Ok so I just got one of those sweet Dell 20" widescreen LCDs. I am using a G4 powerbook 12". I'm having trouble taking advantage of it's higher resolution screen. I want to watch DVDs or use desktop applications on the larger screen and taking advantage of it's full resolution capability. Is that possible? When I separate the two displays, I seem to be able to use the higher resolution of the 20" widescreen, however if I "mirror" the two displays, i'm stuck using the lower resolution of my powerbook on the larger screen. I can't seem to run DVD player or move the dock over to the larger screen when I am in dual display mode. I basically want to use this new display and just forget about looking at my powerbook display when I am at home. And use it's full resolution. Is this even possible? Does my post make sense? Thanks a lot in advance!!! Help?!
