I have bought a second display which has HDMI, DisplayPort. My old monitor had HDMI and dvi-d. My motherboard only has 1 HDMI, dvi-d and DisplayPort. The DisplayPort cable that I have bought is either 1.3 or 1.4
I used HDMI for my old monitor and it works. When I connect the second display using DisplayPort it doesn't work. The system doesn't detect the monitor.
My system is using integrated graphics on intel core i5 4690k. My desktop environment is KDE 5.9

The system doesn't detect the monitor.
How did you establish that? Using the tools provided by KDE?
What is the output of xrandr ?
Was the monitor on and connected when you booted?
If it is detected by xrandr does it appear and disappear when you connect / disconnect the cable?

There are lots of other HDMI, but the output is too long.

You haven't answered ewaller's questions and you have deliberately truncated what I have asked for, which would contain information needed for people to try to help you.
If you want help you need to answer the questions asked by the people trying to help you. Don't forget to use code tags when posting the output of commands[1].
