OK, loooooooong st0ry short... I have a GTX570 in one computer that I used a dvi-vga adapter, scrounged my scrap electronics, removed a 176.2ohm(meter) and inserted it to connect pin 1 to pin 6 while the computer was shut down. Booted it with secondary monitor hooked up as "extended desktop" in win7x64..."null plug was hooked where my primary display is usually hooked"...after starting miner and watching for a minute, turned the monitor off and removed it.
 Went to the bedroom, hooked the monitor to one of my other computers, using VNC to check and all is well so far. NOTE< there is NO monitor hooked up to the mining computer, just the null plug(one 176.2ohm resistor NOT 3)  176ohm was all i had vs 50-150 as called for. Now that this is done, I may just remove the dvi-vga adapter and install the resistor straight into the dvi plug on the appropiate pins.
 Will let ya know if anything goes wrong.
 I revived this thread as it is the first one I found when doing my initial search and it has all the pertinent questions, answers and both ways of doing it complete with links to pix and info. As I had a value higher than called for, I was nervous but it was all I had. Out in BFE on a COLD day and I'm a wheelchair test pilot who isn't going outta the hut today BUT determined to get it finished or pHuck it up, I just wanna surf lol.
 If it's a problem resurrecting this thread, tell me and I will scratch this.
