Need some help with second display on my powerbook

Once you hook up the monitor to your powerbook and it does the flicker thing make sure you hit the "source" button on the front of the monitor. It is the one on the far right I believe. That gateway monitor tends to default to the analog input. I used that same set-up for awhile until I finally gave in and bought a 23" HD apple display. Hope this helps.

 

i am having the same problem with the same monitor. I dont think there is a source button like youre talking about....just a power button and two brightness buttons

 

by flicker, you mean, it flickers continuously? or just for a few seconds and you get a "black" screen without any current?

with my powerbook, if i plug in an external monitor, i automatically get the spanning mode.

 

I don't have to do anything. It automatically goes to spanning mode, although odd things have happened from time to time where I have had to detect display through system prefs.

This is probably a stretch, but does your diplay have multiple inputs? If you are plugged into the DVI input you may have to select the DVI input on the display for anything to show. My LCD works like this, although there is no flicker when the wrong input is chosen to display.

You definitely don't need any sort of converter/adapter unit as your PB has DVI-out and your monitor has a DVI input.

 

i know when i plug the gateway LCD into the PB, i get a blue screen on the PB for a few seconds (i guess that means its recognizing the LCD) but then the LCD just sits with a black screen, as if it were hibernating.
