MacBook Pro :: Display Won't Work Without A Second Display Plugged In?
Mar 31, 2012
I'm using a Dynex Mini DisplayPort to DVI Adaptor to use a second display (an older display, I'll admit). After I have unplugged the adaptor, my MacBook still tries to read the second display, and switches back-and-forth between a blue screen & my desktop. It stabilizes once I plug the adaptor back in. What is causing this problem, and how do I fix it so I can use my primary display without having the adaptor constantly plugged in?
Info:
MacBook Pro (15-inch Early 2011), Mac OS X (10.6.8)

I have a white plastic macbook which appears not to be able to connect to my wireless network. All the other PCs and a Mac Mini in the house connect fine, but the macbook does not.It has connected since i got it, both to the home network and a network in school, but today it promted me for the wireless password, connected a few times but did not give me a IP address, and now will not connect at all! The network appears in the list, i click on it, enter the wireless password, then it says connecting before connection failed.
The network setup is a Cisco router connected to the modem and then connected to the wireless too. There are no computers connected via cable to the network.

I want to buy the 27" iMac - but only if I can use it as external monitor for my Lenovo laptop when working from home. A the Apple store in London they said that this is possible with a Belkin converter from hdmi to mini display port (with a USB power caple to turn it into an active signal). The laptop also has a displayport.

I have this gorgeous 22" ACD that I have plugged into my G5, where I use it quite often. But my intention for the G5 was to be a server, which it is. I often need some extra display space when I'm doing school work, or coding, so I was wondering if there is a way that I can use the display, while plugged in to the G5, as an external display for my MBP. Preferably something that I could stream over my local network.

My boss just gave me a MBP Core I7 2,66Ghz / 4GB Ram, model mid-2010 for the business. It is equipped with Nvidia GeForce GT330M as PCIe video card. If I plug an external monitor, I have, after some time between minutes or hours of work, a weird video problem, which obliged me to power off/on the MBP. Sometimes I even can see my mouse moving, but I can't do anything with it. If I do not use the external monitor I do not have problem. This type of problem appears around 3-4 times a day and make the MBP unusable, as I'm loosing the recent work each time the problem occurred.
Here is the extract of the console at the time of the crash :13/03/12 16:45:51,203com.apple.kextcache/: no supported helper partitions to update.13/03/12 16:47:29,000kernelNVDA(CopyEngine): Channel exception! exception type = 0x27 = CE0:

The problem seems related to NVidia GPU. I've reinstalled everything from scratch without success.

We have an iMac G5 running 10.4.11 which developed some nasty colour banding down the screen and have now plugged in an external display. How can you turn off the iMac display so it only outputs through the external monitor?

This is an odd, intermittent problem that started about a month or two after purchasing my fall 2011 MBP 15 (i7 2.5, 16GB RAM). This problem started, went away on its own, and now it's back after about two months of being trouble free.When I close my computer, it doesn't go to sleep.The slit light on the right front of the computer does not go into its slow flash mode; however, it does light up solid, and theng it stays lit.When I open the lid, the computer wakes up immediately (it was never "sleeping" to begin with), but then after a second or two the screen fades to black.The screen can be brought back to life by pressing either of the brightness buttons on the keyboard.I took it to the Genius Bar, and of course I couldn't replicate the problem for them.When I got back home, I decided to test the computer plugged in, and that's when the problem came back.I don't know why it went away previously.So, in summary: The issue only occurs when the computer is plugged in.The sleep problem existed before I installed 3rd party RAM and Parallels 7, and they exist now after I have installed the RAM and new software.I use a wireless mouse, and the little dongle has no effect on the sleep issue - the computer will not sleep (when plugged in) either with or without the dongle in a USB port.The battery charges just fine.All of my software is up-to-date, and I'm running OS X 10.7.3I have checked for the Flashfake malware, and I do not have it.I am running Sophos Anti-virus; I have done a scan, and have found no threats.They flashed my PRAM and ran some tests at the Apple Store and everything passed.

My wife's macbook monitor is destroyed due to happy 2 year old. It won't be worthwhile to replace the monitor and it is not fixable without some expensive work being done on it, therefore I would like to use our TV as an external monitor and retire the macbook to being a mediia computer. I have connected it to the TV, and I see an empty desktop, as far as I can determine it looks like it is treating the TV as a secondary display - that the desktop is extended onto - so I cannot actually interact with the normal desktop. When I try to run things using keyboard shortcuts I hear some sounds of things starting, but I don't see anything on the TV.  So what I need to do is to have some way to tell it to treat the secondary display as the primary display.

have had the macbook air connected to HD TV using the mini tv - HD connector, but it's stopped working. Tried ON-OFF, wiggling it, used Detect Display but it just won't find it any more. Last thing I did was download a movie using SKYGO last night, but don't see why this would effect it. Â

I hooked up my macbook pro to a mini display port to a dvi -> hdmi to my tv no problem. However, when I hooked up the mini display -> dell monitor, I get nothing. The screen is black. The weird thing is that my macbook pro recognizes that a second monitor is plugged in... it just won't display anything

My external display (HP w2207) seems to conflict with my MacBook Pro (15 inch Retina display, early 2013) since I upgraded MacBook OS to 10.9.4.The external display works at initial boot of Mac but does not work after OS sleeps and I attempt to awaken, and while the external display is not waking, the Retina display flashes through different screen views, which only partially reflect my normal screen, or do not reflect my normal screen at all.Â

I have a mid-late 2008 MacBook connected to a Dell U2211H monitor using a Mini DisplayPort -> VGA connection.
When I use 1920x1080, I only get 60 Hz and the display is a fuzzy (text). Also, there are black bars. Why?
Will my issues be solved using a Mini DisplayPort -> DVI connection? Or should I exchange it for the 2209?

My brand new 15 inch MacBook Pro was working fine for a week. Today the display went to sleep and when I tried to wake it, it remained dark, items barely visible. I could see the display brightness meter changing, but the brightness did not. Restarting didn't help. Called Apple and they're going to replace the computer. Has this happened to anybody else? Note: I have the hi-res anti-glare display.

I have an early 2008 MBP 15" (I think detailed specs are in my signature) and recently (over the last week or so) when I move my laptop display up and down (physically), the screen has this thing where it gets inverted and what not. It is very annoying, and I have been having to constantly fiddle with it everytime I move my laptop around (I use it both as a desktop and as a laptop, so this happens a lot). I recently switched to using it clamshell mode as a means of avoiding this in desktop mode, but occasionally I'll still need to move it around places and what not. I was wondering if anyone has had this problem before, or has any ideas as to what might be a better solution. I would take it in for repair, but I don't really have 300+ dollars to spend on a repair right now. I think it might be related to the data cable connection to the display of the computer, since it is rather intermitment, and requires fiddling for the screen to not be inverted/messed up/displaying black lines, etc. I can post more details about it, pictures or something if that would help any of you geniuses out there as well.

I have a Macbook with Snow Leopard and I plugged an auxiliary display on mini-dvi port. The display of the Macbook is my primary display and the other is the secondary. Is there any way to set the auxiliary display to be primary and the Macbook display to secondary?

I have the Apple 24 inch LED display which has the glass panel. Do you think it would be strange to pair the 15 or 17 inch MBP with the matte anti glare display with the 24" display? It would be used mostly with the external display so I'm wondering if it makes more sense for both panels to be the same. As I already have the external display I'm not open to getting something else. I'm just wondering if having the different types of displays would mess with my eyes.

I use MBP (late 2011). I find the hunderbolt port to be similar to the mini-display port of older mac. I wish to have another display, but not ready to spend $999 over a thunderbolt display from mac. So would like to know if a Mini-diaplay port converter from apple would help me connect a exernal display via the thunderbolt port?

If there's a thread on this, feel free to close this one, but I searched and couldn't find anything. I need a guide on how to remove the display casing on a unibody MBP with an anti glare screen. Specifically, how to remove the actual top shell, where the Apple logo is. The LCD panel itself, I don't need to take apart. Is this possible? If someone has a link to a guide, that would be awesome.

I'm used to using the keystrokes control-shift-eject to put the display to sleep without activating the screensaver or putting the whole computer to sleep.Â
Since the new Macbook Pro with Retina Display lacks an eject key, the best I have been able to do is set a hot corner. I don't like this as much -- especially since it is possible to trigger the hot corner without intending to.

I have a macbook pro with retina display that was purchased in 2012 and I am running Mavericks. I have been trying to mirror my mac to my apple tv but the the airplay icon will not display on the menu bar. I have tried turning airplay on and off on the apple tv without success. Under the display settings in system preferences it says No Devices Detected.I have already tried all the suggestions in the support pages to no avail.

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?

So my buddy brought over his first-generation-aluminum 20" cinema display. I have a DisplayPort to VGA connector, and a vga-dvi converter, and I plugged the cinema display into that. Nothing is showing up on the cinema display - it's just black.

I have a 15inch Macbook Pro from Late 2007; well it worked just fine yesterday, but as of this morning the display will not work! It makes the Chime when you power it up, but no screen display; you can adjust the volume buttons and hear that it is on and the volume can be adjusted. The screen brightener and dimmer does nothing, as well as the keys brightener and dimmer. The apple website said to reset the PRAM which I did and then if that didn't work to reset the SMC which I did and got no change in my problem. And now the part that boggles my mind is I have the cables to hook up the MBP to my TV so I figured I'd atleast be able see it on the TV if the display has crapped out but its doesn't transmit the image to there either. Is it possible I caught a virus that kills displaying ability?

I'm thinking about updating my Macbook Pro C2D 15'', which is already 3 years old. I'm planning to get the 27'' Apple Cinema Display (finally!) when it come out later next month. I've decided that I'd go with 15'' Core i7 Macbook Pro, but couldn't make up my mind on the screen resolution; Standard 1440x900 or Hi-Res 1680x1050.The thing that really bugs me that the pixel-per-inch (PPI) of the MBP and ACD. The ACD 27'' has 108.79 PPI, with relatively close to 110.27 PPI on STD MBP, while the High-Res MBP will give me 128.65 PPI. This would mean that the text on the High-Res MBP screen would be a bit smaller.So, my question would be for the person who're using current ACD (24'' ?) with Hi-Res 15'' MBP or 17'' MBP (which has 113.xx PPI):1. Does the difference in text size seems noticeable when you switching from one screen to another?

I just order the new MacBook 15" with the new 2880x1800 Retaina Display.Â
But I'm gong to run Windows 7 (and 8) on the machine, which have nerver been a problem on my current MacBooks/iMacs. But now I wonder how Windows will handle this resolution?Â
Windows has a DPI setting that makes everything bigger on a high resolution display. I never used it, and I don't know how well it works. Is that the way to go? Would you change the order to a none retina display, if you were me?Â

Windows 7
