Frequently Asked Questions
What is a quad-head HDMI KVM extender and how does it work?
A quad-head HDMI KVM extender like the SmartAVI HDX-XT-4P transmits video, keyboard, mouse, and audio signals from a source computer to remote displays and peripherals over long distances using standard network cabling. The sender unit (transmitter) connects to your computer, while a receiver unit at the remote location connects to displays and peripherals. This enables control of multiple displays from a distance without signal loss.
How far can the SmartAVI HDX-XT-4P extend HDMI signals?
The SmartAVI HDX-XT-4P extends HDMI signals up to 330 feet (100 meters) over CAT5e, CAT6, or CAT7 cabling. This extended range makes it ideal for large facilities, broadcast studios, and control rooms where displays need to be positioned far from the source equipment.
Does the 4K HDMI extender support multiple displays simultaneously?
Yes, the quad-head design supports up to four independent HDMI video streams simultaneously, allowing you to extend multiple 4K displays from a single source. Each HDMI output can drive a separate display, making it perfect for multi-monitor workstations and control room environments.
Is USB 2.0 fully functional through the HDMI KVM extender?
Yes, the SmartAVI HDX-XT-4P provides fully-transparent USB 2.0 pass-through, meaning keyboards, mice, and other USB peripherals operate with zero latency and full compatibility. The USB connectivity is bi-directional, supporting both input and output devices.
