MacBook Pro :: Use Computer In Closed Clam-shell (display Closed) Mode With An External Display?
Jun 4, 2012
I have an 13" MBP that I ordered new in April, 2012. It is running Lion. I have an external monitor that is capable of 1440x900 resolution. I have an external keyboard and trackpad hooked up, and I like to close my MBP up and stick it in a BookArc. I want to be able to have the internal display disabled and to have the MBP only allow me to put windows on the external display, so long as the lid is closed. I also want to be sure that I am taking advantage of the resolutions available on my external monitor, which are higher than those supported by the internal display (specifically 1440x900).
This doesn't seem to work because I either have to allow the MBP to continue to draw my desktop across both screens (internal and external), OR use the "mirror displays" mode, which restricts my resolution of my external monitor. This means I either forgoe the additional resolution benefits of my external monitor, or I end up with windows that fall off-the-cliff, so to speak, because they are drawn in the portion of the desktop that would be shown on my internal display (which is closed).
I've read the community support pages on using the MBP with an external monitor, most relevantly, this page. It simply recommends using the "mirror displays" option. However, this option, as I mentioned above, doesn't allow me to make use of the additional resolution, and my external display looks bad. how to keep the 13" MBP in closed clamshell position, with the internal display disabled, and use my external monitor at resolutions higher than those allowed by the 13" MBP but which are available to my external monitor when not in "mirror displays" mode?

I've been having problems with my mid 2009 2.53GHz MacBook Pro 15" not waking up from sleep after I open the clamshell (screen) back up. When I open the screen after letting it sit for a while, I can hear the HDD spinning up and the status light on the bottom of the MacBook turns off (like it normally does when the clamshell is opened), but the screen is black and there is absolutely no response in any key combinations or trackpad taps. I've been having this problem for about a month now and its getting pretty annoying. I've tried a total wipe of the disk and a fresh Lion install with a full TimeMachine restore, but I'm having absolutely no luck. The only thing that can bring the MBP back to life is a hard restart. Sometimes when I hard restart it, it comes back to life right where I let off (basically like when the battery loses all its juice and restores everything thats open), but most of the time, it starts up like a normal boot with no restore.

So I've recently connected my MacBook to an external display (a TV actually). Obviously, when I close the MacBook's screen the computer goes to sleep. How do I stop this from happening? I checked in 'help', it said that if I connected the monitor to the computer after closing the display, the computer would continue to run with the display closed. I've already connected it all though (running cables through cabinets, etc.) and I don't really want to undo all of that! Is there an easier way to set the computer to stay on (as opposed to entering sleep mode) when the display is closed?

When I have my macbook hooked up to external monitor it works great unitl I put it to sleep. Sometimes it kicks right up to the external monitor but the majority of the time it cant reconnect to the monitor. It just turns blue then off then blue likes its trying to figure out what to do eventually it says out of range. I then have to unplug the external monitor, wake up my mac with the screen open reconnect the monitor wait for it to pick up and then close it again and wah laaa it works.

I've just bought a Dell 2209WA. I'm struggling a little with colour profiles and monitor setting, not sure which is the best thing to do. I'll be working with some things that need to be printed out and some that are for web only. So I'm guessing I'll need to use different colour profiles depending on what I'm doing, is that right? Can anyone recommend some to me?1. Is it possible to close my macbook pro yet still have it working through my monitor? I have a wireless keyboard so it'd be preferable if I close close the mac and run the monitor from it.

Our display flickers on one side and has multicolored vertical bars running down the left side at best, or the whole screen greys out over the top of the graphical display, is physically no longer fully attached on that side near the hinge (you can press it down quite a bit after it has been closed), and the aluminum clamshell seems like it's warped. The bottom access panel has become no longer a smooth fit - it sticks up a few millimeters at the gap instead of being flat. We used to be able to hold the back left side and the screen would work, now we have been sitting it on a wooden structure with a back support and pushing it against that so we can see the screen for the past year or two. Now the flickering vertical bars are getting worse and the wooden support doesn't always work, and as an added bonus, the trackpad recently stopped working (it no longer 'clicks' and acts like it's constantly pressed down, so we have to use an external mouse with it). It's pretty frustrating because we've babied this thing (it's never been dropped or abused and has only left the house like twice, and one of those times was to take it in to see about this very problem!) and it seems like it's a manufacturing defect, but of course we never had AppleCare and this powerful expensive beast is now a desktop computer with a super hard to see screen. I've been told we need to pay $400 to get a whole new clamshell.

The external 19" LCD display does not work with the lid closed. However, it does work in full 1680x1050 when mirroring is turned off and the lid is open. When I turn mirroring on and the lid is open, the external display does not work at full 1680x1050, it shrinks the external view so the resolution is 1680x1050 but only displays 1280x800 worth of pixels.
Summary:
* lid closed, mirroring on, external display does not work (goes into "out of range" mode)
* lid closed, mirroring off, external display does not work (goes into "out of range" mode)
* lid open, mirroring on, external display will not do a full 1680x1050, instead will do 1280x800
* lid open, mirroring off, external display will do a full 1680x1050
A USB keyboard and mouse are attached. This exact setup worked flawlessly with a gen1 macbook pro out of the box.
How do I make the display work with the lid closed?

I have a 2009 unibody macbook pro. I have 42 in lcd tv. I have a minidisplay to vga adapter and a vga cable. When I try to connect the monitor to the mbp when the lid is open nothing is detected. I do not get any options to change to mirror mode or am able to change any settings regarding the monitor. I can change the resolution of the built in display only. Now for the twist. If I connect everything, do a restart and close the lid, as the computer boots up the external monitor works. Its the grey boot screen with the apple logo. But as soon as the computer begins to load the desktop, the monitor losses the signal. At first I thought it was going into sleep mode, so I hooked up a usb mouse to keep the computer awake. I tried the process again, and as soon as it goes to the desktop it losses the signal. So I don't think it is sleep mode. I downloaded the minidisplay prot firmware update, but because the screen is not detected when the lid is open I cant run it. When the lid is closed the computer either goes to sleep or doesn't send the desktop signal and I still cant run it. Nothing happens if I change between the video cards (9400 and 9600gm). Is it a resolution issue? Do the vga cables have a max resolution that is lower than 1900 x 1200?

I typed Mac Help about "to operate the portable computer with an external monitor attached and the display closed. When I close the display of my Mac Book or MacBookPro, the external monitor such as my 50" Plasma monitor or video projector would go black. I read the Help and it said and required the USB Mouse and Keyboard to close the Macbook display and put computer sleep. My question is will the Apple blue tooth or wireless keyboard and mice will work with out using the USB? Has any one try that? I am not sure if I should buy wired or wireless to operate this.

If you want to use the external display as the main display, and close the macbook pro is it possible that the macbook pro might overheat, or have negative impacts on the machine for keeping it closed while in use?

I have a MBP 13 hooked to an external display. When I shut the lid of the MBP, the external display turns off too, and I'd like the lid shut so the MBP doesn't take too much space on my desk.
How do I keep the external display on while the MBP's lid is shut?

I have a macbook pro and I want to be able to hook it up to my TV and close the laptop lid. Every time I close the lid, the TV goes black no matter what settings I change! I'm not sure if the laptop is going to sleep, or just disconnecting the TV as a display.
I've tried something called Caffeine, but it didn't do a thing.

When I leave my clam shelled computer alone for a while, it doesn't start the screen saver after 5 minutes like I set it to. Is this intentional on Apple's part? If so, is there a program I could download to make it work?

The display on my MacBook Pro turn on even though the lid is closed.
1.Sometimes The apple logo lights up and then turns of on itself when the lid is closed.
2. Various times have i closed the lid of my MacBook Pro and then re open it and the screen is still on and it has not entered the Login screen.
3. If i click the Sleep option on the apple menu it goes to sleep, so i close the lid but it eventually wakes up out of the blue.

How do you tell the MacBook Pro to output to the Apple Cinema Display when the lid is closed rather than go to sleep? I know you can use the ACD as a secondary screen OR as the only screen with the MBP lid closed. Is there a setting somewhere for this?

Has any one had any problems using an external display (Apple 24 inch LED is what I am using) with Bootcamp with an Apple laptop (recent MBP) in the closed lid position. I start Bootcamp & Windows, close the lid, but the display/computer won't restart once I plug in the peripherals.
