Jun 24, 2016 12:07 PM in response to DanSudkampby lllaass,It has nothing to do with the SSD at all.
You said "2009 Mac Pro (which has one DVI input and two mini Displayport inputs)."
Do you really mean the graphics card in the 2009 has two mini displayport outputs and one DVI output?
What specific graphics card is it?
Does any of the two mini displayport outputs work as only connection?

Jun 24, 2016 12:50 PM in response to lllaassby DanSudkamp,★HelpfulHi, thanks for the reply. I guess that is what I meant, the graphics card has those ports. ATI Radon HD 5770 1024 MB.
I'm surprised to hear that it would have nothing to do with the transplanted SSD, as the mini Displayports worked just minutes earlier with the old drive that was previously installed. But I'll take your word for it!
And yes, I did try using mini Displayport as the only connection, it didn't work that way either. Also tried resetting the SMC and NVRAM, and neither of them resolved the problem, but thanks anyway for trying to help!

Jun 24, 2016 12:28 PM in response to DanSudkampby lllaass,Does the DVI output work?
Does the mini displayport cable and monitor input now work on another computer?
With two display connected does the problem one show in About this Mac>Displays or About this Mac>System Report>Graphics/Displays?

Jun 24, 2016 12:50 PM in response to lllaassby DanSudkamp,The DVI output is working fine. And yes the mini Displayport and monitor work with another computer. I also just successfully used a VGA-to-mini Display with the computer in question and it worked fine, meaning the ports are fine. So the problem I guess is with the adapter/cable I'm using. Weird that it would be fine with other computers and not this one... Anyway, thanks for the help.

Jun 24, 2016 2:12 PM in response to DanSudkampby Grant Bennet-Alder,You can only run two out of three "legacy" displays (DVI or other displays with adapters) off that card. To get the third, you need to be using an ACTIVE adapter or a direct DisplayPort or Mini DisplayPort connection, no adapters.
That is why the query about whether just using one adapter on one Mini DisplayPort works by itself.
Even if it won't light up the display, if you have any ONE display working you can look in About this Mac to see if the display_name for any of the others is showing.

Jun 24, 2016 2:19 PM in response to DanSudkampby Grant Bennet-Alder,The question you did not ask directly, is, "Does Mac OS, as installed, always contain "Drivers for every appropriate Mac?".
The answer is Yes for Purchased versions, and NO for factory installed or re-installs of the original factory-shipped versions. Factory Installed contain only Drivers for the specific model they shipped with.
So if that drive has a MacOS that was factory-installed for a different model Mac, it is possible it does not contain all Drivers you need.
