If you saw smoke from the laptop DP side, then you can almost rest assured that the MB has been damaged in some way. The only way to know would be to take the laptop to a PC shop and let them analyze it. You can call Dell tech support but any damage caused will almost certainly be a charge service call even if you are under warranty.
Does the system even boot now or have any signs of life?
What kind of display cable? The only display cable that would work is an inexpensive HDMI cable available anywhere. It would directly connect from the HDMI port on the computer to the HDMI input port on the monitor-- no adapters. Your description of connecting the cable doesn't make sense. It's not worth trying to fix a 6 year old computer that was damaged so badly IMO. It could cost more than buying a new laptop.
I took it apart again and found the cable burnt on the tag from the motherboard side the pin slots are fine though, I guess I have to buy another OTP cable but I dont know how to order a reliable one that matches the specifications
While you can try that (and parts-people.com is a good source if you're in the US), that smoke did not spontaneously come from the cable itself. Realize that there's a very high probability that whatever shorted out, took out the mainboard.
