EIZO CG319X monitor review


Eizo ColorEdge CG319X monitor review

Published on July 16, 2019   |  Updated on May 07, 2020


This Eizo CG319X screen is at the top of the Eizo monitor hierarchy. On paper, it is the best screen in the range: 32 inches, "real" 4K, Adobe RGB, Rec2020, HDR with the highest Eizo standards. To this you add an automated internal calibration and its validation by all current certifications (ISO 12646 standards). It looks like the best monitor possible.... Quite simply.

But who is this perfect screen for?! To everyone would I be tempted to say... if you have a well-filled bank account or a big activity!  To be more precise, I would be tempted to tell all photographers, retouchers and videographers who are looking for the best and most relaxing - in the sense that we no longer need to ask ourselves questions about the quality of the display of our images or videos - screens if their activity allows them this heavy investment because they have an ideal specification (32 inches, True 4K, all color spaces photo and video, HDR, double contrast compared to the previous generation ,built-in colorimeter, this Eizo CG319X adds control and validation after calibration according to all current standards. In a professional context, this may not be a detail.


In a few words...


Eizo CG319X


Perfection in 32 inches / 4K has a price: more than $5,000 but what a monitor! - Read my conclusion

Introduction to the Eizo CG319X

Here to start with some illustrations of this screen with its flawless ergonomics... and surely the best quality of manufacturing that I have seen pass before my admiring eyes, like the latest creations of Eizo by the way (since 2018)!

The monitor is sold with:

  • The power cord.... of course!
  • The hood
  • A DisplayPort to DisplayPort cable,
  • An HDMI to HDMI cable,
  • A USB 3.0 cable for hardware calibration and powering the USB 3.0 HUB.
  • ColorNavigator on CD

Note about the content!   This Eizo CG319X has an excellent built-in colorimeter that you will use with the ColorNavigator software sold with this screen.

The size and perceived quality

The display has a 31.1" panel and is 737 mm wide (the panel is 698 x 368 mm). It is therefore a rather cumbersome screen that does not especially favour a multi-screen working environment, but is it useful with such a large screen size?

EIZO CG319X monitor

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: 78 mm of electronics!

The Eizo CG319X screen and its new generation panel

1 - Definition/Resolution - This is a hand-picked matte IPS panel (without glare) since it is a Class A panel, normal on this slot of screens called "Graphic Arts", 4096 x 2160 pixels, therefore displaying the "real" 4K and not only the UHD (3840 x 2160). Its resolution is 148 ppi. It is obviously a display close to perfection. The backlight is a white LED diode type.

2 - The panel and its anti-glare coating - I notice that recently and clearly on this screen, the " matt " anti-glare coating no longer marks the pixels, which gives this panel a magnificent rendering on images and gradients. Very beautiful and frankly, it's perfect.

3 - 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 calibrator -This very small 3 cm long calibrator, located 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 with validation according to the latest current standards and this possibly automatically, at a frequency you have defined - 128 h by default or 12 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 advice! 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 3 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 128 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!

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

  • The 3D Look Up 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 (60 Hz frequency)
  • Overdrive function for a smooth video display (equivalent to a response time of 9 ms).
  • For video post-production - I/P conversion
  • For video post-production - HMDI: 1080 to 24 frames/sec.

Frankly, these illustrations are at the limit of caricature because they exaggerate so much on the breaking of tones but this makes it possible to show "more or less" what is happening...


6 - Gamuts - All the 2019 photo and video gamuts are available in direct access in the OSD menu of the screen:

Important note!  Warning of out-of-range values of an image - New CG319X

It is possible to activate a function that warns areas of an image that exceed this or that gamut but, as in Photoshop, it has an impressive side and therefore not always very fine because we do not know if we exceed this or that gamut by 1% or 20% what is there, much more embarrassing. This is what I call a good idea that is not well implemented and does not help in understanding gamut overruns. Indeed, on the picture below in the center, almost all the rose seems to be out of gamut gold if it is for less than 5%, I wish you courage to see this "loss" of gamut and therefore of saturation.


Warning of gamut overruns on the Eizo CG319X screen


This screen has all the connections you would expect in 2019, with the notable exception of a USB-C connection. We will find a Display Port 1.2 connector, an HDMI connector (with direct connection to a digital camera or a video camera), a USB 3.0 connector to guarantee hardware calibration, i.e. send the ICC profile generated by ColorNavigator directly to the LUT table on the screen and not only to the graphics card and finally three USB 3.0 connectors...


Connectivity of the EIZO CG319X

ColorNavigator software

My recommandation!   Even if the calibration with the i1Display Pro is very efficient as you will see below, the interest of this monitor lies, among other things, in its integrated colorimeter + ColorNavigator. It happens to be perfect and even a little better than my favorite probe, 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 not only allow you to perform an "ideal" calibration but also to check that it complies with the various current standards, especially those used by printers - FOGRA CERT - or video editors - REC 709, REC 2020 or DCI-P3. This guarantees you an ideal and above all easy calibration for those who do not master the meaning of all target values.

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.

Thickness of the screen edges

They measure 16 mm (compared to 27 mm on the CG277) so we have to deal with a display with clearly reduced but still thick edges in 2019 where we see many displays blooming whose edges measure between 5 and 10 mm only! This does not especially favour multi-screens but do we necessarily need them in 32 inches, 4K moreover? (Read my advice to choose your photo monitor photo )

Ergonomics (see photos above)

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 CG319X screen worth after calibration with the i1Display Pro or ColorNavigator?

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 1.8.3). 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 + ColorNavigator, which is 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, 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. We are talking on average here about 1/400 or even 1/600 deviations!

I chose the following settings :

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

And as target values in the i1 Profiler 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,
  • Contrast: 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 the calibration is complete, the color temperature of the white point reached is 6488 K, the luminance of the black is only 0.068 cd/m2 so very deep, especially compared with the 0.11 cd/m2 of the previous generation (Blacks are twice as deep). The measured native contrast is also 1324:1 compared to the 710:1 of the previous generation.


Final report after calibration of the Eizo CG319X with the i1Display Pro


1 - Delta e - The delta E figures (Standard 2000) are obviously exceptional, well below the value of 1 since I found a record value of 0.26 for the average and 0.81, even for the most remote patches from the 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. This value for the highest patch is therefore to be taken with caution. So it's already almost perfect with this calibration solution. You will see that with ColorNavigator you only get an improvement of the grays and blacks.

Maintaining uniformity tests in luminance and color temperature:

1 - Luminance uniformity - While many displays in 2019 achieve sufficient luminance uniformity at 255 levels, this is very often not the case at lower levels (127 and 63). This is obviously not the case with this Eizo CG319X, perfect again because it does not exceed 5% at L127!

Once again, these are superlative readings: 0% at L63 on a 32'' panel!

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 a little less spectacular since there can be a delta difference of 1.4 ! On a 32" it's simply incredible...



Calibration with the built-in colorimeter and ColorNavigator software

The Eizo CG319X 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 i1 Display Pro (in this test with my personal sensor) - is controlled by the ColorNavigator software provided with the display. This software is a benchmark for its performance and control capabilities once calibration is completed. I therefore recommend it to you without reservation.

Warning! To be able to calibrate your Eizo CG319X 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.

EIZO CG319X display and its built-in colorimeter

1 - Calibration programming

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 Eizo CG319X's very short heating time - 7 minutes - would not leave the screen 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. For professional use, I recommend a monthly calibration, just to be really, really reassured!

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 despite the fact that it now passes 134 colorful patches and not 32 as on the old generation of Eizo ColorEdge displays.

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

Once the calibration is finished with ColorNavigator, the color temperature of the white point reached is 6497 K, the luminance of the black is only 0.06 Cd/m2 so as with i1 Display Pro and the measured native contrast is 1434:1, again very close to the i1 Display Pro and more than doubled compared to the previous generation of ColorEdge.



The Delta E according to the 2000 standard gives an average value of only 0.27 on all 134 patches as i1 Display Pro and a maxi of 0.90 also as with the i1 Display Pro. The integrated colorimeter + ColorNavigator matches the i1 Display Pro and i1Profiler, except in grey neutralisation, which is even more accurate with ColorNavigator. However, 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 grey neutralisation is perhaps even more neutral with the ColorNavigator solution than the grey scale test is even more progressive but really because there has to be a winner! The real winner is the ease of use thanks to the programming of this integrated solution and the validation according to the ISO 12646 standard, impossible with i1 Display Pro. If perfection is to have a name, it will be this Eizo CG319X!
