I got a new workstation. Hp-z230 sff. And its motherboard got 3 displayports, but no vga no hdmi. Only 3 display ports. So i tried to use dp to vga converter thing. And it didn't work. Also i have installed gt710 graphic card. But I'm thinking of returning it. If i can get output using dp to vga converter then why should i waste money?. So is there any issue. The gpu is installed in pc. So do i need to remove it first to get the output to display?
