Alienware 15 R3 upgrading the screen alienware 15 r3

[maxk]

Hi guys,

I want to upgrade the screen of my alienware 15 r3. I currently got the 15,6 inch full hd ips Anti-Glare 300 nits Dispplay with gsync (391-BDEZ). The problem is because i have got gsync i cant switch to my other graphics card, which causes that i have only got 2 hours and 30 minutes battery life! my question is to which exact displays i could switch and if i could upgrade to a 4k or a 120hz or an oled screen. Furthermore i would like to know how i can figure out if i have got a 30 pin cable or something else and if i could simply buy a different cable and be able to use one of those sreens then.

Thanks for your help in advance, sincerely Max!
