OS X :: External Monitor / Mini Display Port Stopped Working On MBP?

Jul 1, 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

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...

MacBook Air :: Doesn't Detect External Monitor Connected Through Mini Display Port To HDMI Adapter

Sep 8, 2014

I bought a MBA 13" last month and now I'm trying to connect an external monitor through a Mini Display Port-to-HDMI adapter and most of the times the display shows a message "No signal detected"...

I've tried all the possible combinations between the MAC and the Monitor but it would seem a random matter.

Info:
MacBook Air (13-inch Mid 2012), Mavericks 10.9.4

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?

MacBook Pro :: Display Port Stopped Working

Feb 27, 2010

I hooked my Macbook mini-display port up to my new Sony 32" TV and it worked fine for a month or so, but then it stopped working. Now when I plug it in the TV says there is "no signal" and the laptop doesn't detect the display. Nothing happens when I plug it in. I have tried two different HDMI chords, but only one mini display chord.

Mac Mini :: Ethernet Port Seems To Have Stopped Working?

Apr 16, 2010

I've been having an annoying problem lately. The ethernet port on my Mac Mini seems to have stopped working. It happened when I was switching routers. Most likely I just unplugged it from the old router, and into the new one. After that, no more connection, nothing changes when I plug something in.

As far as troubleshooting goes, I've plugged it into other ports, and into my MacBook Air (Just to get a Self assigned IP) and nothing works. I know these ports work with my other computers. I've reset the SMC and PRAM.It works in bootcamp so this makes me think it's not hardware. Any other suggestions?

MacBook :: Mini DVI Port Stopped Working?

Jun 25, 2014

I often watch movies streaming on the internet by connecting my Macbook to my television via my Mini DVI to S-video adaptor cable. Last week, however, it suddenly stopped working. The television can still detect the display, but the image is super distorted and moving in a static-ey way. I can only vaguely make out the icons on my desktop on the TV screen. I thought that perhaps my adaptor cable was at fault, so I bought a new one - but the problem remains. I have also tried resetting the PRAM, repairing the disc and permissions with Disc Utility, and cleaning the Mini DVI port. I am pretty certain that it is a hardware problem with the port itself.  One of the pins on my Mini DVI port looks like it could be out of place. It is kind of squished at the bottom of the port instead of laying flat like the others. I’m thinking that this might be the culprit. Is there a way to repair the port without having to replace the whole logic board? The Macbook in question is a 2008 Core 2 Duo running Lion.

PowerPC :: G4 Display (Brand New Monitor) Stopped Working

Aug 19, 2007

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. The Monitor was brand new so I did not figure it to be broken I checked the monitor on another computer and it worked great. From what I understand this is a common internal problem on the G4.

Intel Mac :: Thunderbolt With Mini Display Port Shows Monitor As Generic VGA

Mar 23, 2012

With my 'old' Intel iMac using a Display Port adapter, my 24" LG Monitor would be detected correctly and worked first time.With my new 2011 iMac 27 using a genuine Apple mini DisplayPort adapter plugged into the Thunderbolt port, this same monitor now shows up as a generic VGA monitor and the range of resolutions is severely reduced - basically it looks terrible.I've tried disconnecting the cable, reconnecting, using the second Thunderbolt, changing resolutions, detecting displays, showing displays in the menu bar. All with no success.

Anyone have any ideas?

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.

Mac Pro :: Mini Display Port Not Working At Resolutions Over 1600X1200?

Apr 15, 2009

Problem:

Apple Mini Display Port does NOT work at resolutions over 1600X1200 on NON Apple Cinema Displays.

That means if you own any other brand of monitor such as NEC, Lacie, etc. you will NOT get native resolution on your 24 inch monitor as it is stuck at a maximum resolution of 1600X1200.

This story was mentioned on "Macbreak Weekly" show 4-14-2009. I have since checked with a few people and it would indeed seem to be true at this point.

I REALLY hope a solution from Apple comes soon and this is not some new policy of theirs. If so, it may be the last Mac Pro I will or can ever own. The reason is I do a lot of 3D work with C4D, Vue, Modo and Photoshop CS4 so I MUST have a monitor like the high-end ones from Lacie that have 100% color gamut and Adobe RGB. I can NOT be tied down to an Apple Cinema display due to that work. At this time, it seems this means I would only get 1600X1200 resolution on that 24 inch monitor.

I am HIGHLY concerned by this. Has anyone else confirmed this too and if so what the heck is Apple thinking or better still going to do about it? I LOVE my Mac Pro but if they start forcing Apple displays on us then I won't be buying another Mac, it's just that simple.

Hardware :: Mini Display Port To DVI Cable Produces Blurry Images On Dell 2407 Monitor

Dec 24, 2010

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.

Mac Pro :: Mini Display Port To Dual Link DVI Adapter Not Working

Jul 5, 2009

6 weeks ago I bought a Mac Pro Dual Quad 2,66 with an ATI HD 4870 graphic adapter. System is OS X 10.5.7. I try to get an Eizo 30" display (SX 3031W) working with this configuration. Using the signal connector #1 on the Eizo , the display will show up to 2560x1600 resolution (as it should be) but after selecting this option will fall back to 1600x1200 pixel. I tried installing on the DVI plug of the card and also on the minidisplay-port using the "Mini Displayport to Dual Link DVI adapter" from Apple but up to now it does not work.

MacBook Pro :: Mini Display Port Not Working On DVI - I Or Non Fully Digital Displays

Jun 2, 2010

I finally upgraded from my 15" PowerBook 1.67 to the new 13" MacBook Pro 2.66. On the PowerBook I would usually run an external display using a single link DVI cable. I have read about the issues with the apple mini display adapters not working on DVI-I or non fully digital displays, but since I had been running the external via single link DVI (digital correct?) I figured that I wouldn't run into any problems. I did some troubleshooting with what I had and plugged my computer into my TV through the mini display adapter to a single link DVI to HDMI cable and all worked fine. Do you think that a dual link DVI cable could solve the problem connecting to my monitor? Or is my monitor flat out incabable? Third party adapter? Worst case I could just go VGA, though I don't want to. My monitor is a Sceptre x20.

OS X :: DVI-HDMI Connection To External Display Stopped Working?

Mar 10, 2010

I have a macbook pro from fall of 2007. So far it has worked perfectly and I've used it with an LG full hd LCD for about 1,5 years. I use a regular DVI - HDMI cable.About a month back it suddenly stopped working. The TV just tells me "No signal".I didn't change any settings or anything. The computer still recognizes when something is plugged in as the screen flicks blue and the displays icon in the menu bar lists the TV with correct model and resolution. And if I have spaces turned on it changes from 4 to 8 "screens".

I have tried everything from rebooting the computer to resetting P-RAM.
I got a new cable, no difference. However when I tried the TV with my friends MBP, it worked. So the problem is definetly in my computer, not in the TV or cable.My OS X is Version 10.5.8 Leopard.

Mac Pro :: 4870 Mini-Display Port With Standard Display Port Panel

Jul 8, 2009

For anyone wanting to use their Mini Display port connector on their 4870 with a panel that has the standard size display port connector, I've found a source for a cable that works perfectly. It has the mini display port on one end and a full size display port on the other. Cost $19 bucks shipped and works like a champ. The cable is nice and compact, thinner and more flexible than my DVI cable. I'm quite pleased! ( it's the little things.... )

Here is the cable I picked up: Mini Display Port to Display Port cable

MacBook Pro :: Mini-display Port Versus Mini-DVI Port

Mar 16, 2010

Relevant newbie to the mac world. I have a MBP late 2009. I bought a third party Mini display port to HDMI converter so I can hook the MBP to my 46" Samsung screen.

This works fine, no major issues here. However the picture is not great. I compared watching a standard definition TV show through the MBP then burnt it onto a DVD. The DVD (using the PS3 as my DVD drive, connected via HDMI) had superior quality than through the MBP.

Also the picture does not quite fill the screen. There is a small black border running all the way around the screen. Does not sound significant but when doing the same comparison as above, you notice the difference when via DVD the movie fills the screen. I have played around with the resolution settings. Those that fill the screen chop bits of the mac desktop off, so thats no good either.

So I am wondering why this is? Is it because the mini display port is not a DVI port, hence I am not getting true HD quality picture? How can I overcome this if at all. I'm thinking of getting a mac mini as a media hub/HTPC but want to ensure I dont encounter the same problems.

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).
