I just unhooked my PB out of target disc through my PPC Mac Mini (1.5ghz silent upgrade with 64mb vram) because the Powerbook is slightly faster by virtue of slightly more ram than the PPC's one gig. (The PB has 1.25gigs, also a 1.5ghz machine). But I cannot get the image on this older 17" LCD to be full screen! I was able to do it on a Apple 20" Cinema display. What gives? If I lower the resolution I can get it to fill the screen from my PB, but not at optimum res. There is like a two inch black bordder around the image!
