Lenovo NVIDIA T400E 4GB GDDR6 4x mini-DisplayPort Low Profile Graphics Card

The Lenovo T400E stands apart from generic low-profile cards by packing NVIDIA's Turing architecture into a single-slot, bus-powered design that fits into the tightest workstations without sacrificing multi-display capability. Four native mini-DisplayPort 1.4 outputs drive up to four 5K displays simultaneously, making it a practical choice for financial trading desks, digital signage, and productivity-heavy environments where screen real estate matters more than raw gaming performance.

Highlights

• NVIDIA T400E GPU with 384 CUDA cores and 4GB GDDR6 memory
• Four mini-DisplayPort 1.4 connectors for up to four 5120x2880 @ 60Hz displays
• Low-profile, single-slot form factor with both low-profile and full-height brackets included
• Bus-powered with a 30W maximum power draw, no external power connectors needed
• Active fan cooling ensures stable operation in compact chassis
• Supports DirectX 12, OpenGL 4.6, Vulkan 1.2, and NVIDIA Mosaic multi-display technology

In daily use

Installation is straightforward: the card slides into a PCIe 3.0 x16 slot (electrical x8) and draws all necessary power from the motherboard. The included bracket options let you deploy it in both slim desktops and standard towers. Once connected, the four mini-DisplayPort outputs can be configured as independent displays or combined into a single large desktop using NVIDIA Mosaic. Hardware encoding and decoding for H.264 and H.265 via NVENC/NVDEC offloads video tasks from the CPU, which is useful for light content creation or video conferencing setups.
