I figured id make this guide to help people running more than 1 card. or dual GPU's. As without these niffty devices tri quad or even 6-8 GPU's will not run on the same machine. here is how it is done. First get yourself a DVI to VGA adapter. Any will do. Adapter Next you will need resistors. The other guides on the net say to use between 68-70 ohm ones but any i find will do. The point of the resistor is to well...privide resistence so that Vista is fooled into thinking their is another monitor. Why do this? We are doing this because monitors are detected through current. when you plug a monitor in their is resistence on the line. if we mimic resistence we in essence mimic a monitor. you can get resistors at your local radioshack or micro center. we will need 3 per dongle so if you plan to make more than one buy accordingly. Resistor Now that we have our parts we need a diagram. you in essance will be putting the resistors in the last 3 holes of the first and second line on the right side of the vga (blue) end. Sound difficult? Its not but here is a pic. ok so now we start. Now some guides will make you take apart the connector etc. However this is unnessisary it fits fine you simply need to wiggle it if it gets caught. let us begin. First you have a standard VGA adapter. now on the VGA side pictured below start putting your resistors into place. Now keep in mind when you put them in keep the resistor itself (not the legs) center. this will avoid snapping or breaking and makes them easier to handle and insert. Also make sure that you bend the resistors so that they do not touch each other. I myself bend them to the right. the next onw slightely to the right. and finally the last one all the way to the left straight up. this will prevent them from touching. Example below Now that you get the idea. Continue with all 3 of the resistors when your done make sure the legs are relatively snug or at the very least dont fall out when upside down. your finished Dongle will look something like the one in the pic below. Now that your done disable SLI, plug it into your DVI port, extend the desktop and fold away good luck!
