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.

Questions about this item
How do I connect the four VGA monitors to the splitter and which step is most often missed?
Connect the computer to the single HDB-15 male console port, then attach each monitor to one of the four HDB-15 female PC ports. The step most often missed is plugging in the DC 9 V power adapter before turning on the displays.
What maintenance will the VS94A need over time?
No scheduled maintenance is required. Keep the ventilation slots clear and operate within 0 to 50 °C and 0 to 80 % non-condensing humidity. If a monitor port fails, the unit itself must be replaced.
What is the first limit I will hit when running all four outputs continuously at maximum resolution?
The 350 MHz bandwidth ceiling is reached first; it supports 1920 x 1440 at 60 Hz per output, so sustained use at that resolution uses the full available bandwidth.
