Second display problems

I've tried to hook my macbook pro to 2 different displays, they both showed a very pink image, that gets more and more pink around the contours, I've tried calibration but it didn;t work

Were they both the same type of monitor? Exactly what monitors are they? Maybe they are the problem?

HT5313 Second Display Problem after Update v10.7.5

I just updated my MacBook Pro (Late 2011) and the new OS 10.7.5 is not recognizing my second display (VGA connected emachines 19''). I have restarted, changed the resolution, and tried many things, but the display that was working perfectly two hours ago now does not work. Help pls

Hi There,
I suggested the solution on the link you refer (to solve this type of problem with gfxCardStatus)... unfortunately this solution did not solve the problem when upgrading to the 10.7.5, namely the new "supplemental update" that was released on the 4th of October (http://support.apple.com/kb/DL1599).
Here is a simple procedure I followed and solved the problem for me... this worked by chance after starting following the instructions in: https://discussions.apple.com/message/19979833#19979833.
Restart your machine and, when the machine is in booting press "alt" (left option) to show a booting menu.
Select "recovery mode" (do this with the external display connected)
In the recovery mode you can test if the external display is detected (it should work normally)
Do not do anything in the recovery mode... simply Restart you machine (now in normal mode)
It should work normally now... (at least it worked for me)
I think this has to do with a kind of "reset" on the external displays configurations... But I still do not fully understand why this happened.
I hope this helps some people! Cheers!

I have a strange second display problem.

I have a late 2007 20"iMac with a Dell UltraSharp 18" second display. I am running Snow Leopard with all updates.
This setup has been working great for some 3 1/2 years up to about two weeks ago. Suddenly it is like the left 20% of my second display is unresponsive to the mouse, display is displaying everything OK and the muse pointer can move there, but the click is not doing anything. For example, if I put a Safari window on this screen and click of any of the links in this area nothing happens, however if I move the whole Safari window so the left side is 20% or more from the left edge of the display the same links are just fine.
Anybody ever seen this and know how to fix it?
Thanks, Bjarne

OK, no trouble shooting. The first thing I'd attempt is restarting in Safe Mode. If you still don't have luck try doing both a SMC and PRAM reset, it wouldn't hurt to do the SMC reset a couple of times. If still no luck let us know.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Windows 7 second display problems

I purchaced a mac mini mid 2011 server and have windows installed through boot camp. Both my displays were working fine, until I upgraded my ram to 16gb. Now it always believes there to be two displays, even when the system is restarted withouth the mini display port to vga adapter plugged in. My HDMI tv is getting the signal fine, but the monitor does not display anything. I've messed arround with lots of settings, and I'm not sure how to make it work again.
Basically
-changed to 16 gb crucial ram
-windows 7 always thinks that there are two displays running, but will only display to the one on the HDMI
-booting ubuntu through it's install on windows 7 works fine
-OSX displays on both fine.
Any ideas?
Thanks

Problem with second display in premiere CS5

Hi. I have a problem with external device, I have Mac Pro with ATI radeon HD 5770 and two displays 24 LED display that is primary and second 27 LED cinema display, in Premiere on external device only none and DV 720 576 and no second display.

That's the thing, Steve. Using the secondary monitor for playback, it should not be able to show any part of the desktop at any time. It should show only black if nothing is playing, or it should show what is playing in one of Premiere Pro's monitors. But never the desktop.

Problems with FCP and my second display

Hi everyone !
I'd like to use for my editing and color correction a second display. I bought the JVC DT-V24L1D monitor, and plugged it into my MBP through a matrox mxo.
When inside FCP, I cannot find a way to display the canevas into my JVC screen, it displays the whole screen i already have on my laptop. I read the manual a good hundred times, and by following what is written I just got nothing. Can please somebody help me finding a way to set FCP ? Thanks.

You are probably better off posting this in the FCP forum, where there are several Matrox MXO users, but since I'm one, I'll give it a go.
When you install the Matrox software, you should have a whole new group of easy setups in FCP using the Matrox. If you are working with standard DV footage, choose the appropriate Matrox setup; i.e., Matrox MXO DV NTSC 720x480. There are also setups for HDV, etc.
After choosing an easy setup, and starting a new project, go to the view menu, and set your external video and audio to the same settings as the easy setup, if they aren't already correct.
Using Command/F12, you can switch from your regular display on the 2nd monitor to the FCP canvas.
A couple of other things to mention: for existing projects, you can change all of the above in your sequence settings, and under the View/External Video settings.
And, in system prefs/displays, set up your external display so that it is not mirroring the desktop; then you can create a dual display window arrangement in FCP, so that when you're not using the Matrox for viewing the canvas, you can have an expanded timeline, more space for your browser, etc., etc.
You can save your custom window arrangement, and toggle between it and the Matrox canvas view with the above mentioned Command/F12.

Msi big bang xpower2 - only boots for 10 seconds, displays error b7

Hey guys,
As the title states. I am getting 'b7' on the error display which i read somewhere means 'no input devices detected', can someone confirm this? I have tried turning on the PC with 1 GPU, 2 GPU, and no GPU in different configurations but I get the same error each time. It just boots for 10 seconds, displays 'b7' and then restarts and does it all over again. Help would be massively appreciated as I need this PC for work :(
Thanks

IMac with Snow Leopard doesn t work without second display connected

Hi,
I've a iMac 24" and I would like to resell it urgently.
But I've a big problem, if I disconnect my second display (belinea 20"), the iMac screen become grey or blue after many second.
If I boot system, after the grey clock : nothing, grey or black screen.
The Os is snow leopard disc, update version (10.6)
The iMac version is iMa8,1
The EFI bios is : IM81.00c1.b00
I tried :
Reinstall with format
Utility disc on boot cd (scan disk & rights repair)
Even when I try to boot cd without second screen, I ve white screen
(after a update to 10.6.4)
Help me please

Hi Tony,
I don't how these instructions are the same, here is what the article says:
_Resetting PRAM and NVRAM_
• Shut down the computer.
• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
• Hold the keys down until the computer restarts and you hear the startup sound for the second time.
• Release the keys.
Your original post said *"Restart the mac and depress the alt, command, P and R keys simultaneously. You should hear the boot chime. Keep the keys depressed until you hear the boot chime a further three times. On the final boot chime release the keys and let the mac boot normally."* How I understand your post that totals 4 chimes vs. the 2 Apple specifies. Am I missing something?

24" imac with second display that flickers on and off randomly

Hi, I'm a n00b here, I've read a handful of threads before posting this a I cant seem to find a definitive answer.
I have a 24" 2.4Ghz aluminium iMac and I've recently purchased a HP zr24w 24" IPS panel as a second display, connected with an apple miniDVI - DVI connector.
The screen flickers off, to totaly black every time the mac seems to be having a hard time doing something, be it fast scrolling, flash video, but someimes randomly.
I have boot camp installed with winblows vista (for work) the screen does EXACTLY the same thing, all be it less frequently. This for me rules out the Mac OS, i think it must be something video card/driver related.
Was there ever a fix for this? most of the threads seem to just die with no official answer, it would appear that MBP users were ok until the last 10.6.3 update, when the problem seems to have returned, although i think thats a different issue with the same net effect.
I have spoken to apple care and the very helpful girl I spoke to send me some logging software which I've run and sent the logs back, that may help them out someway.
Any help would be GREAT !!
many thanks
Michael

well, some time has passed, here's where I'm at so far.
I tried a friend's samsung 24" screen and all was good with the world, no flickering on and off, no black outs nothing, for days it was all fine. I swapped the HP monitor back on and it went right back to its old ways. I called HP tech support, they decided that the monitor was faulty, i returned it to where I got it from and they have sent me a new one. Which was fine, for about 7 hours!!
So, to recap, the mini-DVI to DVI adapter is fine as it worked on the samsung screen, the HP screen is brand new and exhibiting the exact same issue as the first one (cant be 2 faulty ones surely) The samsung screen was fine.
This leads me to think that there is some compatibility issue between the 24" imac and this particular (hp zr24w) monitor.
I have followed apple support's requests for data logging but they cant find anything wrong there.
I'm out of ideas, any help would be GREATLY appreciated !!!
thanks
Michael

Using my tv as a second display?

I have a few questions about adding a second display to my MBP.
1. When adding this new display, will it display the exact same thing as on my MB or will it be an additional space?
2. I decided to do this in the first place because I found a "monster" branded cable in officemax on a steal 80%off. It is branded for the Zune though. I noticed however on the display adapters for the MBP, there were similar inputs. It isn't working though.
3.When I plug the wire into the earphone jack, audio comes through my tv. The output next to it (on the left) I assumed was the display output and doesn't work. Is this the correct output or am I pushing my luck and should buy the proper cable?

2. To connect a TV use the Apple DVI to TV adapter which has a S-Video or composite output suitable for a TV. Using a Monster Zune cable , small wonder it didn't work.
The other "output" is actually an audio line input. The video output is actually on the other side and is a DVI port to be used with the above adapter.
I presume this Zune thing has a plug like the size for a iPod or similar small earphone size with three conductors on it? Might work in an iPod but connecting it to a line in will never work. In this case the Zune-iness is not the problem vs. using the completely wrong connector.

Hi G5 Gurus,
The display problem first, we all know when screen savers display, a click on the mouse will bring you back to the active desktop, this was how it worked., but now, sometimes a click cause the G5 to sleep!
As for the sleep, I dare not to put it to sleep these days, because I am afriad it may cause a fire by over heating. Sometmes, actually four times in the past few months, my G5 could wake up by itself, followed by a extrem high speed running of the cooling fan, it sounded like a hair dryer running in the same room. Sometimes the sreen could light up, just like real wake up, sometimes, it was black. No clicks the mouse or keyboeard could bring it back to normal, I had to press and hold the power button to turn it off.
This crazy problem happened for the first time last summer, a dead hard disk was the cost. Apple replaced it, but failed to detect the cooling or power or display problem. I was given one month extended free service, but right after its end, the problem was back and happened even more often.
Please let me know if any of you had the same problem and please advise what to do.
100s Gs of thanks.

I have the EXACT same problem. In fact, I could not have described it better myself. What gives? I brought it in to the "genius" bar and they repolaced the power supply free of charge but the problem is still there. I noticed they ordered a new logic board but did not end up replacing it after all. Did you have yours replaced and did it work? Is this a known issue?

Hi La teller,
Thank you for your reply. The 'genius' here in London only replace the dead hard disk, which I belive was a victim of this problem. I was told they couldn't find anything wrong with the power supply or the cooling system.
Now at lest I know I am not the only bad luck guy. Let's wait and see if others are having the same problem. I am not sure if this is a known issue to Apple, even if it is, it may take years before they can offer a recall or free repaire. I noticed that some G5s have already been suffering from power problems and a free repaire was offered.
Thank you again and hope Apple can take our concerns into their consideration soon.

Hello,
I'm also having this problem (fan running, won't come out of sleep), just spoke with an apple care rep. He confirmed my suspition that it was software, not hardware as I have just had the logic board and power supply replaced.
His suggestions were to:
1. Run disk repair from the startup CD
try running OS X from a firewire drive and see if the same behavior happens or
perform and archive and install.
When the fan starts to run like that it means the OS is not communicating with the hardware properly. The OS could be somewhat corrupt if you were having hardware issues beforehand, hence the need for a reinstall. I will be performing an archive and install after the disk repair, I'll let you know if it fixes the problem!

Hi Stopha6,
Thank you for your message. I never imagined it could be a software issue, cos it looked so hardware.
Please keep me updated with your progress.
By the way, as I said in my old posts, a hard disk went dead when this happened for the very first time, how do you read this?
Thank you.

Hi Stopha6,
After reading your reply again, I realized that the system had already been reinstalled. As I said when it happened for the first time, the hard disk died with it, which was replaced, of course with a new OS X, but the same problem is still happening. May this suggest that it is not just a software problem? Thank you. Songyan

The Fans going at full is only because you have an application that is using a lot of cpu power and therefore causing the imac to heat up so it turns the fans on. The screen-saver and sleep problem you describe sounds like something that may just happen on accident. But this sounds mostly like a software problem. Try making sure to always quit all non-apple products and see if anything changes.

Thank you, Ag-Nate. I will try as you adivised but I con't think the fans were activeted my intensive CPU using. In most of the cases, the problems happened when the Mac was sleeping, when the minimum CPU were being used.

"The Fans going at full is only because you have an application that is using a lot of cpu power and therefore causing the imac to heat up so it turns the fans on."
That's only partly right. A hard-working process will make the fans run at high speed, of course.
But, the OS is in touch with the firmware of the iMac, telling it how to run the fans, based upon information the OS X kernel is getting about the state of the hardware.
If the firmware loses touch with the OS for some reason, and is not getting instructions on how to run the fan, it will default to running them at full blast, to be on the safe side (and this "full blast" fan mode is way louder than anything you'll generally experience during normal usage, I know from experience).
So it may not be so simple as a hard-working cpu process kicking the fans on.

Hi I have a 20" G5 imac it's about 18 months old and I am having the same problem, It freezes and the fan runs really loud. It's nothing to do with software as my I.T. guy has done a complete re-install. All of our admin people have imacs of differring ages and the flat panels are all OK but every one of the G5s has had a booting problem. Some fell into the recall for replacement logic boards but the one I have at home is the newest and doesn't. I'm waiting for my apple reseller to get back to me, but it looks like it's the logic board and as none of the serial numbers fall into the recall, I'm expecting a big bill. I'm really disappointed as I've been a professional apple user for over 15 years and have grown to expect a certain amount of honesty and integrity from them. Looking at all of the discussion boards and the amount of people complaining of the same problem the logic boards are defective and apple should be replacing these free of charge.

I am having a very similar problem. My G5 imac has already had the logic board replaced from the leaking capacitor problem. 8 mos. later the power supply was replaced under the second recall program when it failed to start up.
It had been working now for almost a year, when about 3 mos. ago I started to experience the sudden dimming effect - if the display was untouched the screen would dim about 30% similar to a laptop in energy save mode. I checked and none of these types of options were set in the pref panes. At the same time I would have the iMac go to sleep after a while from non-use, and then when I tried to wake it it would stir for a few seconds and then go right back to sleep. It took 2-3 attempts to wake it up.
Then last week, as I tried to wake it, it just shut down instead completely. I had to hold the power button down to recycle it to get it to come back to life (3 times).
Today was it - I found what I thought was a sleeping iMac, but it will not power up at all. I opened the back cover and the power supply is working, but I cannot get the board to energize, I reset the PMU, but the #2 LED won't even blink. It is completely dead.
Basically every time I used this computer I held my breath that it would not work. After 2 recalls I still only get 9 mos. out of it? Apple is really starting to show it is like the "big" computer makers, the quality is going right down the tubes.

My Mac Pro (2006) with NVidia GeForce 8800 GT is not detecting a second display. What can I do?

My Mac Pro w/ NVIDIA GeForce 8800 GT does not detect a second display from the System Preferences / Displays. Even though I select the "Detect Displays" button, nothing happens. I also have Bootcamp and Windows 7 in a partition on my drive. When I operate with Windows 7, there is no problem detecting both of my displays. However, when I operate with Windows 7, there is no sound signal sent from my sound card. When I switch back to the OS X then I get a sound feed from the sound card, but then it will not detect more than one monitor. I'm ready to pull out my hair. Anyone have suggestions?

My Mac Pro Desk Top computer no longer can "see" my second display??

I've tried reversing the connections on the back of the MacPro but it still doesn't "see" the second display. I've had these two displays hooked up for years with no problems. I recently upgraded to Mountain Lion and I just had the MacPro in the Apple Store for a "One To One" transfer of data to my new MacBook Pro laptop. When I brought it back home it still worked fine. I then was cleaning up some stuff and I know I went into my "Users and Groups" panel in System Preferences and I did remove some items from the "Login Items" list that open automatically so maybe that is the problem?? I know the second display is getting power and recognizes it's connection to the compuiter because when I disconnect it, it says, "no signal" and when I reconnect it, it just goes to sleep. Advice appreciated.

Some of the graphics cards that had two DVI connectors had one Dual-Link (suitable for all resolutions including wider than 1920 wide) and one Single-Link (suitable for resolutions up to 1920, but not wider). This does not appear to be your problem, since both are less than 1920 wide.
The "Drivers" business is a complete Red Herring (Not Applicable), as the Mac does not use Drivers for displays -- it uses a unified driver for the Display CARD, and customizes it based on the capabilities reported by the Display when connected. In order to get this to work, the display must correctly self-identify.
To verify that the display is correctly detected, look in:
About This Mac > ( More Info ) > Graphics and Displays ...
... a correctly self-identified display shows its Name and its maximum resolution. be skeptical, this information does not update when you plug/unplug the display, and you have to close and re-open this window (or possibly the entire program) to get the information to refresh after a change.
If either display provides a USB cord, it must be plugged in to complete the display connection and provide display ID and control (this is much more common with Apple displays that third-party displays).
Is there any evidence of trauma to the display connectors or cables? Any bent pins on the connectors?
