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 plastic[4], 100% recycled aluminum, 50% recycled steel, and at least 20% recycled glass, making up to 46% recycled content by weight[8]. 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 modernize 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
