog­ra­pher’s arse­nal.

Broadly speak­ing, high- end mon­i­tors can be split into two types: those that stick to the sRGB colour space as seen for all stan­dard com­puter uses and those that deal in wider gamut colour spa­ces such as AdobeRGB and DCI- P3. If you only work dig­i­tally, you’ll gen­er­ally need a mon­i­tor that con­forms to the sRGB colour space. How­ever, if you print files to high- end prin­ters, edit video for cinema pro­jec­tion or look ahead to new high dy­namic range stan­dards such as Rec. 2020, then a higher gamut mon­i­tor is what you need, which is where the Eizo ColorEdge CS2730 comes in.

This 27-inch dis­play de­liv­ers 99% of the AdobeRGB stan­dard, mak­ing it suit­able for pro­fes­sional photography in­tended for print­ing. How­ever, it’s no style icon. It’s a bulky, heavy, thick-bezelled hulk of a thing, with a matt grey plas­tic fin­ish – the light­ness of which man­ages to make the dis­play look even more busi­nesslike than the typ­i­cal matt black of mon­i­tors.


What it lacks in flair, the CS2730 makes up for in fea­tures, though. The stand of­fers a full range of er­gonomic ad­just­ments. There’s 150mm of height ad­just, the base ro­tates 360° and the dis­play can pivot 90° into a por­trait ori­en­ta­tion. Tilt ad­just­ment is also on of­fer, though in an un­usual man­ner. The stand has a hinge half way up its length, rather than to the top. This al­lows it to of­fer a slightly more gen­er­ous range of mo­tion, start­ing at -5° and go­ing all the way to 35°.

The stand can also be re­moved to re­veal 100x100mm VESA mount­ing points, al­low­ing an al­ter­na­tive stand to be used. An anti- glare hood is avail­able separately.

On the back of the dis­play there’s an in­te­grated carry han­dle. Un­like most han­dles that are on the top of the stand – if there’s one at all – this one doesn’t cause the dis­play to tip for­ward when you pick it up. This is just one of the many lit­tle fea­tures show­ing that Eizo has re­ally thought about the de­sign of this mon­i­tor.

For con­nec­tiv­ity you get an am­ple se­lec­tion, with one each of Dis­playPort, DVI- D and HDMI, plus a USB hub with three easy-toac­cess ports on the left. An ex­tra Dis­playPort would’ve been nice for those who run two PCs.

As for set­ting up the dis­play, Eizo has pro­vided an ex­cel­lent on-screen dis­play and con­trol sys­tem. The lat­ter con­sists of six touch- op­er­ated but­tons that sit on the bot­tom right of the frame, near the touch- op­er­ated power but­ton. Th­ese are all back­lit so are easy to find, even in dimly lit rooms. There’s also an au­di­ble beep each time a but­ton is pressed, but this can be turned off.

The menus are in­tu­itively laid out and of­fer a se­lec­tion of op­tions, in­clud­ing sRGB and AdobeRGB modes, colour balance, bright­ness, colour tem­per­a­ture and gamma op­tions.

The dis­play

As for the dis­play, its 27-inch size is ideal for gen­eral-pur­pose edit­ing work. Larger dis­plays are good, but are most use­ful for multi-task­ing.

The same goes for the choice of a 2,560x1,440 res­o­lu­tion; with this you don’t have to worry about Win­dows some­times mess­ing up its res­o­lu­tion scal­ing, and you still have an am­ple desk­top space.

Eizo has gone for an IPS-type LCD panel, which is the de facto choice for a pro­fes­sion­alqual­ity dis­play. It can’t match the con­trast of VA-type pan­els or the fast re­sponse time of a TN panel, but it of­fers a very sta­ble im­age, the best colour re­pro­duc­tion and view­ing an­gles. It’s a true 10-bit panel and uses a 16-bit look-up ta­ble (LUT), so of­fers smooth colour gra­da­tion and ac­cu­racy.

Sit­ting be­hind the LCD is a wide- gamut LED back­light, and Eizo has gone to great lengths to of­fer colour and lu­mi­nance uni­for­mity that sur­passes typ­i­cal dis­plays. We mea­sured a vari­ance in bright­ness of only 1% across the whole panel, while colour changed by an av­er­age of just 1.4%. Typ­i­cal con­sumer dis­plays will see closer to 10% and 5%, re­spec­tively.

Work­ing with sRBG and AdobeRGB

Test­ing the per­for­mance of the de­fault con­fig­u­ra­tions for sRGB space and AdobeRBG on the menu, the CS2730 per­forms per­fectly. In sRGB mode, the dis­play reg­is­tered a near-per­fect white point of 6,513K while its sRGB colour space cov­er­age is 94.8%. This might sound lower than ideal, but in prac­tice, it’s close enough to the 100% cov­er­age you’d ex­pect. Like­wise, a gamma score of 2.28 is close to the ideal of 2.2 and an av­er­age Delta E of just 0.12 (max 1.66) is ex­cep­tional.

The only area in which this dis­play looks a bit pedes­trian is con­trast. With a fig­ure of 864:1, it’s not the most dy­namic of dis­plays, but even the best IPS pan­els can gen­er­ally only push to 1200:1 so it’s within touch­ing dis­tance.

The dis­play largely ex­celled in AdobeRGB, too. A cov­er­age of 92% is tech­ni­cally a lit­tle lower than we’d ex­pect, but in prac­tice un­likely to be a con­cern, and this is be­fore be­ing man­u­ally cal­i­brated. Once cal­i­brated all th­ese fig­ures tight­ened up fur­ther, show­ing a near flaw­less colour pre­pro­duc­tion per­for­mance.

The dis­play also of­fers the abil­ity to man­u­ally dial in all set­tings, but with such good im­age qual­ity in its de­fault modes, there’s lit­tle need for this.
