The LCD on my XPS-L702X just recently cracked. I was looking for a replacement for it and came across the fact that there is a 3D and non-3D version of the 17.3" screen I need. I am almost positive that it is a non-3D screen that I need, but am not sure how to tell which one it is. How can I do so?

If need be, I can connect it to a television to check through windows, I just need to know how to do so.
