I just bought a Mac Pro 2010 with an ATI5770 that has 2 x Mini Display Port (DP) and 1 x DVI.
The current configuration is as follows:
- Mini DP A > passive HDMI adapter > 1920 LCD
- Mini DP B > passive HDMI adapter > 1920 LCD
- DVI > passive DVI to HDMI adapter > 1920 LCD
In this configuration, only two out of the three monitors will work at any given time. From reading up on the topic, I understand that I'll need at least one active adapter in order to get all three monitors going together.
What is the minimal number of active adapters I need? i.e. do I need one or two, and on which port(s)? If that matters.
A recommendation for suitable non-Apple adapters would also be appreciated.
