The Kramer VM-4DP is a high-performance 1:4 DisplayPort distribution amplifier engineered for professional AV installations requiring pristine 4K video duplication across multiple monitors or projectors. Supporting DisplayPort 1.2 specifications, this unit accepts a single input and drives up to four simultaneous outputs at resolutions up to 3840x2160 at 60Hz with 4:4:4 color sampling. The amplifier handles multi-channel audio formats including LPCM 7.1, Dolby TrueHD, and DTS-HD Master Audio, ensuring complete audiovisual synchronization for home theaters, simulation rooms, and corporate boardrooms. Housed in a compact, rugged enclosure, the VM-4DP includes front-panel LED indicators for power, input lock, and per-output status.

The device employs active reclocking and signal regeneration technology to overcome signal degradation over long DisplayPort cable runs up to 15 meters for 4K content. For installations requiring more than four displays, multiple VM-4DP units can be daisy-chained by connecting an output from the first unit into the input of a second, allowing virtually unlimited expansion without requiring additional matrix switchers. The VM-4DP supports DP++ (Dual-Mode DisplayPort), enabling passive adapter cables for HDMI or DVI output conversion, adding deployment flexibility when mixing display technologies.

The unit arrives factory-sealed in its original Kramer box, including all standard accessories such as the power adapter, mounting brackets, and a printed quick-start guide. Passive cooling eliminates moving parts, ensuring silent, maintenance-free operation for always-on digital signage applications. Kramer's built-in automatic equalization adjusts for cable quality and length variations, while the compact depth of 6.5 inches permits installation beneath desks, behind displays, or within standard 19-inch racks using the included rack ears.
