The Kramer VM-4HDCP is a compact, high-performance distribution amplifier designed to take a single DVI-D video source and simultaneously distribute it to up to four identical DVI-D displays or projectors. This device is crucial in professional AV installations, digital signage networks, control rooms, and presentation environments where a single computer or video source must drive multiple monitors with zero latency and consistent signal quality. It supports High-bandwidth Digital Content Protection (HDCP), ensuring compatibility with protected content from sources like Blu-ray players, set-top boxes, and computers, making it suitable for applications requiring compliance with copyright protection protocols.

The unit actively buffers and re-clocks the incoming DVI signal, compensating for cable losses and ensuring that each output delivers a stable, pixel-perfect copy of the source. It supports high-resolution video formats, including full HD 1080p and beyond, with a bandwidth sufficient for detailed computer graphics. Operation is typically plug-and-play, requiring no configuration; it automatically syncs to the source resolution and replicates it across all outputs. The device is housed in a small, durable metal enclosure that can be discreetly placed on a desk, mounted behind a display, or integrated into a rack using optional hardware.

By using a distribution amplifier like the VM-4HDCP, installers can avoid the signal degradation and reliability issues associated with daisy-chaining displays or using passive, non-amplified splitters. It ensures that all displays receive an equal and strong signal, maintaining image integrity over longer cable runs. This makes the Kramer VM-4HDCP a reliable and essential tool for creating multi-screen visual experiences from a single source in boardrooms, retail stores, museums, and command centers.
