An integrated calibration sensor governs the maximum color accuracy. It positions itself automatically for calibration and then conceals itself in the safety of the casing until the next measurement is taken. Each monitor is exactly coordinated using its sensor. For example, the measurement location is correlated with the middle of the image at the upper edge of the image so that the sensor takes measurements as if it were in the middle of the image. This integrated solution rules out the variability, which may arise when using external measuring devices. Even the influences of ambient light are determined when initiating the sensor and considered during calibration.
Devices with an integrated calibration sensor are able to perform calibration without the help of the user. The computer does not even need to be switched on. When programmed once, the calibration will start at night, during the lunch break, or at other, definable times. It is easy to program using the ColorNavigator or the on-screen menu.
Typical 1D look-up tables (LUTs) have separate tables for red, green and blue. Depending on the model, EIZO links the color allocation to a single, three-dimensional look-up table (3D LUT) to ensure particularly accurate color control and in doing so, allows for the exact addition of primary colors to any chosen color tone – vital technology for the ideal gray scale and ultra-precise color rendering.
EIZO has developed the RadiCS software specifically for quality assurance for image display devices in the RadiForce range. It offers extensive tests and automatic alignment to guarantee constant and consistent image reproduction on all RadiForce LCD monitors, but also supports screens from other manufacturers. The software automatically executes test images and helps to perform measurements and assessments in accordance with the guidelines in a cost-effective and time-effective manner. For example, measurement results are automatically transferred to the documentation and archived and can be centrally managed using the optional RadiNET Pro software. A calendar with a reminder function ensures timely checks are performed. A suitable measurement device is required to measure the luminance, including veiling luminance. Measured values from various luminance meters are automatically read by RadiCS.
According to the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU), the quality assurance guidelines are according to the X-ray ordinance (QS-RL): "Quality assurance measures for X-ray devices to examine or treat humans".

When you enable High Dynamic Range (HDR) in OS Display settings to use with ColorEdge selected SDR color mode, the color appears washed out.
When you disable High Dynamic Range (HDR) in OS Display settings to use with ColorEdge selected HDR color mode, the color appears extremely overexposed / bright.
Please set High Dynamic Range in OS Display settings correctly according to the selected color mode of the monitor.
Please refer to the user's manual for the SDR color mode and HDR color mode for each models.

Settings -> System -> Display -> HDR -> "Use HDR" turn off
macOS: Apple -> System Preferences -> Displays -> Display settings -> "High Dynamic Range" turn off
Yes, this is possible with an open and closed notebook through the monitor's power delivery function. To do this, deactivate the USB-C power supply of the notebook in idle mode in the Admininstrator menu of the monitor.
Compatibility Mode ON = Power supply active in idle mode
Compatiblitly Mode OFF = Power supply only when switched on
To start the notebook with the monitor switched on, please activate the function "Power On with AC attach" in its BIOS/UEFI.
Depending on the computer, the function name may be slightly different.
The EIZO ColorNavigator software can be used to calibrate and profile ColorEdge-LCD monitor hardware. IMPORTANT: Please do not use an alternative calibration software, which may not be able to use the hardware function of ColorEdge LCD monitors.
To keep your monitor looking like new at all times and to prolong the service life of your device, we recommend cleaning it regularly. Clean the casing and LCD surface as described below:
IMPORTANT: Never use thinner, benzene, alcohol (ethanol, methanol or isopropyl alcohol), scouring agents or other strong solvents as these may damage the casing and the LCD display.
Remove marks by wiping the casing with a soft cloth, which you have previously moistened with a mild cleaning agent. Never spray wax or cleaning agents directly on to the casing. (The manual contains exact details.)
Where necessary, the monitor surface may be cleaned using a soft cloth (for example a cotton cloth or glasses cloth). Stubborn marks can generally be removed by wetting the cloth with a bit of water to increase the cleaning strength.
EIZO offers different versions of the ColorNavigator software. They are compatible with Windows or Mac operating systems.
During the calibration by the user, the desired white point and gamma curve are transferred to the gray scale through a combination of measurements and calculations. This process is typical at EIZO as it saves time and is more precise than the measurements of several tone values with conventional manual measuring devices, which are prone to errors. The accuracy of the factory calibration with sensitive laboratory measuring equipment serves as a secure foundation in this regard.
Homogeneous luminance distribution and good color purity are key to achieving very accurate image rendering. The Digital Uniformity Equalizer (DUE) circuit takes care of this. It automatically corrects non-uniformities in terms of luminance and chrominance for all tone values across the entire image area – pixel by pixel.
When it comes to color accuracy when working, how well a monitor can differentiate between color tones is of fundamental importance. To achieve the maximum color depth and prevent the formation of stripes, banding, and washing, EIZO relies on the ultimate perfection: a 16 bit look-up table (LUT) ensures precise color resolution, meaning that even the finest structures in darker areas of the image are reproduced so that they are absolutely accurate in every detail.
In connection with a frame rate control (FRC) of the LCD modules, CG monitors allow for 10 bit color resolution, depending on the module. Screens can therefore display even the finest tone value gradations using a billion colors. This requires corresponding 10 bit support by the application software and graphics card.
The warranty for EIZO RadiForce monitors is 5 years for most models including an on-site replacement service. EIZO recommends an image brightness that is considerably higher than the minimum requirements in accordance with QS RL for monitors used for medical diagnostics. This recommended brightness is guaranteed by EIZO.
The corresponding product data sheets show which guarantee applies to which RadiForce model.
The color rendition of LCD modules varies with temperature and can, for example, be more than 5 ΔE in summer at 30° Celsius and above. Even an LCD module that has just been switched on deviates by up to 5 ΔE until it warms up. Color drift correction, in conjunction with a thermometer in the screen, counteracts this and ensures reliable color reproduction.
Both the installation wizard in RadiCS 5 and the corresponding functionality in RadiNET Pro enable an upgrade including data migration.
An important prerequisite for this is that the installed RadiCS 4 Version must be Version 4.6.1 or higher. For that reason, you should carry out an update beforehand for older RadiCS 4 installations.
The integrated KVM switch allows you to connect up to three computers simultaneously to the monitor. You can use it to switch between devices that are currently plugged into the USB ports on your monitor (for example, a keyboard or mouse).
To do so, please proceed as follows:
- Connect a computer via the USB-C port (labelled as video input) on the back of the monitor.
- Connect the second (and third, if applicable) computer to an HDMI input or DisplayPort and to the USB-B port on the back of the monitor.
- Peripherals such as a mouse or keyboard can be connected via the USB downstream ports located on the side of the monitor.
When the KVM functionality is enabled, the monitor automatically switches the controls to the active video input. Peripherals are connected to the USB-C device via a USB-C cable. Peripherals are connected to the HDMI/DisplayPort devices via the USB-B port.
Monitors and computers use a handshake to separately negotiate the power supply. The power supply is therefore protected against overloads and can be connected by the user without having to do anything but plug in the cable. We recommend using the USB-C cable supplied with the monitor since it supports 5A charging currents.
EIZO monitors support DisplayPort Alternate Mode with their USB-C interface. This means they can correctly display image signals from Thunderbolt 3 or Thunderbolt 4 ports via USB-C connection. The USB-C signal cable supplied by EIZO with the monitor has the optimal suitability.
Alternatively, monitors with a DisplayPort socket can be connected using a suitable cable. The CP200 signal cable (USB-C (TB3/TB4) to DisplayPort) provided by EIZO is the most suitable.
A connection from Thunderbolt 3 or Thunderbolt 4 ports to the HDMI interface of the monitor can work with suitable active adapters/cables. However, we recommend using the USB-C or DisplayPort interface of the monitor.
Yes, the USB LAN interface in EIZO monitors is usually suitable for use. For authentication during software deployment and system maintenance of client machines, we recommend using secure and unique GUID/UUID (Universally Unique Identifier) instead of MAC addresses.
Note: The use of MAC addresses can be incomplete because NICs such as USB LAN adapters, docks or monitors have their own MAC addresses and computers without a LAN port do not have a MAC address of the NIC. In addition, incompatibilities can - not infrequently - occur between hardware from different manufacturers. The use of GUID/UUID is manufacturer-independent.
GUID/UUID authentication for PXE-initiated deployments can be set quite easily in System Center Configuration Manager.
The following chat describes how it works:
Reusing the same NIC for multiple PXE initiated deployments in System Center Configuration Manager OSD - Microsoft Community Hub
Yes, the USB LAN interface in EIZO monitors is suitable for this. Each network adapter has its own MAC address, so computer authentication procedures are needed to replace the monitor's MAC address with the computer's address.
However, the procedures for the so-called MAC address pass-through are proprietary and lie within the sphere of influence of the PC manufacturers. Hardware from different manufacturers may be incompatible with each other. In this respect, the actual function must be checked or confirmed by the computer manufacturer.
If there is a lack of EIZO compatible support by the computer or its BIOS, the MAC address of the computer can be cloned into the EIZO monitor. For this purpose, we offer the free software "EIZO MAC Address Clone Utility" for Windows. This solution is manufacturer-independent.
As a rule, with the known methods, the MAC address transmitted to monitors is volatile after shutting down or removing the computer. This also applies to the "EIZO MAC Address Clone Utility".
Note: EIZO monitors with LAN interface support PXE. For PXE and authentication during software deployment and system maintenance of client machines, we recommend the use of secure and unique GUID/UUID (Universally Unique Identifier) instead of MAC addresses and their clones (see also FAQ on PXE).
Preparing for the move:
First make sure that RadiCS can be opened on the previous computer. Our recommendation: If necessary, update RadiCS on the previous computer to the same version that you will use on the new computer.
Carry out the move:
- Stop the RadiCS5Service under Services on the previous computer.
- Copy the db folder and the backup folder under C:\ProgramData\EIZO\RadiCS5 (hidden directory) to a suitable storage medium or network drive.
- Install the current RadiCS5 version on the new computer (if you are using RadiNET Pro, the RadiCSGatewaySettings.xml file must be in the RadiCS installation directory).
- Now stop the RadiCS5Service under Services.
- Rename the db and backup folder in the RadiCS5 directory on the new computer to _db and _Backup.
- Copy the db and backup folder of the previous computer from the storage medium to the RadiCS5 directory C:\ProgramData\EIZO\RadiCS5 of the new computer.
- Start the RadiCS5Service.
- Now open RadiCS5 and make sure that all data has been restored.
Often, people forget to establish the USB connection between the monitor and the PC/Mac. ColorNavigator uses the USB cable to calibrate the monitor. Please check that the USB cable is inserted correctly and is also functioning properly.
EcoView Automatic is turned on by briefly pressing a button. In the case of strong lighting, the image brightness is increased, while it is reduced in the case of weak lighting. This results in the highest levels of ergonomic comfort at the workstation thanks to the most constant contrast possible, which incidentally saves both money and the environment.
Most Web browsers do not support color management. This means that the browsers ignore images’ color profiles. As a result, sRGB images, for example, are displayed in the monitor’s entire gamut (wide gamut). This is why the images are displayed in an oversaturated way. This also applies for image viewing software that doesn’t support color management.
The sRGB mode that is included on all EIZO monitors offsets the monitor colors in the sRGB gamut. This allows the EIZO monitor to correctly display the sRGB images in the browser/viewer by getting the monitor to correct what the browser or image viewing software ignores.
The ColorNavigator software is used to simply and accurately calibrate ColorEdge screens.
EIZO RadiForce monitors that can be used in close proximity to the patient fulfill the requirements of EN60601-1 or the CE-Medical Device Directive. The product data sheet describes whether a RadiForce model provides this level of electrical safety.
EIZO RadiForce LCD monitors can generally be removed from their bases. They are equipped with four VESA-compatible drill holes to attach other holding devices on the reverse. Before they are fitted, the maximum load-bearing capacity of the mounting device should be checked.
4K UHD describes a resolution of 3840 x 2160, compared to a resolution of 4096 x 2160 for 4K-DCI.
4K DCI is commonly used in the film industry.
An incompatibility may occur with Apple M1/M2 devices due to a special feature of the picture signal. Under special circumstances, this can lead to flickering of the monitor image. A firmware update can limit the refresh rate to 30 Hz, which eliminates the flickering. However, the CS2400S-LE is fully compatible with all Windows PCs and Intel Macs.
CS2400S-LE have a clearly visible sticker on the box with the words "Limited Edition". The production date on the box and nameplate is May 2023 (or earlier).
CS2400S produced in June 2023 or later are not limited edition.
This is an incompatibility due to the picture signal between the screen and Apple M1/M2 computers. Please use the latest firmware update from our website to use a 30 Hz picture signal. This will prevent flickering from occurring. Flickering that has already occurred can also be remedied by switching off the monitor for about one hour.
No, you do not need a driver. The monitors are identified via the signaling line and then installed as a standard or plug & play monitor.
We cannot make a direct recommendation. The output signal should be digital and should support the maximum resolution of the monitor.
Digital signal encryption system as copy protection for digital contents, for example for videos, music, etc. The transmission of digital contents is protected as the contents are encrypted on the transmitter's side, sent via a DVI output and once again decrypted on the recipient's side. Digital contents may not be reproduced if both the transmitter and recipient device do not support HDCP.
It measures the ambient light and automatically adjusts the brightness of the monitor to ensure that the contrast is as stable as possible. The image brightness is increased in a bright environment and it is reduced in the dark. It is also possible to control the brightness manually.
Wide gamut designates a color space that is considerably larger than the visible palette of conventional LCDs. Depending on the model, it covers up to 100% NTSC and 99% of the Adobe RGB color space. The colors of these monitors bring about a realistic image quality that was previously impossible in LCDs.
No special compatibility is required between EIZO monitors and Windows 11. If supported by the graphics card or chip and its driver, all monitors and their resolutions will be correctly recognised and applied.
EIZO software will support Windows 11 in the future as follows:

The EIZO on-site replacement service is performed by our service partner UNISERV GmbH. Please use the contact form: www.eizo.be/support-service/repair-service/. If you need to replace your device, an equivalent replacement device will be ready for you within one working day. A driver will come to you and deliver the replacement device to your incoming goods area or reception. He will take the defective device with him.
Screens have millions of pixels, which each have a surface area of less than a hundredth of a square millimeter. These elements may have defects, which are expressed by them being constantly lit or unlit. Visibility is fundamentally dependent on the surrounding area. For example, lit elements are almost invisible in a bright environment. Each LCD screen is unique in terms of pixel errors.
To give you a clear statement about what frequency of pixel errors EIZO deems tolerable, EIZO screen models are tested according to internationally recognized standards. On average the actual levels are in fact far below the tolerances across all of the devices. LCD modules that do not meet these requirements are not used at EIZO. Depending on the model, EIZO monitors have a zero pixel error guarantee for completely illuminated sub-pixels (partial pixels ISO 9241-307). Valid: six months from the purchase date.

Since the German Electrical and Electronic Equipment Act (ElektroG) entered into force on March 24, 2006, old electrical equipment can no longer be disposed of with the normal waste. It must be disposed of in an environmentally friendly manner and recycled. This also applies to old EIZO devices.
If you are a private end consumer, you should simply take your old monitor to a local collection center. You will not be charged for this. You can find out where your nearest collection center is from your local authority.
If you are a business customer, simply contact us.
If necessary, first update your computer to a current BIOS version, then check the UEFI/BIOS settings with regards to the DisplayPort settings. Some PC manufacturers already offer a solution. Only if these steps do not provide a remedy could a firmware update of your monitor help. In all other cases, a firmware update of the monitor is unnecessary.

EIZO monitors generally have two or more signal inputs. You can easily switch between two or more computers by pressing a button on the front of the monitor. For devices with KVM switch functionality, the USB hub also switches to the respective computer at the same time.
At resolutions greater than 1920 x 1200, you need a DualLink signal and cable, as the bandwidth is higher than 165 MHz.
This may be a problem with the graphics card driver. Please install the latest driver for your graphics card and restart the PC with the monitor.
Older graphics cards may not be able to display this resolution. In this case, you will require a new graphics card with the matching output.
Spectrophotometers and colorimeters are able to measure light colors. They can be used equally well when combined with the EIZO ColorNavigator monitor calibration software. Spectrophotometers can also measure body colors. Further software from the measurement device manufacturer is necessary, however, to calibrate scanners, printers, and other output devices.
Firstly, please check the resolution of the LCD screen. Check the recommended resolution stated for the respective LCD screen. If you have set a lower resolution than recommended, this may result in blurring.
The LCD display is comprised of a fixed number of image elements (pixels), which light up to display the contents of the screen. The image is comprised of horizontal and vertical pixels. LCDs achieve the best image quality if all pixels can be allocated data, i.e. if the resolution configured on the computer corresponds to that of the LCD display.
The color temperature is a benchmark for measuring the white tone and is stated in Kelvin. At high temperatures, the white tone appears slightly blue, while it has a more red tone at low temperatures.
5000 K: Often used in the printing industry.
6500 K: Suitable for displaying photos and video images.
The color tone rendering is relative to the change of the input signal level. This relationship is generally known as the gamma characteristic. In image reproduction, low gamma values result in white images and high gamma values result in high-contrast images.
International standard for an RGB color space. A color space has been defined, which most devices can comply with, to enable color matching between various applications and devices, such as monitors, scanners, and digital cameras. sRGB images, which are detected or issued on "sRBG devices" are limited to the full sRBG color range and no colors outside the sRBG color space. Color allocation, white point, and gamma are permanently defined.
In connection with a USB-compatible computer, the monitor acts as a hub, to which other USB-compatible peripherals can be connected.
The viewing angle relates to the angle, beneath which the contrast is better than 10:1. These are normally values of 160° to 178°. These values do not provide any information about what enormous differences in contrast may result within the viewing angle. The contrasts should not change significantly for users with a perpendicular view and a slightly side-on view. It must not make a difference whether the viewer is looking at the middle of the image or the edge of the image. How much the contrast stability varies with different LCD technologies is best checked using a measurement diagram or by a direct visual comparison. The more stable the contrast in the user's viewing frustum, the better the image rendering.
High Definition Multimedia Interface. Interface to transfer digital audio and video data
Full High Definition. High-definition image display with 1920 pixels in 1080 lines. Full HD is either transmitted in 1080p (progressive) or 1080i (interlaced).
Pixels are precalculated using this function and purposefully accelerated by intelligent steering. In this way not only the black-white changes, but even changes of color nuances are shown very rapidly. Image changes in fast video sequences, 3D CAD animations and games therefore do not suffer from unwanted ghosting effects.
This is where the signal values are allocated to the color tone values for the output in the monitor. EIZO monitors are 24, 16, 14, or 10 bit instead of the conventional 8 bit look-up table (LUT) for precise color control. Precision work, performed by a high-performance chip developed in-house at EIZO.
Balanced brightness is crucial for brilliant color reproduction. Traditional LCD monitors need one to two hours to even out their brightness. However, even then, they are still sensitive to temperature deviations. Patented electronics regulate the backlight, depending on the model. They ensure constant brightness, regardless of the operating times and temperature.
EcoView Index appears on the screen at the press of a button. It shows how ecological the screen's current settings are. This makes it visible how energy-efficient and cost-effective the current brightness is.
Backlights with white LEDs have the same brightness as CCFL backlights yet consume half as much energy. That means extremely high energy efficiency and rapidly falling electricity costs. An added benefit: In contrast to fluorescent tubes, LEDs do not contain any toxic mercury, which is harmful to the environment.
This is a digital signal interface for images and sound signals for computer monitors with a high transmission bandwidth and a compact plug design.
Where saving energy counts, the EcoView Sense function really comes into its own. It automatically turns the screen on or off, depending on whether the user is sitting/standing in front of the screen at that time. EcoView Sense will notice that the user has returned even before the mouse is moved or the keyboard is touched. The screen is therefore always ready for use immediately and does not waste any energy when the user is not in front of it.
Contrast is the ratio of white to black and for monitors is normally stated as a dark room contrast from a controlled laboratory environment. Typical contrasts on printed paper are 6:1 for newspapers, 31:1 for laser printers, 49:1 for photo paper. For example, dark room contrasts cannot be achieved in the office because an extremely deep black cannot be achieved in normal ambient light – even with the screen turned off.
Smart Insight determines the content of dark scenes and optimizes them such that they are more visible and clearer.
A signal input with DisplayPort signal version 1.2 (or higher) or HDMI with 4K and 60 Hz is required to be able to operate 4K resolutions with 60 Hz.
MST transmits two halves of an image (right and left), each 2x2K at 30 or 60 Hz. This operating system looks at the halves of the image like separate screens as long as they are not connected to a screen by a driver or accessory software. This method is obsolete in modern 4K monitors because it can process the 4K image in full via display port 1.2. This method of transmission is called SST. In this case, the full image, i.e. the full 4K resolution, is transmitted to the monitor and displayed at 60 Hz.
No. In general, every good display port cable is capable of transmitting 4K at 60 Hz.
My 24" ColorEdge monitor is connected via HDMI, but the operating system only allows a resolution of 1920x1080 instead of 1920x1200. How do I get the full resolution?
EIZO monitors have a USB-C interface that supports what is known as DisplayPort Alternate Mode. This allows the monitors to receive image signals via a USB-C connection. The computer system and/or its USB-C port also has to support this mode, e.g., MacBook Pro and its Thunderbolt interface. Please note the computer manufacturer’s specifications.
