I have the 4k 60hz version of this laptop with a gtx1070 in it.I want to be able to play games at 144hz so i plan on getting an external monitor..namely the asus vg248qe
I read somewhere online that the external monitor will be capped to 60hz still, even if i connect it via mini dp to dp or mini dp to dvi., even if the laptops screen is turned off
Just wanting to know if thats true and if so, are there any ways by which i can game on an external 144hz monitor by any chance?

It has mini displayport, you will be fine with a 144hz monitor which can run 144fps if your laptop can run 144fps.
