ATEN 4-poorts VGA videosplitter (450 MHz)

The ATEN VS134 Video Splitter VGA allows a single VGA source to be duplicated to four separate VGA displays. Designed for environments that require the same analog video signal shown across multiple monitors, the unit supports a maximum resolution of 1920 x 1440 and provides a 350 MHz bandwidth to preserve image detail and color fidelity. The splitter uses a 15-pin HDB male input and four 15-pin HDB female outputs, and its compact housing (229 x 125 x 51 mm) simplifies placement in desktops, AV racks or near source equipment.

Advantages

The ATEN VS134 delivers consistent analog video distribution with even signal output across four ports, reducing the need for additional distribution amplifiers. Its 350 MHz bandwidth and support for up to 1920 x 1440 resolution help maintain clear resolution and color performance for VGA sources. The compact metal enclosure and straightforward connectors make installation and integration into existing VGA-based setups fast and predictable.

Suitable for

• Conference rooms where the same presentation must be shown on multiple screens
• Classrooms and lecture halls for mirroring a teacher's computer to several monitors
• Retail displays that require identical signage on multiple VGA monitors
• Control rooms and monitoring stations with multiple display outputs

How to use

Connect the VGA source (computer, laptop, or other VGA device) to the 15-pin HDB male input on the ATEN VS134 using a standard VGA cable. Connect up to four VGA monitors to the female output ports with compatible VGA cables. Power the unit according to the manufacturer's instructions and set the source device to the desired resolution, up to 1920 x 1440. Verify each display receives the duplicated signal and, if necessary, adjust monitor settings such as brightness, contrast and tracking to optimize image quality.

Recommendations

For best results, use high-quality shielded VGA cables and keep cable lengths within recommended ranges to minimize signal degradation. When operating at higher resolutions, verify that connected monitors support the target resolution and that the source device's video output is configured accordingly. Avoid routing VGA cables near large power sources or strong electromagnetic interference to preserve signal clarity.
