First off I am new to os x..
But tech savvy..

Thanks in advance for reading!

In system preferences in Display it only show 1024x786 but my monitor supports 1440x900. Where can i find a driver? Or what this the fix? Ive been googling all day.

I read that the 10.5.8 update fixes this but when I updated it hung on the gray apple screen with the turning circle icon. Does the update just take awhile? like more than 15 minutes? or is it hanging there cuz i updated through software update?

Computer Specs:
iatkos v7 - 10.5.7
lenovo x60 tablet
1.9 Ghz Intel centrino duo processor
Intel graphics accelerator

really, much appreciated.
