If you want to step into the world of Eizo monitors, the ColorEdge CS2400S is a great place to start. This 24-inch monitor may be an entry-level model, but it is well worth considering. I was given a unit to review.

The ColorEdge CS2400S is Eizo's latest monitor with a 24-inch screen diagonal and a resolution of 1920 x 1200 pixels. The number of pixels in height is slightly higher than the standard Full HD format of 1080 pixels. This gives you a little more space for editing photos.

The Eizo ColorEdge CS2400S is a beautiful, cleanly designed monitor that offers a very pleasant viewing experience.

The specifications of the ColorEdge CS2400S are of course important. I have listed them for you.

The appearance of the ColorEdge CS2400S

A 24-inch monitor is in fact the ideal monitor size. It is not as huge as a 27-inch screen, but still large enough to work with comfortably. The extra 120 pixels in height, 1200 instead of 1080, make the image look less narrow.

The touch-sensitive buttons are illuminated. The duration of the illumination and the sound when touching them can be adjusted or switched off as desired.
The appearance is clean and typical of modern Eizo monitors. The screen bezels have the right thickness for graphics displays. You will find the touch-sensitive controls for the menu and, of course, the on and off button. Touching the buttons makes them light up, and when not in use they are unobtrusive and dark.

The round stand gives the 8.2-kilogram monitor a stable base. You can rotate the monitor effortlessly. The height and angle of the monitor can also be adjusted. This allows you to set it up perfectly for your workspace.

The monitor can be adjusted in height. This can be done with the stand, but also at the monitor connection. The total height adjustment is 155mm.
The stand has a cable clamp with enough space to hide all the necessary cables behind it. You do not need many cables, unless you make maximum use of the possibilities. There is an HDMI, a DisplayPort, a USB cable for the USB hub, and a USB-C connection.

There is a cable clamp at the rear of the stand, providing enough space for all the cables you can connect.
The USB hub is on the left-hand side. There are two USB2 and two USB3 ports available. If you use the USB-C connection to connect your computer, the USB cable for the hub is not needed.

An overview of the connections on the ColorEdge CS2400S. The main switch is located next to the mains cable connection, allowing the monitor to be properly switched off.
With the USB-C connection, you can use your monitor with a single cable, giving you a clean and tidy desk. If you use a laptop, the 70-watt power output can be used to charge it directly.

The menu

The ColorEdge CS2400S menu is operated with the six touch-sensitive buttons on the front. They light up when you use them, and a beep sounds when one is pressed. This sound can also be switched off in the menu.

An overview of several menu pages. The monitor offers many adjustment options.
One of the touch-sensitive buttons lets you select the input signal directly, while another switches between the different configured colour spaces. There are also two shortcut buttons that you can programme yourself. The function of the buttons changes depending on the menu. The labels below the menu clearly show what each button does.

The display

The monitor offers four colour spaces. sRGB has 100% colour coverage, while AdobeRGB and CMYK ISO Coated V2 both have more than 99% colour coverage. DCI P3 covers 95% of the colours.

All settings can be adjusted manually, right down to individual colours. Seven different custom presets can be programmed. You can change these at the press of a button without having to go deep into the menu.

An internal Look-Up Table (LUT) is available, with a colour depth of no less than 16-bit. This cannot be selected or adjusted manually. The monitor uses this LUT to generate the 10-bit colour display that the monitor can show. This continuously optimises the colour display.

Download ColorNavigator from the Eizo website to calibrate and set up the monitor. This is not required, however, as the monitor comes with hardware calibration.
The monitor's brightness is matched to the selected colour space. You can adjust this manually up to a maximum of 450 cd/m2. The monitor's contrast is 1350:1.

The screen brightness is linked to the different colour profiles. But you can increase the brightness to 450 cd/m2. Above 370 cd/m2, the value is displayed in magenta.
Thanks to the wide 178-degree viewing angle, you do not need to sit exactly in front of your monitor for the best colour display. You can assume that virtually any viewing angle guarantees perfect contrast and colour reproduction.

The display has a matte finish that reduces reflections as much as possible. That does not mean that light sources cannot be reflected in it, but it is not a mirror in which you can see yourself. This makes it less distracting when there is a light source behind you, or when you are sitting in the light yourself.

The monitor's viewing angle is very wide. Colour reproduction and brightness remain excellent, even from these extreme angles.

Connections

The USB-C connection with 70 watts of power offers many possibilities for laptop users. With a single cable, your laptop can drive the display and receive data through the USB ports on the screen. This allows you to connect a mouse and keyboard to the monitor instead of to the laptop or a separate hub.

If you have a laptop and a desktop computer, you can connect both. The KVM switch recognises which input is active. If you have everything connected to the hub, you can use a single keyboard and mouse for both computers.

The screen does not reflect at all. If you have a bright light source shining on your display, this will be visible as a bright spot, as in this example. This is the light from an on-camera report flash firing directly into the monitor.
It is not compulsory to use USB-C for your video signal, by the way. The monitor also has DisplayPort and HDMI. Unfortunately, there is no USB-C connection on the monitor's hub. If you have external peripherals that use USB-C, you can only connect them via an adapter.

Conclusion

The Eizo ColorEdge CS2400S is a superb monitor with a large number of features that will certainly appeal to photographers and graphic designers. In terms of settings, the monitor is not as extensive as Eizo's more expensive and professional monitor range. But it is more than enough to make it a very capable monitor.

Some menu options are not immediately clear if you are not an expert, and unfortunately there is no good documentation. You therefore have to investigate for yourself to find out what these settings do. Think of settings such as Gamut Clipping and Picture Expansion. Fortunately, the latter can be set to automatic.

The monitor can also rotate as well as being adjustable in height. You can also put the monitor in pivot mode.
These connections make it possible to connect a computer or laptop very easily. The power supplied via USB-C is a respectable 70 watts. This may not be enough for more high-end laptops.

The screen is comfortable to look at, without distracting reflections. Thanks to the combination of resolution and screen size, text is perfectly legible. The extra pixels above the Full HD height may seem negligible, but they provide a little more room for displaying photos.

Like all modern Eizo monitors, the ColorEdge CS2400S has a handy grip.
I cannot say much about the colours and uniformity across the display. I do not have a colour meter or other measuring equipment to check the values specified by the manufacturer.

What I can say is that the display looks perfect to the eye. Brightness gradients blend smoothly into one another, without any banding. There is no difference in brightness towards the edges, which indicates that the Digital Uniformity Equalizer is doing its job well.

Pros

• Resolution of 1920 x 1200 pixels provides much more space in height
  
• Fantastic, calm and pleasantly flicker-free image
  
• The Eizo Digital Uniformity Equalizer ensures even brightness across the entire surface
  
• No reflective image
  
• Wide viewing angle
  
• Pleasant and clear menu, although some options are at expert level
  
• Easy switching between colour spaces and input signals
  
• Switching between two computers is possible via the KVM switch
  
• USB-C connection provides 70 watts for charging a laptop or other device
  
• ColorEdge calibration software available
  
• Monitor has hardware calibration for brightness, white point and gamma, among other things
  
• Light hood available as an accessory
  
• 5-year warranty and environmentally friendly packaging
  

Cons

• USB-C power delivery is 'only' 70 watts
  
• USB connections only on the dock, no USB-C
  
• Bezel thickness makes the monitor unsuitable for multi-monitor setups
  
• The purpose or reason for the Gamut Clipping and Picture Expansion options in the menu is not explained anywhere
  
• Light hood not included
  
• Despite its keen price, it may still be above the budget of a larger group of enthusiasts
  

If you are looking for a quality monitor, the Eizo ColorEdge CS2400S is a superb monitor that will give you many years of enjoyment. The hardware calibration guarantees accurate colour reproduction. Eizo also offers the option of carrying out an additional check over time using external Eizo software. This ensures that even after the 5-year warranty, you have a monitor you can rely on. I can certainly recommend the monitor.

The Eizo ColorEdge CS2400S is available for 812 euros. An LE version is also available. However, this limited version of the monitor has one disadvantage. It does not work with Apple computers with an M1 or M2 chip. This will be possible later with a firmware upgrade, but with a maximum refresh rate of 30 Hz.

This limited version is therefore only suitable for Windows users. The price of this LE version is 659 euros, which is much lower than the standard version.
