Screen Upgrade Help - Anyone with a factory installed 1920x1080 Full HD Screen in a XPS L502X

Hello:

I have a Dell XPS 15 L502X 15.6 with a WXGA (1366x768) HD screen. When I bought it, at the DELL Web site, I had the option of choosing a factory installed Full HD 1920x1080 screen, but sadly I didn´t choose it. Since I work in Graphic Design now I see that I want to upgrade my screen to a better resolution.

What I have learn is that LG manufactures my current 15.6 with a WXGA (1366x768) HD screen. In fact this one is:

I have been looking for an upgrade to a 1920x1080 Full HD screen and what I have found after a long intense search is a compatible AUO B156HW01 V7 (Full HD 1920x1080) screen that can work in my laptop.

Even when many people says in different forums that this screen is descent in quality and features, it doesn´t have the quality of an LG or Samsung screen.

What I need to know is who manufactures the factory installed Full HD 1920 x 1080 Dell Screen in Dell XPS L502X,  to find it and then buy it.

So, please if anyone has a factory installed 1920x1080 Full HD Screen in a XPS L502X and can tell me who manufactures that screen, it will be very very nice and I will appreciate it a lot.

Or, if a DELL representative here can help me to find where to get it, will be nice too.

Thank you very much,

Eduardo RG
