OS X :: Unable To Show 10.6 Install On External Monitor / Grey Box On External Display With Black Bar
Feb 27, 2009
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.

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.
Info:
MacBook Pro (13-inch Early 2011), Mac OS X (10.7.4)

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 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.

Recently I connected my macbook air (bought it in 2011, now on Version 10.9.3) with a Panasonic TV (TX-32LM70F) via Thunderbolt to HDMI adapter. After I disconnected the external device, the macbook air's screen still worked normal, but when i restarted it, it was only flickering grey. Â
I found out that it actually boots normally and i can use it with an external monitor (in fact I am using it right now), but that the built-in macbook screen simply doesn't work anymore. Â
I tried to restart while connected and while disconnected to an external screen, I have reset the SMC Controller, I have reset the PRAM Controller, but it hasn't changed. Â
This is actually the second time something like this happenend (it was another external device i connected it to), and last time, about a few weeks ago, it just worked again after a few days for no reason, all i did was wait until all energy was gone from the battery and the reload it. So might it be a battery problem? Or is it some controller i don't know? It was the same phenomenon two times: connect to external monitor - disconnect - built-in screen still works - restart - built in screen only flickers grey - macbook still boots and works fine with the very external monitor that might have caused the problem.

I have a 28" inch display attached to newest version of Air. Works ok except when I have a full screen on plain dark grey background, then I see a waviness or flickering effect. Like the dark grey in Iphoto background. Other than this, the other colors seems ok. Pictures are fine, even when dark. Maybe there's a slight flickering with dark blue. Any explanations for this.
using mini display port to dvi. Tried with a friends dual link display, was a little different, but still unstable looking in dark grey when it fills the screen.
Could it be just what it takes to make this color, or the Hertz, which is 60. Other than this, no problem with the screen.

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 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 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 Macbook running Snow Leopard 10.6.2 and an external display. I use the external display as the primary display, which works fine but I would like to be able to have the macbook become the primary display once I unplug it from the monitor.

I'm trying to connect my rMBP13 (OS X 10.9.3) received a couple of weeks ago to my desk display (LG Flatron W2486L) through apple's DVI-mini display port adapter.
Here is the results:
The MBP freezes a couple of seconds (I guess normal) after plugging in the mini display connector in one of the thunderbolt ports, but nothing happen on the external display (no signal).
The MBP sees the display: from "system preferences>displays" I see the MBP sees the external display and recognises the model "W2486"; but it seems to me that the display doesn't see the MBP...Â
I've tried to restart the MBP, but with the same result.Â
(I've ben using the display through the DVI port with my old PC, so it works).Â

I know that the web have a lot of tips similar to this that i will ask, but i couldn't find no one exactly with what i want
I bought a new monitor, and mini-dvi adapter, an external keyboard and mouse to plug on my macbook
I would like to know how to turn off the macbook display without having to close it. I want to know that because if i don't close the macbook, both displays are on. If i close the macbook, the computer goes to sleep and then i press some keys on keyboard and the mac wake. In that point, if i open my macbook the display is turned off like i want. But i don't want to have to close the macbook all the time, and i don't want to leave the macbook closed because closed the temperature goes high.

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

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 anti-aliased...it isn't thick, etc.

Is there a tweak out there that will disable the internal display while using an external monitor WITHOUT having to first close the lid on my macbook because I just leave my macbook plugged in for weeks a couple feet away from my desk and it's become a hassle to first close the lid, then move my mouse, then open the lid for better ventilation. I just want to leave it open and disable the display!

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?

I plan to get a 13" 2.26ghz Macbook Pro, and I have a 20" external monitor with a 1680, 1050 resolution.
First thing, I've barely used OS X, let alone with an external monitor. How well does OS X handle it? Is it pretty simple, and can I set separate backgrounds for each display?
Secondly, will the GPU handle it alright, or will it be sluggish when I hook up the external? I'll mostly be using the 20" to do Photoshop work, with occasional video editing (though I have other computers available to do rendering on.)

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.

I finally did it... After a lifetime of Windows I've leapt from the Dark Side and am LOVING OSX... the combination of Spaces and Expose alone will save me countless hours!
I just got the VGA adapter to connect my spangly new MBP to the large monitor I used to use for my PC (no DVI capability on the large monitor, Acer x223w). Now however, I'm getting a strange and inconsistent problem:
If I connect all the cables and then power up, both my large monitor and the MBP screen appear slightly but infuriatingly blurry (see screenshot, left-hand side). If I power up MBP without connecting my large monitor and then 'hotplug' it (connecting the cable while everything is turned on), the blurryness is mostly cured - see screenshot right-hand side. The screenshot is from the same monitor in the two different states.

I'm looking to have a display hookup in my room for my Macbook Pro 15". I can't decide if i should get a 26" 720p HDTV with a pc input or a large lcd desktop display with a cable input to watch tv.
What are the pros/cons? Has anyone tried/preferred either? Any recommended monitors or hdtvs?

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?

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.

I have a MacBook Pro 15" and my father has 17", both 2007 model.
I bought a new Samsung XL2370 external monitor (1920 x 1080) for my notebook. When I connect it to the 17" model, it works fine and gives me the full picture.
However, when I connect it to my 15" MBP, even at 1920 x 1080, the display gets cropped on two sides with black bars.
If I change the resolution to 1680 x 1050, then the whole screen is filled. But if I put it to 1920 x 1080, this happens.

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.

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.

I have a 14'' iBook and recently bought an LG 19'' Widescreen monitor. I am testing a Dell 17'' on it right now before I open the LG one, but my problem is that the same screen shows on my ibook and the external. This isn't what I want. I have read you are supposed to be able to close the laptop and then it shifts to the external display but this is not working for me.
This is my goal:
Use my bluetooth keyboard full time
Have my ibook closed at all times
Have my external as my main display
How do I make this work?

My friend has a PowerBook G4 and he wants to connect it with an external 20" Apple Cinema display. His friend told him it was not possible to connect it, but I am not certain if this information is correct. He asked me to help advise him on this, but unfortunately I don't know enough about Apple hardware to give him the information he is looking for. I am wondering if anyone happens to know the answer on this.
