ATEN CS1732B (2 Computers / PS/2-USB VGA+Audio / Desktop KVMP Switch with OSD / $151.34) Review
The ATEN CS1732B is a 2-port PS/2-USB VGA/Audio desktop KVMP switch with multilingual OSD, 2.1 surround sound audio support, and a 2-port USB 2.0 peripheral hub, with custom KVM cables included.
This is ATEN's long-running 2-PC VGA switch, still sold new today - a step below the newer CS1922 (DisplayPort) in video standard, but with the OSD, dual PS/2-or-USB console support, and included cabling that some VGA-era buyers still specifically look for.
A Long-Running Desktop Classic
The CS1732B has been part of ATEN's desktop KVM lineup for years and remains in active production, pairing a metal housing with four switching methods: pushbutton, hotkey, OSD, and mouse.
Audio Pass-Through on a Budget VGA Switch
Unlike many entry-level VGA switches, the CS1732B carries 2.1 surround sound audio switching alongside video and USB, useful for desks running two machines that each need speaker output without a separate audio switch.
Comparison to Alternatives
Versus the ATEN CS1922 already in this catalog - that's a newer 2-port DisplayPort switch with modern video, a better fit for current-generation workstations. Versus the ATEN CS22U also in this catalog - a simpler, cable-style VGA switch without audio or OSD support. Versus the StarTech SV211HDUA2 - an HDMI-based 2-port switch at a similar price point for buyers who've moved off VGA entirely.
