MacBook Pro :: Dell Monitor Not Working As External Display / Screen Goes Blank

I have a MacBook Pro 13 for portability to my classes at the university and a Dell 2209WA as an external monitor. One of the few good IPS monitors I could find around for cheap.

The monitor works fine in mirror mode with the MacBook Pro, but as an external display only it does not work. It attempts to wake up and then you see power savings mode again and the screen goes black as if there was no connection. Not sure what exactly the problem here is. Drivers?

The monitor works great with a Mac Mini I have and it works great in mirror but not in external display mode(the lid of the MacBook Pro closed). Anybody know of this issue? The cable is good and the MacBook Pro is not that old(a few weeks).

MacBook :: Dell External Monitor And Get Display?
The text looks a lot different from the Macbook's display. I got it to 1080p and stuff - and yes, it's showing the full 1080p. But how do I get the text to look more like the Mac's text? My Macbook display looks so much sharper. The text on the Dell looks very not isn't thick, etc.

MacBook Pro :: Unable To Get Display With Dell Monitor / Monitor Do Not Show Up In System Profile
I have a brand new 15" MacBook Pro, the DisplayPort to Dual Link adapter, and a Dell 3007WFP monitor. This monitor worked fine with my previous generation MacBook Pro. When I connect it with the Dual Link adapter, I get no signal to the monitor and the adapter and monitor do not show up in the System Profiler, so I have no idea what the adapter firmware is. I've tried this on a current generation 17" MacBook Pro too and get the same result. Has anyone else had this experience? Any fixes?

I've already exchanged the DisplayPort to Dual Link adaptor once and the new one does the exact same thing. The MacBook Pro works fine connected to a 24" Dell monitor with the standard DisplayPort to DVI adaptor.

Mac Pro :: Dell Monitor Not Working Through DVI Cable / Screen Looks Terrible
I've just plugged in my Dell monitor and doesn't work through the DVI cable only VGA with adaptor plus the screen looks terrible (type blocky and distorted). Optimum screen resolution is 1680 x 1050 but that isn't a preset option. Anybody any ideas on driver support for this from either Mac or Dell?

Also what the **** happened to the Firewire 400 slot, they've removed it!! What a drag is there an adaptor available I don't have a USB or 800 firewire cable.

Hardware :: Unable To Get Display / Dell Monitor Connected To Macbook Pro MINI Display
I hooked up my macbook pro to a mini display port to a dvi -> hdmi to my tv no problem. However, when I hooked up the mini display -> dell monitor, I get nothing. The screen is black. The weird thing is that my macbook pro recognizes that a second monitor is plugged in... it just won't display anything

I am attempting to use an external DVI monitor using the mini port port and the mini port DVI adapter sold by apple. However the screen display on the external monitor does not match the Mac book display. All I get is a color Mac opening screen with no icons.apparently there is more to getting an external monitor going then just plugging it in.

MacBook Pro :: Recognizes External Monitor But Only Display Black Screen
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.

MacBook Pro :: External Monitor Not Working Correctly - Change Screen Resolution
I recently bought an external monitor and just hooked it up. It worked right the first time, and I had the screens mirrored. I tried to change the screen resolution and it went wack. It will not pick up a steady signal on the external monitor or the macbook pro when connected. I do not regain signal to my macbook pro until I either unplug the external monitor or turn it off it works on my roommates macbook pro. I can't even change the resolution to get it back to how it was originally because the computer freezes up.

MacBook Pro :: Retina Can't Use External 30" Dell Display
I've connected my 30" Dell 3007WFP display to my Macbook Pro 15" Retina laptop with Apple's adapter for Thunderbolt to DVI-D Dual Link.  The display is only receiving Single Link instead of Dual Link, limiting the resolution to 1280x800 instead of 2560x1600. 

Has anyone else seen this problem?  On the forums at, a few other people have reported this issue.  One person there has reported that his adaptor (same model as I have) provided this display with Dual Link when connected to a Macbook Air but not when connected to the MBP Retina. If that's true, then it sounds like there's a defect in the MBP Retina. At the least, should I return the adapter until Apple makes some kind of a statement about whether this can be fixed?

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

MacBook Pro :: Black Screen After Waking Up From Sleep With Connected Dell Display?
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 :: Detects An External Monitor But No Display On The Monitor?
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.

Hardware :: Get A New Dell Monitor Or A Used Apple Display?
I am in the market for a new display. I was thinking about getting a new dell one, but then again I love the looks of the Apple studio and cinema displays. Do you think it would be a mistake to buy a used Apple display, so long as it is in good condition? I have about $150-200 to spend

OS X :: External Monitor / Mini Display Port Stopped Working On MBP?
I have a 15" unibody MBP bought in Nov '08.

Had been using the Mini Displayport > DVI adapter just fine with both HDTV and Dell monitor, BUT then all output has stopped completely!

No monitor is detected by the laptop (although the display does blink blue, as if it had detected it), tried different cables, different displays, using the Displayport firmware update, speaking to Apple, deleting the files, etc

Edit: it also doesn't work in XP on Bootcamp

MacBook Pro :: Sound Card Not Working / Screen Goes Blank?
First of all, I have a Unibody MBP 2.4 GHz from October 2008. Today my sound card died. Or half died. My left speaker doesn't work anymore, and the sound card must have fried my headphones too, because the right speaker in those also doesn't work anymore (with any ipod / computer).

But this is only one of the many problems I've had with my logic board. I've had my logic board replaced twice for graphical issues, and now I'm experiencing even more issues. Every once in a while, the top 1/4 of my screen flickers black for a couple milliseconds. This happens on only the 9400. But, when I'm playing games using the 9600, it will overheat and my screen will go black and the sound will start looping. To fix this, I have to manually adjust the fan speed before I start playing. And finally, I've had some USB problems too. Whenever I plug in a USB device into my computer, it doesn't get recognized, get powered on. NOTHING happens. I have to wiggle it around for a couple minutes to find the "sweet spot" where it will connect.

All of my problems have been with the logic board.I'm going into the apple store tomorrow. I'm pissed. I shouldn't need to get my logic board replaced every couple months.

Any suggestions? Should I ask for a new MBP all together? Should I just keep putting up with this BS? Anybody have any permanent solutions to any of the problems I've mentioned?

Hardware :: Preferably Dell Monitor That's As Good As Apple Cinema Display?
I'm deciding to buy myself a new mac pro coming around Jan-Feb and since mac pro's cost sooo much I'm cutting money on every corner; from buying only on amazon to using magazine coupons. The biggest money waster in my opinion is the 22' Led Cinema display apple sells. It costs around 900$ to buy an apple display which hasn't been updated for 3+ years when new Dell monitors of the same size (with camera installed and quality optional speakers) cost roughly about 400 max? I know apple displays are premium but extra 500 bucks is ridiculous.

Mac Mini :: Dell Monitor - Energy Preferences Set To Turn Display Off After 15 Minutes
I have my 09 mini connected to a Dell E177FP and I have the energy preferences set to turn the display off after 15 minutes. The problem is that the display never turns off. It just sits at the "check signal" screen as if it was not plugged into anything. How can I get the monitor to go into standby mode?

MacBook Pro :: 13 + LG W2240T - No External Monitor Display
Have a brand new MacBook Pro 13 and LG W2240T connected with the MiniDisplay-->DVI-D adaptor. When I plug in the adaptor the screen on the Macbook flashes, the LG immediately says "DVI-D Power Save Mode" and then goes black. When I click "Detect Displays" it shows that no external monitor is attached. If I unplug the connector the MacBook display flashes. I think the Macbook is seeing something but it isnt sending a signal to the display. If I unplug the cable from the monitor I get a general "check signal" message floating around the screen. Dont think it is a problem with the screen. I dont want to have to shell out another $30 for a MiniDisplay -->VGA adaptor and use an analogue signal with the beautiful new digital display.

MacBook Pro :: Turn Off Display When Using External Monitor?
I have just bought a Dell u2410 display and I wanna use it as the ONLY monitor for my MacBook Pro while still using the keyboard and touch pad on the MacBook. But how do I turn off the MacBook display? If I check "mirror display" the Dell gets all unsharp looking so doing that and turn down the brightness of the MBP doesn't seem to work. But if the displays aren't mirrored I get the menu bar on the Dell and the dock on the MacBook. How do I disable the MacBook Pro display? (I use minDisplay to DVI)

MacBook Pro :: External Monitor Display Blurry
When I hook up an external monitor to the DVI output, and use both the macbook screen, and the external, the display on the external is blurry, and not very sharp. However, when I close the macbook, and run it in clamshell mode, the external becomes very clear, and crisp (like it should). I never use dual monitors, so this really isn't a problem, but want to know if its normal. 2007 Macbook Pro, 2.4, 4 gig ram. Gforce 8600M GT

Hardware :: External Dell Monitor - SL Color Levels - Gamut
I am running a Dell S2209W on my 13" Macbook uBody, a pro without FW if you will. Anyway, not sure exactly what is bothering me but after a while, my eyes feel strained. I have calibrated it using the SL built in calibrator and while it is better than out of the box, I still feel eye strain. Anyone else using this monitor and are you happy? Any tricks to calibration levels? Or is this an issue with SL color levels, gamut, etc.? I am seriously considering going to the U2410 for height and tilt capability if nothing else.

MacBook Pro :: External Monitor Not Working?
I am trying to hook up an external monitor to my mid 2010 MBP. I used a Logiix mini display port to DVI, and then DVI over to the monitor.  The monitor is a Samsung Syncmaster EX2220. When I turn everything on the monitor says "check cable" which everything is brand new and I don't have spares on hand to try. My MBP screen flashes quickly like it does when I have hooked up other external devices, TV, or projector except nothing shows up on the other monitor. I have tried to change resolutions but again nothing, installed all updates, restarted both devices and reset PRAM. One other thing that I noticed is the monitor comes with a cd that has a windows device driver. I searched but could not find a mac device driver, yet on the monitor specific webpage it says its mac compatible. It appears to me that the monitor is simply not receiving any signal from the MBP?

MacBook Pro :: Making External Monitor Display Primary?
I'm thinking about replacing my 24" iMac with a 15" MacBook Pro, however I'd like to keep my 20" dell monitor and use it as the primary display for the MacBook Pro, is that possible? By primary I mean having the dock and everything else on it, with the built-in display being like an external display that I can use for extra space. Also, would the same be possible at all with my iMac?

MacBook Pro :: External Monitor Attached And Display Closed
I typed Mac Help about "to operate the portable computer with an external monitor attached and the display closed. When I close the display of my Mac Book or MacBookPro, the external monitor such as my 50" Plasma monitor or video projector would go black. I read the Help and it said and required the USB Mouse and Keyboard to close the Macbook display and put computer sleep. My question is will the Apple blue tooth or wireless keyboard and mice will work with out using the USB? Has any one try that? I am not sure if I should buy wired or wireless to operate this.

MacBook Pro :: Can Not Display External Monitor Under Bootcamp Windows XP?
I have got my new uMBP i7. It is gorgeous, super happy with it . Because I need to run several programs under Windows XP, I have installed Windows XP under Bootcamp. I used Winclone to migrate bootcamp partition from my old MBP to the i7.My problem is that when I linked my external monitor (20 inch ViewSonic) to uMBP using the Minidisplay-to-DIV adaptor from Apple, there is no display on my external monitor. I can set the external monitor as extension of main monitor under "Setting", but after the windows Ding/Done sound, there is nothing on my external monitor. Does anyone have experiences about fixing this problem?

Snow Leopard :: Macbook Display Not Detected - External Monitor Display Normal
For the most part, my Unibody MacBook Pro 17/10.6.4 handles external monitors perfectly. I can even switch between home and work, with different physical external display arrangements, and the Mac remembers and "just works". (Vista was frequently forgetting the arrangement and randomly switching the configuration around.)

But every once in a while, the macbook display stays dark, the external monitor works fine, and "Detect Displays" does nothing. If I wait a while, and then try "Detect Displays" again, sometimes it will just start working.

Hardware :: Mini Display Port To DVI Cable Produces Blurry Images On Dell 2407 Monitor
I have a new Macbook Air 13", 4GB RAM, 2.13Ghz, 256GB SSD.

I'm connecting the Macbook with the Apple Mini Displayport to DVI connector to a DVI cable to a Dell 2407 monitor with a resolution of 1920x1200. The resulting image is blurry. The fonts are blurry and drop shadows on the screen flicker quite badly. The resolution on my Macbook is indeed set to 1920x1200 to match my Dell 2407.

Does anyone know what the problem could be? Is the problem with the Mini Displayport to DVI adapter?

I know for a fact that the Dell LCD and the DVI cable work fine with my Windows 7 box. I have tried two different DVI cables as well.

MacBook Pro :: How To Turn Off The Builtin Display When Connected To An External Monitor
WITHOUT closing the lid, because i like using the touchpad. i know that you can turn the brightness all the way down, but sometimes windows from the main screen randomly open on the other display. and it also slows down performance. i want to turn off the 13" screen as if the lid was closed. that way, the mac doesn't even see it.

MacBook Pro :: Internal Monitor Not Turn On But External Display Works
I have seen people all over the internet saying that their MBP monitor would not turn on, but I have not seen my situation before. I used the computer a week ago (it's a work machine and I'm a part time intern) and both the external and internal monitor worked. I shut it down and when I came back the computer booted up to the external monitor but gave no video on the internal.

I shut down, removed the external monitor (connected by DVI cable) and rebooted. Nothing came up but when I connected the external again it worked fine. This had happened before, but when I shut down and rebooted without the cable connected it came back on immediately. I'm just hoping its not a bad graphics card or something that needs to go in for warranty.

MacBook Pro :: Default Resolution On External Monitor - Proper Display
I have my MacBook hooked up to an external monitor of 1920 x 1080 resolution. I don't use the MacBook screen at all. Every time I turn on my MacBook it displays on the external monitor as it should, but at the MacBook's 1280 x 800 resolution, which obviously looks nasty and stretched on the big monitor. I fix this by simply putting the Mac to sleep and pressing a key on my keyboard to wake it up again; and it loads in the proper resolution. Is there a way to make it display 1920 x 1080 on boot up without having to sleep and wake every single time? Keeping my MacBook in sleep mode when not in use isn't an option.

MacBook Pro :: Video Display Crashes When External Monitor Plugged In
My boss just gave me a MBP Core I7 2,66Ghz / 4GB Ram, model mid-2010 for the business. It is equipped with Nvidia GeForce GT330M as PCIe video card.If I plug an external monitor, I have, after some time between minutes or hours of work, a weird video problem, which obliged me to power off/on the MBP. Sometimes I even can see my mouse moving, but I can't do anything with it.If I do not use the external monitor I do not have problem.This type of problem appears around 3-4 times a day and make the MBP unusable, as I'm loosing the recent work each time the problem occurred.

Here is the extract of the console at the time of the crash :13/03/12 16:45:51, no supported helper partitions to update.13/03/12 16:47:29,000kernelNVDA(CopyEngine): Channel exception! exception type = 0x27 = CE0:
