Re: HD 6870 Eyefinity Help!
Hi!, I never heard the limitation of just 1 DVI to VGA adapters.
The most common problem here is the DP to DVI. Many brands sells them as active, while they are not, at least not as active as ATI AMD wants!.
In the "old times" with my 5870, I have the same problem untill I find the right dongle (which was one from VGA builder SAPPHIRE). Dont think the adapter its ok if it works while not in eyefinity mode (grouped) because the needs of active capabilities its only at eyefinity is enabled.

Many thanks for the reply, appreciate it.
The DP to DVI adapter I have is an XFX one, with the ATI certified Logo on the box, and also on the adapter itself, is the word "Active'. The dongle itself, I have tested, and when attached to a DVI monitor, it works in eyefinity.
After much searching about, I have narrowed it down to the following problem:
The 6870 has two types of DVI (My fault for not understanding the difference). 1 is a DVI-D and 1 is DVI-I, and from what I understand, only one is capable of outputting both Digital and ANalogue signals, whereas the other one will only output Digital, so even if I use a DVI to VGA adapter on both, only 1 will output a signal to the projector.
So I am going to switch to using:
DP to VGA
DVI to DVI
DVI to VGA
And that should enable all 3 monitors to work!

Hi again,
Of course, you cannot use a DVI to VGA adapter if the DVI output its DVI-D.
The DVI its the generic standar for the conector. But there are many types of DVI as the signal can be digital, analog or both. DVI-I its the most common and send trough the conector digital and analogic signal (so you can attach the DVI to VGA adapter) but the DVI-D its only digital, so you cannot use the DVI-VGA adapter (at least not the standar cheap dongle), so your reffered configuration should work!
