Eizo ColorEdge CG277 review

Price when reviewed

Eizo’s top-end ColorEdge displays have been a regular fixture on the A-List for years. They may be expensive, but their reputation for top-notch image quality, adjustability and features is well deserved. Eizo has updated its flagship model, the CG277: it has an improved IPS panel, new LED backlighting and a healthy sprinkling of upgrades. See also: The 9 best monitors from £200 to £2,000

Eizo ColorEdge CG277 review: features

The centrepiece of the ColorEdge CG277 is a 27in, 2,560 x 1,440 IPS panel. This might sound like old hat next to the new breed of 4K monitors we’re seeing, but what the Eizo lacks in pixels it more than makes up for in quality. The previous model’s CCFL backlight has been replaced by GB-R LED backlighting – a change that reduces power consumption and increases the colour gamut, which Eizo claims covers 99% of the Adobe RGB colour space. To ensure that every possible hue is visible onscreen, the CG277 supports full 10-bit colour inputs with a 16-bit 3D look-up table, or LUT, to maximise colour accuracy.

The CG277’s killer feature, however, is its integrated colorimeter. Whereas other monitors will drift further and further away from their factory calibration as time passes, the CG277 can automatically adjust its own colour response to compensate. The sensor is hidden away in the display’s lower bezel and, once activated, levers outwards and checks that the onscreen colours are exactly as intended. The Eizo can be set to calibrate automatically on a weekly or monthly basis, or after a set number of hours of usage, and you can set specific times so it’s ready for action before you start work. For anyone who’s battled with colour calibration in the past, it’s an absolute boon.

Needless to say, the result is a monitor that looks fantastic every time you switch it on. It also has a wide range of pre-calibrated colour presets – sRGB, Adobe RGB, Rec 709, EBU, SMPTE-C and DCI – which you can switch between by clicking the Mode button. Choose the colour space best suited to your application and the Eizo serves up supremely accurate image quality from the start.

Eizo ColorEdge CG277 review: image quality

We expected excellence from the CG277 and, by and large, that’s what it delivered. The sRGB mode covered 97.8% of the sRGB colour gamut in our tests, and achieved a colour temperature of 6,500K and a contrast ratio of 825:1. Colour accuracy was on a par with the best models we’ve seen in PC Pro Labs, too: it racked up an average Delta E of 0.7 and a maximum deviation of 1.97 – near-perfect, in other words.

With the CG277’s Adobe RGB mode enabled, the results were equally impressive. We recorded superb gamma, colour temperature and contrast ratio readings, while the average Delta E of 0.97 and maximum of 2.23 were excellent. The only disappointment was that our X-Rite colorimeter measured the Eizo as covering only 96% of the Adobe RGB colour space, a touch short of Eizo’s claims.

The Eizo’s backlight is right on the money, though. We measured no more than a 5.4% deviation across the whole panel, with an average variance of only 1.5%. To the naked eye, the panel looks evenly lit from corner to corner, and there isn’t the slightest hint of backlight leakage.
