    Is there a way to turn off the MBP Display, while connected to an external display without being in clamshell mode?

    I'm running Lion, MBP 15" 2011.

    Would like to know too
    I think it has to be a monitor.

    Can you clMshell to a tv via hdmi?

    Why are you trying to avoid clamshell mode? Just curious.

    I'm running a 1440p external monitor, by simply turning the brightness down the MBP is still putting in graphical processing power to the MBP display.
    This way my Mission Control lags and I'm not too pleased with that kind of performance.

    It's Lion, I wasn't having performance issues with SL.
    I'm still trying to appreciate Mission Control.

    Not sure in Lion because I haven't done this in a while but I used to do this. Connect the display, close the MacBook Pro. Connect a keyboard, mouse, or even wake it up with the remote. It should wake on the external display but the Mac should still be closed. Open the Mac and the screen doesn't come on but the external display still is on. So technically you do have to close it to do this but you can open after.

    In Lion, when you close the lid the MBP doesn't go into sleep mode. It simply switches to the external display. When I open the lid, the display on the MBP comes back on.

    Don't connect the external display until the Mac is closed and in sleep mode, which may take up to thirty seconds like mine does. After sleeping then connect the display and wake up without opening. Try that, again maybe different in Lion.

    can't you just do the hot corner to put your display to sleep?

    Never tried it that way. Oh ya just remembered, it must be plugged into power. I'll see if I can find the Apple support article about it.

    Doing that will put both displays (MBP+external) to sleep. I do it all the time while downloading over the night.

    If you open the screen, the laptop screen will turn back on. Regardless of what method you use.

    I say, just run it in clamshell.

    That's what I do.

    Holy balls you guys I just realized I posted the wrong link. I was on my iPad last night and must have not pressed the copy right and I posted an old link. Sorry about that.

    Here is what I was trying to post: http://support.apple.com/kb/ht3131

    Note it says about halfway through because this is what I think your trying to do:

    I've been running in CS mode with my MBP (15" i5 mid 2010) and a 27" ACD. Since upgrading to Lion, the MBP seems to be running about 4 or 5 degrees hotter which worried me. Since reading a post here on the forum about slightly opening the lid of the MBP (about an inch or two) I can still run without powering both displays yet still allow a bit more heat to escape when running CPU intensive tasks...
    Thus far, I am quite happy with the results...temps running about where they were with SL...

    I believe the link you provided is talking about the clamshell mode.

    Thank you all for your time, for the time being the magnet "hack" is the only workaround.

    Ok I suck at copy and paste. So what I did was what the article said. Then after the external display is on and everything then open your laptop. The screen should not come on.

    This is what I meant to quote originally from the article:
