ExpertCenter P400 AiO for business productivity

The ASUS ExpertCenter P400 P440VA-DS504T is a 23.8-inch all-in-one computer built for office workloads. It pairs an Intel Core i5-13420H processor with 16GB DDR5 memory and a 1TB M.2 NVMe PCIe 4.0 SSD. Windows 11 Home comes pre-installed for immediate deployment.

Touchscreen, retractable camera

The 1920 x 1080 display covers 100% sRGB and supports ten-point touch input. A retractable webcam slides away when not in use, and the chassis meets MIL-STD 810H durability standards. Connectivity includes Wi-Fi 6E, Bluetooth 5.3, Gigabit Ethernet and USB 3.2 Gen 1 Type-C among other ports.

Upgrade from older AiOs or tower-plus-monitor setups

This unit replaces ageing all-in-ones that lack DDR5 memory, NVMe storage or modern wireless standards. The jump is worth it when a business needs a compact, secure workstation with a privacy-focused camera and BIOS compliant with NIST SP 800-155. It is not suited for buyers who require discrete graphics performance or user-upgradeable components.

Questions about this item

What Wi-Fi standard does the P440VA-DS504T use and what band does it add?

It uses Wi-Fi 6E, which adds the 6 GHz band for less congestion and lower latency on compatible routers.

What VESA mount pattern does the 23.8" ExpertCenter P400 support for wall or arm mounting?

The chassis follows the 100 x 100 mm VESA pattern, so any standard 100 mm mount or arm will attach directly.

How is the retractable privacy camera activated, and what mistake do users make the first time?

Slide the physical shutter on the top bezel to expose the lens; users often forget to slide it open and wonder why the camera stays black.
