Hello everyone! I have a Mac Pro 1,1 (upgraded with ssd/21gb ram/ATI HD 5770 mac version) with Yosemite 10.10 installed. I want to connect 2 monitors to my mac. Ati HD 5770 has one DVI and two Mini DisplayPort outs. I bought an adaptor (Apple Original A1307) Mini DisplayPort -> VGA. So I`ve tried this configuration: DVI out --> DVI-to-VGA adapter --> VGA Monitor 1 (BenQ 22") Mini DP --> MDP-to-VGA adapter -- VGA Monitor 2 (Samsung 17") OSX "sees" both monitors (in system preferences->display), but signal is sent only to the monitor 1 (DVI out on video card). I`ve switched the monitors between them. Same problem, the monitor from MDP out, still not receiving signal. I`m doing something wrong? Or I need to set something in OSX? P.S. Excuse my english.
