Eizo ColorEdge CS2730 monitor review

Yes it is possible to buy a 27-inch monitor from Eizo, ColorEdge what is more (synonym of quality at Eizo) around £900! But in what proportions is this new CS2730 superior to the 27-inch of the market? That's what I suggest you see in this test.

EIZO CS2730 monitor


To quickly present this new Eizo monitor, the second in the ColorEdge series which replaces the excellent Eizo CS270 (which still does not have a colorimeter), we can say that it is a 27-inch monitor (2560 x 1440 - pitch 0,23 - 108 ppi) with satin slab of new generation which is addressed to photographers and other graphic designers but also to videographers, with technology IPS (LED white diodes), table LUT on 10/16 bits and with broad gamut thus covering a gamut very close to Adobe RGB 98 / DCI-P3. It therefore falls into the category of monitors called "Graphic Arts". It is still sold under £1,000 (Spring 2018).




Présentation of the Eizo Coloredge CS2730 monitor

To start, here are some illustrations of this new screen with flawless ergonomics, really improved compared to the CS270 (handle, thin edges, screen rotation, electrostatic buttons)... as on the beautiful Eizo CG2420.

What you'll find inside the box...

The screen is sold with :

  • Its power cord... long enough!
  • A DVI cable
  • A USB 3.0 cable for hardware calibration and to power the USB HUB.
  • Colornavigator on a CD


Important note! The Eizo CS have no colorimeter...

This CS2730, like the CS270 it replaces, does not have a built-in colorimeter (unlike the CG2730) so you will need to use or purchase one.

My buying tip: i1Display Pro, Spyder5Elite or EX3!

Bulkiness and perceived quality

The 27-inch monitor is 25,12in wide and has a 23,60in wide slab. The monitor is therefore significantly less bulky than the CS270 lamp it replaces. That's good news for those who want to build a multi-screens configuration!

The screen and its panel - New

Eizo CS2420 monitor1 - Definition/resolution - It is therefore a new IPS slab, therefore different from the CS270, satin, which is common in this 2,560 x 1,440 pixel "Graphic Arts" monitor niche. Its resolution is therefore 108 ppi. Classic and not "Retina", this monitor and its extremely discreet "granularity" is very similar to the CS270. The backlight is of the white LED type as on the old CS270.

2 - The panel and its anti-reflections treatment - New - The anti-reflection treatment of the old CS270 had marked an important step because finally, it was subtle and almost invisible on the pixels. I never complained about mine (on a CS270) and this new plate seems to have a very similar treatment, that doesn’t reach the smooth finish of the CG2420 though.

3 - Program for hardware calibration - This screen is sold with its calibration program: the famous ColorNavigator – It is supposed to guarantee you an ideal calibration, easy to perform moreover for those of you who don't really master the meaning of all target values – without a built-in sensor though. So you'll have to own a compatible sensor to be able to use it. All good then.

With that in mind, screens improved so dramatically that even with a "simple" calibration using the i1Display Pro + iProfiler, you get results that will appear perfect to your eyes nowadays. Only the figures can still be improved with this kind of hardware calibration but it's beyond our perception threshold.

Note! I can understand that brands communicate on their hardware calibration program though, because you'll be absolutely "certain" to optimize all the settings of your calibration, especially the display of grey gradients, but what I also see is that these programs that definitely added a value a few years ago are now a lot less crucial (and I'm weighing my words carefully), at least on top-range screens like this one. You want absolute perfection, go for it. Even if your eyes can't see a difference, you'll be at peace with your conscience!

Thickness of the edges of the screen - New


Now they're 18 mm thick on each side of the screen and thus lost 1 cm on the right, 1 on the left and almost 3 at the bottom. It's not a thinness record but it's getting early 2018 standards favoring multi-screens configurations. (Read: my recommendations to choose your photo screen )


From the classic early 2018: DVI-D, HDMI, DisplayPort and a USB 3.0 socket (which can be used for hardware calibration and one to power the USB 3.0 HUB of 3 USB 3.0 plugs on the left side of the monitor - see above ):


Connectivity Eizo CS2730

Improved (see photos above) ergonomic design!

Ergonomic design has been noticeably improved, especially for transportation since a new handle on top and at the back of the screen has been added, also very convenient to adjust its height. Still no wire grommet in the foot though. The range of motion of the screen in height (on 15.5 cm / 6.1in), tilting and rotation will enable all users to find their ideal settings. Perfect really!


Ergonomic design of the EIZO CG2420


Other new feature, the menu buttons on the screen are now electrostatic, a lot more elegant than on the CS240 and with a nice ping (that can be muted) when you press them. This new screen is definitely really refined...


Electrostatic buttons of the Eizo CS2420


The buttons of the screen menu are now electrostatic but the OSD has remained the same.

Note! In the screen's OSD it is possible through the menu Preferences Indicator to change the brightness of the LEDs or even to turn them off for those who work in the dark. Well thought!




What is the calibration of the Eizo CS2730 worth with the i1Display Pro?

I first calibrated this screen – like all the screens I review – with the best current sensor (except the superlative and very expensive Discus) which is in addition great value for money: thei1Display Pro + program iProfiler (version 1.6.6) in order to be able to compare this screen to other screens on the market. The values are very similar to the CS240’s it replaces.

I chose the following screen settings:

  • Color space: Custom
  • Gamma: Adobe RGB 98 (2.2)
  • Default 50% contrast,
  • Color temperature: 6,500K (Adobe RGB 98).

And as target values in the program iProfiler 1.7.2...

  • Screen technology: Choose white LEDs,
  • D65 or possibly a bit less if you want a slightly warmer screen. (Please note that at D55, the screen is really warm but not yellow like low-range screens),
  • Luminance: 100 Cd/m2 (so 34% on the screen) or more depending on your main use (print or web) and above all the brightness of your room,
  • Contrast : Native or 287:1 for those who print a lot,
  • Gamma 2.2 with a standard curve, (the L* is only available with ColorNavigator and there's a lot to say about this L* gamma anyway)
  • ICC norm: V2 (to avoid incompatibility problems with certain images viewing programs (too dark images) and of course V4 if you know what you're doing.

And the result is?

Objective data: what does the final report say after calibration?

Before discussing the Delta Es, it’s interesting to point out the color temperature values and contrast values reached.


Final report after calibration Eizo CS2730 monitor with iProfiler


My opinion! Is it a coincidence that the color temperature is of course at 6,500K and not approaching like on lower-range screens? The contrast is in the average of the screens using these tiles. This tile is therefore different from the CG2730 which replaces the CX271 and whose contrast is doubled. This may be the weak point of this monitor...

The figures of Delta E according to the 2000 standard are obviously excellent and finally very close to the old CS270 after a calibration with the probe i1Display Pro thus without going through a hardware calibration and Colornavigator.


Final Delta E report of the Eizo CS2730


My opinion! My test copy offers, as all the Eizo monitor of the CS series, perfect colors for a human being with an excellent view: 0.45 of average and the worst patch at 1.39 according to the 2000 standard. So this new CS2730 is what you'd expect from an Eizo ColorEdge display!

Let's now see the tests of brightness and color temperature harmonization:

Report after calibration of Eizo CS2730 – Homogeneity brightness


Once again, superlative values! You want to know what a 27-inch homogeneous panel is? Well borrow or buy this CS2730!


Measurement of brightness homogeneity on Eizo CS2730

In color temperature, it's just as superlative on my test copy. So few 27-inch do that well. I've rarely seen that in this size. Bravo Eizo!

What about subjective data: what does my eye see?

First of all, it is necessary to note the very weak presence of leaks of lights in the dark. That changes! So many screens sometimes have big leaks of light. I'm not saying there aren't any, but frankly, I don't think it's so embarrassing that it's difficult for me to show it in pictures.
Then, the CS270/CX271/CG247, which shared the same tile, were references in terms of color display quality, grayscale, gradation, subtleties in saturated colors, shade display, uniformity, anything you want! The tile of this new CS2730, although different from the magnificent CG2730 which has a double contrast (1500:1 instead of 680:1), is equal with him in terms of colour and it is difficult to tell them apart visually. If you own an Eizo CS270, you could still be tempted by the many ergonomic and connectivity improvements and be sure to get what I would call a perfect display. I like calibrating ColorEdge Eizo series!




Conclusion and my rating!

Eizo CS2730 monitor

The Eizo CS270 and CX271 shared the same tile but this Eizo CS2730 has a different tile from the CS270 fire it replaces but also different from the superb CG2730. While the CG2730 significantly improves the CX271's display with double contrast, the CS2730 looks a lot like the CS270. On this criterion alone, it does not seem necessary to do the update. Now remains a greatly improved ergonomics: the new handle so practical, its state-of-the-art connectivity (USB 3.0), its menu keys now electrostatic so pleasant to use, its edges largely thin (- 10 mm on each side) for multi-screen use. So it's up to you to see if that justifies the replacement. If this is your first purchase, you will be won over and you will never regret having invested 20 unfortunate cents more per day than most of its direct competitors over five years that its warranty lasts!

Should I replace my Eizo CS270? So should we replace his Eizo CS270 with this Eizo CS2730? Probably not unless the ergonomic improvements and connectivity make you eye.

  • Figures after"perfect" calibration in practice,
  • New"satin" matt IPS tile with superb rendering,
  • Wide gamut for photographers (Adobe RGB 98),
  • Thin edges, on all sides: 18mm instead of 28... finally!
  • Updated connectivity (USB 3.0),
  • Improved ergonomics (very practical handle, electrostatic buttons, rotation)!
  • 5-years warranty,
  • Real favorite product!
  • No visor included, because for the rest I'm still looking...
  • If, looking carefully, perhaps the slight lack of contrast with the CG2730.
9.75 / 10

My opinion:
There's no need to say: the Eizo monitors of the CS series are something else! What a treat to test such monitors. Even in 27-inch Eizo can make homogeneous slabs. Really, put the £200 more compared to the competition, you will not regret them. I assure you.
Then why"only" 9.75/10? Just to leave 10/10 to the CG2730 which offers a double contrast. Because for the rest this CS2730 is only perfection at only £940! Yes I assume, at only £940!

This website is almost entirely free and yet almost free of ads. Why? Because they look so bad! It is lucrative though, and enables many websites to keep on living. So I asked myself: what can I do? To keep on developing this website, I'm going to need a regular income just like everyone else. How can I keep on giving access to free information like I've been doing since April 2002?

And I finally found the answer: affiliation. Every time you click on a link from this site to one of my partners' shops, they know you've been referred by me and give me a small percentage on your purchase, be it something I recommend on my website or anything else. Remember to use my links when you shop on these sites! It doesn't cost you anything and it's a win-win deal – for me, them, and you!
