Dummy plugs in win7?

[enmaku]

I've been mining on a few PCs around the house, but so far every GPU I've mined on actually has a monitor plugged into it. I just got a third video card for my quad-PCIe motherboard but don't have a third monitor. Are dummy plugs required on Win7 with the latest CCC/OpenCL/Drivers? They seem easy enough to build, I just want to know if I should plan for a trip to Radio Shack before my new card arrives.

Thanks!

Yeah, that's the same guide I was looking at and it all seems simple enough. I guess I'll make my Radio Shack trip on the way home then.

You can also do it with one 75 ohm resistor

Very nice! Still I think I'd rather whip together a dummy plug than insert leads directly into my card. At least if I break a wire off in the dummy plug it's only a $5 adapter I've ruined
