Curved comfort for long sessions
The 1900R curvature matches your natural field of view. Because the screen wraps around you, head movement reduces and eye strain eases. In practice, the anti-glare surface keeps reflections low under office lighting. This design supports clear focus during extended work.
A single-cable laptop hub
Two Thunderbolt 4 upstream ports and a USB-C DisplayPort Alternate Mode simplify connectivity. We include 5 USB-A and 3 USB-C downstream ports, plus an RJ-45 Ethernet socket for stable networking. USB Power Delivery up to 90 W charges a compatible laptop through one cable. Your desk stays organised and ready for meetings.
Colour you can trust for creative work
The IPS panel delivers 1.07 billion colours with 98% DCI-P3 coverage. It also covers 100% of sRGB for consistent web and print workflows. Because colour accuracy matters, each monitor is factory-tuned. Expect precise shades and smooth gradients across the ultrawide canvas.
Smooth motion at 120 Hz
A maximum 120 Hz refresh rate makes scrolling, dragging, and previews feel fluid. The 5 ms fast response time helps reduce ghosting on fast-moving content. This is useful for timeline editing and detailed UI work. It remains gentle on the eyes across the day.
Eye comfort features
We include Low Blue Light technology and Flicker-free technology to support visual comfort. The 5-Star Eye Comfort rating signals reduced strain during long shifts. Because the panel is anti-glare, it handles bright rooms well. The result is a calmer viewing experience.
