OS X V10.7 Lion :: Occasional Graphics Errors On External Monitor?
Mar 19, 2012
Occasionally however, I have video graphics glitches on my MacBook Pro. Sometimes it happens when using an external monitor, sometimes it also happens on the notebook display. I often get a distorted task switcher:Also, Safari sometimes renders the content in a weird way, with yellow and red blocks:And finally, the translucent part of the taskbar sometimes looks funny, with stray pixels running through: I wanted to mention that it's not a big concern, but when typing the previous version of this message, I detached the external monitor and then all I got was a black screen when opening the lid. I had to power down the MacBook.

I want to run an Imac and an external Monitor, but I want to use the complete graphics power on the external Monitor, so no mirroring of the displays. Is there any way to shut down the internal display?

my 2.4ghz 3 year old macbook pro is experiencing a lot of graphics errors and lockups recently, where the screen will turn garbled and such and the computer will freeze. Keep in mind this is the 8600m gt. However, I just got the nvidia fix done for free by apple a couple months ago. Is it possible it could be the same problem?

I just bought a 2TB OWC Mercury Elite Pro drive. And I'm passing data (mostly video) onto it from a WD MyBook drive. Both use the Journaled HSF format. I'm on a MacBook Pro (10.5.8).
Problem? Every so often I get a message saying "The Finder cannot complete the operation because some data......could not be read or written." And once this happens, the transfer falls into some limbo land � it won't copy any more but i can't get rid of the "copy" window showing the halted progress. I actually have to reboot just to begin the transferring process with another folder.
So what goes? In the last case, it was some JPG file that appeared to stop the action, usually it's some kind of video file. But I can't find any rhyme or reason to why this occurs, nor can I find any distinguishing characteristic of the offending files.

I wasn't sure whether to put this post it iTunes (since all my music is played in iTunes) or in Mac Lion.I purchased a new external HD because my old one is about to fail. However, the old one is working fine right now. I have both HD's plugged in to my laptop. I am trying to transfer the music files from one to the other. But the copying gets stuck, and after several minutes, says one of the over 1,000 songs has an error and the copying is stopped. Without choosing a few songs at a time and copying that way, and then removing the file the error message shows, which will take a long time, is there any work around for this?

I have a 27" i7. I have a 24" DVI Montior hooked up to it via MDP->DVI adaptor. When the 24" Monitor is on, everything is fine. When I turn the monitor off, the magic mouse tracking on the 27" screen stutters. I am not kidding - it took me ages to figure out that to fix I either need to turn the other monitor on OR disconnect the MDP->DVI adaptor.

I was just upgraded from a 13" mbp on 10.6 to a 15" mbp on 10.7.3 and I'mn having a lot of issues with the UI changes. The biggest bother at the moment deals with window positions when I undock my laptop to take it to a meeting. I unplug all the cables, head to a meeting, and when I get back and plug everything in, my external monitor shows a blank desktop. I need to drag everything back into place for a two display setup.
If I move the menu bar to the external display everything will shoot over to the external display when docked, leaving the mbp screen empty. This is a real pain and I can't figure out what purpose it serves.
Is there a setting I could change to correct this behavior?

I have a 27" iMac and have connected a Philips 160e as a pallette monitor via a Mini Display Port to VGA adaptor. the iMac sees it but auto picks the wrong resolution 1280 x 1024 (stretched) instead of the Philips' 1366 x 768 @ 60Hz.
If I try to change the resolution the screen goes black which is symptomatic of using the wrong refresh rate, and of course I can make no further adjustments. esc does not get me out of the black screen.
What is worse the iMac seems to remember the wrong resolution/refresh rate after restarts.
I have tried Safe Mode (it stayed black) and booting off an external hard drive into another system (back into black if I change the display settings).
I have gone into System Preferences > Display > Color >unchecked 'Show profiles for this display only' > selected > Philips 160E in the list
It only contains .icc profile information, which I suppose is to be expected but is the only access I can find to any specific model data. The same display works fine with an older 24" iMac, using a different adaptor because of the different display port.
Somewhere OSX is storing the settings for the external monitor, I'd love to be able to trash it or change it back.

I have two WD Elements external HDs. I use a Belkin powered 2-port USB hub to connect them to my Airport Extreme (used as a server). I started out with one of them, a 1.5 TB, and purchased the second one when the first started to get really full. I use them exclusively for storing music files. My plan was to move files from the nearly full drive to the new one. I began moving files, folder by folder (a painstaking and time-consuming process) from the one drive to the other.
The first problem that popped up was this: in the process of copying a folder to the new drive, an error message appeared saying that the "operation could not be completed because you do not have access to some of the items." I in fact have full custom access to both drives, and am the only one who uses them. Another message I would sometimes get would be, "[file name] could not be moved because its name contains too many characters."
I found this annoying but bearable until it started happening more frequently. What's more, when a folder failed to copy completely, that would leave me with an identically named but incomplete folder in the second location. An attempt to delete it would be met by another error message, "[folder name] could not be deleted because [folder or file name] is in use.

my problem is since the update to 10.7.3, Lion isn't waking up from standby when I have left my external Monitor attached to my MacBook Pro. It will flash the keyboard backlight, but both displays remain black. And when i disconnect the external one, nothing happens. Only possibility to come out of this state: Hold power button for some seconds until it shutds down "hard".

Computer: Macbook Pro 13 inch purchased Spring 2011 OS: Mac - Lion (10.7.3), Boot Camp - Windows 7 (64 bit) Utilizing an adaptor, I'm able to use my Samsung monitor without I problem when working in the Mac operating system. Unfortunatlely, when I switch to Windows 7 / Boot Camp partition, plugging in the Samsung makes both the external and laptop monitors go blank. I have spent hours researching this, but I have be unable to come up with solution. It seems like the problem might have something to do with the NVIDIA drivers.

I have a 27" iMac and I'm using Samsung SyncMaster SA850 as a second monitor (connected via a display Port cable with a mini Display Port adapter). Everything worked fine until yesterday - the Samsung screen turned black and now it only works with max resolution 1280 x 1024 (native is 2440x1440). I think I upgraded Lion 10.7.2 to 10.7.3 (I don't remember for sure though). When I connect the monitor to an iMac with 10.7.2 everything works fine. And another iMac with 10.7.3 has the same problem as me.

I am trying to back up my hard drive to an external (WD My Passport Essential SE) in Disk Utilities (after booting failed). Was getting error-61 until I changed the external format to Mac OS X compatible. But now I am getting an input/output error.
I'm probably going to need to erase my HD and reinstall Lion, so I HAVE to back-up.

If there's no refresh this coming week, we're pretty much going to be forced into settling for one of the 27" iMacs (we're on our third) and hooking up a second (probably 24") monitor to do color sensitive work.
Does anyone out there have a dual-monitor setup running with the 27"? I was wondering if you notice any sort of graphics performance hit with the second monitor attached.

I have a G4 powerbook with an LCD that only displays the top 25% of the screen. I've been using an external monitor with it just fine. Today, I reinstalled the OS and ran into a problem. The main OSX startup menu (you know, where it asks for your location, timezone, personal info, etc) is prompting me for information, and I can't see the forms to fill them in! The external monitor defaults to "extended" as opposed to "mirrored", and the forms are embedded, meaning I can't drag them over to my external monitor. Obviously, if I can't fill out these forms and get to the desktop, the laptop is completely useless.
Does anyone know how to force the external monitor to be "mirrored" from startup? Is there a keycommand?

I have been using the latest macbook pro 13.3" since April 2010. Over the last week the monitor suddenly goes completely white and the external monitor goes black. The laptop becomes unresponsive although the programmes opened continue running (e.g a skype voice call would continue without interruption although the monitor is all white).
The only solution at the moment is to press the turn off button for a few seconds then switch the laptop on again. It will then work normally until for no apparent reason this happens again.

Firstly sorry if this has been answered before
I have a 2 x 2.8 Mac Pro and want to have dual monitors for Photoshop and Dreamweaver development

What is the best solution for dual monitor support.

Does the ATI 4870 support 2 DVI monitors with adaptors?
Can I use the 4870 with the 2600??

Do not want a nuisance to escalate into a serious problem thru benign neglect. Random black screen -- Turn monitor off then on, and all comes back fine. No loss of power in machine, no fan quirks, no overheating. Is it the Monitor? or the graphics card?

I picked up a new MacBook yesterday and I noticed a weird issue when coming out of "monitor sleep" mode, not regular sleep mode.
When I move the mouse, the external monitor shows what you see in the picture, kinda like a TV with no signal. The MacBook screen works fine so what I just do is unplug and re-plug in the DVI plug and everything is good again.
My 24 inch Dell monitor worked fine with my M1330 and other computers so I know it's not that. Does anyone have the same issue or maybe give me some light on this?

Is there a way to use my external monitor as my only monitor when connected to my mbp? Or, can i clone my display, but at separate resolutions? I am able to do this on windows with nvidia software, is there software that allows further customization?

I have a 22" Dell external monitor on my MBP. I know that I just close the cover to my MBP to shut off the screen. What do I do in those instances that I want to use both screens? There has to be something simpler than restarting the MBP?

As said, my current set up is an HDMI - DVI cable (HDMI to monitor and DVI to adapter) and my DVI - mini DisplayPort adapter, everything is connected fine but when I turn on the monitor, it says cable not found... and nothing is displayed on the screen but on the Macbook side of things, it sees the monitor is connected (I can extend the screen and leave the screen) but other than that, it appears I cannot get an image on the monitor, pressing every button on the monitor does not work either.
Any other information that may seem necessary, let me know. I tried clearing my PRAM and clearing the power and such but nothing seems to work.
