Hello,
I want to know if I can plug my cables in my motherboard HDMI and Display Ports, but without using the onboard graphics, instead the GPU graphics. I have a small case and my GPU wouldn't fit in there, but it is a beautiful case! So, I am planning to buy a PCI-3 Male-to-Female and having my GPU in the upper level of the case and mount it in a bracket, but the problem is, I can't use the GPU ports. So instead I want to know if I can use the Mobo ones, is this even possible? Before I try, I would like to know more and I don't want to hear: "Buy yourself a bigger case!"
Thank you!
