MacBook Pro :: Odd Line Appear On Black Screen Display
Jul 8, 2010
I have a core i7 MBP with the high res display, and when the display is showing black, a horizontal green line appears on the screen. It is only visible when the screen is showing black or another very very dark color, and the line is not visible with the screen off. It isnt something on the screen, as rubbing it does not affect it at all. I cannot post a screenshot of it, because it does not appear in the screenshot (it does on my screen, because the line is there physically, but on other monitors it is not visible).
basically i bought my macbook literally two days ago and it worked perfectly for the first day and it still does except for the fact that there is a mysterious black line on the screen that appeared from nowhere! i have tried restarting it multiple times and i have never touched the screen violently...when i take a screen capture it doesn't show!!! i could swear I've never even touched the screen.
I have had my MacBook Pro since November so it's still new. I take great care of it. This morning, I opened it up and noticed a small black line present under the screen. It has not been dropped, moved, beaten up, etc. It doesn't look like a broken pixel and all of the dead pixel fixers I have tried have not worked. Not sure what to do now. I live two hours away from the closest apple store and I cannot afford to send it out for fixing because I am an online student and need the computer daily.
I am getting a green line and a black open space on the side of my Mac Mini TV when I set it up. I have tried every different resolution and it is still there. The problem is that when I click Detect Displays, nothing happens to the screen.
Recently, a vertical black line (maybe slightly dotted) appeared running down the screen of my iMac G5 (Power PC processor). On the left of the line the screen appears fuzzy while on the right it's OK.
Has anyone experienced this before? Hope to hear from someone who has.
So today I noticed a small black bar on the corner of my screen. I tried to get a screen shot of it, but i couldn't, like it was off the screen. However, my mouse dissapears under it when i move it there.It is a little hard to distinguish because it is the 2.4 ghz macbook aluminum, glossy screen so it has the black surrounding it, but it is definably there. This all along the right hand edge of the screen.
Although there is a chance it may have always been there, I am not so sure. I think there are lines along the top and left hand sides, but they are much smaller. again it is hard to tell. I am fairly sure that there is none on the bottom of screen. Is this normal, or what? I have applecare, and I didn't do anything to my macbook. Although it is getting me a little OCDish, and is slightly annoying, and I know these things on the screen tend to expand.
I have an iMac 2.8 24 inch, about Two years old running 10.5.7 , when I start the computer it shows the normal Gray screen for about 30 seconds, then the screen goes all Black , but with a small flashing white line ( _ ) in the top Left hand side corner.
It just stays all Black for ever , I then hold down the On / Off button and turn off the computer, I then hold down the keyboard '' option key '' and press the on button at the same time , then I get the option to start from the main HDD , I click the Icon and the computer then starts normally , and every thing runs ok.
Can some one please tell me what I have to do to get my iMac to start up normally again , Ive run Repair Disk permissions but the problem still occurs . Over the last few day's Ive been trying out a few new applications, so not too sure if this has any thing to do with this current problem
I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?
Whenever I try to use Screen Sharing to control this one particular Mac Mini, and someone else is using the mini, and I pick "Connect to Virtual Display", I get dropped to a grey linen screen. Like the login screen, but without a list of usernames or anything. There it sits. Here is what I see in the console of the mac mini when I try and use a virtual display from the other machine:Â

I've had this iMac about a year now, and i have had this problem for a while but thought i'de leave it for abit and see if it heals its self. As sometimes the line is more visible than other times and sometimes it's not even there!
I have 2 pictures which i snapped with my iPhone, so i will link you too them.
The line is not majorly visible, but it is just annoying considering i payed �1000 for this iMac.
My screen had black and white vertical lines pop up over the entire screen then went blank and now at a restart the password then loading spinning circle happens then I get a blank white screen.It's a 27 in Intel iMac that is about 2011/12 purchase
So I've got my MBP that I've had for about 4 months, the thing is. It just recently started to have screen flickering issues. I'll be sitting doing w/e as usual and all of a sudden the display goes dark, almost black, for a second, then comes back up again. I have yet to find any trend in when this is happening, but it is definitely happening on battery as well as plugged in, but it seems to be getting worse.any one have any idea what this could be, something I can fix on my own, or should I take it in?
Today, I bought a vga adapter for my unibody macbook and it is not working. I hooked it on a 22 inch Samsung 225MW screen and it the screen shows a message "check your cable (PC)".
I have a MacBook Pro (13'', Early 2011) & iMac (21.5", Mid 2011) using a Thunderbolt Cable to Target Display. Everything was working find and I could Command F2 to Target Display as expected.However, about a week about this stopped working. Now when I try to Target Display the iMac goes to a Black screen (like it's switching to Target Display) and the MacBook Pro does nothing. The iMac will be at the Black screen until I Command F2 again (or disconnect the Thunderbolt Cable), then the iMac goes back to the normal display. I have tried another Thunderbolt cable with no luck. I have perform all software updates on both machines (now both running 10.7.3) and fixed Disk Permissions. I have also found that restarting my MacBook Pro allows this to function as excepected (Command F2, Blue Flashing Screen, Target Display on the iMac). However, this is not an ideal situation since having to restart my computer is time consuming. Â
I have a early 2011 MacBook Pro 13" running the latest version of Lion. I have been using my MacBook with an external monitor since I brought it in 2011 and have had no problems with connecting it to my external monitor. Connected via mini display port DVI adapter and a DVI cable to a Philips monitor.
Two days ago when I plugged the MacBook back in to the monitor I connected and but now only displays a black screen, I can move the mouse off the MacBook screen and over to the external monitor and back but it is not displayed on the monitor. I have tried connecting other devices to the monitor and they work fine.

my macbook air 13 display only black screen and pointer when wake up from sleep. its not frequently happen. to become normal it take 10-15 sec, is it hardware problem or software problem?
Macbook pro 2014 only had it for about 2 months but recently about three weeks ago the display has been flicking to a black screen but has gradually been increasing and it now happens every two minutes - just randomly goes black for about 5 or 10 seconds and sometimes goes back to home screen but sometimes goes to log in screen, It interferes with me trying to do my work when this happens so frequently
Info: MacBook Air, iOS 4.3.3, Transferring from Windows XP
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.
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.
My Mac Book Pro just stopped accepting commands, the screen is freezing on a black screen and the keys have no bearing on the situation. The only way I can get it to stop is pull the battery out. It has been acting funny lately.

I've noticed that when my rMBP (late 2013, Mavericks) turns off the display automatically while on battery (as configured via Energy Saver) and I try to wake it immediately, I get a black screen with the cursor, rather than my password/unlock screen. It remains a black screen, with the cursor moveable, for 5-10 seconds or so, and then the password/unlock screen will appear as usual.Â
This does not happen if:I don't try to wake the display/computer immediately after automatic display sleep (e.g., I wait 5-10 seconds and it's fine)I turn off the display using a hot corner and immediately wake the displayI put the computer to sleep by closing the lid and immediately wake it by opening the lidI select Sleep from the System/Apple menu and immediately wake it by pressing a key or clicking on the trackpadÂ
Why automatic display sleep is causing this temporary black screen? I currently get around it by setting the time for automatic display sleep while on battery to 10 minutes instead of the default 3 minutes to minimize the chances of needing to immediately wake the screen. I'd like to keep it at 3 minutes if possible to maximize energy savings, but the temporary black screen is really annoying if I didn't really want display sleep and consequently have to wake immediately.
Soo...I just picked up a mini to run plex and use as a media center. Hooking it up to my projector via VGA cable. When I set the display settings to the native resolution on the projector there is a small black line or bar down the left hand side of the screen. Not on the right but only on the left. why this would be happening?
I have a Mac Pro (Early 2008) running on 10.5.8 OSX with apple 20" display and 16G RAM.
Initially started with my MACPRO not waking up from sleep and has to force the shut down with power button. Finally realised it was due to my Epson scanner connected via USB...
The main issues now is with the display, black screen on startup. I can still control the volume and disk eject/close, just no display. Force shut down with power button numerous time but futile. Finally solved it with SMC reset.
it becomes an on and off issues... and continuously I solved it with SMC reset.... sometimes needed 2 or 3 resets to get it to work,and finally for the past few days... SMC reset can't solve it either... no display on startup, and same thing I can control the volume and disk eject/close. Have tried my monitor on other mac and it worked fine.
Now this is strange. if I let the mac cool off totally,after a SMC reset. the display will comes up fine...
I was browsing the internet, not doing anything major, put the computer to sleep, came back 10 minutes later... black screen. I messed with it for an hour or so and determined that the video card went bad (I'm guessing. It's a mid 2007 macbook pro with the nvidia geforce 8600m. My secondary monitor remains black as well). In the midst of totally freaking out, I decided to activate the voiceover utility, enable screen sharing (after figuring out a slew of keyboard commands I didn't know about), and logged in from my girlfriends computer.
I immediately closed all the windows and applications that I had inadvertently opened during the blind wtf session, and opened up system profiler to see if it is recognizing a video card. Well, it is! It's listing the video card as a GMA x3100! Is there a secondary card in there? Cause if there is, it's not working either. Or is that just a default they would put in if it doesn't recognize a video card? Doesn't seem likely. Or, because I'm using screen sharing, is it picking up my girlfriends card? It's not, because she's using a GMA 950. Maybe it's splitting the difference?
