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.

I use MBP (late 2011). I find the hunderbolt port to be similar to the mini-display port of older mac. I wish to have another display, but not ready to spend $999 over a thunderbolt display from mac. So would like to know if a Mini-diaplay port converter from apple would help me connect a exernal display via the thunderbolt port?

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?

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...

My iMac is I think 2009 model. It comes with a mini-display port.Â
I have a Dell monitor which has a Display port input and I want to use it as a second monitor. The DVI input in the Dell monitor is taken up.Â
But how do I connect from the mini-display in the iMac to the Display port in Dell monitor ? Doesn't look like aplle sell this connector cable !Â

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

a way to extend the mini display port cable on the 24" monitor? I'm using it with a 2009 mac mini and want to put the mini in a cabinet which is too far for the standard connection. The USB easy, but I can't seem to find a solution for the display port.

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.

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.

I want to buy the 27" iMac - but only if I can use it as external monitor for my Lenovo laptop when working from home. A the Apple store in London they said that this is possible with a Belkin converter from hdmi to mini display port (with a USB power caple to turn it into an active signal). The laptop also has a displayport.

I know that my Mac-mini (mid-2010) is not supposed to have a Thunderbolt port but, it does. No question about that. Maybe it's a prototype or transitional config.

I purchased a mini display port to HDMI. I attached the HDMI end into the back of my TV in the HDMI input 2 section. Then I attached the other end of the mini display port into the back of my IMac desktop. Nothing is happening. I went online to follow directions which told me to go into my 'System Preferences', then click 'Display' and then click the 'Arrangements' tab that would appear. However no arrangements tab appears. Did I buy the right cord?Â

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

I bought 2 new Macbook Pro 13' , 2.9 Ghz Intel Core i7, with 8 Go 1600Mhz DDR3, Intel HD Graphics 4000 512 MB, Mac OS X Lion 10.7.4 (11E2617).Â
I have connected a Mini DisplayPort to VGA Adapter in order to show presentations on different LCD projectors but no image appear.Â
The external monitor is detected but no image is shown. I have tried to change the frequencies: parts of the screen appears but no a correct image. I have the same symptoms with the 2 Macbook Pro. Using old Macbook Pro with the same Mini DisplayPort to VGA Adapter, the slides are showns normally.Â
I make a test with a Mini DisplayPort to DVI Adapter and with a Mini DisplayPort to HDMI Adapter and everythings works correctly with both adapters. Â

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.

How many of you would like to see a HDMI Port? Why the miniDisplay port? Why not remove ethernet jack and miniDisplay port and replace it with a HDMI port. That way one HDMI cable feeds digital video AND audio. Am I the only one thinking of this?

I need to connect my 09' Mac Mini to my Yamaha RX-V2700 receiver which outputs to my Sony XBR HDTV. I know the mini has both mini-dvi to dvi and mini-dp to dvi or hdmi available via adapters. I was thinking to go with option 1 however I was wondering what is your opinions? Is mini-display port better over mini-dvi or are they the same? Audio will be carried over optical toslink.
Option 1:
Using mini-dvi adapter to dvi: Connect Dvi-Hdmi cable to receiver and output audio with toslink adapter.
Option 2:
Using mini-dp adapter to dvi or hdmi: Connect Dvi-Hdmi cable to receiver and output audio with toslink adapter.
