Looking into acquiring an external 144Hz FHD (1920 x 1080) monitor for my XPS 15 9510.

I was wondering if this machine is able to output and utilize the full potential of the monitor mentioned above? If so, what are some information and accessories I should I know for this process to happen? Thanks in advance.
