hp pavilion power 580-023w DisplayPort port not working

[wzm61786]

Hi. I want to set up dual monitors for my desktop. I previously connected my monitor to the HDMI port on the top and it works perfectly. I know that the bottom two HDMI ports are not functioning. So I bought a displayport cable. I have tried the three DisplayPort on the top, right next to the HDMI port, and none of them works. My monitor would show "no DP signal from your device. " Does this desktop support DisplayPort? How can I set up dual monitors?

Thank you.

Does your monitor have DP input ? A direct DP-HDMI cable should work. Have you tried them all ?  I know DVI-HDMI works but had not tested DP to HDMI.

Hi BH,

Thank you for your response. I am trying with a DisplayPort to DisplayPort cable. My Monitor has DP input. I have tried to connect the monitor to a laptop using DP input and it works. So the monitor is good. I have tried all 3 DP inputs but none of them work. I don't have a DP-HDMI cable now. Maybe I can buy a DP-HDMI cable and try.
