Hi guys, maybe this will help someone - i got myself a Dell S2721DGFA monitor. The screen can do HDMI 2K @ 144Hz and DP 1.4 2K @ 165Hz. I am using a USB type C to DP 1.4 cable (the one that Barlew provided link for) and the screen works at 2K @ 165Hz so i think the DP port of the laptop is 1.4 and not 1.2 as advertised.
