Author	Topic
Clinton Full Member USA 700 Posts	Posted - 18 Jan 2003 : 15:23:31 anyone know of any way to get display spanning under 10.2 on an iMac G4 15"?, is there any software hack I could do? I am going to check out resexcellence.com right now, but I thought someone may know of a quick fix. anyway, TIA CCC Lieutennant Commander (Pronounced Leftennant) 68k Macs Rescued: 2 Pluses, a 512KE, a Classic II, a Q650, a Q660AV, and a MacII Contraband rescued: Power Computing PowerBase 200, a PM 8600/300, and a PM8500/180 Apple //s rescued: Apple //e

I found this link, but it looks like that the 17" might do it, but not the 15". http://www.xlr8yourmac.com/systems/ibook_dual_display_mods.html _______________________ Sgt.

Clinton Full Member USA 700 Posts	Posted - 18 Jan 2003 : 18:22:29 I know that you can, because I have seen it done. Someone installed OS9 on another G4 and then put the hdd into the iMac, and it spanned, though with a really crappy resolution, partially the macos was not installed with the iMac in mind. anyway, I am going to see what I can do, more suggestions welcomed CCC Lieutennant Commander (Pronounced Leftennant) 68k Macs Rescued: 2 Pluses, a 512KE, a Classic II, a Q650, a Q660AV, and a MacII Contraband rescued: Power Computing PowerBase 200, a PM 8600/300, and a PM8500/180 Apple //s rescued: Apple //e

tmtomh Junior Member USA 172 Posts	Posted - 19 Jan 2003 : 01:11:00 The iMac 15" cannot do monitor spanning, but the iMac 17" can. The reason is that the 17" model's graphics card is dual-head capable, whereas the 15" model's is not. End of story.

~Coxy Leader, Tactical Ops Unit Australia 2822 Posts	Posted - 19 Jan 2003 : 18:20:17 To recap: You don't need a "dual-GPU" card to do spanning. You do need a card capable of doing monitor spanning in order to get two screens. The GPU in the iMac 15" is not capable of doing spanning. It has a 2MX which is not the same as the dual-head capable 2MX in some early G4 towers. The GPU in the iMac 17" is capable of doing spanning, via a firmware hack. ~Coxy - Leader, Tactical Operations Unit Mayor of NuBus City v3.0
