Eizo's CS2731 is the 27" entry point into professional colour accurate monitors from the best brand in the business.
Eizo's CS2731 is the new, USB-C enabled replacement to the very popular CS2730.
The CS range is Eizo's entry point into their professional level ColorEdge colour accurate monitor range. Whilst you don't have the in-built, automatic calibrator of the more advanced (and expensive!) CG models, you get a lot of the quality, for a lot less price.
In terms of the CS2730 which it replaces, this new model adds USB-C input & power delivery, but also notably improves the electronics, with improved 16 Bit 3D LUTs and Eizo's legendary and unequalled hand tuning processed meaning you get superb colour quality without the fill CG pricetag. You get Eizo's legendary control of deep shadow tones, and great uniformity and neutrality. These monitors are perfect for day to day professional imaging work and are backed by the best (5 year!) warranty & brand in the business.
The ColorEdge CS2731 unites precision, colour fidelity and cutting-edge connectivity. Convenient functionalities such as monitor signal transmission, rapid data transfer and the power supply feature for connected notebooks or tablets are enabled with just one USB-C cable. This makes the monitor the central dock for any graphic workflow. As an integral component of the digital creation process, the CS2731 supports creatives like photographers, film makers and designers. The wide gamut(99% Adobe RGB), 16-bit look-up-table and precise factory calibration of the hardware-compatible graphics monitor allows you to get an unadulterated look at your image files. The Digital Uniformity Equaliser ensures a uniform image display via the entire display surface and makes the CS2731 the ideal monitor for sophisticated creatives with high standards.
All Eizo ColourEdge monitors come backed by a manufacturer’s five-year warranty.
Excellent Image Quality for Sharp Images
The screen comes with a resolution of 2560 x 1440, an impressive contrast ratio of 1000:1 and a brightness of 350 cd/m2 so you are able to edit graphics and images with pixel accuracy. The LCD panel with IPS (Wide Gamut) technology enables a viewing angle of 178 degrees, ensuring that hues and contrast remain stable for the viewer.
Cutting-edge Connectivity Thanks to USB-C Connection
Convenient functionalities such as monitor signal transmission,rapid data transfer and the power supply feature up to 60 W for connected notebooks or tablets are enabled with just one USB-C cable. This makes the monitor the central dock for any graphic workflow. Periphery devices such as a mouse and keyboard,hard disks and card reading devices can be connected directly to the monitor’s USB hub. Portable computers can be connected using just one cable, which also allows them to be charged at the same time. This means that a laptop and CS2731 can be transformed into a fully equipped desktop workstation with just a few adjustments.
Wide Gamut – Ideal for RAW Images and Prints
Those working with RAW or Adobe RGB images should look no further than our wide gamut monitor: the wide colour space reproduces 99% of the Adobe RGB colour spaces. If pictures taken in RAW format are converted to Adobe RGB, the monitor will display them absolutely correctly. For example, you can see a shining blue sky or lush green forests that are true to nature– unlike monitors with sRGB colour space. The EIZO monitor also offers great benefits when printing: It covers almost the entire CMYK colour space (for example ISO Coated and U.S.Web Coated). You can already see on the screen how your subsequent print result will look, saving yourself proofs.
Exact and Fast hardware Calibration
Calibration becomes quick, easy, and colour accurate with the ColorNavigator software: Calibration is accessed and stored directly on the look-up table in the monitor’s hardware during calibration. You determine the corresponding components such as white point, gamma, brightness, and tone curve according to your needs. The calibration is then fully automatic and based on the factory adjustment and is therefore unique in terms of precision and speed.
High Resolution Look-up Table
Thanks to the 16-bit look-up-table, the CS2731 offers precise resolution of image signals. Colour nuances and image structure are not lost, particularly in the case of dark hues. This reliable and precise reproduction reduces calibration steps, saving valuable production time.
Professional Calibration with EIZO ColorNavigator
Good image editing can only take place with a well-calibrated monitor. The standard software calibration takes a long time and requires the user to have technical expertise. The CS2731 is delivered with the ColorNavigator hardware calibration software. It can be even be performed by users with no technical expertise in just a few steps. Advanced users can enter numbers for brightness, gamma, white point, and other calibration settings as target values. As the calibration uses the monitor’s hardware,it takes place without losses and independently of the computer and graphics card. The CS2731 integrates perfectly into an existing system.
Exact Colour Reproduction – Factory Calibration
With LCD panels, the image display can vary from module to module. That is why each ColorEdge monitor is precisely measured and calibrated in the factory. The gamma curves for the red,green and blue channels are tested according to strict parameters and corrected if necessary. This unique EIZO factory calibration enables the user to start using the monitor with the preset gamut right out of the box. In addition, the factory calibration allows the user to quickly recalibrate the monitor if needed using ColorNavigator.
EIZO Microchip for Optimised Colour Reproduction
The CS2731 has a high quality microchip (ASIC, Application Specific Integrated Circuit), which EIZO has developed specifically for the special requirements of colour-proof work. Thanks to their own algorithm, EIZO ASICs ensure a precise, uniform, and constant colour display.
Constant Tone Value Over the Entire Screen
Digital Uniformity Equaliser (DUE) controls all tone values over the entire monitor, pixel by pixel. The effect: colour tones appear identical at each point on the screen, without the brightness fluctuations you experience in conventional LCDs. The DUE function also balances out the effects of fluctuations in ambient temperature on the colour temperature and brightness. You will enjoy consistently even luminance distribution and perfect colour purity. A real plus when touching-up images.
10 bit Colour Depth: a Billion Colors in the Finest Grades
Thanks to the 10 bit colour display based on a 16 bit LUT, you can utilize a huge colour spectrum. This is made possible by the rapid Display Port and HDMI connections in combination with the frame rate control. A billion colors at your fingertips simultaneously. That is 64 times more colors than with an 8 bit display. The colour gradations are finer and the colour differences between adjacent colors are smaller. The enhanced greyscale range is equally important for post-production. With the 10 bit greyscale range activated, between 6% and 14% more grayscales are visible.
Lightning-fast Colour Mode Changes
You can access colour modes from the monitor’s memory at the click of a button. Standards such as AdobeRGB and sRGB are preconfigured at the factory. There are also settings that you can calibrate yourself. Switching between modes takes mere seconds, and does not involve any delays caused by renewed calibration.
The monitor is flicker-free at every brightness setting. The benefit: Your eyes do not get tired as quickly. You can work on the screen for an extended period.
One Monitor, Many Ports
It doesn’t get simpler than this: most end devices, such as PCs, laptops or cameras, can be connected directly to the monitor, thanks to its wide range of interfaces. The existing USB-C interface can be used for regular upstream data transfers as well as to transmit Display Port video signals and audio signals. This means a computer with a USB-C port can be easily connected with just the one cable. A USB-B interface is also available as another upstream port. On the USB down-stream side, the CS2731 has two USB Type B and two USB Type A ports.The CS2731 supports a wide range of video formats via a Dis-play Port, DVI-D and HDMI input. As a result, the monitor can be integrated into PC-based workflows and be used with HDMI feeds.
Quick Operation – Even In Dark Rooms
Operation is easy and clear. The Button Guide, an overview function on the monitor, will show you the respective function keys above the control panel. The backlight keys mean that the monitor can even be used in dark environments. This is particularly helpful in dark post-production studios.
Ergonomic and stable: the adjustable base
The CS2731 has a flexible base to adjust the height, tilt, and rotation and supports both portrait and landscape use. The monitor can be tailored to the user’s needs. For example, he can set a sitting position that is ergonomic for him (e.g. lowered to the bottom) or a position to show clients and colleagues something on the screen.
Perfect Anti-glare Coating
The IPS panel has optimal anti-glare coating. It diffuses the reflected light to minimise glare, protecting your eyes from strain. In addition, the monitor provides for a wide viewing angle without any distracting reflections. This is particularly advantageous when multiple people are seated in front of the same monitor.
Light-Shielding Hood – Available as add on
An optional shading hood is available that effectively prevents glare on the monitor's screen caused by ambient lighting. The hood is designed to “stick” to the monitor magnetically. This means you can attach the hood quickly and easily without needing to connect separate parts.

Direct Hardware Calibration?
In Built Sensor?
This monitor supports Direct Hardware Calibration and comes with a full version of ColorNavigator to achieve this.
However a calibration sensor is not included and needs to be purchased to take advantage of this system.
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!).
