Eizo ColorEdge CS2730
If you’re looking for a monitor with top-class image quality for professional-grade photo editing, look no further, says Edward Chester

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.
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.
