Eizo CS2730 monitor


Review of the Eizo ColorEdge CS2730

Published on May 15, 2015  |  Updated on May 15, 2020


Yes it is possible to buy a 27 inch screen from Eizo, ColorEdge and more (synonymous with quality at Eizo) around $1,200 ! But in what proportions is this new CS2730 higher than the 27 inches on the market ? That's what I suggest you see in this test.

Eizo CS2730 will be replaced by the Eizo CS2731 (with USB-C) or another screen...In the meantime, you can buy the beautiful Eizo CG2730 (double contrast, integrated colorimeter and hood).

To quickly introduce this new Eizo display, the second in the ColorEdge series that replaces the excellent Eizo CS270 (which still does not have a colorimeter), we can say that it is a 27 inch display (2560 x 1440 - pitch 0,23 - 108 ppi) with a new generation satin panel which is intended for photographers and other graphic designers but also for videographers, with IPS technology (LED white diodes), 10/16 bit LUT table and wide gamut therefore covering a gamut very close to the Adobe RGB / DCI-P3. It therefore falls into the category of so-called "Graphic Arts" screens. It is still sold just above the 1200 dollar mark (End 2019).


In a few words...


Eizo ColorEdge CS2730

Soon replaced by Eizo CS2731

A 27-inch so close to perfection at just over $1,200 but it is necessary to leave 10 / 10 to the Eizo CG2730, its big brother displaying a double contrast and an integrated colorimeter + hood! - Read my conclusion

Introduction to the Eizo CS2730

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 magnificent Eizo CG2420.

What's in the box...

The monitor is sold with :

  • The power cord... long enough !
  • The DVI cable in 2017 is visibly replaced by a DisplayPort cable in 2018.
  • A USB 3.0 cable for hardware calibration and powering the USB HUB.
  • ColorNavigator in CD

Important note ! The Eizo CS series displays do not have a built-in colorimeter

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

My purchasing advice : the i1Display Pro or SpyderX Elite

i1Display Pro review


The dimensions and perceived quality

The 27-Inch monitor is 637 mm wide and has a 598 mm wide panel. The screen is therefore significantly less bulky than the old Eizo CS270 lamp it replaces. So this is good news for those who want to create a multi-screen work environment !

The monitor and its panel - New !

1 - Definition/resolution - It is therefore a new satin-finish IPS panel, normal in this niche of so-called "Graphic Arts" screens, measuring 2560 x 1440 pixels. Its resolution is therefore 108 ppi. Classic and not "Retina", this display and its extremely discreet "granularity" are very similar to the Eizo CS2420, the backlighting is of the white LED diode type as on the old CS240.

2 - The panel and its anti-reflective coatingNew - The anti-reflective coating of the old CS270 was an important step because it was finally discreet and hardly "marked" the pixels anymore. This new panel looks at least the same. It's almost "velvety"! It's not 4K yet, but we're getting closer.

3 - Hardware calibration software - This screen is sold with its calibration software: the well-known ColorNavigator - It is supposed to guarantee you an ideal and above all easy calibration, for those who do not master the meaning of all target values - but without any built-in sensor. It will therefore be necessary to have a compatible colorimeter to use it. Nothing but good, then.

That said, the screens have made so much progress that even with a "simple" calibration with the i1Display Pro + i1Profiler, we now obtain a result that will appear perfect for our eyes. Only the numbers can be improved with this type of hardware calibration but below our perception threshold.... Unless you want to calibrate it in hardware for use calibrated on another computer or in another environment because the ICC profile is directly integrated in the LUT table of the latter and not in the computer that was used to calibrate it.

Note about the hardware calibration ! However, I understand that the brands communicate on their hardware calibration software because you really are "sure" to optimize all the parameters of your calibration, especially the display of grayscales, but I also see that these software programs that really added value a few years ago are less decisive (if not different) today, on very high-end screens as is the case here. You aim for the absolute, use them. Even if your eyes don't see the difference, your mind will be at peace !

Thickness of the screen edges

They now measure 18 mm on each side and have lost 1 cm on the right and left and nearly 3 cm at the bottom. This is not a record for finesse but we are getting closer to the 2019 standards favouring multi-screens. (To be read : my advice to choose your photo monitor )

The connectivity

Nothing very original in 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 with 3 USB 3.0 plugs on the left side of the screen - see photos above). In 2019, the USB-C is missing which will be present in the CS2731 version in spring 2020.

Improved ergonomics !

Ergonomics has been significantly improved, especially for transport, since a new handle appears at the top and back of the screen, which is very practical for raising or lowering it to the right height. However, there are still no cable grommets in the foot. The amplitude of the screen's movements in height (over 5.9 inches), inclination and rotation will allow all users to find their ideal setting. Really perfect !


Ergonomics Eizo CS2730 monitor


Another new feature of the CS2730 is that the menu buttons on the screen are now electrostatic, much more elegant than on the CS270 and have a nice ringing sound (which can be cut) when clicked. A lot of refinement in this new screen...


Electrostatics buttons Eizo CS2730

The buttons on the screen menu are now electrostatic but the OSD is still the same.

Note !  In the OSD of the screen it is possible to modify the brightness of the LEDs or even turn them off for those working in the dark using the Preferences > Indicator menu. Good point !



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

I calibrated this screen - like all the screens I test - with the best current colorimeter (except the superlative and very expensive Discus) in an excellent price/quality ratio: the i1Display Pro + i1Profiler 1.7.1 software in order to be able to locate this new screen compared to the screens on the market.

I chose the following screen settings :

  • Color space : Adobe RGB
  • Gamma : Adobe RGB (2,2)
  • Gamma 2,2 (Adobe RGB)
  • Color temperature : 6500K (Adobe RGB).

And as target values in the i1Profiler software 1.6.6...  

  • Display technology : Chose white diodes,
  • 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 : Luminance: 80 Cd/m2 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 switching to Delta E, it is interesting to record the color temperature values achieved and the contrast.


Final report after calibration of Eizo CS2730 monitor with i1Display Pro


My opinion ! As by chance the color temperature (TC) is obviously very close to 6500K and not as close as on many lower end displays. The contrast is in the average of the screens using these panels. This panel is therefore different from the Eizo CG2730, which replaces the CX271 and has a double contrast. This may be the weak point of this monitor...

The Delta E figures according to the 2000 standard are obviously excellent and finally very close to the old CS270 after calibration with the i1Display Pro sensor, so without going through a hardware calibration and ColorNavigator.


Delta E after calibration of Eizo CS2730 monitor with i1Display Pro


My opinion ! My test copy offers, like all the Eizo displays of the CS series, perfect colors for a human being with excellent vision: 0.45 of average and the worst patch at 1.39 according to the 2000 standard. This new Eizo CS2730 is therefore in line with what can be expected from an Eizo ColorEdge display !

Now harmonizing tests in luminance and color temperature:

  Once again, these are amazing readings ! You want to see what a homogeneous panel is and get a loan or buy this Eizo CS2730! I only saw this on the Eizo CG277 tested on this site.


Uniformity temperature color after calibration of Eizo CS2730 monitor with i1Display Pro

In color temperature, it's just as impressive on my test copy. So few 27-Inch do so well. I've rarely seen that in this size ! Well done, Eizo.

What about subjective data : what does my eye see ?

First of all, it should be noted that there are very few light leaks in the dark. This is changing! So many screens sometimes have large light leaks. 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 a picture.
Then, the Eizo CS270/CX271/CG247, which shared the same panel, were references in terms of quality of display of colors, grays, shades, subtleties in saturated colors, in the display of shadows, in the uniformity, in everything you want! The panel of this new Eizo CS2730, although different from the magnificent Eizo CG2730, which has a doubled contrast (1500:1 instead of 680:1), is equal to it in terms of colour and it is difficult to separate them 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 to calibrate Eizo from the ColorEdge series !

  I like it very much...  
  • "Perfect" values in practice after calibration,
  • New IPS matt panel with a superb finish,
  • Wide range for photographers (Adobe RGB),
  • Thin edges, on all sides: 18 mm instead of 28... finally!
  • Updated connectivity (USB 3.0),
  • Ergonomic design noticeably improved (very convenient handle, electrostatic buttons, rotation)!
  • 5-years warranty,
  • Long service life (in principle no planned obsolescence),
  • A real crush product !
  I regret...  
  • No hood's the only "negative" point I see....
  • Looking carefully, I might say the slight lack of contrast with the CG2730.
  My overall rating...  
  9,5 / 10  
  My conclusion...  
No reason to deny it : the Eizo monitors of the CS series are really different ! What a pleasure to test such monitors. Even in 27'' Eizo can make homogeneous panels. You really should add the extra $300 compared to the competition, you won't regret it. I assure you.
So why "only" 9.5/10? Just to leave 10/10 to the Eizo CG2730 which offers a double contrast. Because for the other aspects, this Eizo CS2730 is only perfect at only $1,267 ! Yes I assume, at only $1,267.
