IMac :: Switch Off Internal Screen / Only Use An External Monitor?
Aug 15, 2008
On my 2008 24inch iMac the screen has a problem ( dead pixels ) and I will get it replaced in the future , in the mean time I have a very nice large external monitor connected to the iMac which I use ok, what I am looking for is a way at first when booting up , to be able to see both the iMac's screen and the external monitors screen, then some how shut off / make blank the iMacs screen only leaving the external monitor on ?

I have a MacBook Pro. I see that the new iMacs have a mini displayport input so that the 27" screen can be used with my MacBook Pro. I'm wondering how this works? Since there is obviously no button to push, how exactly do you switch between the iMac and the MacBook Pro displaying on-screen?
I'm looking for a external monitor that is compairable in brightness as my iMac's screen. The brand needs to be Samsung, and the look of the Samsung moniter I would prefer to look like the examples below. Why? Because I want it to match my TV. I'm also looking for a small monitor because the space I have is pretty small and I dont want to have to move my iMac and look at it at a angle. I currently have a Samsung SyncMaster 906BW with a 1440 x 900 60hz resolution and its VERY dull compared to my iMac and its at 100% brightness and 85% contrast. Here are some of the screens I'm looking at so far, would they be close to as bright as my iMac's screen?
im not 100% sure this is the right area to post this in but i have a 15 or so inch hp lcd monitor i wanted to use as a second screen for my imac via vga, so i was wondering if that kvm switch would alow me to have this setup
imac - (vga adapter) - Kvm switch - moniter and surround sound / xbox 360 - (vga adapter)
and the second part is... it says it is powered by bus does that mean it would be powered by the moniters or what?is that a bad idea? will it strain my imac or what.
Thing is I got hold of a 1ghz 17" iMac almost for free, it had a dead logicboard (I checked it with a voltage-meter), but I figured I could fix it and have a small hobby project-thingie going on. Well I just got a new logic board today, for a 1ghz 17" iMac g4.
Things is I only get a bright grey screen from my Mac when I boot. I've tried connecting it to a external display and that works fine. Everything is there.
I then reinstalled Tiger on it, with the computer connected to my external screen. And I still have the same problem. (I have now disconnected the ext. screen and is controlling the iMac from my MBP). So at least it isn't the installation.
So what is the problem? I can via an Apple Keyboard control the brightness on the blank screen, which would indicate that it does react to input of some degree.
I've read that if the inverter is dead or anything else is dead, you would get a rolling grey screen, flicker or something like that and not a steady bright grey. One thing I'm thinking is. What if somehow this logic board was for a 15" 1ghz imac g4? Can I check this?
I read that long thread about guys buying hi-res displays for their MBPs, and they had to replace some display profile? Could I maybe fix it with a different display profile-file?
I'm really confused by all this, and would appreciate any help I can get.
Model: PowerMac6,1 CPU-Type: PowerPC G4 (3.3)

the gfx chip is a GeforceMX4 with 32mb.
The display is a mode 9c27, manufacturer 610, serialnumber 00000, manufacture date: B84D7200.
Is there a tweak out there that will disable the internal display while using an external monitor WITHOUT having to first close the lid on my macbook because I just leave my macbook plugged in for weeks a couple feet away from my desk and it's become a hassle to first close the lid, then move my mouse, then open the lid for better ventilation. I just want to leave it open and disable the display!
I have seen people all over the internet saying that their MBP monitor would not turn on, but I have not seen my situation before. I used the computer a week ago (it's a work machine and I'm a part time intern) and both the external and internal monitor worked. I shut it down and when I came back the computer booted up to the external monitor but gave no video on the internal.
I shut down, removed the external monitor (connected by DVI cable) and rebooted. Nothing came up but when I connected the external again it worked fine. This had happened before, but when I shut down and rebooted without the cable connected it came back on immediately. I'm just hoping its not a bad graphics card or something that needs to go in for warranty.
I have a 27" i7. I have a 24" DVI Montior hooked up to it via MDP->DVI adaptor. When the 24" Monitor is on, everything is fine. When I turn the monitor off, the magic mouse tracking on the 27" screen stutters. I am not kidding - it took me ages to figure out that to fix I either need to turn the other monitor on OR disconnect the MDP->DVI adaptor.
we are trying to hook up our TV as a secondary monitor (for hulu, netflix, etc) but it defaults as the primary monitor. We would like to keep the imac as the primary monitor, and have the TV as a secondary, but cannot figure out how to do it! The only way we can get the imac back to primary status is if we use mirror mode. Once we take it off mirror mode, the TV becomes the primary monitor again, and there appears to be no way of switching it in OSX display preferences.
I've done similar hookups with my laptop, and the TV defaults as the secondary monitor. Why isn't this happening with our iMac? Any ideas?
Hoping someone can help - my imac (approx 15-18 months old , intel) won't start.
Last night on shutting down DPP (canon Digital image software) was hanging and system asked me if I wanted to force quit it...sadly I had switched off my bluetooth mouse and , as usually once mouse turned off switching it back on it never re connects - why did I buy the bletooth mouse and keyboard ?, so I could not confirm yes force quit - is there no way of selecting with keyboard like there is in windows ?
So I switched off at power switch. Tried to re switch on - grey screen came up, apple logo, the little timer circle but after a while timer circle stopped and nothing further happened.
have tried several more times and now don't even get timer.
I would like to transfer my imac's HD to an external HD. However, my current imac has a bad logic board – so the HD needs to pulled out in order to get any data. I am getting a new imac, but I don't know that I want to pull it all onto the new computer..
I have a 27" Imac and want to use an old 19" monitor as an external unit. I have it hooked up and turned on. Just the old wallpaper shows on it. There isn't an icon or anything diff on my iMac screen for it. How do I use the external? I realize this is pretty dumb, but I'm a newbie here and my Mac expert son is in NC....
I have my MBP hooked up to my TV. I was trying to get Front Row to run on my external monitor without having to move the Menu Bar over, but I quickly realized that was not going to be possible. My next idea was to play the videos straight from iTunes and just make them Full Screen. Having the videos playing over there works okay (my MBP screen is still normal), but as soon as I press Full Screen my MBP goes black. Is there any way to run full screen iTunes on my TV without losing functionality from my MBP?
The internal SuperDrive has a big demage and needs to get replaced by a new device. The replacement is to expensive. Therefore I bought an externalisier drive. But how can I deactivate the SuperDrive by Software?

I have a newer iMac 24" bought in 11/2007. I have the mini-dvi to vga converter and when I connect it to a external tv capable of 1024x768, the iMac freezes and does nothing. I disconnect and the screen turns blue and the flickers back on and everything works. I have made the connection then booted up, and I have tried every resolution all the way down to 640x480, same thing it just locks up the screen, but again as soon as I unplug the mini-dvi to vga cable from the iMac it flicks to a blue screen and everything comes back. I have reviewed dmesg nothing, and revieiw /var/log/messages. Is there any troubleshooting I can do. I am old school unix/linux guy just converted my family to Apple and would like to use the display on my tv to watch my iTunes movies.
I work on the macbook between 90min-2 hours throughout the day. At home, I hook up to a twenty-four inch monitor that I had calibrated through a Windows based system and complete my work. Now the files that I am working on are being processed through the macbook but viewed on the external monitor. I don't really care about the calibration of the macbook because the work that I am doing on it without the external monitor is really not color related i.e. removing scabs off of children, removing hair off of the face ect, but I need the final image to be accurate before it is sent off to the lab.
So, what do I need to do? Calibrate the macbook and the monitor or just the monitor and if just the monitor can anyone walk me through this? I know I could "search" but switching over from windows has been an experience and honestly, I am tired of "searching". Speaking of searching, I am still trying to figure out a way to sync my Dell x50v to the macbook, anyone? I know the x50v is old but it is the most solid piece of windows hardware I have ever owned and it still "just works".
I have a white MB (early 2008). I'm going to be getting an external monitor soon with a native resolution of 1920x1200 - the highest that the MB's Intel GMA X3100 will support. I know that I can open System Preferences > Display and then click the little menubar and drag it to the other monitor to make it the primary. Here is the thing: I want to just use my 24" monitor and not use the MB's screen with it (I have an external keyboard and mouse).
Should I... 1. Use the two displays as an extended desktop and then (leave the MacBook lid open) just turn the brightness on the MB all the way off so the screen is black (no back light)? or... 2. Just close the MacBook and use it in clam shell mode? I watch Hulu and YouTube a lot which causes the CPU load to increase and fans to spin up.... do I have to worry about over heating? I would be using the 24" monitor exclusively all the time and then take the MB when I go to class. Will this just ruin my MB pre-maturely?
I have the new macbook unibody, and use it from time to time to dsiplay things to an external montior, plasma, projector, etc. Using a mini-display adapter to a converter to get s-video was a challenge, but I figured it out. I have used this many times, as I am a DJ and need s-video out to connect to most devices.I was at an event saturday night, and the display on the external device (projector) kept displaying my desktop, NOT the external feed.
It was NOT set up for mirroring, as it seems like the displays were 'switched'. I had my desktop on the projector, and my external on my macbook pro monitor. I tried to fool around with arrangement and resolution, but to no avail. I understand that sometimes you have to drag your source to the right (of left) to get it to display on the external, and this was done, but it was still reversed.I know it was something simple to get the 2 switched back to the way it should be, but I could not figure it out. Any advice? None of my apple buds can figure this out.
How can I watch a movie on my external monitor in full screen and still work on my Macbook Pro? Every time I go back to work on my Macbook I lose the full screen viewing on my external monitor.
My 2006 mMcBook is dead and parted out. I still have the case and screen, but no HD, RAM, battery, or working logic board. How can I take the screen and make myself an external monitor out of it? I am presuming it's possible. I can solder a little and I love messing with parts from radio shack. So, has anyone heard of this? I tried googling it but couldn't find any search terms that brought me what I wanted.
Basically, I want to convert the video cable to DVI or even better, Display Port, and then figure out how to solder in a power source to just plug into a wall (since I'm assuming it'd be too big of a job to have it powered off of the FW800 or USB from the macbook pro). Is this possible? Since the computer is dead and gone, it won't hurt to experiment. Anyone have any links or guides to this?
I just recently (a month ago) bought my first MBP 13" unibody. When I connect it to my TV (Panasonic VIERA G10 Series TC-P46G10 46-Inch 1080p Plasma HDTV), the image is bigger than the screen, tried to switch resolutions with no success. The connection is minidisplay port to HDMI.
here we are with SnowLeopard 10.6.x and it still has no automatic shutting off laptop screen (Macbook Pro) when hooking up external monitor????Why do i have to close the lid, let my laptop go to sleep, wake it up, re-enter password, have my internet shut down and re-activate and all other processes just to shut down my MBP screen when hooked up to my cinema display???Hell even Windows Vista/ 7 does it automatically when i tested it via Bootcamp, requiring no closing of the lid or halting any processes or the internet.
I am attempting to use an external DVI monitor using the mini port port and the mini port DVI adapter sold by apple. However the screen display on the external monitor does not match the Mac book display. All I get is a color Mac opening screen with no icons.apparently there is more to getting an external monitor going then just plugging it in.
I have a 27" iMac and have connected a Philips 160e as a pallette monitor via a Mini Display Port to VGA adaptor. the iMac sees it but auto picks the wrong resolution 1280 x 1024 (stretched) instead of the Philips' 1366 x 768 @ 60Hz.
If I try to change the resolution the screen goes black which is symptomatic of using the wrong refresh rate, and of course I can make no further adjustments. esc does not get me out of the black screen.
What is worse the iMac seems to remember the wrong resolution/refresh rate after restarts.
I have tried Safe Mode (it stayed black) and booting off an external hard drive into another system (back into black if I change the display settings).
I have gone into System Preferences > Display > Color >unchecked 'Show profiles for this display only' > selected > Philips 160E in the list
It only contains .icc profile information, which I suppose is to be expected but is the only access I can find to any specific model data. The same display works fine with an older 24" iMac, using a different adaptor because of the different display port.
Somewhere OSX is storing the settings for the external monitor, I'd love to be able to trash it or change it back.

I just hooked up my macbook pro to an external monitor. Now, when I watch videos and what not, they will ONLY work in full screen. If I want to watch the video in a window, the sound will play but video does not. It may have something to do with Flash?
I have been having some problems with my Macbook Pro. I have a new BenQ screen connected to it via the Mini Display Port to VGA adapter from Apple. No matter what I do, I cant seem to be able to change the resolution to anything higher than 1280x1024, which is a pretty stupid resolution to have on a 27'' monitor. Sometimes when I plug it in, it gives me the option to change the resolution to 1920x1080.
But when I select it, the screen goes black and displays the message "No signal detected". Now, as it happens, I have a copy of windows installed on a partition of my hdd, and the screen works flawlessly on it. full HD with 75 Hertz. So that shows that it is not a hardware problem, it has to be a software problem. I tried everything, including reinstalling OS X, and deleting the "windowserver" files. no success.
