I have a gts450 and gt520 installed and for some reason windows 7 is only showing the gt520 in device manager. Same thing in Nvidia Control panel. Now that said things start to get a bit weird. The monitors plugged into my gts450 are working which is odd because its not listed.

So I'm trying to figure out how to get my 3rd monitor hooked up to my gt520 vga port. It seams like I'm going to need to figure out how to get windows to recognize both of the cards and show them both in device manager.

Any help would be great.

Yes but I will double check.

It seams if windows is seeing the 520 and the video thats working is on the 450 they would both be powered but like I said I will double check.
