I was considering getting a

I was considering getting a CUDA capable card and discovered that it didn't work if you took the screen off. Since I was going to put it on a normally headless machine I have deferred purchase. Apparently one can hot wire the socket or buy some contraption to kid the card into "seeing" a screen - not gone any further yet as it doesn't affect most of my projects.

Something for potential purchasers to bear in mind.

It is worth noting that not all CUDA cards are graphics cards. Nvidia Tesla C1060

Really? You mean there's no Remote Desktop possible under Windows for NVIDIA CUDA enabled cards? I really find this hard to believe. Most of my hosts are headless, two of them have CUDA enabled cards and I use VNC all day long under Linux to work on them, I really don't see why this should not work under Windows as well ....

I think adrianxw wanted to say that the graphics cards do not work if no monitor is plugged into the monitor-connector of the card.
I can't imagine that, what for does the graphics card need a DDC-signal at boot-time to activate his/her execution units?

It is possible, but you must not start BOINC when connected via RDP, because it uses its own drivers so that the CUDA device is not recognized (see this thread at the SETI boards).

As to needing a monitor (or a dummy plug), that and extending the desktop is sometimes needed for the recognition of multiple CUDA devices (again according to the CUDA forum at SETI, as I don't have a GPU myself).

You need to be careful in your use of terminology: this whole thread seems to be turning into a lesson in precision definition/semantics/pedantry.

Yes, you can use a remote desktop with CUDA, and I've heard VNC is a very good product which enables remote viewing of a desktop. But you can't use Remote Desktop (note capital letters), which is Microsoft's proprietary implementation of the generic principle, for the reasons that Gundolf states.

I will try to find the page that told me about it and post the link. It was an energy saving feature built into newer models.

Might be worth a try, but I suspect there might be the same problem. Even under Linux, Xvnc doesn't use the nvidia *display* driver, but CUDA is still usable. Go figure.
