Kramer VP-400K 1:4 Computer Graphics Video Distribution Amplifier

The Kramer VP-400K is a high-performance distribution amplifier designed for computer graphics signals, delivering pristine, identical outputs to four displays or projectors from a single source. Built for reliability in professional environments, it buffers each output to preserve signal integrity, minimizes cross-talk, and maintains accurate timing across all connected devices. With its wide bandwidth, UXGA-ready resolution support, and HDTV compatibility, the VP-400K is a versatile solution for classrooms, conference rooms, control rooms, digital signage, and multimedia installations that demand synchronized, high-quality video across multiple displays.

• The VP-400K provides 1 input and 4 identical outputs, with dedicated buffering and isolation on every channel. This ensures that loading on one display does not degrade the signal quality delivered to the others, delivering uniform brightness, color, and timing across all connected displays.
• With a high bandwidth of 400 MHz (-3 dB), the VP-400K preserves subtle details in computer graphics signals, reduces high-frequency roll-off, and minimizes edge artifacts. This makes it ideal for fast-refresh-rate content, dense vector graphics, and sharp text that remains legible when distributed to multiple screens.
• Support for resolutions up to UXGA and beyond means the VP-400K can handle modern PC graphics and high-resolution imagery. It is compatible with a wide range of displays, including traditional CRTs, LCD panels, and digital projectors, enabling seamless integration into varied setups without sacrificing image fidelity.
• HDTV compatibility expands the VP-400K’s usefulness beyond standard computer graphics. It can distribute video content suitable for presentation rooms, retail environments, and multimedia installations that blend computer-generated graphics with HDTV-grade content, all while maintaining consistent signal integrity across all outputs.
• ID Bit Control adds installation flexibility, allowing technicians to manage identification and signaling in complex, multi-display configurations. This feature helps prevent signal misrouting and EDID-related issues in dense setups where multiple distribution amplifiers or video routers are deployed.

How to install Kramer VP-400K

• Prepare your setup by ensuring all displays and the computer graphics source are ready and powered off before connecting cables.
• Connect the video source to the VP-400K input using the appropriate VGA/RGB cable from your graphics workstation or PC. Ensure secure connections at both ends to prevent signal loss.
• Attach four identical output cables from the VP-400K outputs to the corresponding displays or projectors in your installation. Use high-quality, shielded cables to minimize interference and preserve signal integrity across all connections.
• Power the VP-400K by plugging in the power supply. If the unit offers an on/off switch, power it on and verify that all displays are receiving a signal with consistent timing and image quality. Ensure that the power source is stable to avoid performance fluctuations.
• If your installation uses ID Bit Control, configure the identification settings according to your multi-display layout. This helps maintain proper signal routing and EDID compatibility in setups with multiple distribution devices or video routers.
• Test the system by displaying the same source content across all connected displays. Check for uniform color reproduction, sharpness, and synchronization. If discrepancies appear, re-check input cables, run lengths, and EDID management to ensure consistent results.
