Alienware 17 - compatible screens

[XGIII]

Hi all, I'm french so, excuse me in advance for my english.

I've just bought a alienware 17 from my brother:

i7-4700MQ / 17,3 WLED HD+ (1600 x 900) / 8Go DDR3L 1600MHz (4Gox2) / 240W / NVIDIA GeForce GTX 880M with 8GB GDDR5

This was a good deal, but as said all over the web, the 900p screen is very bad quality (grainy and poor gamut).

I want to update the screen, I've searched around and find that from Dell there is only 2 others choices:

- 1920 x 1080 / 60 hz matte

or

- 1920 x 1080 / 120 hz 3D glossy

But on laptopscreen.com I've found other screen compatible with the AW 17:

Have you some informations about theses (gamut, feedback etc...)? IS all theses screen really compatible with the AW 17?

I'm interested by the 1920 x 1080 / 60 hz glossy (Item ID: 720863) . Because I want the optimus (which is disabled on the 120 hz) and I prefer glossy screen.

Thank you for your help
