The "merged/xinerama" mode allows you to have one large frame-buffer (the virtual desktop) with the two heads showing two windows into this picture. In the simplest case this looks like xinerama, although it may (I don't have a G450) also allow you to move one or both heads around the virtual desktop, perhaps one screen showing everything, and the other one a zoomed in view of part of the picture. Without this feature, the driver pretends that the card has two completely separate framebuffers, and then Xinerama pretends that these separate framebuffers are one. Pretending twice reduces the flexibility and imposes restrictions. -- Dr. Andrew C.
