StarTech ST124PRO 4-Port High Resolution VGA Video Splitter

The ST124PRO 4-Port High Resolution VGA Video Splitter delivers professional-grade, real-time mirroring of a single VGA source to four displays with pristine image quality. Built for reliability in demanding environments, this video splitter is perfect for classrooms, conference rooms, trade shows, retail demonstrations, and other multi-display setups where consistent, high-resolution visuals are essential. With robust engineering, broad compatibility with standard VGA equipment, and a compact, durable enclosure, you can confidently run dynamic presentations and immersive digital signage across multiple screens without compromising clarity or timing.

• True 4-way VGA distribution – Mirror one VGA source to four independent displays simultaneously, ensuring synchronized content across all screens without manual reconfiguration.
• High bandwidth for sharp images – Designed to handle demanding video signals with a bandwidth of up to 350 MHz, supporting resolutions up to 2048x1536 (UXGA) at 60 Hz across all outputs for crisp text and vivid graphics.
• Reliable signal integrity – Built-in line drivers and precision timing help preserve color fidelity, brightness, and sharpness over multiple cables and displays, even in busy event spaces.
• Durable, compact design – A sturdy metal enclosure withstands everyday use in classrooms, boardrooms, exhibition booths, and retail environments while remaining easy to transport and deploy.
• Plug-and-play convenience – Simple, tool-free setup with standard VGA cables; no software installation required, making it ideal for quick deployments and frequent reconfigurations.

How to install StarTech ST124PRO

• Place the ST124PRO near your VGA source and displays, ensuring enough clearance for ventilation and cable routing.
• Connect the VGA source computer, laptop, or media player to the ST124PRO input using a standard VGA cable.
• Attach four separate VGA cables from the ST124PRO outputs to each display or projector in your setup.
• Power on the source device and each connected display, then select the corresponding input on every display to begin mirroring.
• Configure the source resolution to a setting supported by all displays (or the lowest common resolution) to guarantee consistent output across all four screens. If needed, adjust timing settings or EDID considerations on the source to optimize compatibility.

Frequently asked questions

• Q: What is the maximum resolution I can run on all four outputs?
  A: The ST124PRO supports up to 2048x1536 (UXGA) at 60 Hz across all four outputs, depending on the capabilities of the source and the quality of your VGA cables.
• Q: Do I need an external power supply?
  A: This splitter is designed for plug-and-play operation with standard VGA devices. In typical setups, no external power supply is required. If your installation uses unusually long cables or a weak source, ensure cables are of good quality to maintain signal integrity.
• Q: Can I display different content on each monitor?
  A: No. The ST124PRO is a true splitter, meaning it mirrors the same VGA source across all four outputs. If you need different content on each display, you would require a multi-output matrix switch or separate sources.
• Q: Will the image quality degrade as it is distributed to four displays?
  A: The ST124PRO uses built-in drivers to preserve image integrity. While the displays and cables influence final output, the device is designed to maintain sharpness, color, and timing across all connected monitors when within supported resolutions and cable lengths.
• Q: Is EDID handled automatically?
  A: The splitter aims to maintain compatible timing across outputs. If you encounter display timing issues, ensure all displays can support the source resolution and consider setting a common resolution on the source that all displays can handle.
