(OT): Question about the laptop's lcd screen

[jd1008]

Del Latitude E6501 (15.6")  matte screen, has a resolution of 1366x768.

Have been asked by a friend to replace it with a matte 15.6" with resolution
of 1920x1080.
I have no problem helping as I can open the screen and do the replacement.
Q: Would the higher resolution require a different cable to connect it
    to the motherboard?
Q: Would the graphics processor even be able to run it at 1920x1080?

The display model# my friend wants is
LG model LP156WF1 TP B1

I found this blog that says it is "doable" ;-)

Hoping that someone on the list has encountered or done this before.
