Hey, I just purchased a brand new Alienware AW2518H from Amazon.com 1080p, 1ms, 240hz & G-Sync. I watched many unboxing videos on Youtube for this specific model prior to actually purchasing this product. Now that I have it here in my home.. I noticed on the bottom left of the monitor on the bezel, there should be 2 stickers next to each other just like all the unboxing videos I saw. One that says Nvidia G-SYNC and the other that says 3D Vision. My monitor only says G-Sync on the bottom left. I don't have another sticker saying 3D Vision, How come? is this a cause for concern?
