Can't change Refresh Rate

Question

Can't change Refresh Rate

To try to get my new Samsung LN-R268W monitor to show what's on the screen of my Power Book G4 (OS 10.4.5), the lady at Samsung Customer Support said I need to make sure my Refresh Rate is 60 hertz. System Preferences>Displays>Color LCD>Display had the Refresh Rate showing a greyed-out "n/a." Advice?

Powerbook G4, Mac OS X (10.4.5)

Is this before or after you've got the image on your Samsung? If it's before you've connected it, or used the F7 key to toggle to mirror/span mode, the only display you'll see under System Preferences is the built in display. And the refresh rate for that will be "n/a".

Most monitors will be auto-detected by OS X, and the refresh rate will be set without any input. My 20" widescreen Dell LCD automagically defaults to 60Hz.

At any rate, refresh rates for LCDs are kind of meaningless - they don't actually refresh like old CRT monitors do.

You're right. Today I learned from talking to somebody that I should turn on my monitor before I turn on my laptop. Page 53 of the Apple manual "Getting Started With Your Powerbook G4" suggested the opposite. However, if I had read page 53 and its reference to page 97 more carefully, I would have checked the "mirroring" box.
