What this card does: It's not a standalone graphics card. It's an ADD2 (Advanced Digital Display) adapter designed for
Lenovo ThinkCentre desktops that have Intel integrated graphics with SDVO (Serial Digital Video Output) capability.
The motherboard outputs a digital video signal through the PCIe slot using Intel's SDVO protocol,
and this card converts it to a DVI-D port so you can connect a DVI monitor.
It was commonly used in Lenovo ThinkCentre M57, M58, A61, and similar models
from around 2007-2009 to add a DVI output when the motherboard only had VGA natively.
It won't work as a graphics card in a non-Lenovo system or in a system without SDVO support on the motherboard
it relies on the Intel integrated GPU to feed it the video signal through the PCIe slot.
