Nothing displays using mini-DisplayPort on xserve?

I connected a VGA monitor via a VGA>mini DisplayPort adapter (from Best Buy) and I cannot get anything to display on the monitor? I even tried rebooting the Xserve. Any ideas as what might be the issue? Nothing is flashing on the System Identifier lights.
Thanks!

Hello Dreifort
For issues with no video, the article below can help continue your troubleshooting. I would try resetting the NVRAM and SMC as well as starting up in Safe Mode. Some other things to try is different cables for the display or try the adapter on another Mac.

Trouble with 30" HD Cinema Display using Mini DisplayPort to DVI Adapter

I bought a new MacBook Pro and I am having trouble getting the full resolution to work with my 30" HD Cinema Display (purchased in 2007 max resolution 2560 x 1600) using a Mini DisplayPort to DVI Adapter.
According to the specs page, http://support.apple.com/kb/SP581 , the max resolution of the HD external display is supported. Unfortunately the max that I can set it to is: 1280 x 800
Has anyone else had the same issue?
If this isn't resolved I'm likely going to exchange my MacBook Pro for one that can support this display.

So I went and bought the Mini DisplayPort To Dual-Link DVI Adapter as suggested and it seems to work great.
Now the problem that I have is when I open up Apple's DVD player, the screen is blank but I can still hear audio.
If I unplug the display, the movie will display properly. Rebooting with the display plugged in doesn't help either. I also deleted all the DVD players enc setting files so that they would re-initialize but no luck.
Any idea what this problem might be??

HT3913 Can I connect a Sony TV 32 inch to my late 2009 iMac as an external display using Mini DisplayPort to HDMI?

Seems doable--can I?

Hello, All-
I too am very interested in the answer to this query. Same set up, same fail w/the Thunderbolt cable. The Genius Bar at the Apple Store was no help & recommended I bring my 27" iMac into the store...seriously? Their ultimate answer was that I needed a plain old male-male mini display port cable....that the Thunderbolt cable was the problem. Bloody unlikely, I say. Another guy in the store agreed with me this morning, so swapped out the cable. I was hoping upon hope it was a bad cable, but no such luck—still nothing. Next I tried a mini-display-port-to-DVI adapter—DVI cable—mini-display-port-to-DVI adapter. This also did not work. Is there a chance that the iMac running Snow Leopard and the MacBook running Mountain Lion is the problem???

Thunderbolt display: devices not discovered after using Mini DisplayPort–to–VGA adapter

I have an interested problem related to using my MacBook Air in clamshell (closed) mode, connected to a Thunderbolt display. The problem appears to be related to moving my MacBook air between my office and my home.
At the office, I use the MacBook Air with an external VGA display, connected via the Mini DisplayPort–to–VGA adapter. At home, I use the MacBook Air together with a Thunderbolt display. An Apple USB keyboard is also connected to the display.
Mini DisplayPort–to–VGA adapter implicated
The following sequence of events causes the problem to occur:
Use the MacBook air (open) together with a VGA display, connected via a Mini DisplayPort–to–VGA adapter (depicted at right);
Put the MacBook Air to sleep by closing the lid, and disconnect the Mini DisplayPort–to–VGA adapter (I am not sure if the order of these two steps is significant—I usually perform them almost simultaneously when packing up my MacBook Air and getting ready to leave the office); and
With the MacBook Air still closed, connect it to a Thunderbolt display with a connected USB keyboard.
At this point, I would expect to be able to wake up the MacBook Air by tapping on the space bar of the keyboard. However, what I have observed is that this does not wake the MacBook Air.
I can wake the MacBook however by moving or clicking a Bluetooth mouse that is paired with the MacBook Air.
At this point, although the MacBook Air is awake, and the display is working, the USB keyboard connected to the display still does not work. This is the problem, in a nutshell.
Unplugging the USB keyboard from the display, and plugging it back in causes the MacBook Air properly to identify the keyboard.
I used Apple System Profiler to save a list of identified devices at two points in time:
Immediately after waking the MacBook Air by moving the Bluetooth mouse (at which point the USB keyboard was not working); and
After unplugging and plugging in again the USB keyboard (at which point the USB keyboard worked fine).
Many devices are enumerated in the second list that are missing from the first. For example:
Keyboard Hub@fe110000 <class IOUSBHubDevice, id 0x1000378ef, !registered, !matched, inactive, busy 3 (37993 ms), retain 6>
AppleUSBHub <class AppleUSBHub, id 0x1000378f2, !registered, !matched, inactive, busy 1 (37987 ms), retain 6>
IOUSBInterface@0 <class IOUSBInterface, id 0x1000378f4, !registered, !matched, inactive, busy 1 (37986 ms), retain 6>
Keyboard Hub@fe110000 <class IOUSBHubDevice, id 0x1000378f6, registered, matched, active, busy 0 (7 ms), retain 10>
AppleUSBHub <class AppleUSBHub, id 0x1000378f9, registered, matched, active, busy 0 (1 ms), retain 9>
IOUSBInterface@0 <class IOUSBInterface, id 0x1000378fb, !registered, !matched, active, busy 0, retain 7>
Apple Keyboard@fe112000 <class IOUSBDevice, id 0x1000378fd, registered, matched, active, busy 0 (112 ms), retain 11>
and many child devices…
Using the Mini DisplayPort–to–VGA adapter appears to be a necessary step to causing this problem to occur. If I merely disconnect the MacBook Air from the display, let it go to sleep, and then reconnect it again, the USB keyboard will work immediately and can be used to wake the computer from sleep.
Some devices are discovered even when the computer is in sleep mode. This is how it should work.
The problem appears to be that when a Mini DisplayPort–to–VGA adapter has been used since the last time the computer was connected to a Thunderbolt display, the MacBook air does not discover devices completely when it is again connected to the Thunderbolt display while in sleep mode.
Can anyone else reproduce this problem?

Hi glraczon.support,
It sounds like the external display you are using (projector) operates at a smaller resolution than your MacBook Pro. You may want to configure the display preferences in System Preferences for the external projector.
Here is an article that may help you with that process:

New iMAC to Dell 3008 using Mini DisplayPort to Dual-Link DVI Adapter

I just brought the new iMAC 27" iCore7. Previously I was using old MBP with dual link DVI to DELL 3008 and they did fine.
But Today I connect the Dell 3008 to my new iMAC using Mini DisplayPort to Dual-Link DVI Adapter...They could not work properly...
The dell shows images in red with flickers....
I've contacted the phone for help...and they said nothing could be done????!!!!!
Anyone could help??
THX

just update my progress...
I had made calls to Apple technical support center in HONG KONG for help...
To my surprise...they even did not understand what I was saying(Or just pretending...)....One interesting guy said I could take the new iMAC back to service center to change the 4850 display card to older version...or call DELL for help!!!!!
Fuxking Apple technical support center in HONG KONG
I was almost hopeless until I found a minidisplay port to display port cable in Circuit Assembly:
http://estore.circuitassembly.com/products/Mini-Displayport-to-Displayport-Adapt er-Cable.html
ONLY $14.95 !!
They sent the cable to me in 3 days time...and I hooked it up right away when I received it today...my Dell 3008 could display 2560 x 1600 normally again!!!!!
The problem is: Apple is still selling its FUNCTIONLESS Mini DisplayPort to Dual-Link DVI Adapter at high costing....sounds like cheating others....
What' s wrong with the Apple nowadays???

MacBook suddenly won't detect my display, Using Mini Display Port to VGA?

MacBook suddenly won't detect my display, Using Mini Display Port to VGA?

dohdoh1985, I have the exact same problem also! I recently bought a 42" RCA LCD TV. I connected my MacBook Pro to my TV using a Dynex Mini DisplayPort to HDMI adapter that I got from BestBuy. It worked great until I upgraded to Mac OS 10.6.4 and then it suddenly stopped working. Same TV, same settings, same cables, same adapter. Nothing changed since the last time it worked except that my OS was upgraded to 10.6.4, so i am assuming that is the culprit. The symptoms are EXACTLY the same as what dohdoh1985 described; when I plug in the TV, the laptop display flashes (3 times) as though it is detecting an external display and the picture on the TV briefly goes from blue to black for about 1 second then back to blue. The TV does not appear in the display menu / control panel and there is no sign that the MacBook detected it. I went through the usual troubleshooting steps (reset PRAM, checked connections, tv settings, etc) but nothing worked. Other HDMI sources (i.e. Blu-ray player) work fine on the TV using the same HDMI cable on the same port so there is nothing wrong with the cable, the TV or the TV's input settings.
Meanwhile, I can still connect my MacBook to my external ViewSonic monitor at work without any problems. It's just the TV that's not working.
I cancelled my cable subscription a while ago since I only watch shows online nowadays and this was my only way of watching TV shows, so I'm quite upset.
Apple, please help!

Mac is not connecting to TV after using Mini DisplayPort to HDMI Adapter Cable?

Macbook Pro is not connecting to TV after using Mini DisplayPort to HDMI Adapter Cable. 2010 Macbook Pro, just purchased Mini DisplayPort to HDMI Adapter Cable from Amazon. Link here: http://www.amazon.com/Mini_Dis-HDMI-CB6-Mini-DisplayPort-Adapter-Cable/dp/B003OC 6LWM/ref=sr_1_2?ie=UTF8&qid=1406238976&sr=8-2&keywords=mac+to+tv --When i connect both ends of the cable to the TV and to the laptop, the screen will blink, but then afterwards it will not mirror on the TV. I have tried going to display setting but cannot find the arrangements tab. When i searched "arrangements" a message said, "The Arrangement tab of Displays preferences is hidden because you only have a single display attached to this computer." Not sure how to fix this problem. I have connected this laptop to a TV before, but with a different cable other than the one i just purchased. Any help would be greatly appreciated, thanks.

Found the fix. Still don't know if it was Windows, iTunes, or Norton 360, but this worked immediately for me:

Re: iTunes Store Won't Load, Won't Show Error Message
Aug 13, 2011 4:32 PM (in response to Daedalme)
I found a solution posted from Rodfromnework for PC users. It worked for me and easy to do.
Start --> Programs --> Accessories (Right Click on Command Prompt) --> Run as Administrator
then type in:
Netsh winsock reset
Hit enter, restart PC, open iTunes, go to Store
Hope it works for you too.

My VGA output using Mini DisplayPort to VGA doesn't work.

Since I upgraded to Mavericks, my VGA output using Mini DisplayPort to VGA doesn't work. When I was using Mountain Lion, as soon as you plugged in the Mini adaopter into the mini display port, the screen would shrink and format to where it would project via a RGB cable to a projector. No such luck since Mavericks! Also, I had a lot of trouble with the DVD player when I tried to play a DVD and project it via a projector. It all worked seamlessly with Mountain Lion. Can anyone help me?

I think if you go to System Preferences >> Displays and Option-click on the "Scaled" radio button, it will show you all of the resolutions that you would have had before under Mountain Lion. I just upgraded to Maverick and my resolution preferences (mirrored on a TV using the Mini DisplayPort to VGA adapter, using 1280x768) were completely reset (my display was no longer mirrored, and the resolution on my main iMac screen became 2560x1440). I found my answer here: https://discussions.apple.com/message/23599645#23599645. Hope that helps.

I have a Samsung Laptop but would like to use Cinema Display with mini displayport. Is that possible?

I have a Samsung Lap top but would like to use Cinema Display. The only connections on my lap top is HDMI and VGA. How can I get it to work?

Thanks Malcolm. I saw this on the apple site
Kanex C247D Single-Link DVI to Mini DisplayPort Converter
Will that work?
I also spoke to someone at apple..They told me to get 2 cables. Mini DisplayPort to Dvi and Dvi to Hdmi..Connect the 2 and it will work...Do you think it will work? Just to save$$$

Use Mini DisplayPort to DVI adapter to connect Mac Mini to Cinema Display?

Hi
I have a new-to-me current model Mac Mini and want to use it with my 20" Cinema Display (model A1081).
The Mac Mini instructions say to use the HDMI port on the Mac Mini with a DVI>HDMI adapter cable. I seem to have only a DVI>Mini DisplayPort adapter cable. I'm guessing this will be OK to use, but don't want to fry the system straight out the box
Can anyone confirm it's OK to use DVI>Mini DisplayPort connection to drive the display?
TIA
Jim

Thanks for the reassurance BSteely!
One thing I've seen when rummaging through the forum is a suggestion that with MDP>DVI adapter is problems with display waking from sleep. Short of setting it not to sleep, is there a workaround to wake it up again if it doesn't respond to usual stimuli?
TIA
Jim

17" MacBook Pro to 30" HD Display issue using Mini DisplayPort to Dual-Link DVI Adaptor.

Just replaced the Western Digital hard drive on my MacBook Pro with a SSD now running Lion 10.8.2, (updating from Snow Leopard latest version).
I have a 30" HD Apple display monitor and very much love using it.
The issue.
The MacBook Pro will only allow the 30" Monitor to display its top resolution when the unit is closed, when it is open it shows either 2 screens or mirrored screens depending upon the settings, but not at the top resolution capable by the monitor.
Now, when I was using Snow Leopard on the previos hard drive, I could close the MacBook Pro and put the computer to sleep also putting the 30" Monitor to sleep, I could then wake the computer while it was closed with my external keyboard and the screen would wake showing the FULL resolution possible on the 30" Monitor.
Then I could open the lid of the MacBook Pro and the screen would stay black allowing ONLY the 30" HD Monitor to be used effectively as a desktop computer, without the complication or need to display 2 screens or mirrored screens but most importantly the fans wouldn't need to work overtime due to the MacBook Pro being closed cutting off vital ventilation through the 2 air ducts to the left and right of the keyboard.
For some reason I cannot do this with Mountain Lion, the compluter needs to be closed in order for the 30" Monitor to display top resolution, and the fans are working overtime and the unit is getting really hot.
My concern is that the MacBook Pro will overheat, the screen will be damaged as the MacBook does get exceptionally hot when running design and audio packages, even Adobe Flash sets the fans off, and lastly the computers speakers are muffled which is more of a moo point.
If anyone could shed some light or offer a solution I would be most appreciative.
My specs:
MacBook Pro 17" Mid 2009 3.06 Intel Core Duo, 8GB 1067 MHz DDR3, NVIDIA GeForce 9600M GT 512 MB, OS X 10.8.2 - connecting to an Apple 30" HD monitor with a Mini DisplayPort to Dual-Link DVI Adaptor.
Thanks

Thanks for your quick reply! I want to think I'm not technically challenged, but... are you saying to go from minidisplay on macbook directly to the firewire in the back of the monitor? Or should I try to attach it to that ugly bunch of cables at the end of the monitor cable (dvi, usb, firewire and the power adapter thingy)? Either way, it seems like I might need yet another cable? Like Mini-display to... ?
I feel like my mother asking these questions... At any rate, when I called the guy at apple support last time he acted like it was a Miracle that I had anything on my cinema display at all if I had a minidisplay cable plugged into the thunderbolt port. He said that didn't work (but obviously it did, at least a little) I DID get a picture, it just wouldn't display at the 2560x1600 resolution. More like 1680xsomething. fuzzy and big. I want my pretty picture back.
Thanks so much for your help.

External display via Mini DisplayPort to DVI no longer works with MacBook.

I had not used my external monitor in the last several weeks. I believe there have been a few OSX Lion updates since the last time I used the external monitor. I had installed all the updates prior to connecting my external monitor again. However, a few days ago I tried to connect the external monitor and all I get is a "No Signal" message on my external monitor. The Mini DisplayPort to HDMI works on my LCD TV, so I know the MDP works. I have also replaced the MDP-to-DVI cord and the external display still doesn't work.
I connected the external monitor to another computer running Snow Leopard and the external monitor works. So, the external monitor does work.
I have seen a few posts aboout this, but nobody seems to have a solution that works or is directly on point to my issue. I have tried to use all the scenarios for plugging in the external monitor and external monitor power. I tried to reboot the laptop with and withoout the external monitor connected. Same thing with the exteernal monitor plugged in and no power, etc. Nothing works. I have tried to repeatedly turn the external monitor on and off while connected to the MacBook. Again, that doesn't work.
So, I am open to any help someone may have. Here is what I am running:
MacBook, Aluminum 13" Late 2008
OSX 10.7.3
NVIDIA GeForce 9400M

While we all have MacBooks in this forum most of us don’t run Lion. There's a Lion Support Community where everybody has Lion. You should also post this question there to increase your chances of getting an answer. Lion seems to have problems with external monitors. https://discussions.apple.com/community/mac_os/mac_os_x_v10.7_lion

13" MacBook Pro (Early 2011) doesn't detect display over mini DisplayPort HDMI adapter in Mountain Lion 10.8.2

Hi to all.
I have a problem connecting external display (Dell U2311H) to my 13" MacBook Pro (Early 2011).
I use Tecklink Mini DasplayPort to HDMI adapter (http://www.techlink.uk.com/products/wires_cables/wiresmedia/wiresmedia_media/wir esmedia_mini_displayport_plug_to_hdmi_plug), but since U2311H doesn't have HDMI input, I also use Manhattan DisplayPort to HDMI Adapter (http://www.manhattan-products.com/en-US/products/8101-displayport-adapter).
And nothing.
The display is not detected, no picture or even external monitor presence at all.
I even reset PRAM, and installed 10.8.2 Supplementary update.
I also plugged and unplugged all I could, with no luck.
As I can see on Apple discussion, it is a common problem with 2011 MacBook Pro's.
It seems like the problem is in Thundebolt port, it somehow does not work properly.
If anyone has solved such ploblem, please let me know.

In reply to my own post have to say appologies to Apple whose Thunderbold port I used to blame.
Shame on me)
So, what was my problem?
Guess what?
Manhattan DisplayPort to HDMI Adapter !
The point is it's actually do only what it said to do, converts DP to HDMI.
But I for some reason thought it can be used vice versa, to be HDMI to DP converter))
I was wrong.
I bought new one HDMI to DVI adapter and now I HAVE external display!
Thunderbolt works like a charm.
So I'm very satisfied now.

Using Mini DisplayPort to VGA Adapter to connect Macbook Pro (2009) for a presentation via projector.

When I connect my Macbook Pro (2009 model) using a Mini DisplayPort to VGA adapter to display a presentation via projector, only the top-left portion of what is displayed on my Macbook Pro's screen is displayed on the projector, as though I zoomed in on that portion of my screen. The projector is on and the adapter and the cable that connects the adapter to the projector machine is correctly connected. Any suggestions on how to fix this problem?

Using Mini DisplayPort to VGA adapter -- any settings on the Macbook Air I need to change?

Going into a meeting with my Macbook Air with Mini DisplayPort to VGA adapter, which will be connnected to a video projector on site. Never tried this setup before. Will this just work or do I need to adjust any video settings on my Macbook Air?
