Hi - I have a Mac and a PC that need to share a monitor. Problem is, when I introduce my cheap monitor switch box, the MDD Powermac ghosts horribly. In fact, my Mac ghosts horribly without the box if I use a monitor extension cable, even a really expensive one. I already use a DVI->VGA adapter and it seems that any additional level of separation causes ghosting. So, can anyone recommend a solution? Is there a well made monitor switch box which won't degrade the signal? Is there a way to boost the signal to stop the ghosting? Any advice would be greatly appreciated! Powermac dual 1ghz MDD, 10.3.5, ATI Radeon 9000, Hitachi VGA monitor.
