31.5" 4K IPS panel with Ergo Arm
This 31.5 inch monitor uses an IPS panel at 3840 x 2160 resolution and a 16:9 aspect ratio. It reaches 400 nits brightness with a 2000:1 static contrast ratio and 1.07 billion colours with HDR10 support. The 5 ms grey-to-grey response time and 60 Hz refresh rate suit coding and general desktop work. The package includes the Ergo Arm stand for flexible positioning.
Suited for programmers and multi-taskers.
Coding modes and Display Pilot 2 software help developers arrange code windows and reduce eye strain. USB-C daisy-chain support and a built-in KVM simplify two-system setups with a single keyboard and mouse. Integrated lighting adds ambient bias illumination. Competitive gamers who need refresh rates above 60 Hz or adaptive-sync certification should look elsewhere.
90 W USB-C power delivery decides single-cable
The USB-C port supplies up to 90 W of power while carrying video and data, letting many modern laptops run and charge through one cable. HDMI and DisplayPort inputs are also available for additional devices. VESA 100 x 100 mm mounting holes remain accessible if the Ergo Arm is removed.

Perguntas sobre este artigo
Does the monitor need a separate VESA mount or is the Ergo Arm included?
The Ergo Arm is included and attaches to the 100 x 100 mm VESA pattern on the back of the 31.5" panel.
Can I run the 3840 x 2160 60 Hz signal over HDMI and DisplayPort at the same time for a dual-PC KVM setup?
Yes, the KVM switches between the HDMI and DisplayPort inputs while the USB 3.2 Gen 2 hub stays connected to the active system.
How do I confirm the USB-C daisy chain is delivering 90 W to my laptop?
The Display Pilot 2 software reports the active power delivery and shows the 400 nits HDR10 mode when the chain is working.
