Zwei externe Monitore an MBP 13" 2012?

Ist es möglich zwei externe Monitore an ein MBP 13" 2012 anzuschließen?

Try going in System Preferences / Energy Saver and resetting to default.
Might also want to ditch Chrome and delete it for awhile; it is generating too many warnings.

  • Can't sign in on external monitor with MBP after Yosemite upgrade

    After Yosemite upgrade, when I turn on my MBP, I can't sign in using external monitor with MBP, always could before Yosemite.  Blurred image of my wallpaper shows on monitor, can move arrow on external screen but sign-in only shows up on my computer screen, with no arrow.  Since there is no arrow on the computer screen, and no sign in box on the external monitor, I have to unplug the external video to sign in on the computer, then plug in the monitor again.  Any ideas?

    NOWEK,
    Thanks for this suggestion, but so far no joy. I have zapped the PRAM, jammed the Frabitz and smashed the Gafrogsnicker, all to no avail. When the MBP restarts I get a blurred image (extreme "vibrancy") on the external monitor, but no images of the login accounts to choose from or the other options. However, on the MBP screen I get all that. The keyboard and mouse respond, but just doesn't display on the external monitor. This is of interest to me because I have the MBP down in a credenza with other related gear and the external monitor and keyboard up on my desk. It's true I don't have to do this often, but still, it just started this aggravation with Yosemite. Thanks for trying to help.

  • Using a PC laptop as external monitor for MBP

    Hi!
    I just purchased my first mac. I want to have a dual monitor setup so I can have a bigger workspace when I design graphics on my Macbook Pro.
    Can I use my other laptop, which is a Toshiba, as an external monitor? The guy at Radioshack was worried that both the MBP and the PC laptop would try to send output signals and end up frying both video cards.
    Thanks!

    ScreenRecycler works very well. Contrary to what others have said on these boards, it is possible to use a second laptop as an external display.

    You will need a fast network connection between the two machines. Gigabit ethernet would be best, but performance is very good with 100 Mb. I wouldn't try using wireless to connect the machines - too much lag.

  • External monitor blurry image rMBP 2012

    Hey guys!
    I have 2012 rMPB which works perfectly and i am connecting it to my 22" Benq monitor via MiniDisplayPort to VGA connector (monitor only has VGA).
    Image on the external monitor is really bad, it looks blurry, not sharp enough and brightness is very low.I tried calibrating it, no luck
    Monitor is working properly (tested on Win laptop) and resolution is set to native FullHD so i dont know what could be the problem...
    Any suggestions?

    Hi,
    I'm facing the same problem. The fonts on an external monitor are very blurry. Graphics and icons are displayed crystal sharp. I can rule out any issue with the monitor or cable (mini DisplayPort to DVI) whatsoever, because if I run Ubuntu in VirtualBox, then within the VM the fonts are displayed sharp. Also no font issues on the notebook display itself.
    So it all comes down to a font issue on external displays, as can be read in several forums. The font smoothing tweaks didn't show an effect.
    Macbook Air 13" mid-2012
    OS X 10.8.2 Mountain Lion (10.8 pre-installed)
    External Display: Benq G2222HDL connected via miniDisplayPort to DVI Adapter on the Thunderbolt connection
    Can anyone reproduce the correct font display in a virtual machine?
    Thanks,

  • What is the best solution/product to connect 2 external monitors to MBP ?

    Hi!
    1. Can I use my MBP 13" (2011 i5) monitor as secondary when I connect an external one?
    2. Which solution is the best to connect 2 external monitors to my MBP 13 2011 i5 ?
    Thanks!

    Yes. You can mirror or extend as been so for many years.
     2. Which solution is the best to connect 2 external monitors to my MBP 13 2011 i5 ?
    None, the graphics card is poor integrated graphics and it can barely drive one external monitor, much less two.
    If you wanted two external monitors the machine to get is the Mac Pro.

  • External Monitor on MBP (Invalid format error)

    I searched the forums and couldn't find a similar issue so here goes. I have a late 2008 MBP with Snow Leopard connected to a Vizio(MODEL#VM230XVT)LCD 1080P HDTV. I'm trying to use this in "closed lid" mode and using Apple Bluetooth mouse/KB. Because, I didn't want to buy another HDMI cable I currently have it connected via VGA with Apple adapter (DVI>VGA) and a separate audio cable running to TV I have the Bluetooth settings set to wake the device. when I shut the lid the screen goes black either states "No Signal" or "Invalid Format". I have to disconnect the external monitor in order to see the MBP screen again I have tried using several different types of Resolution without success. I notice under the resolution settings it has a "useable screen size underneath it with certain dimensions" so if I set my MBP to max resolution I believe 1400x900 (guesstimate) and set my HDTV to 1920x1080 I think underneath the resolution box I get the "useable screen dimensions which are usually the laptops screen dimension" not sure if this plays apart in anything just wanted to mention it. The TV will display if I leave the lid open on the MBP and have a resolution that exceeds 1024x768 so I'm not sure why it won't display with lid closed as well. Any suggestions would be appreciated.

    Then I'd…
    1) Try reinstalling WoW and try to keep as few preference/game files as you can. Granted you need to keep your character and game play files etc etc so just backup the lot and restore as required.
    2) Contact Blizzard and check their forums and see if they know anything about this.

  • How to display 2560x1080 on external monitor from MBP or MBA?

    Is there any way to make MBP 17 (Intel HD and nVidia GT graphics, SnowLeo) or MBA 13 (Mountain Lion) display 2560x1080 on external monitor (LG 29" ultrawide)? My MacPro with RadeonX1900 card (10.5.8) does it perfectly but I cannot find a way to get the laptops to do it. Tried res. switching apps, still no good. Thanks.

    It worked perfect for me. Maybe settings should be different for your laptops. In my case I'm using a MBP 15" with a GeForce 330M.
    The monitor I have is the LG 29EA93 (21:9) @ 2560 x 1080.
    Make sure you have exactly same values in Switch Res X. Special attention to "Scan rate".
    You can see in the capture below that it's working
    and, just in case, here you have the settings that worked for me
    It might be also different for each video card...
    Greetings!!

  • External Monitor causes MBP to turn off

    I got my MBP back in April. I also got a Dell 2005FPW external monitor that I hook up to my MBP when I am at my desk. My MacBook Pro gets really, really hot, just like others and apparently that is ok. I guess it is no longer a "laptop" because it is too hot for a lap. Anyway, aside from being uncomfortable, the heat usually does not cause problems. However, I have found that when I plug in my external monitor and have both screens going and have my processors maxed with some video applications my MBP will just turn off. Not sleep, or anything else, it will simply turn off. This is while it is plugged into the power so it is not a battery problem. How can I get my MBP to stop turning off, aside from not plugging it into my external monitor and running intense applications?
    Thanks,
    Jonathan

    Do the random shutdowns happen when you don't have your MBP
    connected to the external display?
    I have tried to duplicate the random shutdowns without the monitor attached, but to my touch, it feels as though the MBP does not get nearly as hot as it does with the external display attached.
    Do the shutdowns happen with less intensive processor
    tasks?
    No, it is usually when I have multiple programs open and both cpu's are near their peak.
    Are you using the display cable that came with the Dell
    display? Is the cable firmly seated in the display and the
    MBP?
    Yes, I am using the cable that came with the Dell display. Yes, firmly seated.
    Have you installed any third party software that uses
    kernel extensions (like a temperature monitoring program)?
    No, but I have downloaded TechToolDeluxe, I have just not run it yet. Should I?
    Do you hear the fans come on at any time before it shuts
    down?
    Not that I noticed but I was not really paying attention.
    A little more background information. I originally found this problem because I would have my MBP at my desk at home, hooked up to the power supply, external keyboard/speakers/monitor. I would start a video processing application running on a long task and go to bed. I would come back and the MBP would be off. I would turn it back on and the task I had it working on would be only partially completed.
    So I took it to work where I sit in an air conditioned office and have it on a glass-top desk. I tried to hammer it with tons of programs being open and video processing applications. The CPU's would run on max for hours and the MBP would get plenty hot but would not shut donw.
    It is only recently that I realized that the shutdowns happened only when connected to the external monitor. So I thought that perhaps the video card for the external port was producing just enough extra heat to get the MBP to shut down. To test this I ran the same video processing application that I usually run over night, only this time I left the external monitor detached. No shut down.
    Does the TechToolDeluxe program measure heat? That would help to quantify the heat levels.

  • External monitor with MBP. Non Apple monitor

    Am about to purchase a new MBP and I believe I will be able to get a new Dell 24" monitor.
    question, I have read that many monitors periodically require Firmware upgrade to work at their best.
    For instance, there is a new update for the line of Dell monitors in which I am interested,. However, the firmware update (software) is only available in a ".exe" version which is Windows software,.
    How do Mac folks upgrade their non -Apple monitors? I know plenty of y'all use third party monitors.
    any tips on installing/using a third party monitor with MacBookPro will be will be appreciated, as well.

    your reply is very reassuring- I am going to purchase an external monitor for both my new MBPro and the current Macbook which I own.
    Lots of posts here assure me that using third party monitors can be done without too much hassled. (I just can't afford the Apple monitors otherwise would purchase)
    My concern came from stuff I have read (CNET) and In Dell forums where Dell concedes that the line of monitors I am considering DO have some difficulty with "banding" (Dell was getting numerous troubleshooting calls and exchanging monitors).Apparently the new Firmware, just published, fixes the problem.
    I guess I can run the firmware once I have Windows running (Parallels) in my new MacBookPro. And maybe companies will start releasing their software in Mac-usable format now that so many more Macs (especially laptops) are being sold.
    Thank

  • External monitor for MBP retina 13 inch

    hi,
    i am an undergrad student and i bought mbp retina 13 inch in dec'13.
    now i want to use an external monitor for my work which is mostly coding and stuff .i dont know much about display monitors and their ports or pins : vga ,dvi or displayport.
    please help me with suggestions as which one is better monitor to have and some info about the ports or pins is also needed ( as i already have apple's mini displayport to vga adapter ,which i bought to connect my mac to projector although its done rarely )
    i do have a budget for this , its about $ 150 to 200 .
    thanks.

    Here's - http://www.amazon.com/ViewSonic-VA2446M-LED-24-Inch-LED-Lit-Speakers/dp/B00D601U C8/ref=sr_1_1?ie=UTF8&qid=1393758755&sr=8-1&keywords=24+inch+lcd+computer+monito r - a 24" ViewSonic monitor with DVI input (much better than VGA). It's within your budget and you could still afford a good adapter for it (such as this one from Monoprice).
    Good luck,

  • External monitor scrambled MBP

    Hi,
    I have a macbook pro 2011 model. Lion OSX 10.7.4   
    I am using with an external LG monitor using apple VGA adaptor.  About 3 times out of 5 when I put to sleep upon waking my external monitor is completely scambled and MBP is frozen.  I have to hold the power button to shutdown then restart which fixes it.  This only happens with external monitor plugged in.
    Any idea whats going on here and how to fix it?

    .. might have a connector shorting-out problem.. check to see if any pins are touching. If so, then gently separate them.. with your computer powered off btw.

  • External monitor on mbp exits sleep

    Hi,
    when I sleep my mbp screen and external monitor both sleep.  When I come back to the room later the external monitor is powered on, this occurs daily.
    Does anybody know why this would occur and do you have any suggestions on how to prevent it turning itself on?
    thank you!

  • Trying to use external monitor on MBP

    Hi,
    I've hooked my Macbook Pro 15" to an external Dell monitor, keyboard and mouse and everything seems to be working fine - I can put the laptop to 'sleep', then wake it up via the external keyboard and then use the external monitor as the main monitor with the laptop screen 'asleep'.
    All working fine, but only when I'm using the power adapter. If I try and run from just the battery the laptop keeps going back to sleep. It 'wakes', but after a couple of seconds goes back to sleep.
    Anyone have any idea how I can stop this happening?
    Thanks.

    Apple requires the AC adapter to be connected when running in clamshell mode, see http://support.apple.com/kb/HT1308?viewlocale=en_US
    You can use insomniaX to prevent sleep when running on batteries, see http://www.macupdate.com/info.php/id/22211/insomniax

  • External Monitors with MBP

    Hi.
    Is it possible to connect two external monitors to the Macbook Pro at all?
    Thanks
    Chris

    Mirroring is not possible,even with the matrox adapter (and others like it). It will only turn your two displays into one "big" display.
    However, Display port supports daisy chaining monitors. Unfortunately, OSX does not as of right now. Perhaps in the future it will.
