MacBook Pro 17" Resolution

I'm borrowing a friend's MBP 17" - it's the first Intel-based 2.16Ghz model
the specs show a native resolution of 1680x1050 (http://support.apple.com/kb/SP33), however his is only displaying at 1440x900 - the same as my 15"!

he bought the laptop used with OS X 10.5 installed, so i don't know if there are any incompatibilities there?

anyone know why the display settings list doesn't contain a higher available resolution?

 

oooookaaaaaay...

anyone own a 17" 2.16Ghz with 10.5 installed????

 

what do you mean by that? the spec link i listed above makes no mention of a lower native resolution. i've even googled, but haven't come up with anything.

obviously the graphics card supports this resolution. plus why would they release a 17" laptop with the same resolution as the 15"? isn't the whole idea more screen real estate?

then again, i'm still somewhat of a mac newbie, as is the owner of this laptop.

anyone else?

 

haha, yeah, i'm quite sure it's a macbook pro, 17" 2.16Ghz, ATI Radeon X1600 256MB.

and 1440x900 is the highest resolution listed in the listbox found by going to System Preferences > Displays and clicking on the Display tab.

 

hmmm, looks like the ati radeon x1600 isn't fully supported on 10.5... or at least, it's not in the drivers/updates list: http://ati.amd.com/support/driver.html
