    When I connect my late 2008 MBP to my new 24" Acer Monitor via the Mini DVI port I cant get full resolution on the monitor. The screen is only about 3/4 full and appears to be a LOWER resolution than the screen on the laptop. The monitor is connected Mini DVI to DVI via a Dual-Link cable. went into System Preferences, Displays, it shows the laptop resolution as 1440x900 and the Monitor resolution as 1920x1080. My MBP's 9600GT is capable of 2560x1600 resolution so that shouldn't be the problem. Maybe it's the Monitor driver but I couldn't find an OSX driver for it.

    Is there something I'm missing? Thanks

    Hi Snaky, check or un-check? It's currently checked, is that right? Also, I tried using a mini-Displayport VGA to VGA with the same results.

    UNcheck Mirror Displays

    If it's checked, the system will try to run the same resolution for both displays with less than desirable results.

    K, I'll try that (soon as I get home). Thanks for your help!

    I used an external keyboard and mouse, with the laptop on and closed I plugged in the monitor using the mini-Displayport DVI to DVI and awakened the laptop with the keyboard. The monitor came on in full 1920x1080! Cool and thanks.
