MacBook Pro :: Connecting To External Display - Apple Mini Displayport To DVI And DVI To DVI Cable

Oct 7, 2009

I have a presentation tomorrow and need to hook up my MBP to the projector in class. I bought an Apple Mini Displayport to DVI cable, and a DVI to DVI cable. I thought this would be the case, but come to find out the system does not support DVI. So I had to run to Best buy to get a DVI to VGA cable. I tried out the MDP > DVI > VGA rig on my external monitor and got nothing. The screen on my MBP responded by turning blue for a second and then back to normal...but the monitor said "No Signal". Is this some jargon with DVI-D and DVI-I? I need to know by tomorrow morning if I have to run back to the Apple Store and get a Mini Displayport to VGA cable.

IMac :: Black Screen Display When Wake Up From Sleep

Dec 21, 2010

For the past few weeks it has been going to a black screen when trying to wake it up from sleep. Either I've put it through too much work lately editing all these photos and its really tired. So, often it wakes up normally and functions fine, well, not really. It is seemingly very slow. It requires a lot of time (more than before) to open up a program or it gives me the "spinning wheel of death" when trying to go to a different page on the internet or open up a folder on my desktop. Amongst other things that require it to think. So It's just a lot slower in general than before.

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 Pro :: Black Screen With Cursor For 5-10 Seconds When Trying To Wake Immediately After Display Sleep

Jun 23, 2014

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. 

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 trackpad 

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.

OS X V10.7 Lion :: Display Remaining Black After Wake Up From Sleep

Jun 14, 2012

I have very recently upgraded to Lion on my late 2009 Intel Core 2 Duo iMac.When the machine goes to sleep on wake up - instead of going to the log on screen, the display remains black but when I move the mouse the display creates a grey pixel trace wherever the pointer should be. I also end up with the desktop clock in the top right.

To log on, I have to literally "colour in" the area where my profile icon should be which enables me to input my password.Also, on wake up, any applications that I had open like Safari, Word, iTunes etc are all closed and not open in the dock. On a separate matter, when this happens I cant wake my imac up to access my itunes library for home sharing on my ATV3 and 4S.

MacBook Pro :: Mini-DisplayPort To HDMI Disconnect Causes Sleep

Feb 24, 2012

MBP 13" (Late 2011) --> Moshi MDP to HDMI Adapter --> iogear 4x1 HDMI Matrix --> LG 24" LED DIsplay 

Xbox 360 and Tivo are also on HDMI Matrix 

I dock the MBP with all my cabling, close it, and use a Wireless Apple Magic Mouse and Wireless Apple Keyboard with it. If I switch to port 2 or 3 on the matrix, the MBP will sleep. I have installed both smartSleep and InsomiaX to try and prevent this from happening. The MBP needs to run 24/7, even if that might be damaging. To mitigate heat issues I run smcFanControl to change the minimum speed of the fan to a higher level. The Xbox 360 and Tivo access music on this Mac, and so if it is sleeping; it kind of defeats the intention I am going for here. The iogear has no possible way of signalling the MBP to sleep. Also a Gefen HDMI Detective is not a reasonable fix. Also FWIW: This happens even if I physically unplug the cable, not just if I switch the port on the matrix. Kudos to the first person who finds a permanent fix for this issue.  

tl;dr - Prevent Macbook Pro from sleeping on Mini-DisplayPort disconnection.

IMac :: Screen Goes Black And Unresponsive

Mar 31, 2010

I have been experiencing some unusual problems with my imac. While on the internet today my computer crashed on me twice, the first time the screen just showed a bunch of vertical lines, the second it flashed some random colors then went black. After the screen change the computer was unresponsive. I have a bad feeling, is it due to overheating, a bad logic board or something else. This is the first time I have ever experienced this on a mac. Has anyone had any simiar issues? Or am I up **** creek? I can't really afford a new computer seeing that I just bought an iPad (it comes Saturday). I am not sure if my computer is still under apple care and even if it was I won't get it back by the time I have to go back to college. I attached a screen shot of my computer temps.

MacBook :: External Display Via Mini DisplayPort To DVI No Longer Works

Mar 12, 2012

I had not used my external monitor in the last several weeks. I believe there have been a few OSX Lion updates since the last time I used the external monitor. I had installed all the updates prior to connecting my external monitor again. However, a few days ago I tried to connect the external monitor and all I get is a "No Signal" message on my external monitor. The Mini DisplayPort to HDMI works on my LCD TV, so I know  the MDP works. I have also replaced the MDP-to-DVI cord and the external display still doesn't work. 

I connected the external monitor to another computer running Snow Leopard and the external monitor works. So, the external monitor does work. 

I have seen a few posts aboout this, but nobody seems to have a solution that works or is directly on point to my issue. I have tried to use all the scenarios for plugging in the external monitor and external monitor power. I tried to reboot the laptop with and withoout the external monitor connected. Same thing with the exteernal monitor plugged in and no power, etc. Nothing works. I have tried to repeatedly turn the external monitor on and off while connected to the MacBook. Again, that doesn't work. Here is what I am running: 

MacBook, Aluminum 13" Late 2008
OSX 10.7.3
NVIDIA GeForce 9400M

OS X V10.7 Lion :: Black Screen Upon Wake Up After Longer Sleep?

Mar 9, 2012

In the last 2 months or so, I have seen my MacMini 2011 OSX 10.7.3 crashing withing a minute of wakeup, after sleeps of more than 2-3 hours. 

Sometimes the Black screen occurs almost immediately, sometimes it takes up to a minute after the desktop appears (after logging in). This did not occur until I got 10.7.3 and only within the last 2 months.

MacBook Pro :: Won't Start / Black Screen / Keyboard Unresponsive?

Apr 20, 2010

I have a MacBook Pro from December 2007. Currently, when I push the power button to start it up, it makes the initial sound (although sometimes this initial sound is abbreviated, like it's cut off mid sound) but it never sounds the follow-up majestic-type chime. Also, the screen remains black, and the keyboard is unresponsive (The Caps doesn't light up, for instance). The light on the front comes on faintly, but does not blink as in sleep mode. And the fan comes on as well, again faintly, not as in overdrive.

And I'm assuming this next part is coincidental but I'll relay it anyway: The first hiccup with this was yesterday when, in sleep mode, I pushed the front release button to open the MCP and then immediately afterward accidentally closed it again. Upon opening it for the second time the screen remained black. I manually shut it down holding the power button. After two or three times of turning it on and off manually, the majestic chime thing finally sounded and it booted properly. It worked fine then throughout the rest of the day when I would come back to it until last night when it failed again.

Hardware :: Apple Hints At First-party Mini DisplayPort To HDMI Adapter?

Apr 13, 2010

The specification sheet for Apple's new line of MacBook Pro notebooks states that HDMI output is possible using an optional Mini DisplayPort to HDMI adapter, hinting that Apple could release a first-party solution [Update: New ports support audio output].

The bullet point is included under the "Pure digital video output" section of the technical specifications for Apple's new MacBook Pro machines. It advertises the functionality as: "HDMI output using Mini DisplayPort to HDMI Adapter (optional)."

Apple does not make a first-party Mini DisplayPort to HDMI adapter, and there is no sign of one yet on the Apple store. Existing third-party options have been available since early 2009 for under $20. Such cables allow Macs to be connected to nearly any HDTV with HDMI for video output.

Apple does sell first-party Mini DisplayPort adapters that convert the output to VGA and DVI. Both items cost $29 direct from the hardware maker.

In March, AppleInsider exclusively reported that Apple has created in its internal labs a Mini DisplayPort to HDMI connector. The alleged hardware was said to include technology that would allows Macs shipping with an updated Mini DisplayPort spec to channel both video and audio through the Mini Display port to the HDMI adapter, rather than just video.

Update: ArsTechnica confirmed that the new Mini DisplayPort supports both audio and video output on the new MacBook Pros. However, Apple also reportedly said it has no plans to release its own HDMI adapter.

The Mini DisplayPort became a part of Apple's LED Cinema Display, MacBook and MacBook Pro lines in late 2008. It replaces DVI video with a much smaller port. The new 27-inch iMac, introduced last October, only supports DisplayPort input. Unlike the Mini-DVI and Micro-DVI connectors common on previous generation Apple products, the port is capable of driving resolutions up to 2560x1600, which is commonly used on 30-inch displays.

Though the Mini DisplayPort technology was originally created by Apple, in 2009 the Cupertino, Calif., company agreed to license the interface to the Video Electronics Standard Association for its own DisplayPort standard. Prior to the agreement, Apple had to license its technology itself and made the standard free, as an incentive for rapid adoption.

Last November, the Mini DisplayPort standard created by Apple was officially adopted by VESA, which is also finalizing the DisplayPort 1.2 standard, which will double the technology's bandwidth capabilities to 21.6GB/s.

Last week, a new patent application suggested Apple is creating a new proprietary cable that could simultaneously transmit both USB 3.0 and DisplayPort data through one cable. The described technology would offer more functionality and greater data transfer rates via smller cable connector form factor.[ View this article at AppleInsider.com ]

Hardware :: Macbook Pro 13" External Display - Flashes Blue After Plugging In Mini DisplayPort Adapter

Mar 1, 2010

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.

IMac :: Switch Between Displayport Inputs / Using External Display Screen?

Mar 17, 2009

I have a MacBook Pro. I see that the new iMacs have a mini displayport input so that the 27" screen can be used with my MacBook Pro. I'm wondering how this works? Since there is obviously no button to push, how exactly do you switch between the iMac and the MacBook Pro displaying on-screen?

OS X V10.7 Lion :: System Unresponsive After Coming Back From Sleep

Mar 29, 2012

I leave my imac on at night, from screensaver it goes to a black screen but I have selected that the hard drive never goes to sleep. In the morning when I click the mouse or a button on the keyboard it shows me a frozen screensaver screen and the imac is totally unresponsive. Have run disk utility and everything seems totally fine there. It is impossible to use the force quit option so have to resort to switching the whole thing off from the power button.

The software is all up to date and since disk utility shows everything in perfect working order I am puzzled what this is. A corrupt file or app? I am not a heavy user so no games installed - only software installed is the caffeine app, microsoft office for mac which is compatible with my imac, skype and that's all. Lots of free space on the hard drive too. I am not an expert on macs so I don't know how to look in case something in specific causes this that I can uninstall.

MacBook Pro :: Purple Haze On Screen - Mini Displayport Connected To VGA Adapter?

Jan 27, 2010

I just hooked the cable up, and I get the standard Purple Haze in space desktop that I have on my Macbook, but nothing else. No icons, no toolbars, nothing. The only time I was able to get anything to come up on my larger screen was when I went into Preferences, and Desktop and Screensaver. When I click on that, I did get a box to show up on my larger screen, listed as the Secondary Desktop.

How exactly do I get the larger screen to serve as my main screen? When I close up my laptop,the larger screen goes blank. I have no idea what to do, please help!

Another question I have is how the screen will look once I do actually get it to work. The reason why I ask that is because my larger screen is an old 17" Dell, the old 4:3 box kind. I plan on upgrading to a 20" plus HD display in the near future, but cannot at the moment, so the current 17" will have to do.

Anyhow, just curious if the screen is going to be completely wonky looking given the resolution that my Macbook will be feeding it?

OS X V10.5 Leopard :: IMac Screen Went Black - Starts Up With Black Display

May 24, 2012

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?

Mac Pro :: Using Mini Displayport To DVI, HDMI Or Displayport?

Oct 28, 2009

I have an ATI Radeon 4870HD graphics card which has a Mini Displayport and a Dual-Link DVI port.

I'm connecting this to two Dell U2410 which each have a Displayport, HDMI ,DVI and VGA ports.

I can connect one of the monitors straight to the DVI port, but what should I do with the other? I can't find a Mini Displayport to Displayport adapter for sale in the UK. But there are Mini Displayport to HDMI adapters and Mini Displayport to DVI adapters available.

Also, would it be best to have both monitors on the same connection? If i go the HDMI route should I buy a DVI to HDMI adapter for the other port? Or have both on DVI? Will there be a visible difference between the monitors if they're not on the same type of connection?
