CG2420 ColorEdge

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.

All about monitor 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.

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.

Casing
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.)

LCD display
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.

Details about the supported operating systems can be found here.

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.

All about monitor calibration

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.

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.

The EIZO software does not run or runs slower on Windows 11 when Smart App Control is enabled. To solve the problem, please disable Smart App Control in Windows 11.

1. Enter "Smart App Control" in the search in the taskbar.
2. Select the Smart App Control system settings.
3. Change the setting to Off.

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.

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.

DisplayPort-HDMI conversion cables are designed for connecting a DisplayPort output at the graphic card and a HDMI input at the monitor. An HDMI output does not support DisplayPort signal. Therefore, such cables do not work the other way around. Please connect the monitor in another way, e.g. using DisplayPort output or USB-C output with DisplayPort Alt mode. We recommend the DisplayPort input at the monitor, since some computer and/or operating systems do apply special signal settings to a HDMI device, e.g. limited signal range or gamut settings.

DisplayPort-DVI conversion cables are designed for connecting a DisplayPort output at the graphic card and a DVI input at the monitor. An DVI output does not support DisplayPort signal. Therefore, such cables do not work the other way around. Please connect the monitor in another way, e.g. using DisplayPort output at the computer and DVI input at the monitor side. If you must use DVI output you may connect to HDMI input at the monitor with a DVI-HDMI conversion cable. For selecting the cable, please mind if your signal is dual link DVI or single link DVI.

Most adapters are DisplayPort to HDMI which means DisplayPort/Source/PC to HDMI/Sink/Monitor.
The DisplayPort output of your computer will detect an HDMI monitor and send an HDMI signal over its DisplayPort output. These cables only work in this direction. It does not work in the direction HDMI/Source/PC to DisplayPort/Sink/Monitor. HDMI outputs cannot send a DisplayPort signal. Please use a different adapter like USB-C to DisplayPort, HDMI to DVI or use a dedicated active HDMI to DisplayPort converter.

To achieve optimal results, it is advisable to familiarize yourself with the colour management topic.

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.

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:

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.

The letters behind the numbers have the following meanings:

• BK: Black casing
• GY: Gray casing
• WS: White/silver casing
• WT: White

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.

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.

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.

This is a digital signal interface for images and sound signals for computer monitors with a high transmission bandwidth and a compact plug design.

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.

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?
