[Solved] Video card shows in device mangager but does work

i'm trying to add a second monitor to a computer. i tried installing a pcie 1x nvidia and all i got was post beeps. so out of curriosity i yanked the card thinking that the card itself was bad. i tried an old 16x card that installed witouth a problem. but that card only has one vga outut and the onboard video is disabled. so i popped in the 1x card again along with the 16x. surprisingly it installed without a problem.

it shows up in device manager as working properly but when i plug a monitor into it... nothing. what am i doing wrong??

I don't think this setup will work. Its strange how the first card you put in didn't work straight off. But when you have both of them in, I think, windows will be using the second card as a physics card rather than a display output hence why there was no output to the screen

The post beeps could have been that the card was not seated properly, as it will do this if the card is not all the way in.

What are the names of the cards that you have?

Did you put the 1x card into the 16x slot? If it was in the 1x slot then i don't think it would have worked straight away.

Soo, try putting the 1x card in the 16x slot and see if that boots then add the 16x card in.
