Hello,
My setup is as follows:
cpu: i5-3570k @ 3,4 Ghz
ram: 8 Gb kingston ddr3
psu 650 W
mobo: Asrock z77 Pro3
gpu: GTX 670 driver version: 301.42
os: windows 7 home premium
I have connected two monitors (samsung syncmaster 225bw and benq g2420HDB, both have dvi and vga inputs) to the gpu, one via vga cord+dvi-vga adaptor and one via dvi cord. Undependent on which one is connected with vga cord only the one connected with vga gets any picture. If I hot plug monitor with dvi the monitor wakes up but says no signal detected. In the case that only dvi cord is used i get no picture. I own only 1 dvi cord so I don't know what would happen if I plugged both in with dvi cords but most likely nothing.
The exactly same setup has been ran with old gpu (gtx 260) and everything works perfectly. I also tried plugging computer into a projector via HDMI cable. When pc was turned on the bios messages were normally shown on the screen and the "starting windows" or something similar message along with the windows logo forming there. After that the projector simply lost signal.
To make things more interesting everything was functioning perfectly the first time I turned pc on with the new gpu. Then next time I turned it on this happened. Tried restarting it and everything worked again fine. Now I've tried restarting the system multiple times but in vain.
This is my second GTX 670 because the first unit had the very same problem, it worked at the very beginning but after that I never got picture on both screens. I'm starting to believe that this is a software problem but between everything working and everything not working I haven't touched anything that affects the gpu.
I tried googling the problem but to no luck. I'm believing this has something to do with the gpu giving out only analog signal for some reason but I didn't find any way to affect the output method.
