EIZO CG2730 monitor review


Eizo ColorEdge CG2730 monitor review

Published on October 22, 2019  |  Updated on May 10, 2020


This Eizo ColorEdge CG2730 screen is located in the middle of the Eizo ColorEdge screen hierarchy, at the very top of the Eizo range. But what does it offer more than the Eizo CS2730 and less than the Eizo CG279X?
In short, it is a bit like taking an Eizo CG279X and removing the possibility of obtaining a report after calibration and certifying it according to this or that standard in force. What if it could still be suitable for as many photographers, graphic designers or video artists as possible?

But who is this "mid-range" screen for in the top-of-the-range Eizo?! Why "only" choose this Eizo CG2730 over the Eizo CG279X? Well the answer is very simple: the panel is the same as on the Eizo CG279X with its built-in colorimeter and visor but you will no longer have access, in the ColorNavigator software that comes with it to calibrate this screen, to the calibration report, validation and certification tab of the said calibration. Is this embarrassing? For the vast majority of us, not at all! Have a good reading...

What's in the box...

The monitor is sold with...

  • The power cord... of course!
  • The shading hood,
  • A DisplayPort to DisplayPort cable,
  • A DVI to DVI cable,
  • A USB 3.0 cable for hardware calibration and powering the USB 3.0 HUB,
  • ColorNavigator on CD,
  • A screen cleaning kit.

Note about the content!  This Eizo CG2730 has an excellent built-in colorimeter that you will use with the ColorNavigator software sold with this screen (see below).

The size and perceived quality

The display has a 27" panel and is 637 mm wide (the panel is 598 mm wide). It is therefore a "normally" cumbersome screen, thus promoting a multi-screen working environment  

EIZO CG2730 screen and its colorimeter + shading hood

As for the perceived quality, it is excellent, really. In Eizo's top-of-the-range standards and therefore in worldwide production. Just look at the profile screen to understand that the screen is really under control as it is so thick: 7.8 cm of electronics!

The Eizo CG2730 display and its new generation panel

1 - Definition/resolution - This is a matte IPS panel (without reflection) selected on the hand since it is a class A panel, normal on this slot of screens called "Graphic Arts", of 2560 x 1440 pixels therefore displaying the QHD definition. Its resolution is 108 ppi. It's classic in 27 inches. The backlight is a white LED diode type.

2 - The panel and its anti-reflective coating + shading hood - I notice that recently and clearly on this screen, the matte anti-reflective coating no longer "marks" the pixels at all, which gives this panel a magnificent, almost "silky" look on images and gradients. Beautiful and frankly, it's perfect! In my opinion, this is a striking quality of the latest high-end Eizo models and this Eizo CG2730 is one of them.

Note about the content! The Eizo CG2730 is sold with its custom hood.

3 - Brightness and homogeneity with the DUE function - This very efficient function which acts as an equalizer ensures a homogeneous display with differences not exceeding 5% actually measured by my sensor. In other words, invisible or just like that!

Edge thicknesses of the Eizo CG27304 - Edge thickness - From now on, they measure only 18/19 mm whereas they measured 28 mm on the previous series. This is not far from the 2019 records (below 10 mm) but it is more conducive to a multi-screen configuration  

5 - The built-in calibrator - This very small calibrator, barely 3 centimetres long, integrated at the top of the screen, in the center, which works in conjunction with the famous ColorNavigator software provided with the screen and detailed below, will allow you to perform a perfect calibration and this eventually automatically, according to a frequency you have defined (200 hours by default or two weeks on average for a professional). You can still perform a calibration with your favorite colorimeter but this colorimeter is perfect and the calibration is very fast.

My recommendation! It is therefore possible to program the calibration at night to find yourself the next morning in front of a screen that is always perfect. The screen will then turn on by itself and preheat for 7 minutes. This is the time it takes for this new generation of displays to be perfectly at the right temperature, whereas a few years ago it took at least half an hour... You will perform a calibration every 200 hours and that will be perfect. On the one hand, the new displays are very stable because they heat much less than the CRT displays so they do not need to be calibrated very often and on the other hand, this display allows you to program your calibration when you are not using it, so no matter how fast you program!

6 - Gamuts - The Eizo CG2730 displays 99% of Adobe RGB, 98% of DCI-P3 and 100% of sRGB. The Adobe RGB and sRGB spaces have direct access from the OSD menu on the screen. From classic to high-end in 2019 but not including, as on the Eizo CG319X, all video gamuts (REC2020 for example, for broadcast). However, Rec 709, which is close to the sRGB, is also well included. Photographers who are not reluctant to make content for Youtube will not be limited because the "color space" of Youtube is REC709.


This screen has all the sockets you would expect in... 2018 but now the USB-C with 60W recharge is missing for a laptop in 2019! We will find a Display Port 1.2 socket, an HDMI socket, a DVI-D socket, always as powerful as ever, and finally a USB 3.0 socket to guarantee hardware calibration, i. e. to send the ICC profile generated by ColorNavigator directly to the Look Up Table on the screen and not just to the graphics card. Finally, you will find three accessible USB 3.0 sockets on the left side of the screen.

ColorNavigator software

My advice!  Even if the calibration with the i1Display Pro is very efficient as you will see below, the interest of this screen lies, among other things, in its built-in colorimeter + ColorNavigator. It happens to be perfect and even a little better than my favorite sensor, especially in grey neutralization. I highly recommend the use of the integrated colorimeter which can only work with ColorNavigator!

This screen is sold with its calibration software, the well-known ColorNavigator which works in conjunction with the built-in calibrator. This high-end software will allow you to perform an " perfect " calibration without being able to check it at the end of the calibration. For that it is necessary to buy the range above i.e. the Eizo CG279X.

Ergonomics (see pictures below)

The ergonomics is classic + ! The amplitude of the screen's movements in height (over 150 mm), inclination and rotation will allow all users to find their ideal setting. Really perfect! The menu buttons on the screen are electrostatic.

What is the Eizo CG2730 screen worth after calibration with the i1Display Pro or ColorNavigator?

First, I calibrated this screen with the best current colorimeter (except the superlative and very expensive Discus - about 1000 dollars) in a simply excellent price/quality ratio: the i1 Display Pro + i1Profiler software (version 3.1.1). This allows you to compare this screen with the other screens on the market even if it is very clear that I strongly advise you to use the integrated colorimeter + ColorNavigator, even better, especially in the neutralization of grayscales. You'll see that the numbers are already barely believable, so it could only be better with ColorNavigator but I'm afraid you won't see the difference anymore. And even though at this level, we do not find ourselves in the uncertainty errors of the sensor or/and the software. I would remind you that a very efficient eye distinguishes 1/200 of a difference. We are talking on average here about 1/400 or even 1/600 deviations!

I choose the following screen settings:

  • Color space: Adobe RGB
  • Gamma : Adobe RGB (2,2)
  • Color temperature: 6500K
  • 90Cd/m2.

And as target values in the i1Profiler software...

  • Display technology: White diodes is selected automatically,
  • D65 or possibly a little less if you want a slightly warmer screen. (Note that at D55, the screen is really hot but never yellow as on low-end screens),
  • Luminance : 90 Cd/m2 or more depending on your main use (90 Cd/m2 Web to 120 Cd/m2 print) and especially the brightness of your room,
  • Contraste : Native for the Web or 287:1 for those who print a lot,
  • Gamma at 2,2 – standard curve, (The L* is only available with ColorNavigator and there is a lot to say about this "gamma" which will make the dark parts very bright, too bright...)
  • ICC standard:V2 (to avoid incompatibility problems with some image viewing software (images too dark) and obviously V4 if you know what you are doing.

And the result is?

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

Once calibration is complete, the color temperature of the white point reached is 6498 K, the luminance of the black is only 0.076 Cd/m2 - the blacks are very deep -, especially compared to the 0.11 Cd/m2 of the previous generation (the blacks are twice as deep). The measured native contrast is also 1184:1 compared to the 610:1 of the previous generation. Really excellent!


Final report after calibration of the Eizo CG2730 with the i1Display Pro


1 - Delta e - The figures for delta E (Standard 2000) are obviously excellent - without being exceptional either -, well below the value of 1 since I have found a value of 0.66 for the average and 1.54, even for the patches furthest from ideal, only in grey values by the way. This shows that i1 Display Pro promotes a slight warming of the display unlike ColorNavigator which will be perfectly neutral. So it's already almost perfect with this non-proprietary calibration solution.


Delta E after calibrating the Eizo CG2730 with the i1Display Pro

Maintaining uniformity tests in luminance and color temperature:

1 - Luminance uniformity - If many displays in 2019 achieve sufficient luminance uniformity at 255 level (so in my case at 90 Cd/m2), this is very often very different at lower luminance levels (20 and 4). This is obviously not the case with this Eizo CG2730, perfect here again, because not exceeding 5% at L127 so you might as well say it almost invisible!


Luminance uniformity at l255 after calibration of the Eizo CG2730 with the i1Display Pro

Luminance uniformity at L127 after calibration of the Eizo CG2730 with the i1Display Pro

Luminance uniformity at L63 after calibration of the Eizo CG2730 with the i1Display Pro


Once again, these are superlative readings: 0% at L63 on a 27-inch panel! You can really edit dark photos on this screen without having any problems of uniformity. This changes my 25% deviation values quite often - too often! - identified.

2 - The uniformity of the white point:


Color temperature uniformity after calibration of the Eizo CG277 with the i1Display Pro


In color temperature, it is less spectacular since there can be a delta e difference of 2.1 (or 250 K) but to say that this is visible is a little exaggerated!!!



Calibration with ColorNavigator

The Eizo CG2730 screen eliminates the need to purchase a colorimeter because it integrates one in its upper middle section. It will come out of its small hatch when the calibration request is made. This excellent colorimeter - even better than i1Display Pro (in this test with my personal sensor) - is controlled by the ColorNavigator software provided with the screen. This software is a reference in terms of its performance and control capabilities once the calibration is completed... if you use the Eizo CG279X because this validation and the final report are only accessible on the latter. To put it another way, your calibration is excellent but nothing tells you that! I therefore recommend it without reservation despite this software restriction on this Eizo CG2730.

Warning! To be able to calibrate your Eizo CG2730 with the built-in colorimeter and ColorNavigator, it is essential to connect the USB 3.0 cable sold with the display. It allows communication between your computer and the screen as well as injecting the ICC profile directly into the Look Up Table of the screen and not only to power the USB 3.0 Hub.

EIZO CG2730 display, its built-in colorimeter and hood

1 - Calibration programming

The calibration can therefore be programmed directly on the screen, in its OSD menu. It will then be done alone where, usually, we are simply warned that it will have to be done. And even louder, it can be made even when the screen is off, so at night. Calibration will therefore not interfere with working time! The Eizo CG2730's very short heating time - 7 minutes - would not leave the display unusable for long, but even it is expected if you calibrate your display at night. It will light up well 7 minutes before starting the process.


2 - A real hardware calibration

To benefit from hardware calibration and be able to use ColorNavigator, the screen needs to be connected to the computer that will at least be used for its calibration using the USB 3.0 cable provided and through which the ICC profile will pass directly to the LUT table on the screen. This brings two benefits: on the one hand, it guarantees the best possible calibration but also the possibility of installing this screen on another computer without having to recalibrate it on it.

3 - Choosing the target values

In ColorNavigator I chose in the left column "Create a new target":

  • Brightness: 90 Cd/m2 for printing use and 100/120 Cd/m2 for mainly Web/graphic use,
  • White point: 5000K for printers and 6500K for others,
  • Gamma: 2.2 (the L Star lightens dark tones too much in my opinion).

Note! It is of course possible to change a lot of target values in ColorNavigator but if you need to choose others you know why and you will know how to do it, where and which values to choose.

When everything is ready click on the button at the bottom in the middle "Calibration..." (2)

Then choose the built-in calibrator as the colorimeter and start the calibration. This one is rather fast because it now passes about thirty patches.

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

As I said, the two most important differences between this Eizo CG2730 and the Eizo CG279X are, once the calibration is complete with ColorNavigator, the final report (example below with the CG319X) and the possibility of starting the validations after calibration of your Eizo copy. Unfortunately, this is not the case with this Eizo CG2730. As I said earlier, your calibration will be excellent but nothing tells you that!


And my subjective data: what does my eye see?

Objectively, I can say that the grey neutralisation is perhaps even more neutral with the ColorNavigator solution than with i1Profiler if you have performed the two calibrations one after the other! The real winner is the ease of use of ColorNavigator thanks to the programming of this integrated solution. For the rest, enjoy yourself because the display on this screen is really classy. Personally, I'm a fan.

  I regret...  
  • No connection after calibration with ColorNavigator, it must be left to the Eizo CG279X...
  My overall rating...  
  10 / 10 ! My favorite one!  
  My conclusion...  
What a pleasure to try this product and therefore to advise it... I think that we are not far from the best value for money in 27 inch QHD as this screen is so relaxing to work serenely. A real favorite product that I hope as many of my readers as possible will be able to buy. In any case if you hesitate because of the price, I assure you, do not hesitate any more! because this Eizo will be your companion for many years.
