Single DVI to Dual DVI

I own a 23" Apple clear-plastic-case display with an ADC connection. I also own an Apple DVI to ADC converter. Is it possible to use some sort of adapter to vonnect my display to a Dual DVI connection? Thanks.

When you take the Apple DVI-to-ADC connector (with power supply) and attach it to your ADC display, it converts your display into a DVI display with a power supply "brick" in the cable. ANY DVI computer output (Single-Link or Dual-Link, or adapted from something else) can be used to power your new hybrid DVI display, since it 1920 wide or less.

Monitor does not come out of sleep Mac-Mini Mini-DVI to Dual DVI-D cable

I have an August 2009 Mac-Mini that I'm using with an Apple supplied Mini-DVI to DVI adapter along with a DVI-D Dual Link Cable connect to a Sceptre X7XV-Naga+ LCD monitor.
The monitor is going into sleep mode on its own with no way to disable this feature on the monitor itself. I've disabled sleep mode on the Mac-Mini in the power setting in System Preferences.
When in sleep mode and I move the mouse or press a key, the monitor will not come out of sleep mode. From other posts, I read that the issue might be that I wasn't using a Dual-Link DVI-D cable, so I bought one and installed such a cable. That has not resolved the problem. The monitor will not come out of sleep mode. When I have the monitor connected with a mini-display port to VGA adapter instead of a DVI-D cable, it will come out of sleep mode every time.

I know it's a year later, but I'm not finding much through search.
I have the same exact problem. Difference being I'm using an iMac with 10.7.5.
Same video board and monitor - ATI Radeon HD 6750M video card connected via DisplayPort to Samsing S24A850DW.
I've tried two different mini-DisplayPort to DisplayPort cables and no change.
I think I read that 10.8.3 might fix the issue. Anyone that can confirm that, or has another solution?

DVI-D Dual link and DVI-D Single link

I have here a FPD2185W Gateway 21" monitor that will not connect to my mac via the MBP's DVI port. I sent in the Mac for repair and it was sent back saying "everything is A-OK". Now my question is, are the cables that i am using effecting the functionality because i know the monitor works on a PC via DVI, but not the mac. The Cable im using now is a DVI-D Dual Link cable. would it be wise to try the Single link cable? I am pretty sure i have tried everything, and am desperate to get a DVI signal going to my monitor instead of the VGA.
-thanks, grant

Do a Google search on "FPD2185W Mac" and you'll see quite a few problem reports. It seems like the Gateway display is the problem and just won't work properly with some Macs.

Mini DisplayPort to DVI-D Dual Cable/Adapter for mid-2010 iMac?

Hi . . .
Sorry to pester with a question that's been covered from various angles before, but I'm new to the Mac world. Am a musician in BC, Canada doing a project remotely with people in Ontario. Decided to ditch my PC-based recording rig and went with a 2010 iMac and Logic Pro X (hallelujah!) because the other people are using Logic Pro X. So . . . I'm just learning the ropes.
Anyway . . . I have a spare monitor I want to run in dual setup extended desktop, and I'm not 100% certain of the cable and/or adapter I'll need. I'm also not sure why the adapters are bigger and seem to contain more internal components, whereas the cables just look like a simple "Plug 1" connected to "Plug 2" cable in a variety of lengths (in the same way you'd have a XLR to 1/4" phono cable).
Here's the info on my system, and any help would be greatly appreciated (will a cable suffice or do I need an separate adapter, DVI type, etc).
My iMac (mid-2010 21" Core i3 with Firewire running Moutain Lion 10.8.5):
http://www.everymac.com/systems/apple/imac/specs/imac-core-i3-3.06-21-inch-alumi num-mid-2010-specs.html
My monitor I want use as an extended desktop (Acer 22" X223W LCD):
http://reviews.cnet.com/lcd-monitors/acer-x223w-lcd-monitor/4507-3174_7-32627876 .html
So, it appears I'll need a male Mini DisplayPort to a male DVI-D Dual adapter and/or cable. Do I need to specifically buy a DVI-D Dual cable? Will a simple cable function properly or do I also need an adapter? I'm pretty sure a DVI-I cable won't work because it would have extra pins that aren't present in the DVI-D.
Thanks again . . . the assistance is appreciated.

You are overthinking this.
"DVI dual link support" is concerned about the resolution of the display, not the number of displays.   A dual-link adapter or cable basically has double the number of wires to carry extra data to support higher resolutions than a single-link cable. Of course, both the computer and the external display must also support the higher resolutions in order to take advantage of the capabilities of dual-link.
You want to use two displays ... your iMac's buit-in display + your Acer display as a second monitor (what you called "dual monitors"). You can do this, as I explained earlier.
Your Acer monitor's maxiumum resolution of 1680 x 1050 is not high enough to require a dual-link connection.
"In single-link mode, the maximum pixel clock frequency is 165 MHz that supports a maximum resolution of 2.75 megapixels (including blanking interval) at 60 Hz refresh. For practical purposes, this allows a maximum 16:9 screen resolution of 1920 × 1080 at 60 Hz (1915 × 1436 at a 4:3 ratio).
To support higher-resolution display devices, the DVI specification contains a provision for dual link. Dual-link DVI doubles the number of TMDS pairs, effectively doubling the video bandwidth. As a result, higher resolutions up to 2560 × 1600 are supported at 60 Hz [via dual-link DVI]."   (See Digital Visual Interface, Wikipedia)
You can connect almost any VGA, DVI or HDMI display to your iMac, using the appropriate cable and/or adapter. Of course, you always have to make sure that your cable has the correct gender plug on each end.   The Apple adapter I recommended has a female connector, so you will need a cable with a male DVI-D plug on one end. As for the other end of the cable, check the input on your Acer display to see what it has and select a cable that has an appropriate gender connector on the end that will plug into your Acer monitor.
In extended desktop mode, you can set separate (independent) resolutions for your iMac display and your external Acer display, taking advantage of the maximum resolution of each.   (For example, that's why the MacBookPro example you cited works, it's because that model MacBook Pro can support higher resolutions on an external display than it's built-in LCD panel can.)

No Video from Mini-DisplayPort or DVI, only Dual-Link DVI

Just got my new Mac Pro 6-Core delivered. Out of the box, there were problems. I have a Dell 27" monitor that takes Dual-Link DVI, DisplayPort, or HDMI and a Dell 22" monitor that takes DVI, VGA, or HDMI. I am using a DisplayPort to Mini-DisplayPort cable to connect my 27" monitor to the Mac Pro and a DVI cable for my 22" monitor. I have the ATI 5870 graphics card installed OEM.
The problem is that the graphics card appears to not be switching to Mini-DisplayPort or DVI for output. It only works when I plug in a Dual-Link DVI cable to my 27" monitor. At that point, I get a video feed on my screen on a hard boot. At this point, I can then plug in my Mini-DisplayPort cable to my Mac Pro and unplug the Dual-Link DVI cable, and it switches video feeds perfectly. The problem then is that when I restart the computer, or power off and power on, the problem starts all over again. I HAVE to boot using the Dual-Link DVI cable for anything to work.
Ideas? Called AppleCare, waiting on engineering to see what they have to say. All the cables work perfectly when I plug them into my MacBook Pro (Late 2008). I am stumped.

I seem to be having similar problems. I bought the same system (6-core Westmere with the 5870 graphic card installed OEM) last month and I seem to be having problems running two Dell monitors which I know to be perfectly fine.
For the past month, I've been using a 24" Dell U2410 monitor with my Mac Pro using a DVI cable. Absolutely no problems at all. I then purchased another 24" Dell U2410 with the intention of running with dual displays. To prepare for this, I bought two mini-DisplayPort to DisplayPort cables from Monoprice. When I finally received the second display, I turned off the computer, hooked up both monitors through DisplayPort using the two mini-DisplayPort connections on the graphics card and turned on the system. I got two black screens. I tried to use keyboard commands to bring up the shutdown dialog box but it wasn't working. So I was forced to do a hard shutdown by holding down the power button for 10 seconds.
I went through a series of combinations of power cycles for the displays and computer and still two black screens. Finally, I went back to square one, a single display through a DVI cable. Again, a black screen. At this point, I disconnected the display from the computer. Power cycled the display (this initiates the self-test for the Dell display), hooked it up to the Mac Pro, turned it on, and it worked. I had one working display. Then I plugged in the second display using the mini-DisplayPort to Display port cable and that worked also. Finally, two working displays. For some reason, the Mac Pro recognized the display using the DisplayPort as the primary monitor. I rebooted the Mac Pro and the monitors continued to work properly. I booted into Windows 7 and again, no problems. I went back to OS X and used the computer for the night. When I was done, it put it to sleep.
This morning, when I tried to wake it up, same problems. I had to go through a series of power cycles and cable swapping to finally get a single screen to work.
I went through some of the troubleshooting documents here in the Support area and found this one:
http://support.apple.com/kb/HT4279
I am going to pick up the Apple mini-DisplayPort to DVI adapter and try running the display as two DVI monitors. Hopefully this will fix those problems. If the AppleCare engineer is able to give you anymore information, please let us know. This is a worrisome issue.

T420 can't use dual DVI connected monitors

I have a T420 connected to The ThinkPad Mini Dock Plus Series 3 - 90W (433810U* - United States), DVI port 1 connected to monitor and VGA connected to second monitor using extended desktop. This configuration works fine but when I hook up both DVI ports to my monitors only one of the screens work and in the Intel Graphics and Media Control Panel only shows one monitor. I have 2 different cables 1 DVI-D dual-link and 1 DVI-D single link, the dual-link works with the VGA setup but with the 2 DVI connections only the monitor with the single link cable works.
Any ideas?
Thanks

No display when connect DVI-D dual link cable

Hi
I am using MS-6398 motherboard and I have the latest Bios 5.60. when I connect DVI-D dual link cable from ATI All-In-Wonder 8500DV graphic card to my SONY SDM-M81 Flat Panel. There is no display at all during POST as well as after boot up. It has display only if I connect with regular analog VGA cable. I have contacted the ATI tech support and they ask me to contact the manufacturer of my motherboard because it don't have display during POST which is nothing to do with driver.
thanks,
Siong

DVI-D port on the Ultradock is single link only.
If you need DVI-D at dual link resolution (i.e. 2560x1600), you need an active displayport to dual link converter. Startech makes them, they should be around 80 USD or something of that region.

Thunderbolt hub with dvi-d dual-link, daisy chain that isn't too expensive?

I've been following a number of thunderbolt hub progress for 2 years now, and STILL can't find one that I need.
UTTERLY MUST HAVE dual dvi. This means a minimum resolution of 2560x1440, which is what my current 27" IPS monitor does.
UTTERLY MUST HAVE gigabit ethernet. Wireless N does not cut it.
Really nice to have a daisy chain so I can hook it to my thunderbolt external drive, but not critical.
NICE TO HAVE a power out so I can power my MBA from it, e.g. have two cords - thunderbolt + power, so I don't have to carry a spare power adaptor to the office.
Basically what I've been seeing is either DVI single, or hdmi, or no daisy chain, or no video at all.
Here's things I've looked at that DON'T cut it:

Oh, and just to pre-empt the guy who who inevitably suggest that I just buy a new apple display (as if they are worth throwaway money): NOT AN AFFORDABLE SOLUTION, please just move on.

I don't believe that a product exists that meets all your requirements, though it's possible I've missed something. Probably the only way you'd get even the primary two requirements is to get an expansion chassis and add the appropriate PCI cards, and that's not going to be cheap.

Dual DVI Monitors at Aluminum MacBook 13"

Hi,
I want to buy a 24-inch display and I am wondering if I can use it with this setup:
1.
Macbook 5,1 (Aluminum, late 2008)
with NVIDIA GeForce 9400M
and Mini DisplayPort
and Mini DisplayPort to DVI Adapter
2.
ViewSonic 20-inch with DVI-D input 1600x1200@60Hz
3.
Some 24-inch with 1920x1200
Do I need another Adapter to use both Displays, the 24-inch and the 20-inch?
Do I need another Adapter to use only the 24-inch, without the 20-inch?
What ports would be best for the yet to be bought 24-inch? DisplayPort?
Thanks in advance for your replies!

You don't need Apple's dual-link DVI adapter, in fact I would avoid that adapter unless you really need it (because of its cost and for compatibility reasons). Since all of the displays you plan on connecting to run at 1920x1200 or less you only need standard (single-link) DVI. Dual-link doesn't allow you to connect simultaneously to two displays, it just supports higher resolutions (anything beyond 1920x1200).
Here is a link that describes the differences between single-link and dual-link DVI:
http://www.datapro.net/techinfo/dvi_info.html
If you need to drive two external displays simultaneously you probably want one of the third-party dual-head adapters. Here is a link to one such product:
http://www.matrox.com/graphics/en/products/gxm/dh2go/
There are also USB-based display drivers (as the previous post noted), but you may find the performance of those products somewhat lacking.

ATI Radeon 9600 Pro 256MB 8x Dual (DVI/DVI) (AGP) Video Card for PC/Mac

We want to be able to use our 30" cinema display from the G4 and was advised in a previous discussion to buy the ATI Radeon 9600 Pro 256MB 8x Dual (DVI/DVI) (AGP) Video Card for PC/Mac. It doesn't seem to be available anywhere. Does anybody know of an alternate video card that's currently available that will get us there? (We had the display running from a G5 that quit / logic board failure).
Many thanks,
Philip

The Nvidia 7800GS is a flashed card, runs a 30" with ease.
BruinMacs on Ebay is a great place to get one, you support the guy who wrote the original ROM for these.
He doesn't seem to have any for sale right now, but if you email him, maybe he will list one.
There are also flashed X800s that work on your MDD and can run a 30". They are pricey but will offer dual DVI while the 7800GS is single DVI with VGA for second display.
There are also flashed 6600GT AGP cards which will work, but harder to find.
Any of the above 3 will run circles around a 9600.

Help Connect my Mid-2009 Macbook Pro to my new YAMAKASI CATLEAP Q270 SE 27" LED 2560X1440 WQHD DVI-D Dual Computer Monitor

Hi,
I am trying to connect my Mid-2009 Macbook Pro to my new YAMAKASI CATLEAP Q270 SE 27" LED 2560X1440 WQHD DVI-D Dual Computer Monitor. I am not having a lot of luck.
My machine:
OS: Mac OS X Lion 10.7.4 (11E53)
Graphics Card: NVIDIA GeForce 9400M 256 MB
Processor: 2.53 GHz Intel Core 2 Duo
I am trying to connect it using the:
Mini DisplayPort to Dual-Link DVI Adapter
DVD-D HDMI cable

Here is what is happening.
1. I connect the Mini DisplayPort to Dual-Link DVI Adapter + HDMI Cable to Monitor
2. Main monitor powers up like it is trying to display
3. Laptop Monitor displays second part of desktop
4. I can never get the Yamakasi to display a picture
Here is what I have tried:
1. Different HDMI-D cables
2. ATLONA AT-DP400 Dual Link DVI to Mini Display Port Converter
3. Zapping the P-Ram
4. Powering monitor with laptop closed
5. Forcing the system to see the second monitor
The nearest I can figure:
- The laptop does see the catsleap (it displays resolutions I can set it to)
I am completely stumped, I was hoping someone could advise me.
Thanks,
Don

Hey Kytarx,
I found the winning combination this weekend.
I tried:
- Apple Mini DisplayPort to Dual-Link DVI Adapter
- ATLONA AT-DP400 Dual Link DVI to Mini Display Port Converter
- Monoprice Mini DisplayPort | Thunderbolt® to HDMI®, DVI & DisplayPort Adapter
My experience:
- Altona didn't work at all, and their support claimed it would not.
- Monoprice didn't work to Dual DVI, it did work to HDMI (great price I wish it did)
- Apple Mini Displayport adapter did work, but would only work with certain USB + Display port combos.
The thing that was tripping me up was that two of the Dual DVI-D cords were bad. Once I found the working cord, it was easier to find the working adapter. The experience I did find to be a frustrating / expensive one. However, the Monitor itself is beautiful.
Hopefully this helps someone else..
Don

You could just add an adapter, though not everyone is happy with that, for your 2nd port on the GT120.
Could wait for Nvidia eVGA GTX 285 Mac Edition next month.
http://eshop.macsales.com/item/EGVA/01GP31080TR/
There is/was and should be 8800GT with nice specs and dual monitor support.

Dual-DVI Adapter and Windows 7

Just under a month ago we have purchased a new mac mini that's running Windows 7. Mac mini is now connected to a 29" UltraWide AOC Display using a Dual-DVI link adapter. Everything is working okay in terms of resolution, but the screen cannot detect input after Windows 7 boot screen.
When you first switch on the mac, you get the Windows start up and then it goes to a black screen. The monitor displays no signal on DVI and goes to standby. We have to unplug the DVI adapter from the thunderbolt port and plug it back in, for the monitor to come back on.
Any ideas what could be wrong? Do we need a special driver for the adapter?

As previously stated mount # and chroot in the install grub to /dev/sda mbr - nothing will be lost from your hdd and grub will boot in preference to winloader
Use the the beginners guide for the commands and adapt for your system
https://wiki.archlinux.org/index.php/Be … ase_system
https://wiki.archlinux.org/index.php/Be … bootloader
... and always install windows first - if you did a clean windows install it may be best to install all the service packs / major updates before bothering to reinstate grub as you may find you need to repeat the process anyway

Does 785GM-E51 DVI support dual link?

I am considering buying the 785GM-E51 motherboard which comes with a DVI port (as well as HDMI and VGA of course).
Will the DVI support dual link? If so, what is the maximum resolution I could have on the two monitors (say, at 60 Hz with high colour depth)?
Cheers!
jcarrete

Please clarify your question, dual link has nothing to do with being able to use two displays.
"Dual-link should not be confused with dual display (also called dual head), which describes those situations where a computer is hooked up to two monitors at once. "
That quote from here: http://en.wikipedia.org/wiki/Digital_Visual_Interface
That been said I think you should be able to have 2 displays, 1 DVI or HDMI + VGA You can't have 2 digital out at the same time though, DVI + HDMI.
