A question for the gurus out there. Under W10, can one crunch on an NVIDIA GPU which is NOT attached to a monitor - the monitor being attached to an internal graphic card?

I remember something was mentioned about a dongle. Is this a thing?

Thanks!

No clue on Wins 10 as I stay away from it. But on Win 7 you can. The dummy plug I use just to keep the screen resolution at my preference instead of max size when I remote into the machine. Just a FYI. Amazon sells dummy dongles.

Yes - I got mine through Amazon, too. Search "dummy plug headless" does the trick. People used to solder them themselves in VGA days, but you can now get DVI and HDMI up to (at least) 4K resolution - I wouldn't try making one of those.

I believe Toni's question was not about using a dongle for remoting into a headless server, but rather will BOINC crunch on a gpu that does not have a monitor or dongle connected.

Yes it can.

I'm running several of my GPUs headless under Win10. Works without issue.

Though not always for Intel GPUs.

The Monitor can be connected to internal GPU, the Nvidia GPU does NOT need to be primary GPU (as long as motherboard BIOS supports this config) nor does it need a dongle to crunch.

The only card I've seen picky about having something attached has been my RX 580. NV and Intel are fine w/o anything attached. Sometimes a 2nd 'monitor' can be setup within windows w/o having a physical monitor actually attached to satisfy the GPU.
