OS X :: Monitor Suddenly Goes Completely White / External Monitor Goes Black
Jul 30, 2005
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.

I am running an older Macbook Pro 2008 model with OSX 10.6.8. I am getting a black and white image on my external TV. I am using the official mac DVI to composite adapter.Â
I also have bootcamp installed and use the same adapter on the Windows XP side and it works fine in full color out to a TV with the same adapter.Â

I calibrated my monitor today and now my menu bar is completely black. If I put the mouse there then I can see the items in white. Also, the titles above the icons in the dock are black. In addition, all the menus from the different programs are black also. How to get the normal menu bar, etc. back.

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 have a Macbook Pro 2.16 Core Duo, and I'm wanting to install 10.6, but about a year ago, I cracked my screen to the point that I cannot make anything out on it, and haven't replaced it. Instead, I have just been using it in clamshell mode, which has worked out fine so far. My problem is that I cannot get the 10.6 install to show up on my external monitor.
I searched around, and could only find one other similar thread that just ended with the author putting it in clamshell and having it work fine. When I boot to the install and close the screen, I just get a grey box on my external display with a black bar on either side of it. I can't seem to find any other resources, so I'm not entirely sure what to do at this point. Any help would be greatly appreciated.

It started when I was using an external monitor. There is a white line in the center of my screen on the desktop wallpaper. However it does not show up on any other screen. It does not change when I change wallpapers. I has to be a software issue because it only affects the wallpaper. Enclosed a pic of the problem. White Macbook osx 10.6.2

I recently replaced my older MBP (2007) for a MBP, 2GHz, Core i7 with thunder bolt. I normally connect to my external monitor, a Samsung SyncMaster B2230HD. This worked perfectly for my needs. I connect my MBP via a Mini Display Port to VGA adapter.Â
Display resolution:Â
VGA (External Monitor) 1920x1080 60 Hz
MBP Display 1440 x 900Â
Problem: Now with the new MBP, I get a black stripe on the left on side. (See pic)Â Â
Troubleshooting Steps:
a) Replacement VGA Cable
b) Replacement Mini Display Port Adapter
c) Tried a HDMI cable (worked but with disminish resolution and a yellow tint)
d) Adjusted both MBP and Samsung display settings include Auto Adjust.Â
I determined that the monitor is okay because the screen is filled with a lower resolution and "mirror display".

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.

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?

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.

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 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.

I have the early 2008 Mac Pro, standard configuration. I run a 30" ACD and recently added a second monitor. Ever since then I have been hearing this faint whirring sound, as if something in the machine is starting/reving up and then whirring down. It's audible to me because I have my machine sitting on top of a pedestal desk right beside my table. Does running two monitors make something inside, maybe a fan, run wierd? Could it be the fan of the video card? I am just curious, as I had not heard the sound before when I was running just one monitor. Oh, and the second monitor in question is a Wacom Cintiq. Video card is the stock ATI Radeon HD 2600 XT. I dare not open the side panel when the machine is running to check what's causing it lest I mess something up. It's like, rrrrrrrrrrrrr, rrrrrrr, rrrrrrrrrrr, like a miniature reving sound. LOL, that's the best I can do to imitate the sound. It's as audible as the sound of the regular fans.

Any ideas what's going on?

This may be of interest of more of you. I want to be able to read easier when the background is white, especially pdf files, or webpages.
I did not find a solution for certain documents, to change a background without breaking the style. I'm using the lowest brightness but I found its easier to read when I make the background gray, for example in textEdit.
ideas for pdf files ?

This afternoon I was on my MacBook pro and had to pop out so I shut down the lid as always. When I came back and opened the lid back up, all I saw on the monitor was black apart from the cusor.So I couldn't get it to shut down in any way, I hit the power button and then back on. All I was greeted with was a grey screen with not even an apple logo. I read that I needed to boot up from the installation disk and did that. On disk utilities disk 0s2 is greyed out - I tried to repair the disk but it says 'disk utility cant repair this disk'The 500gb hitachi drive has a smart status of read/wrote.Is this normal?

I have a Mac G5 Dual 2.0ghz Running 3GB Ram 6 x 512 ddr pc 3200 400mhz i use it for music production, So as you can imagine i need plenty of ram to run some of the high end plugins, So i purchased 2 x 1GB Pc3200 400mhz Ram, Pushing up my total ram to 5GB, Plenty for what i need.
So i installed the ram in the 2 outside slots(the only 2 left) the mac booted up but wouldnt recognise the new ram,( thought i would save a few pound and went for the extra value ram) So i thought i would move the other ram up a slot and put the new ram in the first slot instead of the last one, it still wouldnt recognise the new ram,So i turn it off took out the ram, put the old ram back in its original slots, Turn the mac back on,......Nothing but a white light flashing on the monitor, & the fans going mad !
After trying each set of ram in pairs one at a time i managed to get one set to work in the first slot, 1 gb (2x512) once! Now i cant get anything to boot this mac up! the ram worked before, so why not now. Ive only been using a mac for about 2 years, and before that i built pcs for a living, & i know my way round pcs fine , but this has really got me.Please Please Please. if someone can help i would be very grateful, i need to get some important work finished.
Best Regards.

Last couple of days my emac monitor will just shut down and go black, just like an old TV tube packing up used to. It won't return on restart, but did return a couple of times after I took out mains lead from side of computer, let it rest, then tried again. However, today, this solution didn't work, but a tap to the side of the computer did get the screen going. I've read a number of different possible explanations for what might be the problem - everything from battery, to airport card to it's terminally ill, get a new computer, so don't really know what to do. Don't want to go and buy a new computer if all I really needed to do was change the battery.

About half a year ago I got a Macbook Air, and a Thuderbolt monitor. Then I installed Windows 7 64-bit on it. Everything worked fine until recently the Thunderbolt monitor started to go black during Windows startup without any particular reason. Using OS/X the monitor works fine. I already scanned for malware and viruses but cannot fine any. Windows restore refuses to work? I also tried several different boot options, installed latest drivers, reinstalled bootcamp drivers but no luck so far. Â

I'm using an external Monitor (Compaq W185q) and everything's ok until I open certain webs, this websites have banners on both sides mostly, so I think that's important to tell. After couple seconds on those sites, the monitor starts flickering and then it turns black, completely. To make it work, I launch Mission Control and it starts working again, I drag the safari window back to my MBA's monitor, and problem solved. Â
