hey all, im new to this forum. i am having a problem with my monitor. i have an older g4, the video card just has the adc connection. i got a large flat screen that has a dvi connection. so naturally i got the dvi to adc adapter. well it still doesnt work. when i boot up the computer the monitor comes on only for a second then turns itself off, but the computer continues to boot up. i know the monitor works, i tried it on another computer. could it be my video card, or just drivers? no one seems to know. thanks for the help

You are going to need to give specs of your computer and the video card. That way we can help you in a more personal way. Granted i don't have a Mac right now but i have used many in the Graphic lab at school that are G4 400 mhz, some have had problems with the video card. Let us know exactly what model it is and what the other specs are and im sure some one can help.
 
Just a guess, but it's possible the computer is set to a refresh rate/resolution that the monitor doesn't support. Generally OSX will recognize what monitor you have and what it supports, but if that didn't work you'd be stuck with a blank screen.

If you have another monitor somewhere, try starting it up and setting the resolution to something really basic (640X480, 60Hz, or something equally low), then switching to the new monitor. Might work.

I had an issue like this on a new Dell server--wouldn't display an image on the LCD until I started it with a CRT, set the resolution, and then restarted. Ironically, it was the monitor it shipped with, too.

that's dell for you!

but it would help to know the model of the lcd. the above post ^ will probably be what you need...
