The product description of this LG LG UltraWide 49WQ95C-W monitor states that it has 4x USB 3.0. However, the 49WQ95X-W.AEU, which is actually described several times as being identical, only has 2 USB 3.0 ports. The product photos of both monitors also only show 2 USB ports on the right-hand side. Can someone clarify whether the ...C-W model has 2 or 4 USB 3.0 ports?
