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.
Image and colour accuracy
There are many things that go into creating a high-precision/high-contrast, bright and crisp screen. We constantly refine our monitor technology, use only high-end materials and carefully calibrate every single monitor during production. As a result of these efforts, you can always rely on excellent image reproduction.
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.
The screen 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.
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.
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.
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.
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).
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.
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.
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
A growing number of creative professionals are using their portable computers not just while they are on the go. A powerful laptop is often their only computer, which is why more and more of them want to integrate their portable computer into their office at home or at work. EIZO is addressing this trend with the new ColorEdge graphics monitors.
Image signal, USB data transfer as well as power supply with up to 60 W Watts, 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 Watts 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.
It's never been easier to operate two PCs with a single mouse and keyboard. With two USB upstream ports (USB-C and USB-B), the ColorEdge 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. Switching is then done conveniently with the sensor key on the front of the monitor. This ensures uninterrupted work and a tidy workspace.
ColorEdge monitors bring ergonomics to computer workstations. In addition to alleviating eye and back strain, the monitors also meet the user’s unique requirements. This is because we do not believe that you should have to adjust to your workstation – your workstation should adapt to your needs.
Many monitors flicker imperceptibly. This flickering is not consciously perceived, but it causes the eyes to tire more quickly. That is why EIZO attaches great importance to flicker-free monitors. 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.
Nothing is more distracting than dazzling reflections on the monitor. That is why all EIZO monitors use modern antireflection technology. This does not just protect your eyes from excessive strain, but also saves you from having to assume uncomfortable positions while sitting in front of your monitor.
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.
EIZO considers longevity, sustainability and environmental friendliness to be main components of product quality. That is why our monitors are produced in accordance with international environmental regulations and reduce resource consumption thanks to the long service life they offer. EIZO uses the CS2740 to showcase how image and product quality go hand in hand with responsible planning, material procurement and production. This intrinsic value enables you to make a safe investment in a modern and reliable monitor.
The CS2740 is produced in a socially responsible way. It is free of child labour and forced labour. Suppliers along the supply chain have been carefully selected and they have also committed themselves to produce in a socially responsible way. This applies in particular to conflict minerals. We present a detailed report about our social responsibility annually and voluntarily.
Each CS2740 is manufactured in our own factory, which implements an environmental management system in accordance with ISO 14001. This includes measures to reduce waste, wastewater and emissions, resource and energy consumption, as well as to encourage environmentally conscious behaviour among employees. We publicly report on these measures on an annual basis.
The CS2740 is designed for a long service life that takes into account the entire lifecycle and impact on the environment. It is generally well above the five-year guarantee. Spare parts are available up to five years after the end of production. The monitor’s long service life and the ability to repair it save resources and the climate. When designing the CS2740 we paid attention to reducing resource consumption by using high-quality components and materials and being meticulous in production.
Our innovative service concept sets standards and creates planning security – security that convinces and you can count on. As a result of constant research, further development and painstaking quality control, EIZO is able to offer a five-year guarantee for all ColorEdge models. For you, this means the highest possible investment security and a low TCO (total cost of ownership).
