I made two mistakes while connecting my HP OMEN 15-en1507na gaming laptop to Dell U2414H monitor via display-port.
The HP OMEN 15-en1507na gaming laptop has a mini display-port, and the Dell U2414H monitor has three display ports, a mini display-port and two normal display-ports. I am using the mini-display-port cable came with the Dell U2414H monitor.
The first mistake is I connected to the output display-port, the Dell U2414H monitor has two normal sized display-port, one is for input and another is for output.
The second mistake is you need to go to the Dell U2414H monitor's menu, and enable the display-port v1.2.
The problem has been solved since I fixed the above two mistakes.
