1. Tackle More with a Spacious Screen and 4K

Work Effectively on a Wide 42.5-inch 4K Screen

The monitor supports 4K (3840 x 2160 pixels) resolution, displaying four times the amount of information than standard Full HD (1920 x 1080 pixels) across a spacious 42.5-inch size screen. This provides more space for flexible arrangement of multiple applications without the obtrusive bezels characteristic of multi-monitor setups.

2. Get Connected. Get Started

The monitor features USB Type-C® connectivity that allows you display video, playback audio, transmit USB signals, supply power to connected PCs, and even transmit a network signal.

This convenient multi-purpose connectivity makes it faster and easier to connect your laptop when moving between workstations or working away from the office.

USB Type-C equipped PCs Compatibility information

Power Delivery

The 94 watt power delivery via USB Type-C reliably charges laptops or small desktop PCs. This eliminates the need for a laptop’s bulky power supply unit, freeing up space in your bag and on your desk.

Power Delivery EV4340X EV3450XC

Stable Network Connection

While many modern laptops are not equipped with a dedicated LAN port, the monitor has one directly built in for a wired connection. Connecting any laptop via USB Type-C allows access to the network through the monitor. This allows you to conduct conference calls or data transfers reliably and at high speed.

EIZO MAC Address Clone Utility software temporarily assigns the MAC address of a connected PC to the monitor, granting network access to authenticated devices, and preventing network access from unauthenticated devices.

Directly Connect Peripherals

While many modern laptops are designed to be thinner and more portable, they often have limited connectivity options for peripherals. Connecting a laptop to the monitor via USB Type-C provides access to a hub with two USB Type-A ports and one USB Type-C port for easily connecting an external keyboard, mouse, or storage device.


3. A Better Meeting Experience

Many organizations are adopting open-space meeting areas for fostering engagement and inclusivity.

The monitor includes many features and functions to facilitate an efficient and lively collaborative environment.

Make Open Meetings More Efficient

The Picture-by-Picture (PbyP) function allow the monitor to receive up to four video signals to be displayed side-by-side on one large screen. A switch on the front of the monitor allows you to select your preferred layout from a choice of 12. The monitor also has a Picture-in-Picture (PinP) function. This enables more streamlined screen sharing for efficient presentations and meetings.

Slim Design with Open Atmosphere

The monitor’s slim design allows you to maximize desk space while enjoying the spaciousness of the large screen. At 96.6 cm wide and 22.5 cm deep, it fits neatly on most standard-sized office desks (e.g. 120 cm wide, 70 cm depth). It is also easier to install than multiple monitors and uses fewer cables to keep your workspace tidy.

5. Say Goodbye to Tired Eyes

The monitor is packed with features to help users focus on their work by keeping their eyes comfortable throughout the day.

Auto Brightness Control

To prevent eye fatigue, a brightness sensor called Auto EcoView detects the changes in the ambient brightness that occurs throughout the day and automatically adjusts the screen to the ideal brightness level.

Auto Brightness Control 1 EV3450XC

Reduce Blue Light by 80%

Printing work-related documents is becoming less common with the rise of home offices, telecommuting and tighter security measures. Paper Mode reduces the amount of blue light emitted from the monitor, helping to prevent eye fatigue when reading digital documents. When used in conjunction with the Auto EcoView auto-dimming function, blue light is reduced by up to 80%.

Paper mode en EV3450XC

Flicker-Free Viewing

Due to the way brightness is controlled on LED backlights, some people experience flicker on the screen, causing eye fatigue. The monitor uses a hybrid solution to regulate brightness and eliminate perceived flicker without compromising color stability, even at low brightness settings.

Flicker Free EV3450XC

Minimum Brightness of 1 cd/m2

In a dimly lit work environment, a monitor with low brightness settings is more comfortable to use. With its LED backlight, the monitor is adjustable to approximately 1 cd/m², which is less than 1% of the maximum.

Brightness en EV3450XC

Clear View

The monitor uses an LED-backlit IPS (in-plane switching) LCD panel with a wide viewing angle, providing high visibility even when used by multiple people in a meeting.


Glare Reduction

The panel is treated with an anti-glare coating to reduce screen reflections caused by ambient light. This makes the screen easier to see and helps reduce eye fatigue.

Our Environmental Commitment

EIZO considers longevity, sustainability and environmental friendliness to be main components of product quality. That’s why EIZO’s EcoView monitors feature intelligent energy saving features, are produced in accordance with international environmental regulations and reduce resource consumption thanks to the long service life they offer.

Save up to 30% of energy with the EcoView Optimizer

Save electricity without compromising quality: The EcoView Optimizer reduces the background lighting fully automatically for dark images. This reduces electricity consumption by up to 30%. At the same time, the signal is amplified and the colour tone values adjusted. The result: You will enjoy the image quality you are used to but consume less power.

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 0.5 watt in standby mode.

Environmentally and socially conscious production
