Tough luck dude. If you have as good of a monitor as you do (1600x1200 suggests a decent monitor), you definitely want to use it to its maximal potential. Chances are, it won't happen unless you use a different operating system. OS X loves to limit everything a user does, Mac fanatic relish this limitation but experienced users get annoyed or fed up.Originally posted by dflett
Does anyone know why the 12" Powerbook is limited to a 75Hz refresh rate when driving an external monitor at 1600x1200?
As far as I can see, the Geforce 420 Go supports rates up to 100Hz at this resolution in other laptops. Is this a software limitation in OS X?
My monitor supports 85Hz. My eyes don't support 75Hz though. 1600x1200@85Hz is a pretty basic requirement IMO. Yes, the check box for recommended resolutions is unchecked. And no I do not want to go and buy a Cinema Display - I kinda like the IBM P96 I have at the moment.
Why you're asking people here to go around a limitation is beyond me though. Don't you know by now that the Mac fanatics on this web site are going to disregard your desire to keep your existing IBM monitor and force you to buy a Cinema Display? I mean come on, how can you be a loyal Apple user, doing everything Big Brother Jobs tells you to do and use something made by that evil corporation IBM (that collaborated with the Nazis in the 30's)?
I think there should be a new thread on this board called 'Discovered OS X limitations' .. you should post there and talk about what you just discovered. Then, when we discover all of OS X's limitations, we'll all celebrate and say that it's good that Apple limited us in the way that it did. Thank you big brother for protecting us from the extra 10 hz!
