Is the 7800GTX 512 MB dual-link?

Hi, I would like to know whether the new MSI nVidia GeForce 7800 GTX has at least one dual-link DVI-D connector allowing the 2560x1600 resolution.
Thanks

Sorry,
The problem above is solved for me.
With thanks to Joseph.( See discussion Mac Mini 1 feb. 2013.)

TS3232 I have the mini DisplayPort to Dual-Link DVI Adapter firmware 1.03 and I still have screen flickering issues

I have the mini DisplayPort to Dual-Link DVI Adapter firmware 1.03 and I still have massive screen flickering issues on a Mac Mini 2012.
I am using a Dell 30" monitor (it's the Samsung screen just rebranded) connected to a WD 4TB Thunderbolt drive connected to the Mac Mini.
The screen is usable for the most part when I've just started the computer (although today I started having issues after a fresh restart) but if even just the screen goes to sleep, or the computer goes to sleep and I wake it later, I start to have massive flickering to black and occasionally to snow.
The effect seems to be more likely to arise when I'm on heavy graphics-intensive websites or programs (eg, Tumblr feed with lots of GIF images or working in Adobe Premiere), but once it starts shutting down those programs has no effect, the screen keeps flickering wildly.
The problem improved after the 1.03 firmware upgrade (for a while it was flickering uncontrollably ALL the time and was virtually unusable) but it has not gone away.
Any suggestions would be very welcome, either for how to fix this issue or how to get Apple to, you know, let me TELL THEM that their adapter firmware fix has NOT solved the issue, since my phone support has expired. :/

I have a new Mini DisplayPort to Dual-Link DVI Adapter to allow my original Apple 30" Cinema Display to connect to the new Mac Pro. Shipped straight from Apple, it is firmware version 1.03. I've never had flickering issues, but the display will often go black (possibly after a screen power save) and not come back. when this happens I am still able to connect to and use the Mac via remote connection. But the only way to get the screen back is either to unplug the adapter and plug it back in to the Mac, or to shut down and power up the Mac. This may be a separate issue, so I'll also post it standalone...

Will the old 23" ACD work with the Mini DisplayPort to Dual-Link DVI Adapte

Will the old 23" ACD work with the Mini DisplayPort to Dual-Link DVI Adapter and the new MacBook Pro?
Apple Store says it is for the 30" only.
Thanks ... Ken

I'm not so sure about that. I'd say the jury's still out until someone gets one and tries to use it single-link.

Trouble Playing DVDs with Mini DisplayPort To Dual-Link DVI Adapter ?

So I went and bought the Mini DisplayPort To Dual-Link DVI Adapter for my 30" Cinema display to connect to my MacBook Pro.
I open up Apple's DVD player and 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??

You've probably fallen into the nasty pothole created by the advent of HDCP compliant graphics on Apple computers and a mishmash of older and newer Apple gear that does/does not support HDCP.
Ironically, if you were using an older Mac notebook (prior to late 2008), everything would play just fine because HDCP wouldn't come into play anywhere.
That is my guess as to what is happening.

Problem w/New MacbookPro, Cinema 30, Mini DisplayPort to Dual-Link DVI Adap

Hi, I have a new MacBook Pro with Miniport connected to a Cinema 30 using the Mini DisplayPort to Dual-Link DVI Adapter. I upgraded from the previous version of the Macbook Pro w/built-in DVI and never had a problem.
From the moment I started using this new miniport adapter with the Cinema 30, I noticed intermittent graphic anomalies. Most of the time, discolored lines will start rapidly popping in and out across the screen - especially noticeable with dark backgrounds. Here are a couple of quick videos that visualize the problem.
Video 1 - http://is.gd/krM6
Video 2 - http://is.gd/krLT
I'm also experiencing issues with the cursor randomly jumping across the screen.
It's isolated to the 30 cinema and the adapter. The Macbook Pro works fine when connected tot he new 24" LED Cinema.
Any advice on what to do? Is it a faulty adapter? Is there a SW/Firmware upgrade?
Thank you!

I'm having the exact same problem. Have you called Apple and if so, what did they say? I read in a magazine that you can switch to the NVIDIA GeForce 9600M GT graphics processor some how with in our computer. I don't know how or if this may solve the problem.

MBP + Mini DisplayPort to Dual-Link DVI Adapter + 30" = blue flickering

Hi everyone,
I was wondering if anyone has found a solution to this problem? I use an Apple 30" Cinema Display and it worked fine with my Late 2007 MBP. Now I got a new Core i7 MBP and the Mini DisplayPort to Dual-Link DVI Adapter. At first all works fine, but after a while of use I get blue (and sometimes also green) flickering pixels in areas that are supposed to be black. This does usually not matter while working, but watching movies for example is completely unbearable.
I’ve read a few threads, but most seem to have different problems like 1/3 of the screen flickering or the external display going completely off for a second. That is no issue over here. It is just that the longer I use my setup the more flickering gets added. At first I thought I don’t suffer from this, because it goes from practically flicker-free to totally weird flickering when everything is in use for more than a few minutes.
I’ve set up the Computer Name screensaver. If I run it right after turning on my MBP all is fine. Running it again after 2-3 minutes of use shows the first blue pixels flickering. It does not need 30 minutes to arrive at what seems like more flickering isn’t possible anymore...
Any recommendations or solutions are really welcome!
Things I already tried:
- different USB ports for both the adapter and the Cinema Display
- other power outlets
- powering the adapter from a USB hub or via an iPod wall charger
Thanks
Björn

I would even try out crazy adapter combinations if there were any available...
At last! I’m quoting myself, because I finally found an alternative adapter which works! I have no more flickering pixels/lines. Black looks and stays completely black as it should! I can finally use dark backgrounds again and watching movies with black borders or dark areas is no longer a pain.
The adapter was very hard to get. It currently is not sold here in Germany and I got it off eBay where there was only 1 available. I’m happy, because I got it for less than 90€ which is even a little cheaper than Apple’s flicker-creator.
The adapter I now use is the Sapphire Active DisplayPort-to-(Dual-Link-)DVI adapter. It has a USB connector for power like Apple’s adapter. The only thing that’s added is the DisplayPort-to-Mini-DisplayPort cable since it is not available with Mini-DisplayPort. Here’s a picture of it:
Hope this helps others, too!

PS: This adapter seems to be normally meant for ATI’s GPUs in order to connect 3 displays which they call Eyefinity.

Mini displayport to dual-Link DVI Adapter - flicker issue resolved

I have a late 2013 Imac 27 inch and I had a 30" Dell 3007wfp as my second monitor on the standard DVI adapter for a while at low resolution. I finally got off my behind and bought the mini displayport to dual-Link DVI Adapter... I was excited to see it in all it's glory. It immediately started flickering wildly and I thought I'd do some reading to see how I could resolve it. Pointers to making sure the adapter was version 1.03 didn't help.
http://support.apple.com/kb/ts3232
I already had it. I was getting ready to bite the bullet and just take it back when I decided to see if I had another DVI cable to swap the one I was using out "just in case". I found another one.. same length. Darn it. Then I noticed the DVI cable diameter I was using was significantly thinner than the one I found in my box of etc... What the heck? I thought.
Connected it and BOOM! Vivid colors, high resolution, no more flickers!! Issue gone. Happy days!
Thought I'd post this to possibly help the next schmoe who is in the same situation

Mini DisplayPort to Dual-Link DVI Adapter

Hi, I am using the Apple Mini DisplayPort to Dual-Link DVI adapter to connect my 30" Apple Cinema Display (Aluminum) to my MacBook Pro 13" Retina, I am passing through the Belkin Thunderbolt Dock, so I connect the Dock to the MBP via the Thunderbolt port and then I connect the Mini DisplayPort to Dual-Link DVI adapter to the Belkin Dock and then to the Apple Cinema 30".
One of the issues I am having is that with the Cinema Display I am working at 2560 x 1600 resolution, much larger than the native MBP resolution, I am also using my apps in Full Screen mode, so when I disconnect from the Cinema Display and go back to use the MBP the apps in full screen mode still are at a higher resolution than the native MBP resolution and they are off the screen. Is there a way to manage a profile with different resolution so the Mac OS will switch automatically resolutions?
Also does the Apple Mini DisplayPort to Dual-Link DVI adapter usb cable supports USB 3.0 ?
Thanks

Hey guys,
I found out an answer by myself...
The missing link : the MacBook Pro needs to be powered... as in you need to plug the charger in...
In conclusion, you simply plug everything, turn on the MacBook Pro, close the lid, and there you go !

Mini DisplayPort to Dual-Link DVI Adapter - Firmware 1.03 Release Date

Mac Mini using dual-link to ACD 30" wake from sleep problem?

I have a new mac mini and rather new 30"ACD using the display port via dual link adaptor. The screen looks find but sometimes when I put the mini to sleep and turn the display off, and then turn the display on and wake the mac mini, nothing appears on the display. I don't think it is every time, but it occurs. I have my keyboard attached to the display with the usb connection, and so I can choose from the display options to turn the mac mini off or put to sleep when turning off the display manually. I have used this sometimes but prefer not to.
When the display doesn't show any image I have to hard shut down the mac mini, then start it up and leave the display on, then the image shows up.
Is there a solution to this? I don't mind using any one surefire way to wake the whole system wake from sleep. Either turn off or turn on the option where turning off screen also brings up option to put mac mini to sleep or turn off. Don't use that option at all. Attach the keyboard only to the mac mini directly, etc.
Any solutions would be appreciated.

What is the firmware version of your Mini DisplayPort to Dual-Link DVI Adapter? I've read many reports on how this particular piece of Apple kit is just not working properly (http://www.9to5mac.com/DisplayPort-Dual-Link-DVI-Adapter, http://foliovision.com/2009/12/20/apple-dual-dvi-mini-displayport-adapter-mb571z).
I've seen some people report that running firmware version 1.02 (or now 1.03?) solves their problems. I've also heard that people have had to resort to actually exchange their adapter in an Apple Store and hunt through new boxes to find adapters with the proper firmware version.

There is a small "1" stamped in the sheet metal next to the single link DVI connector, and a small "2" next to the dual link DVI connector. The single link is closer to the motherboard.
There should be a PDF Users Guide on the Mac CD that came with the board. Page 17 shows the connectors.

What does the 'Dual' in Dual-Link DVI Adapter refer to?

We purchased a 'Mini Display Port to Dual-Link DVI Adapter thinking it meant we could split the output to two monitors such as the Matrox TripleHead2Go or Matrox DualHead2Go.
Having received it, we are unable to determine the advantage of using this product other than a normal Mini to DVI adapter. Hopefully the Dual doesn't refer to the addition of a USB port. Thanks for any replies.
--Bruce D. Meyer

DVI uses a transmission format called "transmission minimized differential signaling" (TMDS). In the DVI standard, single-link means that there's one 165MHz TMDS transmitters connected, and dual-link means that there is 2 (doubling the bandwidth of the cable). So, a single-link cable can transmit 1920x1200 at 60 Hz, whereas a dual-link can transmit 2560 x 1600 at 60 Hz (about 1.8x the resolution).
So, a dual-link cable will allow you to use higher resolutions and frequencies (though common LCD panels are locked at 60 Hz) than a single-link one.

Is the 7800GTX 512 MB dual-link?
