Sony Vaio Screens

[Godspeed27]

I replaced the screen and hard drive on a Sony Vaio PCG-F50A, only in Japan, I think. I replaced it with a similar but not the same screen from another Sony Vaio. It works but the image on the screen is only 2/3 of what it should be and then mirrors itself underneath. Should I try to install bios or is this b/c the screen is just different than what is supposed to be on there.
