Quad-display workstation card

The NVIDIA Quadro NVS 420 is a workstation graphics card built for multi-monitor business environments. It drives up to four displays from a single slot using a VHDCI connector. The card suits professionals who need a stable, validated platform for standard office applications across several screens. It is not for users who require 3D rendering acceleration or modern API support beyond DirectX 10.

512 MB GDDR3 frame buffer

The card provides 512 MB of GDDR3 memory across a 128-bit interface delivering 11.2 GB/s bandwidth. This capacity handles typical 2D productivity workloads and four 2560 x 1600 panels comfortably. It runs out quickly when applications demand larger textures, compute buffers or higher resolutions than the stated maximum. The 16 CUDA cores offer only minimal parallel processing headroom.

DirectX 10 and OpenGL 3.0 limits

The GPU supports Microsoft DirectX 10 and OpenGL 3.0, capping compatibility with current software that relies on newer feature levels. Driver updates for this architecture have ceased, so security patches and application fixes will not arrive. The VHDCI output requires a specific breakout cable or adapter to connect standard monitor cables. Buyers needing modern display protocols or ongoing driver support should consider alternative solutions.

Questions about this item

Will the NVS 420 work in a system that only has PCIe 2.0 slots?

The card uses a standard PCIe interface and will operate in PCIe 2.0 slots at the slot's native speed, providing the 11.2 GB/s memory bandwidth and 16 CUDA cores for your workloads.

How can I verify the NVS 420 is driving four displays at 2560 x 1600 after installation?

Connect up to four monitors via the VHDCI port using a breakout cable, then confirm each display reports 2560 x 1600 resolution in the OS display settings and that the NVIDIA control panel shows all four active.

Does the box include the VHDCI-to-DisplayPort breakout cable needed for four monitors?

The card ships with the NVS 420 graphics board only; a VHDCI breakout cable for four DisplayPort or DVI connections must be purchased separately.
