2. Contoured to Your Workstyle with an Ultrawide, Curved Screen
More Space, Seamless Viewing
This 34.1‑inch ultrawide, curved monitor features a UWQHD resolution (3440 x 1440 pixels) with a 21:9 aspect ratio, delivering 2.4 times the resolution of Full HD (1920 x 1080 pixels). It provides an expanded workspace for flexible arrangement of multiple applications without the obtrusive bezels characteristic of multi-monitor setups.
See Everything at a Comfortable Distance
When you sit close to a large monitor, the far edges naturally fall farther from your eyes. A curved monitor brings those edges gently toward you, creating a more uniform viewing distance that enhances visibility, focus, and immersion.
3. One Screen, Multiple Devices
Convenient Multi-Input Connection
The Picture-by-Picture (PbyP) function enables simultaneous display of two connected PCs on a single screen, creating a space-saving workspace without the need for multiple monitors. Input switching can be quickly operated via the monitor’s front buttons or keyboard hotkeys, supporting an efficient dual-PC working environment.
One Keyboard and Mouse Across Multiple Computers
The built-in KVM switch function allows you to share a single USB mouse and keyboard across multiple computers. Simply connect them to the monitor’s USB hub and switch control between computers using the monitor’s front buttons or keyboard hotkeys.
Hotkey operation is available only in PbyP display mode.
Preset for Video Production
The monitor includes a preset for BT.709, the standard for HD video production, for content creation and video preview tasks. You can switch display modes easily using the monitor’s front buttons.
4. Get Connected. Get Started.
The monitor’s USB Type‑C® connection transmits video, audio, USB data, power, and even network signals through a single cable. This all‑in‑one solution makes docking your laptop quick and effortless, making it ideal for hot-desking or home offices.
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.
Stable Network Connection
The monitor has a built‑in LAN port for a stable wired connection. When you connect laptop via USB Type‑C, it can access the network directly through the monitor, enabling you to conduct conference calls or data transfers reliably and at high speed.
With the MAC address pass-through function, the monitor temporarily uses the authenticated MAC address of the connected PC. This allows seamless network access in shared office environments without the need for additional software.
Directly Connect Peripherals
As modern laptops become thinner and more portable, their peripheral connectivity is increasingly limited. The monitor includes a 4‑port USB hub with an additional USB Type‑C port and three USB Type‑A ports for convenient connection to peripherals such as a keyboard, mouse, or USB storage devices.
5. Aesthetically Pleasing Design
The monitor’s slim bezel design embraces minimalism for an immersive experience.
Colour Coordination to Suit Your Workspace
The monitor cabinet is available in white or black. Matching white or black stands and cables are available for a coordinated look. You can choose white for a bright and inviting tone, or black for a chic and relaxed tone.
Connectivity and Flexibility
The monitor is equipped with USB Type-C, DisplayPort™, and HDMI® video inputs, allowing connection to a wide range of PCs. This makes it ideal for hot‑desking environments and open workspaces.
6. Say Goodbye to Tired Eyes
The monitor includes features that help reduce eye strain throughout the day, supporting better focus and comfort.
Auto Brightness Control
To prevent eye fatigue, a brightness sensor called Auto EcoView detects the changes in the ambient brightness that occur throughout the day and automatically adjusts the screen to the ideal brightness level.
Reduce Blue Light by 80%
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%.
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.
Minimum Brightness of 1 cd/m²
In a dimly lit work environment, a monitor with low brightness settings is more comfortable to use. The monitor is adjustable to approximately 1 cd/m², which is less than 1% of the maximum.

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
EIZO uses the FlexScan monitors 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.
Socially responsible production
The FlexScan monitors are 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.

Environmentally and climate friendly
Each FlexScan monitor 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.

Sustainable and durable
The FlexScan monitors are 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 FlexScan we paid attention to reducing resource consumption by using high-quality components and materials and being meticulous in production.
The packaging of the FlexScan consists of cardboard box made of 85% recycled paper, while the transport padding is even 100% recycled material.
