Eizo ColorEdge CX241 monitor review

EIZO CX241 monitor The Eizo CS240 already displays perfect colors and has a perfectly homogeneous panel. What does the Eizo CX241 add since it shares the same panel? A screen under regular monitoring thanks to a built-in calibration device - which doesn't enable to perform a calibration though! - and a few functionalities related to the hardware calibration program, ColorNavigator, which enables to offer a very strict checking of the screen/paper graphic chart, for instance, or to reassure your client regarding the fact that your screen respects the last ISO norms. This monitor is thus more specifically aimed at graphic designers and professional photo editors than at photographers. That's my opinion, at least!

In the ColorEdge range, the CX241 is the intermediate solution between the CS240 and the top-range CG247 (in 24-inch of course!). It is thus a 24-inch monitor, with the same panel as the CS240, (1,920x1,200 - pitch 0.27 - 94 ppi) but which is aimed at very rigorous photographers and other graphic designers who work for others, because its new-generation glossy panel, with IPS technology (white LEDs), 16 bits LUT table and wide gamut hence covering a gamut very close to Adobe RGB 98 is under more surveillance than its little brother thanks to a built-in calibration device. It is sold over £1,000 (at June 2016) hence £400 more than its little brother...

New ! The CG2420 replace the CX241 from May 2016

Among the new features, which are quite many and always welcome:

  • The panel is still an IPS matte panel but with a contrast ratio of 1500:1 thanks to a new filter, hence deeper blacks,
  • Still 1920 x 1200 displaying Adobe RGB 98 (photographers) and DCI-P3 (video makers),
  • but thinner edges: -1 cm on each side for a tighter multi-screens configuration,
  • Electrostatic buttons on front,
  • "Real" built-in calibration device, as on the CG247 and still with Colornavigator + cap!
  • HDMI, DVI and DisplayPort + USB 3.0 inputs!

Bulkiness and perceived quality

This monitor has a 24-inch panel and is 58 cm wide. It is bulky for a 24-inch. As for perceived quality, it is really excellent. Nothing more to say.

The monitor and its panel

Ecran Eizo CSX2411 - Definition/resolution - It is the same panel as the CS240 hence a glossy IPS panel, normal for this range of screens called "Graphic Arts", of 1,920 x 1,200 pixels. Its resolution is thus 93.8 ppi. Classic and not "Retina" but guess what, thanks to the superb anti-reflections treatment I will mention again later, pixels seem almost invisible from a "normal" viewing distance at your desk (24''/60 cm). Very beautiful. The backlighting is white-LEDs type.

2 - The panel and its anti-reflections treatment - I've noticed that for a little time and very noticeably on this screen, a "glossy" anti-reflections treatment doesn't mark the pixels anymore, which gives to this panel an awesome rendering for images and gradients. Very beautiful. Anti-reflections treatments that gave the pixels a grainy air are now over. Phew!

3 - Hardware calibration program - This monitor is sold with its calibration program: the famous ColorNavigator – It guarantees you an ideal and above all easy calibration, for those who don't master the meaning of all target values. But it is especially this program, coupled to the built-in calibration device, that will enable you to check on your screen on a regular basis. I'm coming back to it a few lines below.

Automatique hardware calibration4 - Built-in calibration device - This tiny built-in calibration device, which only measure a bit more than a centimeter when it gets out of its hideaway at the top of the screen, will measure white point and brightness of the screen at the time of the "real" calibration performed with another sensor and will, automatically, according to a period that you previously determined - 200h by default hence an average of 20 days for a professional - will measure this white point and brightness again at the top of the screen, of course, where the calibration device is, in order to check that the screen hasn't moved regarding these two values.

Thickness of the edges of the screen

They're 27 mm thick so we're in the presence of a bulky screen, not ideal for multi-screening. (Read: my recommendations to choose your monitor for photography )

Ergonomics (see photos above)

Ergonomics are classic but a wire grommet on the foot would be welcome! The range of motion of the screen in height (on 13 cm), in tilting and rotation, will enable all users to find their ideal setting. Really perfect! The menu buttons on the screen are classic, not too elegant though but it is obviously a detail.

What is it like after calibration?

I calibrated this screen with the best sensor currently on the market in a first time (except the superlative and very expensive Basic), of excellent value for money: the i1Display Pro + program iProfiler (version 1.6.3). You'll see that the figures are already almost unbelievable, coincidentally very close to the CS240 (well, well!) so it could only be better with ColorNavigator but I'm afraid you won't be able to see a difference even if the figures are even better. And at this level, you don't find uncertainties of measurement due to the sensor or the program. I'd like to remind you that a sharp eye can see a gap of 1/200. We're talking about average gaps of 1/400 here!

I chose these monitor settings:

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

And as target values in the program...

  • Screen technology: choose white LEDs,
  • D65 or possibly a bit less if you want a screen that is a bit warmer. (Note that at D55, the screen tone is really warm but not yellow as on low-range screens),
  • Luminance: 80 Cd/m2 or more depending on the main use you have of your screen (print or web) and above all depending on the brightness of your room,
  • Contrast: Native or 287:1 (for those of you who print a lot),
  • Gamma at 2.2 – standard curve, (the L* is only available with ColorNavigator and there's a lot to say about this "gamma" anyway)
  • ICC norm: V2 (to avoid incompatibility problems with certain image viewing programs (images too dark) and of course V4 if you know what you're doing.

And the result is?

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

Delta E figures (2000 norm) are of course exceptional and furiously alike those of the CS240 (They share the same panel) widely under 1 - 0.53 -, even for the patches that are the furthest from the ideal. It is already better than perfect. If you want perfection invisible to the naked eye, try ColorNavigator but I'm afraid you're going to be disappointed. At this level, getting better results in figures will be tricky because of uncertainties of measurement of the sensor and above all, you won't see any difference to the naked eye unless you're some kind of Superman.


Delta-E  final report of Eizo CX241


My opinion! As expected, the panel gets the same type of Delta E as the CS240, superlative as well, to the point that a calibration with ColorNavigator won't bring you anything more regarding this criterion. However, ColorNavigator performs a calibration called "Hardware" where the ICC profile is directly injected into the 16-bits LUT table in order to guarantee even smoother color gradients (on paper at least). Practically speaking, it is already so good with this brave i1Display Pro! Even if I used proprietary software for calibration because they improved the values significantly, I think that with this new generation screens, or at least Eizo ones, the gap, when it exists, remains absolutely invisible to the naked eye. That's what we call progress!


Perform a hardware calibration?

For perfection addicts, I recommend to calibrate your screen in hardware mode using ColorNavigator, meaning:

1 - Plug in the USB 2.0 wire sold with the screen,
2 - Reset the colors of your screen and pick Mode: Calibration 1 or 2,

3 - Follow the usual calibration process in ColorNavigator: D65, 80 or 100 Cd/m2, Native contrast, gamma 2.2, maximum number of colored patches.

At the end of the calibration process, the profile is directly sent into the LUT (16 bits) of the screen for better color gradients. .. theoretically.

grey degraded most beautiful with hardware calibration... in théory !

When you introduce it this way, any photographer would want hardware calibration! On new generations of screens, it is just "a little bit less" spectacular... and even trivial sometimes. You will only get such a poor result on very low-range screens nowadays. But marketing has gone this way...

Let's now see harmonization tests for luminance and color temperature:


Luminance uniformity of Eizo CX241 monitor


Once again, this is superlative data!


white point uniformity of Eizo CX241 monitor


Color temperature follows the same path of course: a maximum gap of 36K! All of this is incredible...

And my subjective data: what does my eye see?

The CS240 was a reference in terms of quality of color display, greys display, subtlety in saturated colors, shadows display, uniformity, and so on. The CX241, as a coincidence, does exactly the same... but it doesn't do better! The so-called selection on the line to pick only the best numbers for the CX and CG doesn't really show. It is still perfect, as I was telling you, but with the comfort (?) of a regular automatic check of brightness and white point. All things considered, why not perform a real calibration on a regular basis? Oh, that's just what you can do with the CG247!




Conclusion and my rating!

Eizo CX241I would willingly admit to you that I don't know who I could recommend this intermediate screen in the ColorEdge range to... It is obviously perfect from a colorimetric point of view, just like its little brother CS240. It is supposed to be selected more carefully on the production line and it brings in a built-in calibration device, but one that only enables to make a regular check of brightness and white point (hence not a "real" thorough calibration and this automatically. And no, it won't keep you from buying a sensor!!! You might as well buy the CS240 + the i1Display Pro for less than £900.00 and you will re-perform a real calibration at a regular frequency. If you want this last functionality to be automatic, you still have the possibility to buy the absolute top of the basket for Eizo, the CG247, which does include a full calibration sensor, all possible warranties and the additional cap. If you want to hunt data, let's do it completely!

  • Record figures after calibration: average Delta E of 0.23 and maximum gap of 0.53 (norm 2000) while it is extremely difficult for the eye to see a difference under 1!
  • Perfect colors!
  • Neutral greys that are really neutral!
  • "Glossy" matte IPS panel with a perfect rendering, smooth without the grainy effect of older generations,
  • wide gamut (Adobe RGB 98) ,
  • Built-in calibration device but...
  • It can't be used for calibration, just to check white point and brightness from time to time...
  • Bulkiness,
  • £350 more than the CS240!
  • Just because I like quibbling: texts are even sharper on the BenQ PG2401PT.
9.5 / 10... I'll save 10 for the CG247!


My opinion: What more than CS240 does this CX241 have? The possibility to check calibration from time to time - with a programming - thanks to a built-in calibration sensor. But it doesn't enable to perform said calibration. You need to own a sensor absolutely. Dubious. It is the privilege of the CG247, even better, still with the same panel. So who is it aimed at? If you want a monitored screen, you might as well buy the CG247, its "real" built-in calibration sensor, its cap and all the warranties offered by the top of the ColorEdge serial... It's what I think!
