A great 24" monitor complete with inbuilt calibrator - perfect for all serious image makers!
The Eizo CG2420 monitor is the next step up from the popular CS2420, featuring the same quality panel as in the benchmark CG series. It offers better brightness stabilisation and uniformity meaning the monitor is ready for professional work more quickly, and the field of display is more even. It also comes with an inbuilt calibrator! The in-built sensor is not quite the same as that in the CG247 model which provides better dark tone separation, but this model offers a lot of the CG247 performance at a reduced price.
This monitor can wake itself up in the middle of the night, self calibrate, and put itself back to bed all with no user intervention at all!
As with the rest of the ColorEdge Range, the CG2420 has a wide gamut display, which allows the monitor to display a much wider range of saturated colours (almost all of AdobeRGB), and this is perfect for all serious image makers. The CG2420 is a complete package which includes the monitor, hood, stand, cables, in-built calibration sensor and ColorNavigator software. It features a new slim, stylish design with a bezel 39% slimmer than the CG247.
About the CG2420, Eizo say:
The ColorEdge CG2420 can be summed up as hassle-free maintenance and optimal colour reproduction for professionals in photography, design, print, and post production to express their vision.
It features a built-in self-calibration sensor for hassle-free monitor maintenance, vivid colours reproduced to industry standards, and exceptionally high contrast for producing true blacks.
Built-In Sensor to Automate Your Workflow
Automate your calibration with the sensor that is housed within the front bezel. The sensor swings onto the screen when calibrating, eliminating the need for a third-party device. It works when the monitor is in portrait mode too!
Vivid Colours Reproduced to Industry Standards
The wide colour gamut of the ColorEdge CG2420 reproduces almost the entire Adobe RGB colour space so images shot in Adobe RGB will be displayed correctly. Photos of vibrant blue skies and lush green forests are reproduced faithfully in a way that monitors limited to an sRGB colour space cannot display. The wide colour gamut also ensures reproduction of almost the entire ISO-coated and US web-coated CMYK colour spaces used in printing.
10-bit Simultaneous Display
Using the DisplayPort or HDMI inputs, the ColorEdge CG2420 offers 10-bit simultaneous display* from a 16-bit look-up-table (LUT) which means it can show more than one billion colours simultaneously. This is 64 times more colours than you get with 8-bit display, resulting in smooth colour gradations and reduced Delta-E between two adjacent colours.
Adjusted at the Factory for Smooth Colour Gradations
The gamma level for each ColorEdge monitor is adjusted at the factory by measuring the R, G, and B gamma values from 0 - 255, then using the monitor's 16-bit look-up-table (LUT) to select the most appropriate tones and achieve the desired value. This ensures the smoothest colour gradations in your images.
Stable Display Technology for Unrivaled ColorEdge Quality
The colour and brightness of an LCD monitor can shift due to changes in ambient temperature and the temperature of the monitor itself. ColorEdge monitors are equipped with a temperature sensor for accurately measuring the temperature inside the monitor, as well as estimating the temperature of the surrounding environment. With this temperature sensing and estimation technology, the monitor adjusts in real-time so gradations, colour, brightness, and other characteristics continue to be displayed accurately.
Start Working as soon as You Switch On
A typical monitor takes 30 minutes or more for its brightness, chromaticity, and tone characteristics to stabilize. The ColorEdge CG2420 takes a mere 3 minutes. Whether you are working in a studio or taking the monitor with you on location, you get reliable colour display soon after turning the monitor on.
Uniformity Across the Screen
Fluctuations in brightness and chromaticity on different parts of the screen are a common trait of LCD monitors. To counteract this, ColorEdge monitors are equipped with EIZO's patented digital uniformity equalizer (DUE) technology to ensure stable image display and counterbalance the influences that a fluctuating temperature may have on colour temperature and brightness for stable image display.
Wide Viewing Angles with IPS Panel
The 178° wide viewing angles afforded by the IPS panel technology allow two or more people to view the screen at once with little change in colour or contrast.
True Black Display
In compliance with the DCI standard, the ColorEdge CG2420 offers a high contrast ratio of 1500:1* for producing true blacks that are otherwise difficult to display on a typical LCD monitor. When viewing the screen from an angle in a dimly lit room, dark tones typically appear washed out due to the display characteristics of LCD backlights. The CG Series is equipped with a retardation film which allows tones to retain their depth even when viewed from an angle.
Easy-Access USB Ports
The monitor is equipped with three easy-to-access USB 3.0 ports, including one port for battery charging devices such as a smartphone.
DisplayPort, HDMI, and DVI-D inputs are included and support various types of graphics boards. The HDMI input also offers direct connection with digital cameras.
Minimized Reflections with Non-Glare Panel
The monitor is equipped with an IPS non-glare panel for high visibility. It
also uses dimming technology to minimize flicker and help prevent eye fatigue for a more comfortable working environment.
I/P Conversion for Flicker-Free Display
The HDMI input of the ColorEdge CG2420 supports I/P (interlace/progressive) conversion for converting the interlace signals from TV and video into progressive signals for flicker-free display.
The CG Series comes bundled with a shading hood that effectively prevents glare on the monitor's screen caused by ambient lighting. The ColorEdge CG2420's shading hood is newly designed and attaches to the monitor magnetically. This allows the users to attach the hood quickly and easily without needing to connect separate parts.
The slim cabinet features unobtrusive frames that are 39% slimmer than its predecessor.
Seamless Electrostatic Switches
The flat design uses electrostatic switches on the front bezel in place of traditional buttons for seamless access to monitor settings.
Built-in Carrying Handle
A carrying handle on the back of the monitor allows you to easily move it from one location to another.
Ergonomic Stand for Comfort and Convenience
Adjust the screen to the most comfortable angle and reposition it to show your work to a colleague or client. The monitor comes with a versatile stand that offers height, tilt, and swivel adjustments as well as portrait display.

Direct Hardware Calibration?
In Built Sensor?
Adobe RGB: 99%
This monitor supports Direct Hardware Calibration. It includes a built-in full calibration sensor.
This is the ideal way to calibrate a monitor - it's easy, fully automatic, and can be scheduled to occur even when you're not present and your computer is switched off! Simply set it up once and enjoy accurate colour with no further intervention for years to come!
An external calibrator is not required. However, if you wish to, you can cross correlate with an external calibrator. We list recommended models here. You would only do this under special circumstances.
We recommend the ColorChecker Display Pro / Plus (AKA i1Display Pro / Pro Plus).ColorChecker Display Plus (AKA i1 Display Pro Plus)
These calibrators are either simply not compatible, or do not measure current monitor technologies reliably. If you have one of these, it's time for an upgrade!i1 Display V1 & V2
Please note: Specifications are provided as a guide only.
We try very hard to keep these up to date and correct, but if a particular specification is really critical to you, then please double check the specification directly with the manufacturer. Some features may of course have caveats not fully described here.
To get more information about a particular specification, use the arrow to get a 'Specxplanation'.
Monitor panel sizes are measured across the diagonal, in inches.
They are approximate only, so the actual measurement might be 27.1" for example. Note that panel size in inches is only one part of the story - the other being the aspect ratio. For example a 24" monitors doesn't sound much bigger than a 23" monitor, but 24" monitors are normally 16:10 versus most 23" monitors being 16:9. This means a 24" monitor is much taller than a 23" and the working size is much greater than one inch difference would suggest.
The panel ratio gives the relative size of the horizontal to the vertical. Older monitors were 4:3, but most modern monitors are widescreen, with 16:10 or 16:9 being the common ratios. 16:10 is distinctly taller, and common with 24 and 30 inch monitors. 23 and 27 inch monitors are normally 16:9 - the same ratio as widescreen televisions. For monitors 24 inches and below, we recommend going with a 16:10 monitor if you can. Once you're over 24 inches you've got sufficient vertical working space it doesn't matter so much.
Native resolution is simply the number of pixels a monitor has, stated as horizontal x vertical.
LCD monitors really want to receive their native resolution and look pretty terrible when scaling other resolutions to the native resolution of the panel.
Most modern computers have no trouble outputting up to 2560 by 1600 (e.g. all Mac Pros/Macbooks/Minis/Airs etc. from the last 5 years or so can do this without issue, usually to 2 or more displays simultaneously). The only time it becomes particularly important is with older machines, particularly laptops, many have a maximum external display resolution of 1920 by 1200. If in doubt send us the full model number of your laptop and we can double check this for you!
There are three major types of monitor panels. IPS (aka PLS) - are the best for image makers. They have the best colour accuracy and uniformity characteristics. The can sometimes have weaker blacks, so gamers and video editors sometimes lean towards PVA monitors. However these days good IPS panels have excellent blacks so we recommend that all image makers use an IPS panel. The latest panel type, TN, is generally only used in laptops and low end devices and should avoided for imaging work at all costs!
The two major types of backlighting are CCFL (Flourescent tube based) and LED. CCFL is the older type of light source and offers good uniformity and it has been traditionally easier to engineer colour accuate monitors with flourescent tubes. However recent LED backlit monitors can be excellent - very uniform, and of course they use much less power. The latest LED backlit monitors from the good makers now offer excellent colour accuracy - at least as good as the older CCFL models.
LEDs also uses significantly less power (although CCFL monitors are already much better than old CRTs of course!) - and tend to have better uniformity.
Whether or not the unit needs a fan for cooling. Most monitors fortunately don't need a fan, rather using passive cooling through heatsinks and vents.
However, some monitors do require a fan, which can be of concern given the monitor's proximity to your ears. Generally the fan will be a low dB fan not audible above a typical computer fan, but if ambient noise is of concern to you the we suggest you choose a monitor without a cooling fan.
Calibration is the process of calibrating directly into the monitor's hardware. This is both more accurate, and typically more easy to do, than traditional software calibration. See the 'Calibration Information' section above for more details about this monitor and calibration.
In built correction sensors come in two forms:
Until around 2010, almost all monitors were 'standard gamut' - meaning they could display a moderate range of colours (roughly around the size of the sRGB colour space). In recent years we've seen the development of wide gamut monitors that can display a much wider range of saturated colours (about 25% more) - equivalent to approximately the gamut of AdobeRGB.
We recommend wide gamut monitors for all image makers, but especially for anyone working regularly with saturated colour. Wide gamut monitors can also emulate standard gamut monitors very well, so it's more future proof to choose a wide gamut model, and there really aren't any disadvantages (apart from the generally higher price of wide gamut models!).
Does the monitor accept a 10 bit incoming video signal? 10 bit video signals allow for more tonal level separation (i.e. smoother gradients).
PC: 10 bit is well supported and relatively easy to achieve with 'workstation' graphic cards (short version: buy an NVIDIA Quadro video card!). Since about 2020, even most modern consumer video cards now support 10 bit, but the consumer cards with their gaming optimised drivers do tend to be a lot more buggy.
Mac: 10 bit has been supported across the Mac lines since around 2016.
Note that there are often caveats to this support - such as 10 bit being available only on DisplayPort and not HDMI for UHD inputs, for example.
Do make sure you check the manufacturer's specifications very carefully if you have a particular requirement - like e.g. 10 bit over HDMI at 4K/60Hz.
Our comprehensive article on 10 bit support has more details. Important to note, also, that whilst 10 bit is definitely 'better' - in 20 years of professional imaging work, we have never really seen it make a practical difference to typical tasks (with the possible exception of HDR grading work).
The maximum achievable ratio of the brightness of a monitor's white to the depth of it's black. The stated figure is a maximum, achieved only when the monitor is running at high brightness in a darkened room.
A high contrast ratio makes things looks more contrasty (i.e. more 'pop') and is particularly of note with gaming, video, and image display scenarios. For example, if you're selling photos to clients straight off your screen, then high contrast has more wow factor.
However, for print work, it is typical practice to dramatically reduce the monitors contrast to as low as, say, 200:1 to better simulate paper. This is best done with monitors that feature direct hardware calibration support and allow you to specify the desired contrast ratio.
The maximum achievable brightness of the monitor in candellas per metre squared.
It is VERY unusual to run a monitor at maximum brightness, especially for imaging work.
The DCI (Digital Cinema Initiative) specifications requires contrast of 1500:1 or more.
Most LCD monitors do not yet offer DCI True Blacks support (in practice 'true blacks' means a very low black point suitable for video editing in a dim environment). This doesn't mean they have bad blacks in typical viewing environments, but it does mean you may experience some 'glow' in your blacks if you're viewing in a very dim environment.
Achieving very high contrast ratios is difficult and a combination of technologies is used - changes to the panel, light retardation film and backlight are all required.
This is really only of relevance in video work - in still image work, and particualrly for print, it is common practise to actually raise the monitor's black point above the minimum to better simulate the printed output.
The wider the better! But as usual, on paper specifications tell you just about nothing about the actual performance.
Viewing angle is the maximum angle at which a display can be viewed with 'acceptable visual performance'. In the context of this specification, all that means is that the 'contrast ratio remains above 10:1' (which is laughably low). This is really a meaningless specification with regards to the colour accuracy of a monitor when viewed off angle.
Thus, we don't place any credence in the manufacturer stated numbers. Simply though, IPS panels have the best viewing angles by far, and all IPS panels sold here all have (relative to low quality monitors) excellent viewing angles for this type of monitor, so you won't see significant variance as you move you head around under normal circumstances (movements of 15 or so degrees, say). In general you and a colleague could sit side by side (closely) and work acceptably together on an image. Beyond that, though, like all LCD monitors, accurate display will drop off very quickly once you move off angle. That is simply a fact of life with LCDs, even the best ones.
Ironically, monitors with lower black points tend to be slightly worse in this area (e.g. the CGX range from Eizo) - as often part of achieving the low blacks is the use of a polarising film over the panel. As anyone who has ever used a polarising filter with a camera knows, the effect of such a filter is highly directional. Thus as you move off axis, you will therefore see change more quickly.
How quickly a pixel can change colour, in milliseconds (usually measured as grey-to-grey, but there's no real standard).
Basically, any value 16 or under is generally fine for all normal uses. Exceptions are high end gaming and possibly video production - but it's rare anything below 10 makes a significant difference, and monitors with very low response times typically sacrifice a lot of colour quality to achieve this.
Can the monitor play back a 24p video signal (i.e. 24 frames a second) - without visible motion artefacts?
Typical desktop monitors either refuse a 24p signal altogether, or force all inputs to 60hz, remapping different frame rates like 24p to 60 frames per second (usually using a technique known as 3:2 pull-down). Unfortunately, because 60 is not evenly divisible by 24, this causes significant visible motion artefacts.
A monitor with 24p support is able to play back 24p sources at either the native 24 frames a second, or using simple frame doubling/tripling to play back these sources as 48 or 72Hz. This results in smooth motion without new artefacts (n.b. - artefacts inherent to 24p, like some juddering during slow pans, remains of course, as this is inherent in the low frame rate of the original filming - but it's this low frame rate that gives the 'film like' look.
More about 24p on Wikipedia.
The bit depth of the colour Look Up Tables. These are used to map incoming values from your computer to actual colours on the monitor's screen - so are of course crucial to colour accuracy. 8 bit is standard (although some appalling screens are only 6 bit!), but 10 bit or more is desirable, and the best monitors are now 14 or 16 bit. Ideally combined with 3D LUTs that can transform colours in more than one table at once.
Put simply the higher the bit depth of the LUT, the greater the capacity for accuracy.
3D Look Up Tables allow colour transformations to occur on R,G and B simultaneously, which increases speed and accuracy. Basically, a 3D LUT means better, more accurate calibrations. You want one even if it sounds like gibberish!
LCD Monitors coming off a production line typically exhibit some uniformity issues. Uniformity corrected monitors are broken into zones, measured, and each zone calibrated to be even with its neighbours (and you often get a written report of this process with very high end monitors like the Eizo CG series). Called DUE by Eizo, and most likely something else by others, it's an important part of the process of high end LCD making.
The process occurs at the begining of the monitor's life and there is currently no user system for correcting uniformity after the monitor is out in the field, although it is theoretically possible. Fortunately, moden monitors that leave the factory in a very uniform state tend to then remain uniform for many years of use.
Monitors that are not uniformity corrected may exhibit some visible artefacts like a change in density or colour across the field of the monitor. Wtih brands like Eizo and NEC, the non uniformity tends to be minor.
The input ports a monitor has. We have a comprehensive article about these (with pictures!) - here.
We've listed them here in our generally recommended order - that is, we recommend USB-C / DisplayPort / HDMI / Other...in that order, if the computer and monitor have the appropriate options.
Note that for USB-C ports that offer power delivery back to your laptop, we just list an approximate figure here - normally the monitor description text above has more details (e.g. this specification might say approximately 60W, when in fact it is 50W or 70W, say).
Other connections the monitor offers - such as card readers, audio connectors (for audio going in and/or out) - and USB ports.
Up here indicates an upstream port - meaning when you run a connection from your computer to the monitor.
Down indicates a downstream port - meaning you can plug something into this port (like e.g. a mouse, or a USB card reader).
Note, USB-C ports can be both upstream and downstream, and are thus often listed both ways, although there may be just one physical port.
A good way of double checking the ports on offer is to cycle through the product images above - we try and make sure each monitor listing has a picture of the available ports as well as the information here.
Some USB ports/hubs also act as proper 'KVMs' - meaning you can plug your mouse and keyboard into the monitor, then the monitor into two separate computers and easily share your peripherals and screen between the two machines. If proper 'KVM' support is something you need, review the manufacturer specs (linked below) to be sure this monitor can support your intended use case.
If a monitor hood is not included, then there are [LINK] aftermarket hoods available.
Monitor hoods stop direct light falling on the monitor which can make, in particular, shadow details harder to perceive. While not essential, once you get used to having one it's hard to go back to a screen without one - they improve the picture generally and provide a real 'window in to your image' effect.
Most colour accurate monitors don't have in built speakers.
Those that do offer speakers usually connect via 3.5mm jack (see connections), and the speaker output is usually around the 1-2w range. Fine for basic system sounds but not great for music etc.
Can the monitor be rotated on its stand 90 degrees and used in portrait orientation? Particularly useful if you're doing portrait work on smaller screens!
If the monitor & stand support this then you just rotate the screen physically and instruct your video card to flip the image 90 degrees (if you bind this to an F key on your keyboard it can be a very simple process!).
