17 R1, LCD screen upgrade

Hello.

Can i ask for assistance with choosing screen for my alienware? Now i have 1080p 60Hz and i would like to get 1440p with 120Hz or if its not possible 1080p 120Hz.

I will provide my service tag on the screenshot and some info (BIOS A16), gpu: gtx 980. I know that i have to buy eDP cable and screen. Can anyone help me please?
