HT4279 2 DVI displays on my 2 weeks old macpro,

I connected 2 DVI displays to my MacPro the graphicscard only sees the one that's connected with a DVI cable not the one connected to the mini displayport.
Does anyone know how to solve this problem?
I have 2 minidisplayports and it doesn't work on either one.

There is/was a nice article on rules on resolution and what you need, but sounds like you need the dual-link DVI adapter to use MDP.

How to use thunderbolt port with disks and DVI-display

Hello,
today I use a 15" MacBookPro and have attached 1TB LaCie with FW800 (for time machine) and DVI-Display using Mini-port.
Need to add more external disk space and look for Lacie 2 TB with thunderbolt connection (for storing mass of pictures in Raid1 version)
Is it possible to connect the new disk, the other disk with an Thunderbolt->FW800 adapter and the DVI-Display to one thunderbolt port?
What are the options I have, to get all three to work at the same time?

No, or at least not without additional hardware. You have too many end-points for one Thunderbolt chain.
You also have the problem that the Thunderbolt->FW800 adapter is not yet for sale.
If the new disk you get has two Thunderbolt ports (which not all do), you could daisy-chain the Thunderbolt->FW800 adapter behind it, but that adapter has to be at the end of the chain. The Mini-port->DVI adapter likewise needs to be at the end of a chain.
So, you can probably get all three connected at one time by connecting the "1TB LaCie with FW800 (for time machine)" to your FW800 port, while connecting the Thunderbolt->FW800 adapter (when available) to the second port of the new disk. I say "probably" because nobody has the TB-FW adapter yet to try it.
As for doing it on one Thunderbolt port with additional hardware, you might look into third-party docking stations being released in the next few months. The announced prices are in the low-to-middle hundreds. I won't mention brand names, as this is an Apple forum, but they aren't too hard to find by web search.
The highest-priced solution would be the Apple Thunderbolt Display, which gives you a FW800 port for your 1TB drive, a pass-thru Thunderbolt port for your new disk, and of course a 2560x1440 display (plus ethernet and usb2 ports you may not need). It's available now, in the uppermost hundreds. There are some refurbs in the online Apple Store at the moment at 15% off.

2 External DVI Displays on MacBook Pro Retina Display

Hello,
I have seen all the 3 external display setups for the RMBP and all that stuff going around the internet showing how thunderbolt displays and HDMI can be used together.
I have also read about how daisychaining works for 2 apple thunderbolt displays.
But i was wondering if i can use two external displays on my retina MBP buy using a mini DP to DVI converter. Then attaching a DVI splitter to this converter and connecting the two ends of the DVI splitter to 2 DVI displays.
This is setup we use at my work. The splitter is nothing fancy. It connects to the dvi output on our PC computers and we connect it to our two monitors. to get dual displays.
Or will this not work and I will have to use both my thunderbolt ports to run 2 mini DP to DVI converters? (slash will that work?)
Advice will be very much appreciated!

You can, but you need additional hardware to do so:

Extending my desktop across 2 (DVI) displays from 15" MacBook Pro Retina

Hi. I bought a new 15" MacBook Pro Retina a few days ago and am trying to connect 2 Dell displays with a view to extending my desktop across them both. At the Apple shop I was told I simply needed to buy 2 Thunderbolt to DVI converters (my 2 displays both have DVI out) and hook them up... Not true. If I try this my desktop only extended across 1 display. The other display isn't even picked up by my MacBook Pro.
So does anyone out there know how I connect 2 DVI displays to my MacBook Pro without buying a Matrox Dual Link? If I bought an HDMI to DVI converter cable and connected one display via the HDMI port, and the other display via the thunderbolt port, would this work?

May not be an upgrade issue ..
You have a fast processor. and 8GB of RAM is more than sufficient. (The processor cannot be replaced)
Click your Apple menu  top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space. Less can slow the system down.
If your Mac seems to running slower, try the suggestions here > Mac troubleshooting: What to do when your computer is too slow | Macworld
If you have not done so, especially with school files stored on the hard drive, make sure to back up your important data on a timely basis. Help here > Mac Basics: Time Machine
Not a good idea to post the serial number of your Mac on the net. I have asked the moderators to edit that information for you. It has nothing to do with upgrading.

Make sure the mini-displayport/TB plug is fully seated. It may look fully plugged in but isn't.
Make sure the Displays system preferences has an Arrangement tab. No Arrangement means the monitor is not being detected.
Do a smc reset.
If none of this works I suggest you take it back to apple (along with your mini).

HT5918 how to connect 6 DVI Displays to MacPro

Apple states can connect up to 6 DVI displays to a MacPro explanation is not clear. Mixes Mini-Display and USB terminology. What does it mean?

The article you linked to includes:
Mac Pro supports a total of two single-link DVI displays. If you connect a third DVI display using a passive adapter or a display via HDMI, it will cause one of the three displays to become inactive.
Can I connect more than 2 DVI or HDMI displays?
Mac Pro supports a total of two DVI or HDMI displays when connected via the built-in HDMI port or using the Apple Mini DisplayPort to DVI adapter. To connect additional DVI displays, use an active DVI adapter such as the Apple Mini DisplayPort to Dual-Link DVI adapter. You can connect up to six active adapter DVI displays. This requires a powered USB hub since Mac Pro offers four USB ports and you will need six to connect them all.
If your display are 1080p pr less they you can use 2 standard/passive mini displayport to DVI adapters and 4 active mini displayport to DVI adapters. If 1080p or less you do not need the dual-link adapter which are active. Yo can get less expensive active adopters.
If any of your display are greater than 1080p you need the dual-link adapter. Those included a connection to USB for power. These cost about $100 each for the Apple branded ones

DVI display port/ADC display port bottleneck!

My G5 dual came with ONE DVI display port and ONE ADC display port. I wish to add another monitor for editing purposes. My current monitor is an NEC multi-sync, which uses up the DVI port...leaving the ADC port empty and useless.
1. Am I forced to purchase an Apple Cinema Display?
2. Would it be more frugal to purchase another video card?
3. Can I make this work even though I have bought every 'adaptor' under the sun and the ADC port is still useless?
4. It there a 3d party adaptor that can use the ADC port to use an NTSC (television) device as 2nd monitor?
thanx

Hey U-dog,
I went to see Mr. Whooppee at Dr. Botts and ordered the shiny new DVI Extractor II (sounds like I'm back in the hackin biz) and again, I'll hold Sweet Polly or Breezly bruin hostage if this (last attempt at adaptors[sold for g-4s]) DOGgone thang don't work. So keep an eye out at WDOG or the local tundra if you REALLY care about those toons!
fingers crossed,
wallet still full
shoes shined,
parka on
night gogggles on, (it stays dark up there)
traps baited with prime rib bones (outside WDOG)

2013 X1 Carbon says no DVI display when trying to boot up

Not sure if this question should be here or not. It's about Thunderbolt ands DVI displays.

On the Thunderbolt info page on the main Apple site, it states that it is possible to put a Thunderbolt Display in the same daisy chain as an Apple LED. How about 2 DVI displays?
The displays in question would be a Viewsonic VX2433wm (currently running off a MacbookPro) and one of 2 Viewsonic VG2230wm's I have collecting dust. Will they continue collecting dust? 8-/

Let me amend that if I may. To focus the question a bit: I'm about to drop the hammer on the purchase of a new Mac. I'm a pro photographer and my current set-up is the 2007 Core 2 Duo MacBookPro with the VX2433 external monitor mentioned above and all my storage (and Time Machine) is/are (?) on a variety of USB and Firewire drives totaling about 12 Tb. So the system is pretty modular. I don't really use the mobile aspect of the laptop much anymore with an iPad for presentations, so I'd like a little more horsepower than a new MacbookPro but I don't want to break the bank doing it. I guess the one thing I am trying to retain is having 2 screens, because that has allowed me to become spoiled in Photoshop (and shhhh, Lightroom) where I keep most of the palettes on the laptop screen and the work on the calibrated external monitor. So what I was thinking about is a Mac Mini with the faster 2.6Ghz quad i7, the 1Tb Fusion Drive, max'd out to 16Gb of RAM and additionally a Superdrive and wireless track and keys (cuz I wore mine out and am limping on 3rd Party crap). All of that would be $1,666 and probably a pretty kickin' machine for the price I think
But now that I've read a little more, it looks like I would need to get a Thunderbolt Display and run a DVI monitor with the included DVI to HDMI adaptor. OR IS there a way to run two DVI displays on the HDMI. There's a sentence on the Mac Mini info pages that implies there is, but it's kind of ambiguous. So clarification of thes issues could help me pull the purchase trigger ASAP - cuz the shooting biz marches on daily! ;-)

2 Week old 17 MBP not displaying video

Hello,
I am a tech support guy, and web developer, at a higher ed University. Anyway, I just recently got a new MacBook Pro about 1.5 weeks ago. It was a 17 inch MacBook Pro, 2.33GHz Intel Core 2 Duo, 2 GB RAM, 200 GB drive.
Yesterday, for no reason it would not display any video. I could use ctrl+command power and hear the HD making noise but the video would not display. Every 10 minutes or so I would see a flicker and see my desktop picture for a half second. I did research on the apple support area and I ended up reinstalling the OS thinking it was a software issue... something about high CPU usage being the problem. I doubted that was the problem, but I took the hour to reinstall from the 2 DVDs. It worked during the boot from the CD, so I thought that maybe it was the software thing. After doing updates I tested it and it worked, I put it to sleep and put it away. I pulled it out tonight and it worked for an hour then I downloaded one of my old excel files from online and as I clicked on the excel file my screen, as best I can describe started to look like it was dithering... then it faded to black. It did the flickering for a few minutes, then just black... yet again, no video. I could restart and restart and try everything and all I would see is a flicker and a flash of video every few minutes.
At this point, what do I do? It was not even two weeks old and I do have AppleCare. I installed Parallels and VirtuaDesktops, Office and Adobe CS3 and pretty much everything else was normal software. None of that was running or open when all of this happened, besides maybe Office starting to launch.
I hate to send it back if it is just a software issue but I can't keep reinstalling the OS.

I will try. However, I am now seeing no video... not even after I reboot it and hear a chime and the hard drive spin... nothing. The screen is black but doesn't appear to be all of the way black. It is black but not the same as when the computer is off, there is a hint of a little light at the bottom of the display.
I wouldn't think that VirtuaDesktops would effect the computer that early in the restart, but I will try.
I deal with hundreds of Macs here at work and this is the first time I have seen something that has caused so much problems out of the gate.

Conect a Cinema DVI display on my VGA device

Hello guys,
I have a VGA output in my video board and need to connect the cinema DVI display on it. Is it possible? Is there an adapter or conversor for this purpose? My video board doesnt have VGI output, only VGA...
Help please!!

HELP! - Same problem. CinemaHD (connected via thunderbolt/miniDisplay-adapter to DVI) works but the arrow can't find the target. It seams the calibration is incorrect. I found out that the position of the arrow should be one textline above the target. Than it works. Problem exists in all Monitor-modes. When Montors are synchronized You can see the arrow standing right on the target on Retina-Display while the arrow on cinemaHD is located somewhere else above it.
I can't work this way! Is there a patch? Please help me!

New DVI-standard doesn't fit with old Apple adapter

I bought a new MBP i7 the last week and was very surprised when i noticed that the adapter i bought (Mini Display to DVI) doesn't fit with my old adapter (DVI to VGA). Apples new DVI-adapter us the DVI-D standard and that doesn't work well with teh DVI-I standard. When i talked with Apple and also with a Apple store they didn't know of any new DVI-standard and if there is an adapter (Mini Display to DVI-I). http://www.interfacebus.com/DesignConnector_Digital_Visual_Interface_DVIBus.html
Is there anyone out there who know if it is possible to buy this Mini Display to DVI-I (Dual)?

The Apple Mini-Displayport-to-DVI adapter is DVI-D because there is no analog signal emitted from the Mini-Displayport. The contacts the adapter lacks are the ones that would carry an analog signal, if there were any. If you want to connect your MBP to a device with a VGA input port, get a mini-displayport-to-VGA adapter.

Does Your Exchange Calendar Currently Show Events More Than 2 Weeks Old?

Quick question: Can you view any exchange calendar items on your Pre which you have created on your desktop and which are more than two weeks old as you read this post? I can't. After several hours of support chat and then an "elevation" to phone support, I was told by Palm telephone support that this was a new feature after Webos 1.2.1.
However, two things make me doubt that this is true:
1) Other Pre users on precentral.net report that they have installed 1.2.1 and they can still see exchange calendar events older than two weeks.
2) I noticed something really weird: I had deleted my exchange account and was re-adding it in an attempt to solve the problem. The account was syncing but I was watching my screen and it was displaying the monthly view of September, 2009. When the account was almost done syncing, I saw the calendar "flicker" a couple of times and when it did, I could see that there were all my grayed out September dates. Then it said that sync was complete and all events before 9/30/09 disappeared.
SO...I'm thinking that the data is actually in the phone but just not displaying on the calendar! That is really weird and would seem to be a true "bug" to me. For my job, I really need to be able to look back and verify what appointments occurred on what dates in the past. The Iphone and Blackberry users at my office that use the same exchange server can look back months and years at their old events.
If you are reading this could you please reply to let me know if this is a unique issue for me or whether others are having the same experience? I'd really appreciate it.
Thanks,
Joe

Very similar issue here. I am syncing my Pre with Google Mail. Don't even ASK what a hassle it was to get my Entourage contacts into Gmail and have everything populate the correct fields. A freakin' NIGHTMARE.
That said, the syncing with synergy seems to work well, with one major drawback. No calendar entries older than two months. This renders my calendar virtually useless. What is the POINT of this stupidity. I am perfectly capable of deciding if I want to use my pre's storage for older entries.
Unbelievable. I really hope palm gets it's head in gear and starts supporting its loyal users. Much more of this, and I will jump to virtually ANY other smart phone.

I'm trying to share files from my old MacBook - I'm thinking I don't have the proper version of iTunes. How do I determine the version on my new iPad 2 - 2 weeks old?

I downloaded iFlashdriveHD, but the appropriate skins don't display. App asserts I must have iTunes ver. 9.1 or later. How do I determine what I have on a two week old iPad?
Just trying to do USB transfers from my black MacBook.

App asserts I must have iTunes ver. 9.1 or later.
Where are you seeing this?
The app is not telling you that you need 9.1 on your iPad.
It does not use iTunes on the iPad for anything.
I'm trying to figure the version on my iPad.
It is the version that comes with your specific iOS firmware version.
But again, it is irrelevant to the app.
If you just got the iPad, it (the iPad) requires iTunes 10.4 on your computer.
