HT4279 3 DVI Monitors on HD5770 Card

I want to run 3 DVI monitors from my HD 5770 card.  Can I ues the standard Apple Mini DVI to DVI Adapter or does it need to be the £70 Mini DisplayPort to Dual-Link DVI Adapter !

You need two active dvi adapters to drive three monitors on the 5x70 cards. 
Read these:
Mac Pro (Mid 2010), Mac Pro (Early 2009): Issues with three displays and multiple DVI, HDMI connections
Mac Pro (Early 2009), Mac Pro (Mid 2010): Supported display configurations
If any of them have resolutions less than 1920 x 1200 then you can use single link active adapters. The "AMD Eyefinity Validated Dongles" chart shows some active (and passive) adapters that are acceptable.  For example of a single link DVI active adapter is the Accell B087B-006B.  An example of a dual link DVI active adapter would be the one from monoprice.com if you need to connect monitors with a resolution greater than 1920 x 1200.
Here's a good explaination of what's going in here and why you need two active adapters on these cards:

  • 2 DVI Monitors and HDMI TV

    Hi there,
    I recently purchased a new 6 core mac pro with the standard Radeon 5770 card. I'd like to be able to hook up my two DVI monitors (Dell 2405FPW and SP2309W) as well as a Panasonic HDMI 32inch TV to it. I was wondering if this was possible.
    Had a live chat with "TECH SUPPORT" at monoprice.com, and they suggested I purchase the Mini DisplayPort to Dual-Link DVI Adapter, as well as the Mini DisplayPort to HDMI (with digital audio) adapter. I purchased the Apple version of the Dual Link adapter and monoprice's HDMI adapter.
    I hooked them all up, but am not able to use all three monitors simultaneously. I've read apple's support pages and have seen how you may need TWO Dual Link adapters for DVI displays. but...then how do I get the HDMI tv to work?
    Has anyone been able to do this.
    Thanks in advance.

    When using three displays with one card, all Mini DisplayPort adapters must be the active type. All dual-link DVI, VGA, and some single-link DVI adapters are active, but there don't seem to be any active Mini DisplayPort to HDMI adapters.
    You can use a DVI to HDMI adapter with the DVI port on the card, or with an active Mini DisplayPort to DVI adapter, but that won't provide audio over the HDMI link because there is no audio on DVI. You can use a separate cable for audio, or use a special DVI to HDMI adapter that can add the audio from the Mac Pro's optical output to the HDMI link:

  • Dual DVI Monitor KVM

    Hi, I like to know if there is any one have experience using a dual DVI monitor kvm switch with Mac Pro successfully. I own a 'Uniclass' 2-port dual dvi kvm, so I can share the dual monitor with another Linux box. However, it works on the Linux box, but when I tried to switch to Mac Pro, all I can see it works just in the beginning before the OS X load, that is the grey apple and small spinning circle on primary monitor, then the monitor lost the signal.
    If you have successful story, can you let me know which brand of kvm you are using? Thanks in advance.

    I'm using a RATOC Systems switch with mine. It supports
    dual monitors but I only have one monitor so i only use it
    like that. The model I have doesn't seem to be available
    in the USA. Only Japan where I live. Here's a analogue
    switch that they make however. Two of these would probably
    work if you don't mind going throught the analogue 15pin
    conversion.
    http://web1.ratocsystems.com/english/products/subpages/RS-210c.html
    I guess since that page is one of the few offerend in English
    that it's available in the USA.
    My RATOC KVM is dual monitor / KB / Mouse / Line-in / Line-out
    for 4 PCs and cost about $150. Switchable either by a button
    on the KVM Box or by a KB HotKey sequence. Mine is made
    for PCs but it's working fine with the MacPro.

  • Portege R500: cannot connect the remote DVI monitor via Dynadock

    Hello,
    I just connected Dynadock (DVI) with my Portege R500. The notebook would be supported -- according to Toshiba -- but my experiment confirms that Dynadock is not able to access DVI port. This implies, that Dynadock is nothing more than USB HUB.
    My setup: Vista 32b Business (CZE edition), latest fixes, Toshiba R500.
    Software: latest dynadock software 2.3c.
    Symptom: I cannot connect to the remote DVI monitor via the dynadock, only two external panels with 800x600 are available, but Vista does not allow me to choose them.
    More info: Dynadock Software requires to run without Microsoft Defender, else it blocks service:DisplayLinkService; file:C:\Program Files\DisplayLink Core Software\DisplayLinkService.exe
    If you disable MSDef, the message "error 2738" appears when you connect the dynadock and when Vista tries to install a missing drivers for you.
    Yes, I do know the VBS issue, and the problem is not caused by VisualBasic -- VBS "Hello World" runs.
    If you still believe, that Toshiba Dynadock is compatible with Toshiba R500, then press Fn-F5 and peek at your logs and you must find something like:
    In English: igfxext.exe throws an exception 0xc000000d, offset 0x0000f9f8.
    I welcome any comments, hints etc. If you are able to pass this bug report to a responsible engineer, do so please.

    Hello again Leo
    I still believe you are wrong. Toshiba Dynadock is not designed for Toshiba products only. It is universal product and can be used on every notebook. To be honest I believe it is better to use it with new, more powerful, notebooks.
    When you sat your notebook model is listed as compatible I believe you. Why not? Toshiba can list all newer notebooks. No problem at all. To be honest I am also interested to buy Dynadock but after reading your posting I wanted to see how it works exactly.
    I have contacted my friend because he works in one big electronic store and I was lucky because he had Portege M500 too.
    He was very nice and offered me to test Portege M500 SSD model with Dynadck PA3542EY1PRP. I hope you have the same model. It is DVI model. So I have done follow:
    - Portege was preinstalled with clean Vista OS (factory settings started for the first time)
    - I have installed latest Dynadock Utilitiy for Vista 2.3c
    - Installing this software you must pay attention about installations steps and the installations procedure should not be interrupted
    at one step there is window Installation Complete but it is not complete and must be continued with
    Display Link Core Software installation
    Video Dock installation
    at this point the Dynadock must be connected to favorite USB port NOT FROM THE BEGINNING
    - At the end I have restarted notebook
    The installation was finished properly and I have connected 20 Toshiba Tekbright LCD display (DVI cable). The native resolution is 1680x1050. in Display properties there are shown three displays. Display number 3 belongs to display connected to the Dynadock.
    Resolution 1680x1050 was there and display shows perfect picture. I have tested it as extended desktop and it works without problems. I didnt test it playing some movies.
    I have also tested it with FN+F5 key combination. It does not work as it should be but there is definitely no error message. I know that FN+F5 key combination is not designed for external graphic card and I know that it can not work well.
    At the end I can sat that Dynadock works well with Portege M500 SSD and there is definitely no error message. It works with Vista very well. I have tested it with screen saver and with few restarts. Nothing changes. Everything was OK.
    So after this test I can say that you have done some mistake. If you want to use it again I recommend you to install Vista again using recovery image. After doing this you will have clean preinstalled OS. Install software but please follow the menu on the screen and be sure all three components are installed properly. If I am remembering well when you see message about USB audio device installation you must connect Dynadock and continue installation.
    PLEASE FOE DYNADOCK USE ALWAYS THE SAME USB PORT!!!
    Sorry for this long story but I can say for sure IT WORKS PROPERLY!!!
    Have a nice day!

  • Converting one of two DVI monitors to HDMI to view on HDTV

    Is this even possible?
    I have a DVI splitter already in place on the 2nd monitor but the DVI-to-HDMI converter next in the chain to the HDTV (1080p) keeps popping up the incompatible video signal message.
    Do I have to connect the optical audio line to make nice?

    Hi-
    The DVI splitter can only supply one resolution.
    Unless both monitors are of the same resolution, problems will result.
    Using both ports of the graphics card will give better results.
    If one port is ADC, use the ADC to DVI adapter (Belkin or Molex) to connect one DVI monitor,
    Use the DVI port to connect DVI to HDMI.
    Do I have to connect the optical audio line to make nice?
    No.
    You only need that to get audio.

  • Windows 8.1 update only hdmi monitor detected 2 dvi monitors undetected

    Updated Windows 8 to 8.1 and have 3 monitors on Geforce 660ti video card. Since update only hdmi monitor detects. Have updated all video card drivers and clean installed multiple times but still same problem. Can unplug hdmi monitor and get nothing. Plug
    it in and that monitor works but nothing on dvi monitors.

    Hi,
    Check whether the monitor is detected by the computer according to this method:
    Go to control panel, then go to hardware and sound, click the display.
    Then click Change display settings at the left panel, just like the picture shown as below, then click Detect.
    There should be all the monitors listed, meanwhile I suggest to go to the official website of your computer motherboard producer and download and install the BIOS version accordingly.

  • What adaptor do I need to connect from mini display port to a dvi monitor

    I want to connect a 2nd monitor to my mac mini via the mini display port, will the Apple adator do this ok or will I need an active adaptor

    I had trouble with different Mini DisplayPort to DVI adapters, including a couple of Apple branded ones.
    When I mentioned the problem to the Apple rep. at Fry's. He walked straight over to the rack, handed me a > Kanex Mini DisplayPort to DVI-D Adaper grined and said, I've never had one of these baby's come back.
    After that my 2010 Mac Mini has been very stable running Dual 21.5" Samsung DVI monitors. One in on the Apple Supplied HDMI to DVI adapter, the other now on the Kanex Adapter has been rock solid for over a year.

  • Does Mac Mini's HDMI-to-DVI cable support analog DVI monitors?

    The Apple website shows that the new (late 2012) Mac Mini comes with an HDMI-to-DVI adapter cable in the box :-)
    The DVI video connector standard supports both analog and digital video signal modes, but not all models support both modes.
    I have an old PC monitor with a DVI connector, which is probably analog only.  Will this work with the new (late 2012) Mac Mini?  
    In other words: does Apple's HDMI-to-DVI adapter cable support all DVI monitors, or only those with a digital input?
    Many thanks!
    - Martin

    Your right about the DVI standard support both analogue and digital. The three types are
    DVI-A (analogue only)
    DVI-D (digital only)
    DVI-I (supports both)
    In this case the HDMI to DVI adaptor will only support digital DVI. This is because the HDMI port only supports digital.
    Generally monitors with a DVI port support digital DVI, if you compare the socket and pins layout on the monitor to the one on the Mac adaptor if they are the same layout then that should indicate the monitor indeed supports digital DVI.
    Note: The maximum resolution supported by the Macs HDMI port is 1920x1200, if your monitor supports a higher resolution then you should get a Mini Displayport to DVI adaptor or if needed a Mini Displayport to Dual Link DVI adaptor (for the highest resolutions).

  • Don't setup an XServe with a DVI monitor if you intend to use a VGA monitor

    Hi Forum Folks.
    A bit of a "gotcha" to warn others about, with XServes, and VGA vs DVI monitors.
    We Recently re-setup (erase + install a fresh OS) on a 2008 XServe Xeon, with a DVI (Digital) monitor connected. All worked fine, and we went to move the server into the production environment.
    However, when we moved + plugged the XServe into it's new home (a rack), it would not boot (flashing question mark).
    Moving the Xserve out of the rack, and back to it's work-bench setup, made it work again.
    We traced the problem to the monitor we used... If we hooked up a digital (DVI) monitor, the XServe worked fine (with the mini DVI to DVI connector). If we hooked up a VGA monitor (with a mini DVI to VGA connector) that's when the XServe wouldn't boot. We tried a variety of common techniques to solve the problem, including resetting various settings, re-installing Mac OS X 10.5.6 Server over the top etc.
    The solution:
    (Although I'm sure there are simpler solutions):
    We setup the server again (from scratch) using the VGA monitor combination from the very start of the setup, and all worked fine (on VGA or DVI monitors). The server is happily in production now, with it's VGA output.
    So the lesson here: Always set up your XServe using a VGA-based monitor in the first instance.
    Hope this helps someone else.
    Cheers,
    Derek

    So the lesson here: Always set up your XServe using a VGA-based monitor in the first instance.
    ... or don't use a monitor at all
    I don't think I've ever used a monitor when setting up a server - maybe used a KVM if I've re-installed or upgraded the OS, but for the main part every install I do is run remotely.
    Still it's good to know, especially since it defies logic.

  • Can I use the Apple VGA to DVI adapter to connect a PC to a DVI monitor?

    Hi
    Any idea of the Apple VGA to DVI adapter would work to connect a PC's VGA output to a DVI monitor?
    Is it a simple pass through?  Or are there drivers needed.

    That adapter is for connecting a VGA display to a computer's DVI-I port.  A DVI-I port has both digital and analog video pins.  The adapter passes just the analog video to a VGA connector.  It will not work in the reverse direction because a VGA computer does not provide digital video.
    There are VGA to DVI converters that will connect a DVI display to a VGA computer.

  • Does any have a solution for supporting 2 DVI monitors on an Intel xServe

    Can anyone tell me how to configure two DVI monitors to a mid-2009 Apple xServe3.1 running OS X Server 10.5.8 that only has a miniDisplayPort?

    Before recommending using a PCI Express 2.0 video please identify any such solution with a manufacture and model identification of the adapter that will work with this series of Apple xServe. I.A.W. Apple reps. there no PCI Express video adapters that are available presently that will work with the Intel based xServe systems.

  • External DVI monitor not working with new iMac 27"

    I recently purchases a 27" iMac and i'm trying to get it working with a 3rd party DVI external monitor. I got the Apple mini display port (thunderbolt) to DVI adapter and connected everything via a new DVI-D cable. The iMac detects there is a monitor and even shows the display as it should.. however, the monitor has a large amount of static/snow/noise (red coloured), so much so that the monitor is unusable. There is also a considerable amount of flickering.
    The monitor works fine when connected to a Mac Mini with the Mini DVI - DVI adapter, (old set up) so I know the monitor's connection is not faulty.
    Also, the monitor connects fine to the iMac when using a mini display - VGA adapter. The problem really seems to be with the combonation of DVI cable and adapter.
    Has anyone had any experiences with DVI monitors connected to new iMacs via the thunderbolt port?
    (System: iMac 27" 2011, 3.4GHz i7, 16GB RAM, Graphics AMD Radeon HD 6970M 2GB. All system updates installed, running OSX 10.7.2)

    I think that your assessment is right, the ATI must be on for DVI to work (so far I've only tested with an older T61p and the Quadro graphics are always running).  Can't you set the machine so that when docked the ATI is used, but on battery the internal video is used? That would be what I would try.

  • Mac Mini does not detect DVI monitor on boot but does so on awake

    Hi,
    my Mac Mini fails to detect a monitor on the DVI port when it boots (monitor says no signal).
    If I leave it a few minutes to boot, then put it to sleep and awake using the power button, then the display appears.
    This problem does not occur with the DVI-to-VGA adapter, and I have tried with 2 separate DVI monitors (different brands) and cables (both monitors are fine with Windows PCs).
    I have tried various resolutions and color depths, to no avail.
    Any ideas about how to resolve this?

    What brand and model of monitor do you have?

  • Switch 2nd monitor  between dvi monitor and hdtv

    I have an Intel iMac and I use the mini-dvi output to have a second monitor for working on the computer and also to watch online videos on my hdtv. Both work great. The problem is I have to reach around the back of the iMac to unplug the dvi monitor and plug in the tv and then do it again when I want to get back to work. I am pretty sure that the mini-dvi socket is not built to be used twice a day or more, so I am eager to find a better solution (preferably cheap).

    I am using the apple mini-dvi to dvi adapter with a dvi-hdmi cable to connect to the visio 42" hdtv and the same apple mini-dvi adapter with a regular dvi cable to connect to the Sceptre 22" monitor. The TV is in the next room, so it is not really practical to use as a second monitor, besides sometimes my wife wants to watch TV while I am working.
    I think what i am going to do is get a small dvi extension cable and leave that connected to mini-dvi adapter which I will leave plugged into the iMac. That way I will just be plugging and unplugging into the dvi extension cable (which is more robust than the mini plug) which will be much easier than reaching blindly behind the iMac. If the extension wears out I can just get a new one rather than having to get the iMac repaired.
