I'd like to use a Tesla C2075's VGA (D-SUB) DVI output. I installed the latest Quadro driver (as suggested by the NVIDIA driver finder) on the 64-bit Windows 7, but it doesn't seem to be working. E.g. I can't use Aero, can't set a larger resolution than 1600x1200, etc.

Is it possible, that the card doesn't function as a graphics card? Or should I install some other drivers?

Update: the D-SUB output is actually a DVI-I output with the appropriate (passive) adapter.
The driver is obviously working, because OpenCL applications recognize the device, and they can use it.

Windows doesn't recognize the GPU, because it uses the Tesla Compute Cluster (TCC) driver model by default for maximal performance. However, Windows uses the Windows Display Driver Model (WDDM) to enable common graphic features.

The card can be switched to the WDDM driver model by the NVIDIA-SMI (System Management Interface) utility:

C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe -dm 1

You need to reboot after that.

Everything I can find about this card suggests that it is supposed to be capable of 3d hardware accelerated graphics (Aero, Direct3D, OpenGL, etc). However, are you sure you should be using the Quadro drivers? I am not confident that the Quadro drivers are the correct drivers for this GPU.
