NVIDIA VCQ420NVS-X16-DVI-PB Quadro NVS 420 Graphics Card

The NVIDIA Quadro NVS 420 is a professional-grade multi-display graphics card designed to drive four independent monitors from a single PCI-Express x16 slot. Built around NVIDIA's CUDA architecture with 512MB of GDDR3 memory, it is purpose-built for business environments where desktop real estate is critical — financial trading desks, emergency dispatch centers, surveillance monitoring, and digital signage installations. The card outputs through a single VHDCI connector, which splits into four displays via the included VHDCI-to-quad-DVI-D breakout dongle at up to 1920x1200 per screen.

With a maximum power consumption of just 40W drawn entirely from the PCIe slot, the NVS 420 installs without supplementary power cables, making it compatible with compact and standard workstation chassis. NVIDIA's nView display management software provides advanced tools for organizing windows, managing taskbars across screens, and configuring display layouts — features that are essential in multi-monitor productivity setups. The card supports Shader Model 4.0, DirectX 10, and OpenGL 3.0, which is sufficient for 2D business applications but places it firmly outside the realm of modern 3D or gaming workloads.
