OS X :: MBP Monitor Not Working

Sep 15, 2009

I have already read other threads that are similar... but not the same as this.

I have a 15" late 2007 MBP that has always worked great, until recently. (10.5.8) The screen was blank this morning. I closed the lid, but the computer did not enter sleep. I opened the lid, and still nothing. (I can still hear the fan working)

I held down the power key for 5 seconds and forced the computer to turn off, and then rebooted. The computer started up as per normal, but still no screen activity. I plugged into my TV - no output signal.

I close the lid again to attempt to sleep, but no sleep. The computer is still running, even with the lid closed. I open the lid, still the same.

After doing a bunch of different things over and over, the screen came back on!

I came back to the laptop later in the morning, and I had to spend 1/2 an hour repeating the above process all over again. There seems to be no logic in my process that gets the monitor working again.

Does anyone think this is a monitor problem, or possibly a latch problem? I've heard that the latch is an important part of the monitor...

(I did upgrade my hard drive myself about 6 months ago, but no problems since... until now.)

IMac :: Working As External Monitor?

Nov 14, 2009

Title says it all...how does the new iMac work as an external monitor? Is there a way to use it as a monitor without having to log in / load OS? Is there any delay as compared to a standard monitor? I'm just thinking long term as the iMac becomes long in the tooth and we move on to new machines. Can the iMac still be used as a quick turn on monitor or do you need to load up both machines (and do you need to rely on all parts functioning in the iMac, such as mobo, hard drive, etc. still working) to utilize it as a monitor)?

MacBook Pro :: External Monitor Not Working?

Mar 13, 2012

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?

Mac Mini :: Monitor Currently Not Working Through Display Port

Mar 5, 2009

Just a piece of info for those considering driving a 30 inch Monitor with the Mini: The mini-display port to Dual Link DVI adapter Apple is offering is not working. There are some other forums discussing this problem with the unibody Macbook pro. I've been using mine since Dec. At irregular intervals the screen becomes blurry (weird double lines all over), and the only thing that works is plugging back in or (more harmless if you have multiple projects up and don't want them to be scattered all over the screen) Control-Shift-Eject to put the display to sleep, then wake it back up after a few seconds with mouse or keyboard. This can be very annoying as sometimes one has to repeat it multiple times. Apple is aware of the problem, but has not come forward with a solution. I just don't want you guys to be disappointed in your new Mini with a capable graphics card...

OS X :: External Monitor Not Working Properly With Snow Leopard

Jan 17, 2010

Recently I installed the Snow Leopard OS on my Macbook Pro, previously I had 10.5 installed. However, now when I connect my Macbook to my flatscreen TV (Panasonic Plasma), using a mini display port cable to an HDMI cable, there's a black border around the edges of the picture. Before the Snow Leopard upgrade I was able to view the entire screen area of the Plasma TV, without any borders. The only thing I've done differently since then is install Snow Leopard. Does anyone know how I can fill the screen with image without using the zoom option on the TV screen, as the zoom cuts off some image at the top and bottom?

MacBook :: Not Working With Monitor (Apple Cinema Display)

Dec 31, 2010

I've been using my black macbook for several years with both my Apple Cinema Display and Panasonic TV with the Apple mini-dvi to dvi adapter, but today when I tried to hook my macbook up with the tv it didn't work. The Tv just showed a black picture and nothing happend when I un- and replugged the cable. I tried it on my ACD as well and the colors wasn't right on it. Some colors wasn't showing, eg red. Green and blue was OK. I'm suspecting the adapter to be the problem, 'cause I've tried everything (also in preferences) and been using this method for years! Any thoughts on the problem? Should I buy a new adapter or try something else?

Connection methods;
TV = mini-dvi to dvi, and dvi to hdmi
ACD = mini-dvi to dvi and dvi directly to the ACD

Windows On Mac :: Dual Monitor Not Working In XP (boot Camp)

Sep 14, 2006

By using boot camp, I finally managed to install XP on my Macbook Pro. I can extend the monitor but the problem is that the extended monitor is in Black&WHite and totally jagged/off centered. I tested the adater and the cable with other machine and they work fine, so definitely issue is not the cable and the adapter. I really need to use Dual monitor for some software that I use on XP, so this is really really important to me.... My MacbookPro is 2.16ghz with 2GB of RAM, and the video card is ATI Radeon X1600. Maybe I need to install different driver for the card? If anyone has done the same please please let me know exactly how you did it

I recently got a PowerMac G4. When I viewed it Everything was working. Upon me hooking it back up I noticed It was not getting any picture.

OS X :: Expose Hot Corners Not Working After Unplugging External Monitor

Mar 22, 2009

I use Expos�'s hot corners on my Al MB. I also use an external monitor at my desk. When I unplug the monitor to disconnect the laptop from being "docked" (as it were), I find that I can't use hot corners anymore. If I restart the Finder, that doesn't fix the issue. If I go to Expos� preferences, and change a hot corner preference (e.g., what gets done when one goes to the upper right corner), then things get fixed. But I really don't want to go to Sys. Prefs. each time I change monitors. Is there any other solution?

OS X :: Two Monitors Connected Via DVI To A Flashed XFX 4870 - One Monitor Is Not Working?

Apr 9, 2010

I have a new issue with my Mac Pro (3,1 - 2008), it just popped up (and I don't think it was caused by 10.6.3, I remember this working correctly after it was installed I have two monitors connected via DVI to a flashed XFX 4870. The 4870 has never given me any trouble.In the Energy Saver settings, I usually set the machine to never sleep, and the displays to sleep after 5 minutes. This used to work great, never had any trouble with it, ever. Now, the displays don't go to sleep after 5 minutes, they just stay on with a screensaver.

MacBook Pro :: External Monitor / Mini Displayport Stopped Working On MBP

Jun 29, 2009

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 com.apple..plist files, etc

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

None have worked even a bit!.. Also read lots of forum posts of similar problems, but I can't find a solution that works!

IMac :: Secondary Monitor Not Working - Only Shows Black Screen

Jun 10, 2010

24" iMac running 10.6.3 and having some issues all of the sudden with my secondary monitor. It detects the display and the monitor comes out of standby, but only shows a black screen. Tried it with another monitor to see if that was the issue but it's not. Seems as if the iMac is sending bad video signal out... Couldn't find anything similar on a quick google search so I thought I'd try here to see if anyone had any similar problems.

OS X V10.7 Lion :: External Monitor Suddenly Stopped Working At 2440x1440

Apr 23, 2012

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.

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

Oct 28, 2009

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).

Hardware :: Mini DisplayPort To DVI Adapter Not Working - Monitor Not Receiving Signals

Apr 29, 2010

So I've got a Macbook Air, a cheap 3d party miniDP to DVI dongle I just got from ebay that's connected to a DVI to VGA adapter which is in turn hooked up to an old-ish VGA monitor. The monitor isn't receiving any signals, so I'm wondering if I'm right in concluding that this setup isn't supposed to work?

MacBook Pro :: Monitor Display Not Working Fine / Horizontal Scan Lines And Black Out Occasionally

Jul 9, 2009

So I had a recently purchased 17" BTO with the 7200RPM drive that worked great, but with one issue - the display would have horizontal scan lines and black out occasionally. So I called up Apple and eventually managed to get a cross-ship set up(they let me hold on to my current unit, charge my credit card and send me a second brand new 17" unit as a replacement,and then refund me for the second 17" after I send back the defective unit).

Anyway, the replacement unit looks great, but with one issue - there's a very small light dent on the bottom panel(maybe about the size of a dime). I was annoyed but don't think this is worth having to exchange, since I could probably just unscrew the panel and pop it back into place.

However, what really got to me was the fact that my replacement unit was slightly louder than my original - my original is so silent that I can't even tell it's on. However, with my replacement unit, I can hear the hard drive spinning, which is slightly annoying.

Anyway, I proceeded to restore from a time machine backup and test my replacement unit when I noticed that it would occasionally get the hard drive click + beep + freeze issue that many others who have the 7200 RPM drive seem to be facing. It's extremely annoying, and more importantly I miss the complete silence of my older unit.

My question is, while I'm still in possession of both units(which both have the exact same specs, same 7200 RPM drive, etc.), should I simply just open both up and take the silent(good) hard drive from my old unit and put it into my new one?

The click+beep freeze issue is really pissing me off, and my old unit didn't suffer from it - it's just this replacement one(doesn't make any sense).Anyway, would notice if I switched the hard drive? Would I get screwed somehow? Do they keep track of the hard drive serials or something?

I really don't want to go through the pain of sending this back, especially considering that a LOT of people are suffering from this issue, and I don't want to end up with another defective drive. I'm sick and tired of games and just want a computer that WORKS.

MacBook :: Can't Make Monitor On Mini Display Port Primary Monitor?

Aug 18, 2010

I have a fresh install of Windows XP, service pack 2 on a boot camp partition on my macbook (13" first gen aluminum case) and a Apple LED Cinema Display attached to the mini display port.

I can't seem to make the Cinema Display the primary display (the "Use this device as the primary monitor" checkbox is always greyed out in the Display Property Settings tab). I also can't shut the macbook lid and continue to use it closed (with kb, mouse and monitor attached) like I would when booting OSX.

Is there some other way to make the Cinema Display the primary monitor, so I can leave the macbook closed when booting into Windows?

Hardware :: Powerbook With Broken Monitor - Force Boot To External Monitor?

Jan 31, 2010

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?

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.

Hardware :: Apple 2001 Studio Monitor - Fomac Monitor?

Jul 12, 2009

I have a macbook pro from 2007, and I just popped into a tagsale and picked up one 2001 Mac Studio Monitor and a 2001 Fomac Gallery monitor.. So I was hoping to use the monitors with my laptop because the small screen on this laptop is KILLING me, and i'm not yet prepared (financially) to get a powermac.. Paid $10 for both of them..

my issue right now is, the monitor's cable doesnt match the input on my compuer. I need a ACD DVI clip cable.. Now, i looked them up and the price is $100! Call me naive, but i had no clue a connector cable would ever cost that much..

So basically, I am curious if there was a different option to get this to work with my computer OR if there is a place to get a used or "extra" cable

Power Mac G5 :: Reset Monitor Resolution Supported By Monitor?

Nov 22, 2007

I have a G5 Quad with an Ati x1900 graphics card running into a 52" Samsung LCD. This was working fine through a dvi-vga adaptor until I switched the monitor resolution from 1920X1080 to 1360X768 which is not supported by the monitor .....blank screen. I plugged another 19" monitor into the other output on the card and both work fine but as soon as I remove the 19" the 52" reverts back to the unsupported mode. I have reset the pram and tried booting in safe mode but that did not help me. From bootup the 52" works fine until just before the login screen, then it switches resolution......blank screen. Would anyone know where these settings would be housed in OS 10.5.1 so I can modify (delete) them?

Information:
G5 Quad
Mac OS X (10.5.1)
