True black HDR for cinematic depth
This monitor supports DisplayHDR 400 True Black, producing exceptional shadow detail and contrast. With a dynamic contrast ratio of 1,500,000:1, highlights pop without clipping. In practice, dark scenes in films and games retain nuance, while creative work benefits from accurate tonal grading.
Fluid motion for games and video
A 120 Hz refresh rate and 0.03 ms GtG response time minimise blur and smearing. AMD FreeSync Premium Pro synchronises the panel with compatible graphics cards to reduce tearing. So fast-paced content stays sharp, whether you are editing timelines or playing at high frame rates.
One-cable laptop docking and power
The USB Type-C upstream port supports DisplayPort Alternate Mode and delivers up to 90 W of power. Connect a compatible laptop and you get video, data, and charging through a single cable. Also, two downstream USB Type-C ports let you attach accessories without reaching your tower.
Comfortable, adaptable desk setup
The detachable stand offers height adjustment up to 11 cm, tilt from -5° to 21°, and swivel from -4° to 4°. Cable management keeps your workspace tidy, and a Kensington lock slot helps secure the display in shared offices. Because the bezels are slim, multi-monitor setups feel seamless.
Built-in audio that fills the room
Five integrated speakers with 25 W RMS output provide AI-enhanced 3D spatial audio. This creates a wider soundstage than typical monitor speakers, improving immersion for films and calls. For private listening, you can route audio to external headphones via your PC or docking station.
Low blue light and flicker-free viewing
We include Low Blue Light technology and flicker-free backlighting to reduce eye strain during long sessions. The panel’s QD-OLED design maintains colour fidelity while limiting harmful blue emissions. Consequently, you can work comfortably through the day without sacrificing accuracy.
