Before responding to OP, I tried to look up the specific laptop listed, but no video spec. I went to Dell website and tried to configure a Dell i7, and it asked for which video card -- but I had to consult NVIDIA website to see video res for the card -- and then returning to Dell site I still could NOT find the spec of it's monitor...and then my power failed to my home, including my cable and internet feed before finishing configuring a laptop ...it has been over 2 hrs. now.
Not for current laptops. Many new laptops are IPS with resolutions past 1920x1080. I recently bought another laptop, and saw that most manufacturers gave their specs for displays (15 and 17" displays now have options for 1080p or 3840x2160...and IPS seems to be the standard). HP Spectre x2 12" laptop is 3000x2000 IPS. Even integrated Intel graphics have supposed to have improved in performance (to be able to drive resolutions past 1080P)
Just got power back and tried again. Finished configuring the PC on the Dell website, I then picked the 15.6" size specified previously by OP, and I cannot find any video specification for the monitor!!!
 I had to COMPARE two Dell laptops in order to see any monitor specification! Although the video card is capable of far more resolution, I had to get this far to discover the inadequacy (for me) of a1920 x 1080 monitor and no option for higher res at that size....and I have no idea what size to get if I wanted higher res, other than to go thru changing the configuration of the laptop!
Let me repeat: the PC manufacturers MAKE IT HARD to find out video resolution of laptops until you are very deep into configuring the laptop! I cannot find a way to specify "I want/need more than 1920x1080, what brands/models of laptops can be purchased meeting or exceeding that criteria?"
