Advanced connectivity and workflow
The E4 series addresses the connectivity challenges of modern hybrid workspaces. USB-C models (ending with CV / CW) feature 90 W USB Power Delivery, enabling single-cable laptop connections that simultaneously power or charge devices and transmit video signals using USB-C DisplayPort Alt mode. The inclusion of DisplayPort output on selected models allows for seamless daisy-chaining of multiple monitors, creating expansive multi-display setups without complex cable management.

The 34-inch ultrawide models introduce built-in KVM switches, allowing users to effortlessly switch between connected devices while sharing peripherals. All models feature four USB-A ports, with some models offering convenient USB-ports on the side, transforming each monitor into a comprehensive docking solution. RJ-45 input on selected docking models (ending with CV / CW) allow network/internet connection to be routed via the monitor’s USB-C port to the connected laptop, for example, therefore providing a secure, reliable connection with just one USB-C cable.

Health, comfort, and performance focussed
Every E4 monitor incorporates TÜV EyeComfort certified hardware-based blue light reduction and Flicker-Free technology for comfortable extended use. Performance remains uncompromised with response times up to 4 ms GtG and Adaptive-Sync technology across the range, while 120 Hz refresh rates on most models provide smoother scrolling and reduced eye strain.

All monitors feature highly adjustable stands with 150 mm height adjustment for 24″ and 27″ models (incl. tilt, swivel, pivot), while 34″ ultrawide models offer 180 mm height adjustment (incl. tilt and swivel). 100×100 mm VESA mount compatibility provides additional workspace flexibility.

Sustainability at the forefront
The E4 series features the TCO Certified, generation 10 certification – covering environmental, social, and circular economy criteria throughout the product lifecycle. The 5-year warranty supports sustainability goals by promoting longer product lifecycles and reducing electronic waste. Each monitor arrives in 100% recyclable paper cushion packaging, further minimizing environmental impact.
