    I just bought a 1080P display 1920x1080. 23 inch monitor.

    I have an early 2008 mbp with 2.5ghz core 2 duo, 4gb ram, and 512mb 8600gt. and when I close the lid to get the full resolution on my 1080p monitor, everything gets really laggy... Is it because my computer can't handle it? It's weird, when I do Dual Display, which operates at full resolution too..i think, it has no lag at all.. I was wondering why I'm experiencing lag?

    Thanks!

    That's strange because i use a 1080p 21.5 screen and i don't get any lag.
    whether i'm using the external only or both screen at the same time.

    i have the late 2008 mbp with 256mb graphics 9600m gt and i'm not even using the dedicated graphics. the integrated nvidia 9400m is handling it very well.

    so i don't think the reason is that your computer can't handle it.

    What are you using to connect the monitor to your computer?

    Same early 2008 MBP 4.1 (2.4Ghz ) I run in dual screen with a HP 24" @ 1920 x 1200 never experienced any lag. So the hardware is definitely capable, difference I am running Snow leopard 10.6.8

    connected via DVI, compare the machines temperature between the lid open & closed, there may be a difference if the CPU is getting too hot it will throttle down...

    I'm using a dvi-dvi to connect from comp to monitor.
    Hmm..yea after couple more days of using it, my computer is slower:( Is it because I run like 10 apps at the same time? well I do that without monitor and its fine.

    Your problem is consistent with many other Apple laptop users attempting to port their workspace onto an external display. I wonder if I may have a solution to your problem..

    Download & install Insomnia into your Applications folder.
    http://www.macupdate.com/app/mac/22211/insomniax

    Prior to executing the application ensure your laptop is already attached to the display in question.

    Startup & "Enable" Insomnia.

    At this time, if you haven't already, please adjust monitor settings so as to make your external display the primary workspace.
    (System Preferences -> Displays -> Arrangement -> Drag the menu bar to the desired display.)

    Decrease the laptop's brightness using the keyboard until the laptop display turns completely off/black.

    Shut the lid of your laptop.

    Work & play as you would :eek:

    I have the same computer with the 256mb 8600GT and a 1080p screen with no problems whatsoever. I'm sorry I can't be of any more help.
