Yes, you can buy a 24" Eizo screen, and even a Coloredge one (synonym of quality for Eizo) for less than $700.00! Moreover, the price of the successor of the wonderful CS240 remains unchanged. But in what proportions has this new CS2420 improved? And what is it worth compared to the ultimate weapon sold by this same manufacturer over $1,500?
To quickly introduce this new Eizo screen, first of the ColorEdge series that replaces the excellent CS240, I'd say it's a 24" screen (1,920 x 1,200 – pitch 0.27 - 94 dpi) with a new-generation glossy panel, aimed at photographers and graphic designers, featuring IPS technology (white LEDs), 16-bits LUT table and wide gamut, hence covering most of the Adobe RGB 98. It can be classified in the category of «Graphic Arts» monitors. It is still sold a bit under the symbolic price of $860 (November 2016), just like the CS240.
Présentation of the screen Eizo CS2420
To start with, here are a few illustrations of this new screen of flawless ergonomic design, noticeably improved (handle, thinner edges, electrostatic buttons) compared to the CS240...

What you'll find inside the box...
The screen is sold with :
Its power cord... of course!
A DVI cable
A USB 3.0 cable for hardware calibration and to power the USB HUB.
Colornavigator on a CD
Note about the content!Like the CS240 it replaces, this CS2420 doesn't feature a built-in colorimeter so you'll have to use your own sensor or buy one. My recommendation? An i1Display Pro!
Bulkiness and perceived quality
The panel features a 24" panel and is 55 cm wide (panel is 52 cm wide). So this screen is noticeably less bulky than the CS240 it replaces. That's good news for those who want to build a multi-screens configuration!
The screen and its panel - New
1 - Definition/resolution - So it's a new glossy IPS panel, normal for this range of screens called "Graphic Arts", of 1,920 x 1,200 pixels. So its resolution is 93.8 ppi. Classic and not "Retina" but you know what, thanks to this great anti-reflections treatment I'll mention again below, the pixels seem almost invisible from a "normal" viewing distance on a desk (60 cm). Very nice anyway. The backlighting uses white LEDs, like on the old CS240.
2 - The panel and its anti-reflections treatment - New - The anti-reflection treatment of the old CS240 had marked an important step because finally, it was subtle and almost invisible on the pixels. I never complained about mine (on a CS240) and this new plate seems to have a very similar treatment, that doesn’t reach the smooth finish of the CG2420 though.
3 - Program for hardware calibration - This screen is sold with its calibration program: the famous ColorNavigator – It is supposed to guarantee you an ideal calibration, easy to perform moreover for those of you who don't really master the meaning of all target values – without a built-in sensor though. So you'll have to own a compatible sensor to be able to use it. All good then.
With that in mind, screens improved so dramatically that even with a "simple" calibration using the i1Display Pro + iProfiler, you get results that will appear perfect to your eyes nowadays. Only the figures can still be improved with this kind of hardware calibration but it's beyond our perception threshold.
Note! I can understand that brands communicate on their hardware calibration program though, because you'll be absolutely "certain" to optimize all the settings of your calibration, especially the display of grey gradients, but what I also see is that these programs that definitely added a value a few years ago are now a lot less crucial (and I'm weighing my words carefully), at least on top-range screens like this one. You want absolute perfection, go for it. Even if your eyes can't see a difference, you'll be at peace with your conscience!
Thickness of the edges of the screen - New
Now they're 18 mm thick on each side of the screen and thus lost 1 cm on the right, 1 on the left and almost 3 at the bottom. It's not a thinness record but it's getting closer to 2016 standards favoring multi-screens configurations. (Read: my recommendations to choose your photo screen )
Improved (see photos above) ergonomic design!
Ergonomic design has been noticeably improved, especially for transportation since a new handle on top and at the back of the screen has been added, also very convenient to adjust its height. Still no wire grommet in the foot though. The range of motion of the screen in height (on 15.5 cm), tilting and rotation will enable all users to find their ideal settings. Perfect really!
Other new feature, the menu buttons on the screen are now electrostatic, a lot more elegant than on the CS240 and with a nice ping (that can be muted) when you press them. This new screen is definitely really refined...
The buttons of the screen menu are now electrostatic but the OSD has remained the same.
Note! In the screen's OSD it is possible through the menu Preferences Indicator to change the brightness of the LEDs or even to turn them off for those who work in the dark. Well thought!
What is it like after calibration with the i1 Display Pro?
I first calibrated this screen – like all the screens I review – with the best current sensor (except the superlative and very expensive Discus) which is in addition great value for money: thei1Display Pro + program iProfiler (version 1.6.6) in order to be able to compare this screen to other screens on the market. The values are very similar to the CS240’s it replaces.
I chose the following screen 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 iProfiler 1.6.6...
Screen technology: Choose white LEDs,
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: 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 discussing the Delta Es, it’s interesting to point out the color temperature values and contrast values reached.
My opinion! Is it a coincidence that the color temperature is of course at 6,500K and not approaching like on lower-range screens? I don’t think so. The contrast is very close to the CS240’s while the plate was changed. This plate is thus different from the CG2420’s replacing the CX241.
The Delta E numbers according to norm 2000 are of course excellent, though not approaching the CG2420’s new record, and finally very close the old CS240’s after calibration with the sensor i1Display Pro hence without going through a hardware calibration with ColorNavigator.
My opinion! Without breaking a record but still with an average of 0.52 only, the CS2420 gets a better average score than the CS240 because the highest patch doesn’t go over 0.79. However, it is so far below the threshold of visibility for the human eye – yours, mine, anyone’s – that it’s rather symbolic. This new CS2420 is thus in conformity with what could be expected from an Eizo ColorEdge screen even if this substitute for the CS240 is only slightly better while the CG2420 and its new plate just set a new record on this site.
Let's now see the tests of brightness and color temperature harmonization:
Once again, superlative values! You want to know what a homogeneous panel is? Well borrow or buy this CS2420!
In color temperature, it is surprisingly less good: a gap of maximum 134K at the top is not neglectable! Claiming it’s visible would be exaggerate, but still...
What about subjective data: what does my eye see?
The CS240, CX241 and CG247, which all featured the same plate, were references of quality as per the display of colors, greys, gradients, subtlety in saturated colors, shadows, homogeneity, everything. The plate of this new CS2420, different from the wonderful CG2420’s, is of the same quality as the old CS240’s and it is difficult to tell them apart visually. So it’s still as good, but it’s not a good reason enough to change your screen on this sole criteria… but there’s still the design improvements.
Conclusion and my rating!
CS240 and CX241 shared the same plate, but this CS2420 indeed has a different plate from the CS240 it replaces, and also a different one from the amazing CG2420. But while the CG2420 noticeably improved the display compared to the CX241, this CS2420 is very similar to the CS240. This sole criteria wouldn’t justify un update. Now the design has been noticeably improved: the new handle is very convenient, its wirings are brand new (USB 3.0), its menu buttons are now electrostatic, hence a lot more pleasant to use, its edges are way thinner (-1cm on each side). If you already have a screen, it’s your call. But if it’s your first one, you’ll love it!
My opinion! Now should we change our CS240s for this CS2420? Probably not, except if the design improvements are very meaningful to you.
Average Delta E: 0.52!
Value for money
After-calibration data is pretty similar to the CS240 it replaces, hence not far from perfection,
New "silky" matte IPS plate with an amazing rendering even if it doesn’t improve the CS240’s,
No real improvement compared to the CS240 while the CG2420 noticeably improved the CX241,
No included cap.
9.0 / 10
My opinion: Currently, best value for money on the market, even if the only thing better about this CS2420 compared to the CS240 it replaces is its design. The new plate is indeed very similar to the old CS240’s, and maybe even slightly less homogeneous. It doesn’t benefit from the superlative plate of the CG2420, unfortunately, but the quality of display already reaches uncommon levels!
