Designed with sustainability in mind

Intentional design in every part

At the heart of our design is a commitment to sustainability. That's why our monitor is crafted with recycled materials from top to bottom, including up to 85% post-consumer recycled plastic⁴, 100% recycled aluminium⁵, 50% recycled steel⁶, and at least 20% recycled glass⁷, making up to 46% recycled content by weight⁸. Using these materials helps reduce waste and lower environmental impact.

Environmental standards

This monitor is certified ENERGY STAR® , meaning it has met high standards for energy efficiency.

Seamlessly modernise your tech

We can help you responsibly and securely retire your legacy IT equipment, regardless of brand, while addressing your sustainability goals.

Packaging with purpose

This monitor ships in a box made from 100% renewable materials. We are reducing plastic waste wherever possible and transitioning to a responsible fibre-based solution⁹. Plus, we're saving over 600 trees each year by using less paper in packaging¹⁰.
