Reaching 120 Hz refresh rate on my laptop?

Hello there.

First of all, this is my spec' for my laptop that I think related to this topic (Not that detailed but here I go)

CPU: Intel i7 2670QM 2.20 Ghz
RAM: 8GB total (4GB x2)
GPU: Nvidia GeForce 540M Optimus 2GB Memory.
OS: Win 7 Professional Home x64
Laptop model: DELL XPS 15 L502X

Practically I saw a HDMI port on my laptop so
and somehow I was thinking of using an external monitor, a good monitor with at least 2ms respond time and 120Hz refresh rate, instead of using this laptop's monitor which caps my RR at 60Hz

As usual, I'm of course trying to increase my FPS for games (indirectly). There's always time where my FPS would only range from 55 - 70 and I find it's quite slow.. (Given that the game actually let me reach 80 on certain occasion)

Given the game is only 2.5D (Not even 3D, more like 2D).. I'm sure having 55-70 is a bit normal.. I'm plainly just trying to reach at least 80 during my play, 80 - 120 works fine

Also, given that the monitor is quite costy (300 - 600 AUD), I guess it's better to ask the community.

Does it actually possible to raise my refresh rate from 60Hz into 120Hz or a bit lower but somewhere more than 60 - 75 Hz with my laptop&the spec.

- Side question, does monitors normally come with one cable? (Like only HDMI or DVI) or do they come with both?

Thanks for the help, your answers are appreciated!

HDMI is not capable of 120hz currently, though the next standard to hit the market is supposed to include it, but we aren't there yet. It will allow up to 75hz at 720p, but only 60hz at 1080p.

As far as I'm aware, there is nothing you can do to your existing built in laptop screen to increase the hz.

If I may know, what's capable of 120 hz currently?

So, no matter what, it's not possible huh.. I guess I'll have to wait and save for pc that I might build..

Thanks for the reply!

You cant really notice the difference 120 hz vs 60 hz. Also getting a new monitor won't increase you fps in gaming if thats what you are asking. 300-600 is a lot to spend for a monitor, you should just save the money for that build you might be getting.

You can notice a difference, but I notice it more with my stomach than my eyes. At 60hz I get motion sickness with FPS to match (v-sync), but at 120hz I do not (with fps over 80). You also see it when spinning around fast.

Dual link DVI-D and Displayport connections can get you 120hz, but you don't have that as an option, so don't worry about it.

If you can't notice the difference in motion between a standart 60hz lcd and a good 120hz one then you're blind.
