Mac Pro :: Using Dual Monitors / Screen Makes Blue Flashes?
May 15, 2008
I just hooked up a 2nd monitor to my early '08 Mac Pro and when in OSX the screens start to go blank/blue for about 1 second intervals. They flash together sometimes, and other times sort of independantly to each other. When the desktop comes back on it fades in like its animated rather than like its cutting in and out.
It seems fine when I disconnect one monitor.Running 10.5.2 all updates 8 core 2.8ghz with 10gb ram and 8800GT
On my 1st Gen Mac Pro, I suddenly get a strange blue screen out of no where. Everything on the screen freezes for a few seconds then the screen flashes blue for another few seconds. After the screen comes back from the blue, everything works perfectly again. Even when listening to music, music pauses for a few seconds and then comes back. This happens a couple times a week and its getting on my nerves. Sometimes it lasts for a long time and requires a hard restart.
I have tried reinstalling Leopard/tried hardware test/upgraded to the 8800GT video card and the 3870/I cleaned the whole inside of the box with compressed air. I even took her into the apple store and had a genius look at it over night. They told me everything is working perfectly. Ofcourse it started doing it again after I got home with it. The apple store suggested that I could always replace the logic board but they want over $1000.00 for that and I dont know if its worth it.
One simple question, do exist the possibility to connect 2 DVI Monitors, both HD, to a MacBook Pro 15" in order to "extend" the screen? No need to keep the MacBook pro LCD on. What is needed to succeed?
I just bought a new monitor to use as a secondary display with my MBP. I'm trying to watch a video in Firefox on my secondary display, when I try to watch the video in full screen and move back the mouse on my MBP display and click on that display. The video on my secondary display will exit full screen. How do I stop this from happening?
I've got dual monitors up and running for the first time. With my workflow, I'll be working at one monitor for several hours and then the other for several hours. I'd like to have independent screen savers for each monitor so the one not being used won't get burn in, etc., but I don't see any way to do that.
Perhaps I'm answering my own question here, but I would suppose that if I'm in extended mode (which I'll be doing) it's really just one big screen, so there isn't a way to tell the other screen to start running a screen saver....and if I'm mirroring, they're both doing exactly the same thing. Those pieces of logic tell me that I can't do what I want to do.
My MBP was updated from 10.5.2 to 10.5.4 (combined update) this morning and, after the installation finished, it rebooted into a blue screen. I restarted it several times and always went into blue screen.
Now, the interesting part is that this is not the "blue screen after install" problem others are experiencing. If I disconnect the external monitor during restart and wait for OS X to start everything works fine. After OS X starts properly I can even reconnect the external monitor and it works fine. In fact I am writing this post from my MBP using the external monitor right now.
Since some document on the Apple Support website was suggesting to remove the file ApplicationEnhancer.bundle in System/Library/SystemConfiguration when experiencing blue screens after the install of 10.5.4, I did look in that folder for that file but it's not there...
I have iMac 27 and screen problem on start up i have blue vertical lines, when it start i have a lot of blue dots and nothing else. when I connect outside monitor its showing the same.
Just installed lion and still the same problem when it starts blue dots, when startup in safe mode loads of blue lines and dots on the screen.
I have recently bought a 13" Macbook Pro and wanted to hook up an external display (an oldish acer 19"). I have a Mini Displayport to DVI adapter hooked up to a DVI -VGA adapter which leads to the display. I haven't got it to work yet. I have followed advice about closing the lid and using usb mouse and keyboard with no luck. The only thing that happens is that the screen on the laptop flashes blue for about a second after plugging in the Mini DisplayPort adapter.
I'm curious if anyone has tried out Spaces with Dual Monitors yet?I'm not sure if it will matter or not, would kind of be cool to be able to specify which space goes to which monitor.....I have a New iMac with extra 20" LCD and will be upgrading to Leopard tonight, so I guess I'll know then...just wondering what to expect.
So I was using my second monitor to run my G5 while transferring files to my new 3.2 octo, and then the past week I was using it to transfer my old PC files to my new PC. Now I finally just went to hook it up as my second monitor on my Mac Pro, and found out that I CAN'T FIT BOTH DVI CABLES TO THE PORTS!!!
They're too close together so I can fit one monitor into either port, but not both simultaneously. My monitors are the aluminum 23" ACD's w/ DVI.
I was wondering if in anyway possible on a mac I can make my two monitors at the moment act as one virtual monitor? Know what I mean? So I want like one extra wide resolution which would cover both screens, not a separate resolution for each. Hope this is possible, much be in some way.
Is it possible to run two monitors independently via a hardware device with the macbook air? I would like to do it with a device that works well but doesn't cost a fortune.
Does anyone know how to get hot corners to work on dual displays? I had a monitor plugged into my MBP 2.5ghz and after changing the relative location of the monitor in display settings, left of main screen to top of main screen, the lower left corner would allow me to access Expose for the applications in the current monitor, instead of exposing all application windows on both screens. This feature is very helpful though I cannot repeat it. Is there a certain orientation of the monitors that will allow each screen to have it's own hot corners functioning for that screen of was this just a fluke?
it would be nice to be working on one screen and watching a movie on the other without the movie expose ing when I only want to expose the applications/windows on the monitor who's corner I accessed.
So as of now I have my 13" MacBook White connected to my Dell 20" S2009W, and I'd really like to add another S2009W, but I'm looking for the BEST possible solution to do this. I've looked at DualHead2Go, and Diamond.
how to setup dual monitors. I have a 2009 Mac Pro with a ATI Radeon HD 4870. I dont see the options in the Display settings. Also I I get nothing on the second monitor?
I have an intel imac and would like to set up a second monitor to allow for more simultaneous side-by-side space when I do programming/editing. As I'm not interested in paying $1000+ for an apple monitor, I'd like to use a third party one. Thus far, I think I need a VGA to MiniDVI adapter [url], but then can I use ANY monitor that has a VGA port? And then will it be as simple as plugging in the second monitor and detecting it? Will the iMac screen remain unchanged? Will the computer just "know" when I scroll across one screen to the other
Just picked up a minty Power Mac G4 Quick Silver and two ADC Studio Displays. I'd like to hookup both displays, but I only see one ADC port. What's my lease expensive dual ADC display option for this machine?
I do not know much about this, so if i don't explain clearly, ask and i'll try again.
So basically, i have an iMac 21.5" Late 09 model here and a LOGIK TV next to it that has a channel for 'PC', i was wondering if it was possible to use them as 'dual monitors' for the iMac?
I have the setup in my sig and I'm running one Dell 24" at 1920x1200. The thing is that I'm considering getting another monitor exactly the same so I can run dual monitors, but I've read that some people have had some lock-up issues while attempting this. My question is who wide spread is this before I go and drop $600 on another monitor?
I am a web developer, and we are a Windows shop, but many of us are moving to Macs since we can run both OS X and Windows on the same machine. Well my work is purchasing a Macbook Pro for me, and I'll be hooking up an external monitor to it to replicate the dual monitor setup I have now.
As I learned in the OS X forum, I'm able to specify which programs I would like to launch in which "Space" upon boot. My question is, is VM Fusionware compatible with a dual monitor setup? As an example, could Space "1" contain my OS X desktop on both monitors, and then if I switch over to Space "2" which has VM Fusionware running with Windows, will the windows desktop span both screens as well?
I are disagreeing over the new MAC Mini and the two video cable connections on the back. He said it will support dual monitors and I said it is just a different type of connection for one monitor.
I�m looking to setup another monitor for my 07-08 iMac, I have tried searching and googling for an answer but don�t seem to have had much luck, so I have got a few questions.
1. Is my iMac even able to support dual monitors?
2. If so how would I go about this?
3. Will just any monitor work or has to be a certain type?
This has been going on since the beginning of time: You put 1 YouTube video in fullscreen (on screen #1). You click anywhere on screen #2 and screen #1 leaves fullscreen! Is there an app or script that will allow me (and the rest of the world) to watch 2 flash videos in full screen on 2 monitors? I even tried 1 video in Safari and one in FireFox but to no avail.
I have a macbook 2006 model with the mini-dvi connector. It has snow leopoard installed. I plugged in 1 external monitor and it displays 1680x1050 resolution on that monitor which is perfect. What can I expect if I split that DVI output with a DVI splitter to two monitors?
I have a Mac Pro 1,1 with a flashed ATI Radeon HD 4870 XFX. Had no problems with it ever.
Installed Mac OS X 10.6.3 software update and now the second monitor says No Input detected. Switched second monitor to first monitor and it worked fine, but the second DVI port no longer works.
Need to get this figured ASAP as I have a lot of work to do today... very unhappy with this update. Anyone else having a similar issue or have any thoughts on what to try? I've done everything I can think of.
Do I need to flash it again? Seems silly to have to flash it every time you update the OS. The video card is still recognized in System Profiler. HD 4870 with 1GB GDDDR5 VRAM.
I was wondering if it was possible to utilize dual external monitors with the Macbook pro's. With my thinkpad and a port rep I can use dual monitors as long as I keep the lid closed on the laptop. Is this possible with the new macbook's that were released today?
