Secure KVM for dual DisplayPort workstations

The ATEN CS1144DP4 is a four-port KVM switch designed for environments that require strict desktop isolation. It lets a single keyboard, mouse and dual DisplayPort monitors control four separate computers without data leakage between channels. The unit meets PSD PP version 4.0 requirements for high-assurance deployments.

Passive cooling keeps the unit silent

With no moving parts the switch operates completely silently in normal use. Power is supplied through the included external adapter, so the device itself draws minimal current and generates negligible heat. This makes it suitable for quiet offices, control rooms or any setting where acoustic signature matters.

Sustained switching maintains signal integrity

The internal architecture is built for continuous operation rather than brief bursts. Video signals stay stable during extended sessions across all four ports, and USB peripheral emulation remains consistent so connected systems never lose keyboard or mouse focus. The design targets reliable performance throughout long duty cycles.

Questions about this item

How do I install the CS1144DP4 secure KVM and what step is commonly missed?

Connect each computer to a dedicated port using DisplayPort and USB cables, then attach displays and peripherals to the console side; the step often missed is verifying the PSD PP v4.0 compliance label on every cable before powering on.

What maintenance or replacement will the CS1144DP4 need over time?

The unit has no user-serviceable parts; only the external power cord or cables may need replacement if damaged, while the switch firmware remains fixed per PP 4.0 certification.

What limit appears first on the CS1144DP4 during sustained operation?

The four-port architecture sets the maximum number of connected computers at four, so the port count is the first hard limit reached when expanding the setup.
