Here is what happens with the resultion, When you install LCPD FR, it detects what resolution you have (does something to where it installs the right resolution screen or something of that sort), And sets the comp screen to that resolution, Change it however, And you'll only see a part of the comp screen, Simply do this, Re install LCPDFR With the new Resolution, It should work, I had this happen when I was at like 2560by1980 or something of that sort, then I down scaled it to 1980/1280, and that happened to me, I just re installed and it worked, This might work, Or might be completely irrelevant, Idk, Just trying to help, Good luck
PS: I dont think the computer was meant to go to resultions that high.
