Image quality
Precise, high-contrast, bright and crisp screen
The EV4340X supports 4K (3840 x 2160 pixel) resolution, displaying four times the amount of information than standard Full HD (1920 x 1080 pixel), and more than two times the amount than WQHD (2560 x 1440 pixel) monitors. 
4K resolution for ultra-sharp texts and images
Whether control room, control room or retail workstation – the FlexScan EV4340X with 4K Ultra HD resolution supports your work with its exceptional display quality. Texts and graphics are presented on the 42,5 inch monitor thanks to a native resolution of 3840 x 2160 (4K UHD) pixels and 104 ppi (pixels per inch) clearly and precisely. 
Maximum image quality thanks to the IPS panel
The monitor is capable of all three key elements of excellent image quality: excellent resolution of 3840 x 2160 (4K UHD) pixels, maximum contrast of 1000:1, and stable brightness of up to 350 cd/m². That means you will experience razor-sharp text contours, brilliant graphics, and clear images. Thanks to the high-quality IPS panels with LED backlight, contrasts and colours remain stable from every viewing angle. 
Precise color control
An image can only be perfect if the colors are, too. This is why EIZO monitors have a 10-bit look-up table at a minimum, which allows the color information to be assigned much more precisely than with conventional 8-bit LUTs. The finest color gradations ensure that gradients are always perfectly displayed, while also offering customised adjustment options. For example, you can adjust the white balance from 4000 K to 10 000 K in 500-K intervals. 
Overdrive to quickly change images
The overdrive function accelerates the switching time so that gray-grey changes take place in just 5 ms on average. You can watch movies and fast image changes without annoying afterglow. When scrolling and positioning windows or images, the display is legible in fractions of a second – faster than it can be perceived. Power consumption and energy efficiency are always in view. Variety of ports
Best connectivity
One monitor, many ports
It couldn’t be simpler: you can connect most signal sources such as computers, video decoders or even supply lines from server rooms directly to the monitor. This is because the EV4340X has various signal interfaces and connections, including a headphone connection and USB down interfaces. This makes integration into the intended installation easier. 
Two PCs, one control
KVM switch
It has never been easier to operate different PCs with a single mouse and keyboard. Thanks to the USB upstream ports, the EV4340X has an integrated KVM (Keyboard Video Mouse) switch. The monitor automatically links the mouse and keyboard to the currently active source computer. For example, connected computers can each be operated on the same combination of monitor, mouse and keyboard. This ensures uninterrupted work and a tidy workspace. 
Solutions for remote visualization and video streaming
For the use of the EV4340X in video surveillance solutions, we recommend the optional IP decoding box from EIZO. It enables the computer-free connection of multiple IP cameras or a video management system in security and surveillance environments. The IP decoding box from EIZO is particularly suitable for monitor walls. Neither computers nor software are required for connection to the video network. The compact box can be attached to the EV4340X using a VESA mount and adapter plate to save space. Comprehensive functionalities and compatibilities make the IP decoding box from EIZO a very flexible and space-saving solution module for the output of video streams. You can find more information about our IP decoding solutions for video surveillance in this video
Cutting-edge connectivity with USB-C
Video and audio playback, fast data transfer including network signal and power supply for connected devices – all this and more can be realized with a single USB-C cable. Particularly practical if a notebook with a USB-C or Thunderbolt interface needs to be connected to the monitor. The 94 W power supply via USB-C reliably charges small computers or notebooks. This eliminates the need for an additional computer power supply unit.
We have tested a small selection of different devices and the compatibility between monitor and computer for you and described them on the international EIZO website.
Stable network connection
LAN port
The monitor has a dedicated LAN port to ensure a stable wired network connection. Laptops and PCs require only one USB cable to be connected to the EV4340X to gain network access via the monitor. This is particularly advantageous for laptops that do not have a LAN connection and allows stable data transfer, which is required for video conferences, for example. As a network device the monitor has its own MAC address. Optionally, the “EIZO MAC Address Clone Utility” software for Windows can temporarily assign the MAC address of the connected PC to the monitor. This transparency grants authenticated PCs network access through the monitor.
Software and ease of use
Features for greater comfort
Picture-by-picture: everything at a glance
With the picture-in-picture function (PbyP), the monitor can display up to four video signals side by side on its large screen. You can select your preferred picture arrangement from 12 layouts using the button on the front of the monitor or the remote control. This enables optimized screen usage for efficient operation with more than one source. 
Picture-in-picture layouts with 2 picture signals
Picture-in-picture layouts with 3 picture signals
Picture-in-picture layouts with 4 picture signals
Picture-in-Picture
Picture-in-Picture mode allows you to display two image signals at the same time – a main image and a reduced-scale image from another signal source inserted into the main image. The size and position of the second window can be varied. 
Preset color modes: optimized display at the touch of a button
Preset colour modes optimize the viewing of graphics, text and tables or video. You can set the respective preset for brightness, gamma correction and color temperature at the touch of a button. Electrostatic switches are integrated into the front of the EV4340X instead of mechanical buttons. This ensures ease of use while also giving the monitor an extremely elegant look. With the Button Guide, you have all functions at a glance. One touch of the control panel is enough, and the function assignment of the buttons is displayed. Your advantage: clarity of operation and a clean, uncluttered design.
The speakers and all the controls are also built into the bezel, pointing forward in the direction of the user. They are fully integrated into the monitor’s flat, nearly frameless design to offer an excellent user experience.
Remote control included
The supplied remote control can be used to control the volume, brightness, signal input, picture-in-picture and other settings as well as to switch the monitor on and off. This is useful if the buttons on the front of the monitor cannot be reached, e.g. for wall installations. Monitor control and administration
Screen InStyle
In addition to the on-screen menu, you can conveniently control the EV4340X by using the Screen InStyle software on a PC. The configuration options include color reproduction, energy saving options, and ergonomic functions. In multi-screen systems, the settings can be applied synchronously to all connected screens with Screen InStyle. 
Software for monitor control by administrators
Screen InStyle Server
System administrators can centrally manage and control monitors connected in the network with Screen InStyle installed using the Screen InStyle Server application. This optimises power consumption and simplifies asset management of the monitors. Company-wide default setup
Monitor Configurator
Workload reduction for administrators: The software allows you to create a default setup for all relevant monitor settings. This setup can be distributed to the connected monitors via the local network which facilitates the roll-out process. 
Design
A good figure in any set-up
Elegant design
The appearance of a monitor makes a significant contribution to creating a pleasant working atmosphere. With its fine, practically frameless design and ergonomic functions, the monitor blends naturally into the intended installation. In addition to elegant black, the housing is also available in white with matching white cables. 
Ergonomics
Working in a relaxed manner
Easy on the eyes with Auto EcoView
At day, at night, bright, dark: No matter when and how you work, the Auto EcoView function continuously measures changes of the ambient light and optimises the monitor with ideal brightness values automatically by using a sensor. The benefits: Annoying glare is reduced, your eyes will not get tired as quickly. A special two-point control takes into account the brightest and darkest environment over the course of the day with the respectively desired screen brightness. Another plus: the automatic brightness adjustment can significantly reduce power consumption. Of course, you can also continue to configure the monitor manually. EcoView Index is used for orientation on how environmentally friendly and economical your settings are.
For the sake of the eyes
Flicker free
To help protect your eyes, EIZO has developed a hybrid technology to control the backlight. This combines the benefits of the otherwise standard PWM (pulse width modulation) and DC (direct current) control. The PWM control uses much higher frequencies than standard PWM methods. The result: a flicker-free viewing experience while maintaining picture quality and colour stability. In addition, compared to pure DC control, you can adjust the brightness to less than 1% of the maximum value in darkly lit rooms. The benefit: Your screen remains free from flicker and glare even under these conditions. The flicker-free and low blue light content of the EIZO FlexScan monitors is certified by TÜV Rheinland.
Anti-glare coating: more image, less reflection
The EV4340X offers a perfect, non-glare surface. By minimising glare by diffusing the reflected light, the EV4340X 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. Stand and VESA mounting option
With its stable, non-adjustable stand, the monitor stands securely in its installation location. For VESA mounting, the EV4340X has VESA100 and VESA200 screw connections. Sustainability
Environmentally and socially conscious production
Save energy effortlessly
EIZO monitors are equipped with sophisticated energy-saving functions. Up to 50% less power consumption
The Auto EcoView function automatically adjusts the brightness of the screen to changes in ambient light. This saves electricity compared to a monitor that is operated at a constant brightness. Of course, you can still adjust the monitor manually. The EcoView index serves as a guide to how environmentally friendly and economical your setting is.
The EcoView Optimizer automatically reduces the backlight in dark images, thereby reducing power consumption. At the same time, the signal is amplified and the color tone values are adjusted. The result: you experience the usual image quality with lower consumption.
These EcoView technologies reduce overall power consumption by up to 50%* compared to the display at maximum brightness. Another plus: the automatic brightness adjustment can be easy on your eyes.
* Typical power consumption when no USB Power Delivery is used.
Zero-watt consumption thanks to the power switch
The monitors have an integrated mechanical power switch, which is extremely practical and energy-saving: If you switch off the monitor using the power switch, the device will stop consuming any power at all. Moreover, it consumes a maximum of 0.4 watt in standby mode.
Comprehensive product sustainability
FlexScan monitors from EIZO are produced in accordance with international environmental regulations and in a socially responsible manner. Suppliers along the supply chain are carefully selected and have also committed themselves to this responsibility. During the design process, attention was paid to the low use of resources with high-quality components and materials as well as careful production. In addition, FlexScan monitors protect resources and the climate thanks to their long service life, warranty and repairability. Read detailed information about product sustainability here.
Environmentally friendly use of materials
The EV4340X is made of 75% recycled plastic. This reduces the amount of plastic waste entering the environment, conserves resources and promotes the reuse of materials. Reducing the use of volatile organic compounds (VOCs) in material production, such as those found in certain paints and varnishes, is also of global interest.
Through years of research, EIZO has succeeded in achieving a smooth, nearly homogeneous color and texture in its monitor housings without the use of varnish.
Environmentally friendly packaging
For the packaging of the EV4340X, EIZO uses a padding made of moulded pulp cellulose. The material is made from recycled cardboard and paper and has a much lower environmental impact when disposed of than traditional polystyrene or plastic. All cables are stored in a cardboard compartment instead of being individually packed in plastic bags.
