The ATEN CS1644A is a 4-port USB DVI dual-link KVMP switch that lets one keyboard, mouse, two DVI monitors, speakers and microphone control four computers, at up to 2560 x 1600 at 60 Hz (1920 x 1200 at 120 Hz for 3D). It suits dual-screen workstations in design, finance and engineering.

A 2-port USB 2.0 hub shares printers and storage, and KVM, USB and audio focus can be switched independently. Switching works by hotkey, front push-button or mouse, with auto-scan; a daisy-chain port links two CS1642A/CS1644A units for quad-view setups.

Compatibility note: Connections are DVI-I; HDMI or DisplayPort sources and monitors need suitable adapters. Four KVM cable sets (DVI-D dual-link + USB + audio, 1.8 m) and four DVI-D dual-link cables are included.

Key Features

Two DVI-I heads at up to 2560 x 1600 each, HDCP compliant, with support for digital and analogue (DVI-I) monitors.
 
Independent USB and audio switching
Keep audio or a USB printer on one computer while the keyboard, mouse and video move to another.
 
Mac and Sun keyboard emulation
PC keyboard combinations emulate Mac and Sun keys, making mixed-platform desks easier to manage.

Frequently Asked Questions

Is the ATEN CS1644A single-link or dual-link DVI?
Dual-link: ATEN specifies up to 2560 x 1600 at 60 Hz per display.
Can I use HDMI monitors with the CS1644A?
Yes, with DVI-to-HDMI adapters or cables, as long as the resolution stays within the DVI limits; audio uses the separate 3.5 mm speaker ports.
What is the difference between the CS1644A and the CS1642A?
The CS1642A is the 2-port version with the same dual-display dual-link DVI and USB/audio features.
Singular Expert Insight
The CS1644A remains a solid pick for DVI-based dual-screen desks, especially with 30" 2560 x 1600 panels, and the full cable set is in the box. For new builds with DisplayPort monitors, a DP dual-display switch avoids adapters. Compare in our KVM switches range.
✓ Buy it if you run four dual-monitor DVI computers and want independent USB and audio switching.
✕ Skip it if your PCs and monitors are DisplayPort/HDMI only or you need 4K.
→ Also consider the TRENDnet TK-440DP (4-port dual DisplayPort, 4K 60 Hz) or ATEN CS1642A (2 ports).
