ATEN VS94A 4-Port VGA Splitter KVM Switch

Signal Distribution

The ATEN VS94A is a four-port VGA splitter that takes a single analogue video source and duplicates it across four displays. It suits classrooms, control rooms and public-signage installations where identical content must reach multiple monitors from one computer. The unit accepts a single HDB-15 input and provides four HDB-15 outputs, supporting VGA, SVGA, XGA and UXGA multisync signals up to 1920 x 1440 resolution.

Thermal & Power Profile

The device operates between 0 °C and 50 °C with humidity up to 80 % non-condensing, drawing a maximum of 2.43 W from the included 9 V DC adapter. No active cooling is present, so the metal chassis runs silently and adds negligible heat to a rack or desk. Power consumption remains constant regardless of how many of the four outputs are actively connected.

Sustained-Load Behaviour

Bandwidth of 350 MHz maintains 1920 x 1440 at 60 Hz across all outputs during continuous operation, and the signal can travel up to 65 m without noticeable degradation. Cascading up to three levels expands the system to 64 monitors while preserving the same resolution and refresh rate. The passive design means performance does not throttle over time, making it reliable for all-day broadcasting or monitoring tasks.
