120hz instead 60hz

Ripley

Hi Folks

I use my V3 771g for videos and gaming - I've a 3740qm & GT750M with 4gb

Someone knows if I can use 120hz screen instead the 60hz ? Just cause I've found one with the same screwing  LTN173HT02-T02 - both are 40pins… thanks for participate and happy new year - Ripley
