ATEN CS64U (4-Port USB VGA/Audio Cable KVM Switch, 1.8m / $98.00) Review
The ATEN CS64U is a 4-port USB VGA/audio cable KVM switch built for desktop use with 1.8m built-in cabling.
It's the 4-port sibling to the CS22U, but with audio switching added and hotkey control instead of just a physical selector. If you're running four VGA-era or budget machines off one monitor with sound, this is a sensible cable-style pick.
Four Computers, One VGA Monitor
The CS64U is a bus-powered, cable-style KVM with built-in 1.8m cables for all four computer connections, so there's nothing extra to buy. Max resolution is 2048x1536@60Hz over VGA with DDC2B support for proper EDID handshaking with the monitor.
Hotkeys and Audio
Unlike the CS22U, the CS64U supports hotkey switching plus an Auto Scan mode that cycles through active computers automatically. A 3.5mm audio jack on the console and each computer port lets sound switch along with the KVM focus.
