For No signal try- Updating your Video drivers, and making sure it shows a connection on your laptop ( by going to propertys on desktop and then dysplay)
For format try- Updating and or turning down the screen resulotion becuase the size differs on screen even if you think it shouldnt.

You may need to use the S-video cable for video. Make sure video mirroring is disabled on the powerbook. Also, make the external monitor the primary display by dragging the menu bar to it in Displays preferences (Mac OS X) or the Monitors control panel (Mac OS 8 and 9).
