I've hooked up my ibook to my 37inch lcd display, and using screen spanning doc, I am able to get a resolution of 1286x768 (or something like that). The picture looks great, however I can choose between a few resolution/refresh settings. I can choose from 59 hertz or 74 hertz. Both display a picture on the tv, however using 59 cuts a few pixels of the top of the display (about half the menu bar). I'm only worried about damaging the tv somehow. Is that possible? What setting should I choose? My ibook seems to be handling everything ok though (good 'ol ibook).

thanks for any insight.

Yes it is possible to damage the TV with incorrect refresh rates, although rare.
Can't answer the question without knowing the make and model of the TV. It is the specifications of the TV that is the determing factor. If it has a vga connection, the owners manual should give you the recommended refresh rate.

Thanks, that helps a lot. I checked out the tv owners manual (probably should have done that in the first place), and it says for vga input and a resolution of 1280x768, I should be using a frequency of 59.87Hz.

Thanks for your help!!
