Video splitter ATEN VS138A-AT-E — VGA input to 8x VGA outputs, 2048x1536, metal housing, 5V

ATEN VS138A-AT-E is an 8-port VGA video splitter that duplicates a single VGA source to eight VGA displays with support for up to 2048 × 1536 resolution. Housed in a black metal chassis and powered by a 5 V adapter with typical consumption of 2.25 W, the unit is designed to deliver identical, stable VGA outputs for presentations, classrooms, retail displays and multi-monitor installations. The device is cascadable to three levels to expand distribution and can extend transmission distance up to 30 m (98.5 ft) while maintaining signal quality for multisync formats including VGA, XGA, SVGA, UXGA, QXGA and WUXGA.

Advantages

The VS138A-AT-E provides reliable duplication of one VGA source to eight outputs without signal configuration on each display, ensuring uniform image delivery across multiple screens. Its metal housing offers mechanical durability and shielding against interference, and the low power consumption reduces operating cost. Cascadability to three levels allows scaling to larger installations and the device supports extended cable lengths to reach distant displays without additional active equipment.

Suitable for

• Classroom and lecture halls for simultaneous display to multiple screens
• Corporate meeting rooms and overflow areas for consistent presentation mirroring
• Retail and digital signage installations requiring identical VGA content on multiple monitors
• Financial trading floors for remote display of market information
• Public broadcast or demonstration setups where long cable runs are needed

Key specifications

• Video input/output type: VGA input duplicated to 8 VGA outputs

• Cascadable levels: up to 3 levels for wider distribution
• Maximum transmission distance: up to 30 m (98.5 ft) for VGA signal
• Chassis material and color: metal housing, black finish
• Power requirements: 5 V external adapter, typical power consumption 2.25 W
• Weight: approximately 0.69 kg

How to use

Connect the VGA source (PC, laptop or other VGA output device) to the splitter's VGA input. Use standard VGA cables to connect up to eight displays to the splitter outputs. Plug the supplied 5 V power adapter into the unit and a suitable mains outlet. Power on the source and displays; the splitter duplicates the incoming VGA signal to all connected outputs automatically. For larger systems, cascade additional splitters up to three levels, keeping cable lengths and signal integrity in mind.

Usage recommendations

For best image quality, use high-quality shielded VGA cables and avoid excessively long cable runs beyond the recommended 30 m per leg. When cascading splitters, ensure each stage is powered and verify resolution settings on the source to match the supported maximum of 2048 × 1536. Locate the metal-housed splitter away from strong electromagnetic sources to minimise interference.
