Why doesn't my MBP recognize my DVI external display?

After using my MBP and 30" Dell 3008WFP monitor for about 2 years... the system quit recognizing the display.
No dropping the MBP, no software updates, no unusual activity, no cable changes... nothing. One day it works the next it doesn't.
I've read so many blogs earlier today with people fixating on cables and adapters, but I'm not sure they have much to do with this one... because nothing has changed in my experience, but the MBP no longer detects the display and the display no longer detects the MBP?
I've tried changing eerything, but no luck. Can anyone help me sort this out? Thanks in advance for your replies...

You need to set them up via 'system preferences'.
On your pop up screen go to preferences and then to print&fax
From there use the + button to add a printer of your choice...
Be aware that some printers do not have automatic drivers for mac and therefore you may need to get that from the internet... unfortunately most makers treat Windows as priority still!
I have a very expensive pair of printers in my office the B&W works and the Colour cannot use a Mac driver, go figure!

Why doesn't my itunes recognize my ipod nano 6th gen anymore?

I recently purchased a lot of new songs and downloaded the newest version of itunes. Now when i plug my ipod (6th gen) into the USB to sync with itunes it shows that it is charging ("connected - eject before disconnecting") then it ejects itself and the whole time itunes never registers my ipod. So frustrating!! I've restarted my computer many times, i've uninstalled and reinstalled Itunes many times. I've tried holding the sleep/on/off button with the volume down button to restore it then i get a message from itunes saying that it can't restore my ipod because of an error..... What can I do??? Please Help!!!!

Why doesn't my iTunes recognize my "Songs for Japan" CD,
iTunes gets information about all CDs from a database called Gracenote (which has nothing to do with iTunes/Apple), but if no one has entered the information about that CD into Gracenote, that's why your iTunes cannot fill in the track names. You could send that information to Gracenote yourself by completing the track names and artists and then clicking on Advanced/Submit CD track names. That would help everyone else in the future.
However, you then go on to say;

If your iTunes cannot get any track information for any CD, then either your iTunes isn't connected to the internet, or your iTunes setting have changed. To check your iTunes settings, go into Edit/Preferences/General and look at the tick-box (check-box) named Automatically retrieve CD track names from the internet. There should be a tick (check-mark) in the box.

HT4623 Why doesn't my iPad recognize an update to iOS 7? When I try to update, it says, "iOS 5.1.1 Your software is up to date."

Why doesn't my iPad recognize an update to iOS 7? When I try to update, it says, "iOS 5.1.1 Your software is up to date."

Because you have a 1st generation iPad and iOS 5.1.1 is the last update for it.
It will not get any further iOS updates beyond 5.1.1
iOS 7 requires at least an iPad 2

I have an Apple Powerbook G4, and my monitor doesn't function. I have an external display Monitor, however it's stuck in extended screen mode. How do I get it to mirror or duplicate the display without use of the on-board?

As i had said, I have an Apple Powerbook G4, and my monitor doesn't function. I have an external display Monitor, however it's stuck in extended screen mode. How do I get it to mirror or duplicate the display without use of the on-board? Is there a Fn key combo i'm missing or is the issue more serious then i realize? any and all help and hints would be greatly apprichiated, thanks in advance.
-Powerbook User

The PowerBooks have an F-key that toggles mirrored and extended mode. My PB is loaned out right now but I think it was f7. The keycap has an icon on two overlapping rectangles, as I recall.
EDIT: Yes! Found a pdf of the PB manual it shows F7 is the toggle:

Unibody MBP owners with *working* external displays, please chime in.

I'm trying to determine if there's any use at this time to try to exchange the MBP (unibody) I have now with another unit in the hopes of getting proper external display support. (To be clear, I'm referring to the external display problems many of us are having, like in this thread, and this one, and others.)
I'm sure there are others suffering from this problem who are simply seeking another datapoint in determining whether or not exchanging one's unibody MBP for another are of any use at this time. So the question here is:
If you have a unibody MBP, and you are successfully driving an external monitor without issue (using the Mini DisplayPort to DVI Adapter), can you kindly post the following information?
1) External display model (manufacturer and model)
2) External display screen resolution
3) Any information about DVI cable, length, brand if applicable, etc.
4) Have you confirmed proper operation in both 9400 and 9600 GPU modes?
5) If you know, is your MBP equipped with the 9c84 or 9c85 built-in display panel?
6) If your setup wasn't originally working, but now is working due to a unit swap or swapping out of the Mini DisplayPort to DVI Adapter with a new one, can you kindly note that?
Please do not consider yourself representative of a properly working external display setup if yours looks mostly good, with just minor artifacting--that is, for the purpose of this thread, please consider "working" to mean only perfectly normal operation of an external monitor from your unibody MBP.
Are all of the above points necessarily relevant? I don't know yet, but I figured it's best to try to get as much information from those who have working units, to try to determine what's relevant and what isn't.
Why am I asking this? Because I've already wasted enough time with this unibody MacBook Pro, now on my third unit, and I do not want to waste time making trips to the store to exchange units (and the time necessary for restoring to the new unit, etc.) if it's not going to help things. (The previous two replacements had nothing to do with this particular problem, and I didn't have my external display until the third unit, so have no idea if the previous two suffered from this particular problem or not.) If it seems that an exchange from one unibody MBP to another isn't going to help, then those of us who need to resolve this might learn more information with which to make a decision. Right now, I'm seriously considering exchanging for the current 17" MBP with matte display, even though it's not the new unibody design, and doesn't quite match up in the specifications with the new 15" MBP--I just need to get my setup working, and figure the older style of the 17" might be more tested and worked out.
Thanks in advance to those of you who fit the bill and answer these questions.
NOTE: If you have more relevant information to ask of those with working setups, please do; but please avoid the discussion of your problems if you're among the ones (like me) with external display issues, as there are other threads for the discussion of that (like the ones linked above). Ideally, I envision this thread as more populated by the responses of those with working setups.

Mine works perfect.. This is AFTER a logic board replacement for the 9600's BSOD problem
1) Dell 2007WMP
2) 1680x1050
3) Cable that came with monitor
4) Post repair only really using 9600, though 9400 seemed fine too
5) LG (9C84)
6) Logic board replaced last week for BSOD problem. (That board had external monitor refusing to wake problem as well).

Closing MBP Without Sleep With External Display

Greetings.
I have just hooked up a Dell 23" flatscreen display to my Macbook Pro. Everything works great... connected it via the DVI cable and it worked immediately.
I'd like to be able to turn on my MBP and use the large display exclusively, meaning I want to be able to close the MBP without it sleeping. I have put my Energy Saver preferences on "Never" for the display and computer itself, but those options do not work.
What is the protocol for closing the MBP after startup so that I may use my display without the whole thing going to sleep?
Oddly, I was able to "trick" the MBP into closing at one point; I shut the clamshell, it fell asleep along with the Dell 23", then I reopened it just slightly to where it would awake again. Then I used the display for a little while and shut the MBP clamshell again and the 23 still worked while the MBP was closed. Not sure how/why it worked, and I have not been able to duplicate it.
The split screen option is neat, as far as like the MBP being on the left and the 23" being on the right, but I don't need it, and my desk is too small anyway.
How can I achieve MBP sleep while it is still powering my big display?
Thanks,
C

Ha. Welp, best $8 I ever spent.
I SWWWEEEAAARRR I tried that earlier this afternoon; also I like totally swear I looked up and down the support site too. I knew it would be easy, just not that easy.
Thanks!

MBP or Air - using external displays

Hi All,
Looking at getting a MBP or Air for work, want to know how easy and how well Leopard goes from dual display to single display. I'll be using a VGA adapter initially.
My current MS laptop doesn't handle being plugged into, or unplugged an external display - the display settings often seem to change by themselves. However, it is the devil I know - is Leopard better, or worse?
Looking for general experiences using a MBP or Air OPEN with a second display.
Do you need to put the computer to sleep to plug or unplug the display?
Cheers, Chris

Hi WBW,
Thanks - sounds pretty good.
A follow up question - when using dual screens, I can place some applications on the second (external) display. When I unplug the external dispaly, how does Leopard handle this? Do the apps reappear on the laptop screen, or are they in another 'space'?
Can spaces be used in conjunction with an external display?
Chris

MBP no longer drives external display @ 1920x1200

I have been using an external LaCie 526 display on my MBP at the native res of 1920x1200 for almost a year. Today after running a keynote presentation on an LCD projector (may be coincidental) I can only get the dvi to drive it at 1280x720. All of the standard rubber chicken tricks don't have any effect (reset PR, detect displays, turn on/off mirroring, etc). Like many others in this forum using the DVI to analog svga connection does allow the higher res.
Any suggestions much appreciated.

Lots of people are having issues with external displays since there was a manufacturing defect with the nVidia 8600M graphics chip inside the Macbook Pro. You may want to run the Apple Hardware Test from the cd your Mac came with and see if it gives you any errors with the video controller.

MBP i7 and Dual External Displays

is it possible to run 2 external 1200x1600 dvi(digital) displays from a MacBook Pro 15" i7?

The cheapest way to do this is probably to use the mini-display port for one monitor , and a USB or firewire based video out card for the other.
It may produce some latency issues , but if you need a cheap fix it might do the job for you.
http://daggle.com/macbook-pro-multimonitor-4-monitors-at-once-1577 may give you some ideas on the matter.

Lots of red dots on MBP 2010 internal and external display

Hi all,
Anyone's got any suggestions?
Over the last months there's been an increasing number of red dots all over the display (both MBP's own display and when connected to external display). The dots appear on different places (not static dead pixels) and especially where darker graphics appear (when playing games or just watching pictures or editing pictures, for instance). Especially playing games is impossible because of this graphics distortion. However, the degree of the problem varies.
Is this a hardware or software problem? I haven't had any problems with Apple hardware before.
Best,
Thomas

Thanks for the suggestions. I haven't had the opportunity to test on a different OS / boot, but I did try to change the energy saving settings as advised, but the problem persists.
Is it possible to attach an image file (screenshot of the issue) here?

Why doesn't Migration Assistant recognize my backup disk after rolling back to Mountain Lion from Mavericks?

I rolled back my OS from Mavericks to Mountain Lion and now the Migration Assistant isn't finding my Time Machine backups. Any idea why this is?

One reason may be a different computer name. Check System Preferences > Sharing and make sure your computer name has been the same through all your various OS X iterations.

Why doesn't Photoshop CS6 recognizes its Twain Driver

I've downloaded the Twain driver for Photoshop CS6 from Adobe and copied the Twain.plugin file to the Photoshop Plugin directory in Applications. I'm using a Mac with 10.6.8. I then restarted CS6 but there isn't a mention of 'Twain' in the Import menu? So also not my scanner. Which is an Epson Stylus SX130. Why not?

Is your scanner driver 64-bit?

Why doesn't Extension Manager recognize InDesign CC app?

I'm using the following:
Mac OS X - Version 10.6.8
Adobe InDesign CC - Version 9.2.2
Adobe Extension Manager CC - Version 7.3.2.39
When I try to use my Extension Manager, it's not recognizing my Adobe InDesign CC application.
When I try to install a .zxp file, I get this error: Please make sure the manifest.xml of this extension is valid and the Extension Manager recognizes at least one product which the extension supports.

Run the cleaner tool and start from scratch. This is probably some version conflict in the installer database
