Quad-display workstation card

The Dell K722J equips a small-form-factor workstation with an NVIDIA Quadro NVS 420 GPU and a PCI Express x16 interface. It targets professionals who need four independent digital outputs from a single low-profile slot. The card suits multi-monitor trading floors, control rooms or digital-signage PCs where expansion space is limited.

512 MB split across dual GPUs

Total video memory is 512 MB GDDR3, organised as 256 MB per GPU with a 64-bit bus each, combining to a 128-bit aggregate interface. This capacity handles four 30-inch panels at 2560 x 1600 for 2D business applications and legacy DirectX 10 or OpenGL 3.0 workloads. It runs out quickly with modern 3D rendering, heavy texture loads or GPU-compute tasks that demand larger frame buffers.

VHDCI connector and nView software

A single VHDCI port carries all four active display channels, so the bundle includes a breakout cable to four standard digital outputs. NVIDIA nView desktop-management software is supplied, letting IT teams clone or distribute display profiles across multiple machines without manual reconfiguration. No additional adapters or mounting brackets are mentioned in the specifications.

Preguntas sobre este artículo

Will this PCI Express x16 card fit and run in a legacy motherboard that only has a PCI Express x8 slot?

Yes — the Quadro NVS 420 uses a standard PCI Express x16 edge connector and will operate at x8 speed in an x8 slot without any extra configuration.

How can I verify that all four display channels are active after installing the drivers?

Open NVIDIA nView or Windows Display Settings; you should see four independent monitors each capable of 2560 x 1600 resolution.

Does the box include the VHDCI-to-four-DVI breakout cable needed for four monitors, or must I order it separately?

The card ships with the VHDCI breakout cable that splits into four DVI connectors; no separate cable purchase is required.
