• MONITORS FOR MAC PRO 2009 MAC

I have a ridiculous addendum to this after reading about all this again. Hello Ski and Blue Monkey (this is "Dick the flick" as was here - but i can't get back into my original account Peter). No more crawling under my work station to unplug/plugin the monitor. I just switch the Input Source from VGA back to DVI-D and the monitor works as expected. A message comes up saying there is No VGA Cable. I found that when the Dell is turned on that has the "noise", all I have to do is change the Input Source to VGA. On the Dell monitors there is a menu where you can select the "Input Source". I don't know what monitors you have but I have 2 Dell monitors and a Samsung. I found an easier way for me, maybe it'll work for you too. Like you, unplugging it and then plugging it in again made it work. I had the same problem with one of my monitors displaying "noise" when turning the monitors off and then back on again. It's been a while since this thread but I have something to add that may help you and/or others. Hopefully this thread will help others as well. Thanks again Ski for your help in setting this up. It's pretty cool how you can arrange the monitors in System Prefs/Displays to dictate how you can drag/mouse from one monitor to another.

MONITORS FOR MAC PRO 2009 MAC

If I understand this correctly now, I think if you have one monitor that can be connected via DVI you would connect that directly to the Dual Link output on your Mac and if you have two more monitors that can be connected via VGA you would only need two Apple Mini DisplayPort to VGA adapters. If one of your monitors is VGA then the Apple Mini DisplayPort to VGA adapter can be used for the monitor connected via VGA, one DVI monitor connects directly to the DVI Dual link output and the second DVI monitor needs the Apple Mini DisplayPort to Dual-Link DVI Adapter.Īll three of my monitors can be connected via VGA or DVI so I used DVI for my two main monitors and VGA for the new (third) monitor since I already had an Apple Mini DisplayPort to VGA adapter. If your three monitors are all DVI you need two of the Apple Mini DisplayPort to Dual-Link DVI Adapter's.

I was only able to get one Apple Mini DisplayPort to Dual-Link DVI Adapter today because Adorama only had one in stock.įrom the Apple document I got the impression that one might do the job in my case so I tested it and it works. Other than that, they've worked flawlessly.

So basically, I never turn off monitor #1. That can be fixed by unplugging the USB ports from BOTH of the DVI adapters, then plugging them back in. But if I turn off monitor 1 and then turn it back on, it displays "noise" on the screen. I found that I can turn monitors 2 and 3 on and off at any time. I have my monitors connected to a rackmount power strip with individual power switches so I can turn them on and off individually. The Mac Pro (Mid 2010) provides two auxiliary power ports. The ATI Radeon HD 5770 graphics card requires one auxiliary power connection and the ATI Radeon HD 5870 requires two. Mac Pro (Mid 2010) and Mac Pro (Mid 2012) systems come standard with the ATI Radeon HD 5770 graphics card, but may be configured with an ATI Radeon HD 5870 graphics card or two ATI Radeon HD 5770 cards.

Learn about supported graphics card and display configurations for the Mac Pro (Early 2009), Mac Pro (Mid 2010), and Mac Pro (Mid 2012) configured with either an ATI Radeon HD 5770 or Radeon HD 5870 graphics card. Mac Pro (Early 2009), Mac Pro (Mid 2010), Mac Pro (Mid 2012): Supported display configurations Is that correct?Īlso, why is there a USB input next to the DVI input where you plug-in the DVI cable on the adapter? Does this input just behave like a hub so you can daisy chain the USB connections from one display to another so you only need to use one USB input on the Mac?ītw, the Mac Pro that I use in my music studio which I want to use the 3 displays on was purchased 4/21/12 so I'm guessing that makes it a mid-2010 Mac Pro, if that makes any difference. Since the documentation doesn't mention it, may I ask what the USB connection is for? I'm guessing that it's a power source for the adaptor. Wow, not cheap adaptors but if it works it'll be worth it.

Thanks for the quick reply with info and links! So those take care of two monitors, and my third is connected directly to one of the DVI ports on my video card. If you don't have exactly those adapters, it's not going to work. Based on my system, which is a little newer than yours based on what you have listed in your profile, this is the magic documentation:
