MacBook :: Getting Rid Of Vertical Black Columns On Computer Screen / When It Is Connected To Projector

Aug 26, 2014

My macbook is running Mavericks OS X 10.9.4, and I'm having difficulty getting rid of the vertical black columns on my computer screen when it is connected to my classroom projector.  I've played with the resolutions, and the best resolution for the VGA display is 1024x768...Unfortunately this creates less than desirable black columns on my computer screen.  Another teacher in my school has display settings of "1024x768 stretched," and her macbook does not have the issue mine does.  However, I don't think she is running Mavericks 10.9.4.  I cannot find this display option on my computer.

Info:
MacBook, OS X Mavericks (10.9.4)

MacBook Pro :: Pink And Green Vertical Pixel Columns On Screen?

Sep 2, 2010

My A1226 is really giving me fits. It will display persistent vertical pink and green pixel column patterns in windows or over the entire screen at start up. I have twice performed the "PRAM Re-set" with Command-Option-P-R depressed with pwer on and that has worked. But tonight it came back and I had to do it a third time. Is this a potential or probable power/battery problem? I hope someone here is familiar with this!

MacBook Pro :: Red Vertical Lines For Black Screen?

Mar 13, 2010

My MacBookPro 15" 5.3 worked fine until today, All the blacks (rgb 0,0,0) on the screen become red stripes.

When I boot into Linux or Windows the same problem appears, so it's probably a hardware problem.

I have no expensive adaptor to connect to an external lcd screen, so I don't know yet if the problem is in the mac screen or in the cabling or somewhere else...

Here are 2 screenshots of black squares a drawed in Illustrator, one taken on the mac (cmd + shift + 3)

one taken with a camera (where you can see the red lines)

I want to avoid the MacStore as I want to avoid missing my laptop for a month...

MacBook Pro :: Vertical Stripes At Boot Then Black Screen?

Feb 23, 2010

I have a MacBook Pro with Leopard. On boot, I get a screen of vertical blue stripes with the Apple logo, sometimes intact, sometimes split across the stripes. The spinning activity wheel is there too. After about 30 seconds, it gives up the ghost and the screen goes blank. It's still powered on, but just the screen is blank.

I've attached an image of what the screen looks like.

I've tried Command Option PR to reset the PRAM and VRAM but the problem remains. Any ideas?

Intel Mac :: Vertical Black And White Lines On Screen

Mar 5, 2012

Simply using my Imac for watching tv on the web, Hulu, and left to help my wife get groceries in the house. My wife checked her email and closed Safari.

I came back in roughly 10 minutes from when she shut down Safari to see a black screen with white pinstriping, and the mac being totally unresponsive. Shut down and rebooted, sent off the report to Apple, and am now here with seemingly no problems. 

Needless to say, as a photographer this computer is just about as important as my camera. Should I be worried? discovered the thread to this issue, which appears to be quite extensive.

iMac (24-inch Early 2008), Mac OS X (10.6.8)

The line is not majorly visible, but it is just annoying considering i payed �1000 for this iMac.

Picture1: Line overlapping my iTunes.

MacBook Pro :: While Connected To A Projector?

I was doing a presentation the other day and had some issues.  I was connected to a projector and until I rebooted, I was unable to get the projector to project the image on my computer.  instead, it was projecting the "milky way" image from somewhere on my computer.

MacBook Pro :: Black Screen After Waking Up From Sleep With Connected Dell Display?

Aug 17, 2009

I have a 2 month old 13" MBP which I absolutely love. The only hitch is that there is an oddity when connected to my Dell 2008wfp display. It only happens when I wake the MBP from sleep. A number of things happen sometimes. Usuaully, when I wake the MBP from sleep, i get a black screen on both displays and all I can see and control is the cursor. Sometimes the main display will be black, but the MBP display will show the desktop wallpaper, but again, I can only see and control the mouse cursor. It should also be worth mentioning that the keyboard is rendered non-functional as well.

Sometimes, OS X will appear on both displays, with mouse cursor active, keyboard inactive, but I am unable to click anything or interact with anything OS X.

Anyway, I'm at the point where I need to mention this because it happens quite frequently and its getting rather annoying. The only way I can get out of this hang, is to cold reboot the machine. It happens everyday and at least 50% of the time I wake the MBP from sleep. When not connected to the display, I never get this occurrence. Also, this display worked perfectly when I used to own the classic 15" MBP, so its hard for me to pinpoint what exactly is the anomaly that is happening.

Anyone else experiencing this same issue? I am using a mini display port to DVI adapter to the Dell display.

MacBook :: Unibody Display - Connected To External Monitor - Black Screen

May 7, 2010

Well my unibody macbook display decided to screw up last night, it was working fine last night no problem. Connected to a external monitor. I fell asleep last night with front row left on, obviously it went to sleep and then I woke up and the screen was black. Now the LED lights are working, my external display is also working. The display settings recognize a screen being present (when I click detect displays and gather windows - 2 windows appear). Ive reset PRAM, SMC, reseated the RAM, control+shift+eject (which just made the screen flicker a little after turning it back on) and Im out of ideas. Its out of warranty and about about 18months old.

IMac :: 21.5" Vertical Black Line/Mark Down Left Hand Side Of Screen?

Sep 11, 2010

I have only recently started noticing this, it is mostly visible on the white screen at boot up but just faintly noticed it now against my background.

It is a fading black line going down the left hand side of the screen, it starts at the top kind of fades in the middle then comes out again.

I honestly have no idea what this is, i will try catch a picture on my phone soon and post it up.

Cheers.

UPDATE: Sometimes the line is clear, sometimes it is faint and even sometimes it isn't even there!

MacBook Pro :: New Mbp Connected To An LCD Projector - High Mbp Fan Rpm's

Sep 24, 2009

I had my new mbp connected to an LCD projector for class the other day. At the end of class I disconnected it and put it in my bag. When I got back to the my office I took it out and it was burning hot everywhere. I opened it up, there wasn't a response, but it eventually restarted. Everything seemed fine. Since then, I have connected it to the tv at home a few times to watch some shows, and the exhaust gets going at a fairly high rate. I never noticed the sound of the fan before, but iStat says its going at 6200+ rpm and its quite loud. It doesn't really feel hot. Anything to worry about or am I just being paranoid about my new baby?

OS X Mavericks :: MacBook Pro Freezes When Connected To LCD Projector

Sep 3, 2014

it's running 10.9.4. every time I hook it up to the projector where I teach, it hangs and then eventually freezes entirely, prompting a hard reboot. I don't understand why it is doing this to me. I just used it at a conference in March and it didn't do this. But suddenly at this new school, it cannot deal with the projector.

MacBook Air :: Plugging Into Wrong Port - Computer Screen Goes Black

Dec 15, 2010

I was BBMing while trying to plug in my headphones with my pheripherals, and I accidentally pushed it (not very hard) into the USB port. The tip of the headphone jack connected with the little connector ball at the bottom of the USB port. The screen went black and I instantly hit the power button on instinct, so I don't know if it shut off. Did I do something very bad, or is that normal? I'm not sure if that's even considered an electric shock or what.

OS X V10.7 Lion :: Macbook Pro Screen Remains Black After Opening Computer

Apr 29, 2012

When I open my macbook, the screen remains black (as though it's in sleep mode). Adjusting the brightness always fixes this problem, but this is a temporary fix. The brightness is not at zero when I adjust it after opening, often I need to dim the screen to reactivate it.

This problem is not: related to *clamshell mode*related to unintentionally dimming the screen. related to any of the settings in the Energy Saving panel in system preferences

Extra info: The computer seems as though it doesn't actually enter sleep mode when I close the computer.I don't think there are any processes running that would prevent sleep mode. I really just want the computer to go to sleep properly when I close the screen and more importantly, that it wake-up when opened, or at least when a button is pushed aside from the brightness buttons.

OS X ::macbook Cursor Disappearing / Leaving Only A Few Black Vertical Stripes

Mar 17, 2009

My cursor (in all forms) on my macbook seems to be disappearing--it appears that every other column of pixels has gone clear as well as a clear border, leaving only a few black vertical stripes as the normal cursor. It's a black outline when it's the hand and it's a few colored stripes when it's the spinning wait cursor.

Interestingly, when you do the ctrl+zoom in a few degrees, the cursor reappears.

If anyone thinks it matters, I was in the middle of backing up via time machine when it disappeared...

MacBook Pro :: Blue And Black Vertical Lines On Startup Then Freeze 10.7.3

May 14, 2012

I have a 2007 MacBookPro. shortly after installing Lion 10.7.3  and VectorWorks 2011 I started getting vertical blue and black lines across my screen on startup. They remain with in the apple while the computer boots and the everything freezes. I tried all of the usual fixes, recovery, safe boot, reset PRAM, battery, etc.When I tried to boot of a system disc I get a message sating that I need to restart my computer. Upon restart same problem occurs. 2 months ago I took the whole thing apart and cleaned out the guts.  Reconnecting all cables back together, I came across, what I think is the camera cable.  Since my camera has been erratic, i decided to test the problem with it connected and then disconnected. Connected same problem. Once i unplugged the camera everything went back to normal, until now. The same problem returned. I cleaned out the guts again. This time I unplugged the hard drive to try and boot off the C drive, but still get the same problem.  This morning It decided to boot up. I was able to copy my essential files onto an external drive.

PowerPC :: IBook G4 - Blue Screen With Black Box Asking To Restart Computer

Feb 8, 2009

Everytime I turn it on I get a black box asking to shut down or restart the mac. I have managed to get it to turn on to powersave and managed to update the software. Thought it might help but just made it worse - it won't boot up at all now past an apple symbol with a little swirly thingy underneath (I apologise now for my lack of intelligence when it comes to computers/knowledge/names of things!) The first time I managed to boot the computer up it came up with the grey screen and a little folder flashing between a face and a question mark which I assume meant it couldn't find anything but that appears to have gone away now. I bought this computer new from Apple about 2 - 3 years ago and no disks were provided with it.

When I pull the cable out of the usb port on the imac, the computer screen comes on and then I reinsert the cable back into the usb port in the computer to use the wired mouse (wired mouse works fine after I reinsert the cable back into the usb port).Could this problem be associated with the wired mouse or with the usb ports on the imac?
