Precision and color accuracy

High-contrast, bright and crisp screen

4K UHD resolution

Thanks to the resolution of 3840 x 2160 (4K UHD), the CS2740 has an enormous pixel density of 164 ppi. Visible monitor pixels are guaranteed to be a thing of the past and even the monitor display gives a very meaningful impression of the subsequent print resolution. The IPS panel has a maximum brightness of 350 cd/m² and achieves a contrast ratio of 1000:1. Films can be assessed, edited and graded with the CS2740 in full 4K UHD resolution. The LCD module allows a viewing angle of 178 degrees. This keeps colour tones and contrasts stable in the user's viewing cone.

For saturated colors

Wide gamut color space

To be able to use the entire colour spectrum of modern cameras, you need a monitor with the largest possible colour space. Only then is it possible to visually assess and edit the saturated hues contained in the file. That is why the IPS panel of the ColorEdge CS2740 covers, for example, the wide AdobeRGB photo gamut as well as the CMYK print gamut ISO-Coated V2 to more than 99 %. This means that the full colour spectrum of modern cameras is represented unaltered and without gaps. And a precise simulation of the print result in the softproof view is also guaranteed.

Precision-color_WideGamut_CS.jpg

Outstandingly sharp image quality

The monitor has an impressive top resolution (3840 x 2160 (4K UHD)), a very good contrast ratio of 1000:1 and a brightness of 350 cd/m². For example, you can edit graphics and images down to the pixel. As an added benefit, text contours are clear and precise. The LCD panel with the IPS (Wide Gamut) panel allows for a viewing angle of 178 degrees. Ensuring that hue and contrast remain stable for the viewer.

Precision-color_IPS-Panel_CE.jpg

Smooth and fluid transitions and gradients thanks to 16-bit LUT and 10-bit mode

The LUT (look-up-table) on the CS2740 employs internal calculations with 16 bits for an extremely high colour depth and outputs the signals with up to 10 bits. This provides billions of hues for calculating the precise monitor display, effectively preventing display errors caused by the monitor such as banding or clipping, which can result in tonal breaks in gradients or unnecessary colours in greyscale. Even fine nuances and structures in dark or highly saturated areas of the image can be displayed in a differentiated and detailed manner.

Ready to use right out of the box

Perfect settings right from the factory

Every ColorEdge CS2740 is individually measured and optimally configured in the factory, enabling it to be used immediately after it has been unboxed. To this end, the gamma curves for the red, green and blue channels are closely checked and corrected, if necessary. This unique EIZO factory calibration enables the user to start using the monitor with the preset gamut range right out of the box. This painstaking calibration at the factory ensures that the user can quickly recalibrate the monitor if needed using ColorNavigator.

Precision-color_Factory-calibration.jpg

Perfect rendering across the entire screen

Digital Uniformity Equalizer

Each individual monitor panel is precisely measured over the entire surface at the EIZO factory. Any inhomogeneities in brightness and unnecessary colour are detected and removed. This process (Digital Uniformity Equalizer) guarantees that identical colours always look the same over the entire service life of the monitor, no matter where they are displayed. Only in this way is precise image processing and retouching possible.

Fast, easy and lossless

Hardware calibration without any compromises

It is essential that the monitor is regularly calibrated to ensure that it always displays the same file in the same way over its entire service life. To do so, all ColorEdge monitors employ lossless hardware calibration. Unlike software calibration, which always involves the risk of loss of display quality, hardware calibration not only creates an adjustment profile for the graphics board but also calibrates the monitor’s LUT (look-up-table).

Precision-color_Calibration_CS.jpg

EIZO software for fast calibration and printing

Each monitor ages and changes its display properties. This is why graphics monitors, which require an absolutely constant image display over the entire service life, must be regularly calibrated and adjusted. With the free calibration software ColorNavigator 7 from EIZO, the ColorEdge CS2740 can be adjusted within 90 seconds (measured with a MacBook Pro and EX4), easily and without any losses. This is to ensure that the same image still looks the same on the monitor five years from now.
More information on the EIZO ColorNavigator

The free Quick Color Match software helps users, even without in-depth expertise in colour management, to see on the monitor how their images will look when printed on their Canon or Epson inkjet printer at home. In this way, the images can be optimised for the special properties of the selected photo paper even before printing, which helps users avoid expensive misprints.

HDR gamma support

EIZO offers optional HLG and PQ curves for the CS2740 as part of the calibration with ColorNavigator. The optimized gamma curves make images appear more realistic compared to SDR, just as the human eye perceives the real world.

For optimized color reproduction

EIZO microchip

The CS2740 has a high-quality microchip (ASIC, Application-Specific Integrated Circuit), which EIZO developed especially for the special requirements involved in work demanding high colour accuracy. This microchip is the brain of a ColorEdge as it guarantees the precise, uniform and constant image display that is the hallmark of EIZO.

Variety of ports

Best connectivity

Cutting-edge connectivity with USB-C

Image signal, USB data transfer as well as power supply with up to 60 W, all this and more can be realised with a single USB-C cable. This makes the ColorEdge CS2740 the central dock of the graphic workflow. Peripheral devices such as a mouse, keyboard or printer can be connected directly to the USB-A ports. Mobile devices such as laptops or tablets can even be charged via the USB-C cable with up to 60 W via the USB-C cable. In this way, a laptop and CS2740 can be turned into a fully-fledged desktop workstation with a quick flick of the wrist.

Connectivity_USB-C_ColorEdge_EN.jpg

One monitor, many ports

The CS2740 supports a wide range of video formats via USB-C, HDMI and DisplayPort interfaces. This means that the monitor can not only be integrated into PC-based workflows but can also be used with HDMI feeders.

Two PCs, one control

KVM switch

It's never been easier to operate different PCs with a single mouse and keyboard. With its USB upstream ports, the CS2740 has a built-in KVM (Keyboard Video Mouse) switch. The monitor automatically links the mouse and keyboard to the currently active source computer. This means, for example, that a desktop PC and a laptop or a work and home PC can be operated on the same combination of monitor, mouse and keyboard. This ensures uninterrupted work and a tidy workspace.

Ergonomics

Working in a relaxed manner

For the sake of the eyes

Flicker free

The monitor is flicker-free at every brightness setting. This is great for users, as their eyes will not tire as quickly, allowing them to work in front of the screen for longer periods of time without fatigue.

Anti-glare coating: more image, less reflection

The CS2740 offers a perfect, non-glare surface. By minimising glare by diffusing the reflected light, the CS2740 effectively protects your eyes from straining. This keeps your eyes from getting as tired and allows you to sit comfortably in front of the monitor, without having to sit in a forced position to prevent glare.

Ergonomics_Anti-glare.png

Flexible stand

Our screens offer continuous height adjustment. Depending on the model, they can even be lowered to the base plate of the stand. This guarantees the best possible ergonomics, regardless of whether the user is sitting or standing in front of the screen. You can also swivel, rotate and tilt the monitor base to the position that is most comfortable for your posture.

The CS2740 can also be rotated into the portrait format, which is a great advantage for tethered shoots of people in the portrait mode, for example.

FAQs

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.

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.
