On a related note, AMD technical support is slowly responding to a support ticket I filed a couple weeks ago on the 5770 and they are now claiming that the 5770 requires an ACTIVE DisplayPort to mini DisplayPort adapter whereas the 4890 did not require this, which makes no sense to me. When I pressed for specific examples of what they meant, they sent me a list of qualified DP/mDP adapters, but a Google search could not find any of them. I've replied asking for more details. We'll see where that goes.
After several weeks and numerous back and forths with AMD support, I'm giving up on trying to get a reasonable explanation on why the 5770 does not work with the iMac. They are still claiming that due to the way EyeFinity was designed, you need a powered/active adapter to go from DisplayPort -> mini DisplayPort but they cannot provide any examples of such an adapter or provide a technical explanation of why this is even needed.
I returned my 5770 a couple weeks ago, but I was still curious to figure out the real problem here. Unfortunately it doesn't seem like AMD support is interested in helping out and I don't have the patience to keep dealing with them. It would seem that anybody with a 5770/5870 hoping to connect it to the iMac is going to be out of luck.
If anyone with a 5770/5870 has the patience, file a support ticket with AMD and see if you can get any further.

相反FX系列DP显卡则无此问题,可以支持苹果LED显示器,具体测试过的型号有
FX540
FX580
FX1700
FX1800
FX4800
另外经测试,所有4系列的显卡也没有问题,可以支持苹果LED显示器,具体测试过的型号有:
HD4670
HD4890
此款DP对MINI DISPLAYPORT转接线的销售链接如下：
