I have a Dell Latitude e5400 and i am replacing the screen but i cannot find the exact same screen without paying more than the laptop is worth. The one i took out is a Model# B141ew05 v.3 . I found a reasonably priced screen but it is v.5 will it make a difference or do i need the exact same one ? Also can someone please explain the numbers and letters to me. I know the B is a AU Optronics manufacturer and the 141 is the screen size but the ew05 v.3 i am curious about . Thanx for the help
