EIZO CG247X monitor review

 


Review of the Eizo ColorEdge CG247X monitor
Published on Septembre 09, 2018   |   Updated on December 30, 2018

 

The Eizo CG2420 already displays perfect colors with its built-in colorimeter and has a perfectly uniform panel. What does the Eizo ColorEdge CG247X add since it has the same panel? A multitude of details that make it perfect, especially for professionals in photo or video editing! Quite simply.


But who is this perfect screen for?! Obviously to photographers who want the best but above all no longer think at all about their monitors or their calibration, to professional retouchers and graphic designers who must offer their customers all the guarantees of display and finally to video makers because this screen multiplies the delicate attention against them.... In the ColorEdge range, the CG247X is the perfect complement to the beautiful CS2420 and CG2420 range, and this monitor (as well as its big brother, the Eizo CG277) is for those who do not want to make any concessions on the quality of their displays and who, incidentally, want to make their lives easier by no longer having to think about calibration since it has a built-in calibrator, excellent moreover but also have all the current certifications. Here everything is just refinement, display accuracy but only a colorimeter can measure... and that's the problem: you would have a display almost as perfect with the CG2420 but without all the warranties and accessories sold the Eizo CG247X. For videographers, this is a little different: only this monitor has the functions they need to display their productions in all current video games. For about 1950 dollars, you will have an absolutely perfect color display in the Adobe RGB color space, 98% of the DCI P3, 100% of the REC 709, an equally perfect homogeneity, an integrated calibrator that can perform a calibration at night so you can free yourself up thanks to the DUE Eizo technology, a 10-bit display and a 16-bit 3D LUT table, an HDMI interface that supports I/P conversion and 1080/24fps, a 5-year warranty and many other things I'm sure. I told you it was all about refinement!

What's in the box...

The monitor is sold with:

  • The power cord... obviously!
  • The shading hood,
  • The DVI-D to DVI-D cable in 2016 is replaced by a DP cable in 2018.
  • A USB 3.0 cable for hardware calibration and powering the USB HUB.
  • ColorNavigator in CD


Note about the content! This Eizo CG247X has a built-in sensor that you will use with the ColorNavigator software sold with this screen.

The dimensions and perceived quality

The screen has a 24-inch panel and is 23.4 inches wide (the panel is 20.8 inches wide). It is therefore a rather cumbersome screen that does not especially favour a multi-screen working environment!

As for the perceived quality, it is excellent, really. Perhaps the best finish I've seen in my tests so far.... Just look at the profile screen to understand that the screen is really under control as it is so thick: 3.5 inches of electronics!

The Eizo CG247X monitor and its panel

1 - Definition/resolution - It is the same panel as the Eizo CG2420 - but hand-picked since it is class A - and therefore a matte IPS panel, normal on this slot of the so-called "Graphic Arts" screens, of 1920 x 1200 pixels. Its resolution is therefore 96 ppi. Classic and not "Retina" but who knows, thanks to the superb anti-reflective coating I talk about below, the pixels seem almost invisible at a "normal" viewing distance on a desktop (27.5 inches); Very beautiful. The backlight is a white LED diode type.

EIZO CG247X display panel

2 - The panel and its anti-reflection coating  - I notice that recently and clearly on this screen, the "satin" anti-reflective coating no longer marks the pixels, which gives this panel a magnificent rendering on images and gradients. Very beautiful. No more anti-reflection treatments that give a granular aspect to pixels. Phew!

Remark! The panel of the CG247X is the same as the CG2420 model so there is an obvious kinship.

DUE function of the Eizo CG3 - Brightness and homogeneity with the DUE function - This very efficient function which acts as an equalizer ensures a homogeneous display with differences of no more than 5% measured. In other words, invisible or just like that!

4 - The built-in sensor - This very small built-in sensor, which works in conjunction with the famous ColorNavigator software sold with the screen and detailed below, which barely exceeds 0.78 inches when it comes out of its hiding place at the bottom left of the screen, will allow you to perform a "real" calibration and this eventually automatically, at a frequency you have defined - 200 hours by default or 20 days on average for a professional. You can still perform a calibration with your favorite sensor 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 month and that will be enough. 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!

4 - The video part - The video part of this screen is really complete and represents the best in the business. Here's why:

  • The 3D LUT table manages the 10-bit input and 16-bit output for a perfect gradient display, especially if you install this screen on a 10-bit graphics card.
  • It perfectly manages 4K x 2K signals on the DisplayPort port (30hz frequency)
  • Overdrive function for a smooth video display (equivalent to a 7ms response time).
  • For video post-production - I/P conversion
  • For video post-production - HMDI: 1080 to 24 frames/sec.

The connectivity

This display has an HDMI socket (with direct connection to a digital camera or a camera), a DisplayPort socket, a USB 2.0 socket to guarantee hardware calibration, i. e. to send directly the ICC profile generated in the LUT table of the display and not only on the graphics card and finally two USB 2.0 sockets (only USB 2.0!).

The 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 sensor. It happens to be perfect and even a little better than my favorite sensor. I highly recommend the use of the built-in 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 not only allow you to perform an "ideal" calibration but also to verify that it complies with different standards used by printers - FOGRA CERT - or video editors - REC 709 or DCI. This guarantees you an ideal and above all easy calibration for those who do not master the meaning of all target values.

Colornavigator
The screenshot was taken with the CG277 but it would obviously have been the same with the CG247X.

ColorNavigator also manages other control and comparison functions between the screen and a print seen in a control booth for example and many other things.

I will create a tutorial dedicated to ColorNavigator later...

Thickness of the screen edges

They are 27 mm long so we are dealing with a screen with rather cumbersome edges, not especially favouring multi-screens. (Read: my advice on choosing your photo screen). You have to fit the colorimeter somewhere!

The ergonomics (see photos above)

The ergonomics is classic but a "real" grommets in the foot would be welcome! 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! The menu buttons on the screen are classic, not too elegant though, but it's obviously a detail.



Ergonomics of the Eizo CG277 display

 

 

 


What is the Eizo CG247X monitor worth after calibration with the i1Display Pro ?

First, I calibrated this screen with the best current sensor (except the superlative and very expensive Discus - about 1000 dollars) in a simply excellent price/quality ratio: the i1 Display Pro + i1Profiler software (version 1.6.3). 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 built-in colorimeter, which is even better, especially in the neutralization of grayscales). You will 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 even if the numbers are even better. And even though at this level, there are no uncertainty errors in the sensor and/or software. I would remind you that a very efficient eye distinguishes 1/200 of a difference. On average, we are talking about 1/400 deviations here!

I choose the following screen settings:

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

And as target values in the 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: 80 Cd/m2 or more depending on your main use (80 Cd/m2 Web to 120 Cd/m2 print) and especially the brightness of your room,
  • Contrast: Native for the Web or 287:1 for those who print a lot,
  • Gamma: 2,2 – standard curve, (The L* is only available with ColorNavigator and there is a lot to say about this "gamma" that will make the dark parts very bright, who said too bright?!.....)
  • ICC norm: V2 (to avoid incompatibility problems with some image viewing software (images too dark on Windows 10) 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 the calibration is complete, the color temperature reached is 6525 K, the black luminance is only 0.08 Cd/m2 so very deep. The measured native contrast is directly related and a value of 1207:1 is measured, which is 50% higher than on the first generation CG247. Personally, I prefer a ratio of 287:1 for a better screen-to-shoot comparison.

 

Final report after calibration of the Eizo CG247X with the i1Display Pro

 

The figures of delta E (Standard 2000) are obviously exceptional and furiously similar to those of the CS240 or the CX241 (They have the same panel... in smaller size obviously!) well below the value of 1 - 0.71 -, even for the most distant patches from the ideal. It's already more than perfect. You will see that with ColorNavigator you don't get better results already perfect! At this level it will be difficult to obtain better results in numbers because of the uncertainties of reading the sensor and especially, you will not see any difference with the apple of your eye unless you are Superman.

 

Delta E after calibrating the Eizo CG247X with the i1Display Pro

 

My opinion! As expected, the panel achieves scores worthy of the highest quality displays, so much so that calibration with ColorNavigator will not provide you with anything on this criterion. On the other hand, ColorNavigator and especially the built-in calibrator allow a better grey neutralisation and it allows to perform a "Hardware" calibration where the ICC profile is directly injected into the 16-bit LUT table of the screen in order to guarantee even smoother color gradients (on paper at least) and obviously a calibration of the screen even installed on another computer. In fact, it's already so good with this brave i1 Display Pro!

Now let's see the tests for harmonization in luminance and color temperature:

 

Luminance uniformity after calibration of the Eizo CG247X with the i1Display Pro

 

Once again, these are superlative readings: less than 1%!

 

Color temperature uniformity after calibration of the Eizo CG247X with the i1Display Pro

 

In color temperature, it is just as perfect or just as perfect because I challenge you to see a difference of 75 K.

 

 

Calibration with the built-in colorimeter and ColorNavigator

The Eizo CG277 monitor dispenses with the purchase of a colorimeter because it integrates one in its lower edge. It will come out of its small hatch when the calibration request is made. This excellent colorimeter - even better than i1 Display Pro (in this test with my personal sensor) - is controlled by the ColorNavigator software sold with the screen. This software is a benchmark for its performance and control capabilities once calibration is completed. I therefore recommend it to you without reservation.

   
Integrated colorimeter of the EIZO CG277 display
   
 

1 - Programmation of the calibration

The calibration can therefore be programmed. It will therefore be carried out alone where, usually, we are simply warned that it will have to be done. And even louder, it can be made even screen off so at night. Calibration will therefore not interfere with working time! The very short warm-up time of the Eizo CG277 - 7 minutes - would not leave the screen unusable for long. For professional use, I recommend a monthly calibration, just to be really, really reassured!

 


2 - A real hardware calibration

To benefit from hardware calibration, the display needs to be connected to the computer that will at least be used for its calibration using the USB 2.0 cable provided and through which the ICC profile will pass directly to the LUT table on the display. 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 - Choose the target values

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

 
 
  • Brightness: 80 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 brightens too much the dark tones).


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 top right "Adjust" (2)

Then choose the built-in calibrator as the colorimeter and start the calibration. This one is rather fast because it only reviews 32 patches.

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

Once the calibration is complete, the CT reached is 6504K, the black luminance is only 0.13 Cd/m2 so very deep and as with the i1 Display Pro. The measured native contrast is 623:1, again very close to the i1 Display Pro.

 

 

Delta E according to the 2000 standard gives a low value of only 0.1 and maxi at 1.07 on all 32 patches in saturated yellows. The average is 0.38. So on ColorNavigator paper and the built-in colorimeter are equal with the i1 Display Pro and i1Profiler. Those who wanted to know the difference between the two now know!

And my subjective data: what does my eye see?

Objectively, I could say that the neutralization of the grays is perhaps even more neutral with the ColorNavigator solution than the grayscale test is even more progressive but really because he has to be a winner! The real winner is the ease of use thanks to the programming of this integrated solution.

From 2002, this Website offers...
 

This site dedicated to color management for photographers and videographers, beginners or professionals, visited by more than 330,000 people last year, offers on the one hand to help you easily understand and put into practice the color management of your photos and on the other hand helps you make the best investments with more than 100 hardware or software reviews since April 2002 in French and 2014 in English! It is the result of a patient work and a long experience shared by a professional but above all passionate photographer !

 

Where do the tested products come from ? Is my opinion completely independent ?

All the products I talk about on this site have been tested by me either following a personal purchase, a friendly loan, during a training session at a customer's site or after a manufacturer's loan.
they thank me for the precision of my remarks which will help their future products to progress. So things are moving and my impartial opinion is more and more appreciated.... If I believe your emails, your trust marks and even some brands.

 

You often ask me how this site is financed since its content is free...

Here is how I have been doing, historically since 2002, to make it easier for you to contribute: the affiliation and sale of my PDFs (in French).

Here's how affiliation works. Each time you click on the links on this site to my partner shops, for example from my test pages or on the thumbnails on the right, they know that you come from me (thanks to a piece of code in the link) and give mea small percentage on the whole of your basket (my advice of purchase as well as all your purchases in this shop). Nothing prevents you from thinking about my site when you buy from these online stores even if you don't want to buy a monitor or a colorimeter!

 

... And how to participate!

So my proposal when you don't know how to thank me for the free content: think about using my links to buy in these different partner shops because they play the game!
