SNOW LEOPARD - macbook pro with external monitor

My external monitor (Formac DVI) is giving me problems since snow leopard - if I start up and close the lid the external monitor goes black with thin grey lines. I have to keep the lid of the laptop open until start up is complete and the desktop appears on both monitors, then close the lid, let the comp go to sleep then wake with my bluetooth keyboard that's very annoying.
What are the chances this issue will be fixed soon?? I may go back to Leopard for a bit.....

I found the solution to this problem on another website, tried it and it worked!!!
10.6: Re-enable LCD font smoothing for some monitors
Mon, Aug 31 2009 at 7:30AM PDT • Submitted by astrosmash
There is a bug in Snow Leopard that disables LCD (sub-pixel) font smoothing on many third party LCD displays, including models from Dell, Samsung, LG, HP, EIZO, and Lenovo. Here are the details:
Snow Leopard introduces simplified Font Smoothing options under the Appearance pane in System Preferences. Prior to Snow Leopard, the available options were:
Automatic - Best for Main Display
Standard - Best for CRT
Light
Medium - Best for Flat Panel
Strong
In Snow Leopard, you can only choose between Automatic and Standard CRT. Since few people use CRTs these days, most users now have only one option: Automatic. The problem with the Automatic option is that OS X incorrectly detects many third party LCD monitors as CRTs, and consequently, disables LCD font smoothing.
You can force OS X to use LCD font smoothing on all displays with this Terminal command:
defaults -currentHost write -globalDomain AppleFontSmoothing -int 2
The number 2 here corresponds to Medium - Best for Flat Panel. You may also use 1 for light smoothing, and 3 for strong smoothing, as per the original OS X font smoothing options.

  • Using the MacBook Pro with external Monitor and Keyboard

    This may be a dumb question, but here it goes anyway:
    Can I use the MacBook Pro with an external monitor and a bluetooth keyboard and mouse without having it opened all of the time ?
    I am planning to buy a MacBook for my wife and most of the time she will be using it at her home office.
    I don't want her to use the computer opened all of the time when she is actually looking at the separate screen and using a separate keyboard. Having the laptop opened will only accumulate dust and reduce the lifetime of the built in screen.
    What I would actually need is a kind of "docking station", but Apple doesn't make that - I know.
    So can the MacBook at least be operated without the internal screen powered on while it is closed?
    Thanks for your help

  • MacBook Pro with external monitor and keyboard.

    Hello, everyone.
    I've tried to find the answer for this question but haven't found a clear answer with my Google search.
    My older Powerbook G4 will not allow me to work with an external monitor and keyboard with the screen in a closed position. I am about to purchase a new MacBook Pro and would like to be able to use it at home with a larger monitor and keyboard but with the lid closed and its built-in screen turned off. Can this be done ?
    How can a MacBook Pro be used (turned-on) with external monitor and keyboard while the lid is closed and the its screen is off ?
    Thank you in advance for your answers.
    Joseph

    Hi Niel,
    I have the same problem with my MacBook and I followed the instructions you posted. My issue is that when the computer wakes up after clicking the buttons on the keyboard it then quickly goes back to sleep. I can't seem to keep it awake when the lid is closed. I've been searching for an answer without any luck. Any idea how to solve this problem?
    Thanks!
    P.S. After I finished posting this message I figured out my problem. While fiddling with my computer and monitor, I inadvertently disconnected the power. After reconnecting the power, I was able to wake my computer and keep it awake. A note to other people having this issue: the computer must be connected to a power outlet to run in closed mode.

  • 17" MacBook Pro with external monitor issues under 10.6.4

    I have a 17" MacBook Pro 2.4ghz "connected" to a 23" Apple cinema display. For years now I've been able to just connect and wake from sleep with the MBP closed and start working. Ever since I've upgraded to 10.6.4 I have had problems getting my external monitor to switch on. I've had them both in the my local service centre and had them tested and they're both working fine individually. I though it may have been a power supply or Nvidia problem but they're fine. I can't get my monitor to wake either with the MBP closed or open. The sleep light will be lit but there is nothing on the monitor. I've zapped the PRAM, reset the SMC, run DiskWarrior and repaired permissions. Nothing works. I've even followed Apples guide to using them together under clam mode. Still no joy. So for now I'm stuck without being able to use my monitor which has been tested and is functioning properly. I'm wondering if anyone else has the same issues.

    that works, although the laptop isn't really close enough to my other monitor for that to make sense. I'd still like to know why it's acting this way.................... thanks for the feedback, though

  • Sleeping Macbook Pro with External Monitors: Bluetooh prevents and annoys.

    I have a 2007 Macbook Pro.
    Recently I decided to go all wireless and now have a bluetooth mouse and a bluetooth keyboard, as well as external monitors. Here's the problem.
    1. I like to keep my macbook pro closed and use the external monitors alone.
    2. That means that I need to have the "Allow bluetooth devices to wake this computer" option selected.
    3. My mouse (microsoft bluetooth laser mouse) will prevent the macbook pro from staying asleep. I don't know why... seems to happen even if there is no movement, maybe the mouse is searching for the macbook to see if it is still connected, but whatever.
    4. I would like the bluetooth KEYBOARD to wake up the macbook pro, but NOT the mouse.
    5. The bluetooth control panel does not allow me to customize -which- bluetooth devices can wake the laptop, it's an all-or-nothing scenario.
    This drives me crazy. I can either disable bluetooth waking, in which case I am forced to open the laptop in order to wake it up, but then I have the darn laptop OPEN with the laptop screen being used when I only want to use my external monitors, OR I can have bluetooth waking enables, in which case the macbook rarely sleeps for long.
    Any ideas? I do not want to switch to a USB mouse or keyboard, nor buy a different mouse or keyboard. The keyboard is an apple wireless bluetooth keyboard, the mouse is a high quality bluetooth Microsoft keyboard.
    I can't think of any reason why I shouldn't be able to just wake the laptop from the keyboard alone.... or for a way to stop the laptop from waking up randomly when bluetooth waking is enabled.
    Any ideas?

    Anyone?

  • Macbook pro with external monitor problem?

    i notice after turning everything on, using an external mouse and monitor, and then CLOSING the macbook pro, logic crashes alot. If I leave the macbook pro open, no crashes. anyone having this problem? no big deal, but it would be nice to be able to close the laptop if I'm using the external monitor and mouse in my main studio, and just using it as a laptop when I'm out on the road.
    thanks

  • Issues with "Higher performance" setting on Macbook Pro with external monitor

    Hi all,
    I rarely used the "Higher performance" setting in the Energy Saver pane of System Preferences.
    I use my MB connected with an external monitor, with its own screen closed. I tried to switch that setting on and the external monitor seems to repeatedly turn off and on. This strange behaviour vanishes if I open the MB's screen, using it in a double monitor configuration.
    Did anyone hear about some similar problem?
    p.s.: I don't know if this is the exact location for this thread, any suggestions is welcome

    It was set to 1080p, 1920x1080 did not show up as an option (even when holding the option key). 1080p should be equivlant. As as experiment I grabbed another monitor that was not being used. It is a 22 inch LG with a maximum display of 1920x1080, and its currently set to 1920x1080. The issue is a little different, was not detected as a TV this time, but the screen still looks blurry. There may be some improvement but not much.

    It can't be done. If your computer has an internal optical drive, working or not, that is the drive you must use. Only computers such as the Macbook Pro Retina/Macbook Air that have no internal optical drive can install Windows from an external drive.

    Just a final question about Sleep mode - does this have any negative effects on the life or performance of the laptop? I'm so used to Shutting down the laptop each day that I worry about Sleep mode having some sort of drain on the components or something.
    There are only two practical differences between Sleep and Shut Down:
    1. Sleep will wake instantly, so you don't have to wait for startup.
    2. Sleep will drain a new, fully charged battery after several days without being woken or plugged in. If you shut down, the battery charge lasts much longer. Obviously, if you only sleep it overnight, you'll still have plenty of battery left in the morning.
    Don't sleep it more frequently than necessary, though. Frequently turning the backlight and hard drive off and on can shorten their life. Just do what's reasonable. I usually leave mine awake until I have to transport it in a bag, along with sleeping it overnight. On battery, I'll sleep it more often to preserve battery.

  • Macbook Pro detects external monitor as TV

    Hi,
    I recently purchased a new MacBook Pro with Retina display. I plugged in an external monitor for the first time today and noticed that the screen looked blurry. I have seen on other forums that its a font smoothing issue but I ran that command in the terminal with no sucess. In my case its just not the font that is blurry, everything is blurry. I believe the problem is stemming from OS X detecting my external monitor as a television. Is there anything I can do to fix the issue or am I stuck waiting for Apple to update their video drivers. As a developer I like having as much screen space as possible but reading text on the secondary monitor is giving me a headache its so blurry.
    My external monitor is a 24 inch Samsung with a max resolution of 1920x1080. I am connecting it via the Apple mini display port to DVI adapter.

    It was set to 1080p, 1920x1080 did not show up as an option (even when holding the option key). 1080p should be equivlant. As as experiment I grabbed another monitor that was not being used. It is a 22 inch LG with a maximum display of 1920x1080, and its currently set to 1920x1080. The issue is a little different, was not detected as a TV this time, but the screen still looks blurry.

  • Macbook Pro and External Monitor flashing?

    I am using a Macbook Pro with an External Dell 1908fp 19" monitor via a Thunderbolt to DVI adaptor all fine.
    However the annoying niggle I have is that the monitor which seems fine, keeps flashing intermittently on and off randomly?!?
    Would anyone know why this is happening and if its the Mac's fault? I have the MBP open and the Monitor as the 2nd screen at 1440x900 which it seems to have defaulted to, and its very clear on both screens.
    Is my monitor on its way out? it seems ok, and is quite new (though it was 2nd hand a couple of years ago) or is this a known Apple issue?
    Thanks for any help

    The graphics card in the MBP supports resolutions far greater than that of the internal display, so any modern monitor will work fine - up to and including Apple's excellent (but pricey) Thunderbolt display and Cinema display.
    The MBP will detect the external display and set the image to the correct resolution automatically, or you can choose the resolution in System Preferences -> Displays, so you don't need to worry about a black border.
    Most modern monitors are 1080p and this works perfectly as an external display for a MBP.  You will need a mini-displayport to HDMI cable to connect the two.  If you get a monitor with built in speakers then that cable will also transfer audio.

  • Macbook Pro Retina External Monitor Blurry

    Just got a new macbook pro retina and got it home. After getting everything transferred over from my old toshiba I connected it to my 1 month old HP external monitor and the display is blurry. I have read on many sites that this is a common problem however I can not find a solution. I am hook up from HDMI to HDMI. O don't really want to go through trial and error of different adapter for the lightning port if that will not work. I have tried different HDMI cables to no success. Any Ideas?

    Hi AO1 James,
    If I understand correctly, the external monitor was blurry from the moment you plugged it into your MacBook Pro with Retina display. I would first check the resolution settings for the monitor with the "How do I select additional resolutions on my display?" section of the following article:
    Apple computers: Troubleshooting issues with video on internal or external displays
    If it remains blurry after selecting your monitors optimal resolution, I would use the steps under the "Reset the system" section of the article to help troubleshoot the issue.

  • Cannot install iTunes 10.7 on snow leopard MacBook Pro.

    I have received my new iPhone 5 two weeks ago but I am unable to use it since I cannot install iTunes 10.7. I have a MacBook Pro with Mac OS 10.6 (snow leopard) and 2GB RAM. I have been trying to install it and every time I get an error message saying that the disk could not be verified. I tried skipping verification and again it would allow me installing. Furthermore, I am trying to do my recommended software updates (including one about security) and my mac never succeeds. I am just wondering if that could be the problem.
    Any advice would be much appreciated!
    Thank you!

  • Macbook pro retina external monitor mouse skipping, lag problem

    When I plug my macbook pro retina (Lion) into a 24" monitor through the DVI adaptor, the cursor jumps erratically every ~10 seconds when being moved. Feels like a lag and is worse with more programs running. Does not depend on mouse or mouse surface. Trackpad does it too. Any ideas? Thanks in advance.

  • MacBook Pro with external display sometimes

    I want to use my MacBook Pro with my external display (Apple 23 inch Cinema) when I'm at my office, and to have Spaces set up and optimized for that. When I'm at home or on the road, I want Spaces set up differently, optimized for the MacBook Pro display only (no external display). Can I do this? Do I need to set up separate accounts on the MBP to do this, or can I do it some other way? Can you have sets, or multiple instances of Spaces? Otherwise, I want both options -- at work with MBP display plus Apple 23 inch Cinema or MBP display only -- to be able to access all of my files and software. The only real difference in the two setups would be the amount of screen real estate and where/how Spaces works within these different screen "landscapes."

    You will always have to use the power button to turn it on, and you'll have to open the display for that.
    Apple supports using the machine with its display closed, provided you follow the instructions in this article. As long as you do that, it shouldn't cause any harm. But I wouldn't recommend seeing how hot you can get the MBP with the display closed.
