Morning, I recently got a 15" Mid-2015 MBPr with the AMD Radeon R9 2GB. I was hoping to run three external screens, do any of you know if this is possible? I currently have the following screens on my desk. 1x 24" Dell via Thunderbolt to HDMI to DVI Adapter. 1x 22" ASUS Thunderbolt to HDMI 1x 22" ASUS (currently on a a Mac Mini). Was hoping to go HDMI to HDMI... though when I try I can never get all three monitors working at once. Thoughts?
