I don't know if this has been discussed before...
... Anyway, I have a LaCie
photon18blue LCD display, connected to a Power Mac G4 AGP (March 2000) with an ATI Rage 128 Pro (16 MB) video card.
The - very annoying! - problem is that the entire initial phase of the startup process isn't being diplayed on the monitor (which is connected through its DVI interface): it just keeps displaying "no signal", etc., until the Mac OS X progress bar ("Welcome to Mac OS X", etc., on the blue screen) appears, after which everything is normal. In Mac OS 9, everything works well, OTOH (the startup displays the "happy Mac", and so on)...
The real problem - besides missing the "happy Mac" part of the startup process - is that it's impossible to use the option key to select a startup disk ("no signal", indefinitely!) and to use the command-S/V, etc. shortcuts to perform special startups (still, "no signal" indefinitely!): is this the general behavior of DVI-connected LCDs under Mac OS X, or is it only a LaCie (alias NEC)-related issue? My iMac rev. B, OTOH, works without any problems (analog video)...
