“OS X 10.10.3 has added 60Hz support for the Dell UltraSharp 27 Ultra HD 5K Monitor at 5120×2880 when dual mDP-to-DP cables are connected to dual Thunderbolt 2.0 ports on the 2014 iMac 5K and 2013 Mac Pro ‘tube,'” rob-ART morgan reports for Bare Feats. “So here’s another OpenGL ‘shootout’ that includes the 2010 Mac Pro tower sporting top NVIDIA GPUs with two or more DisplayPort 1.2 ports.”
“The Dell UltraSharp 27 Ultra HD 5K Monitor is now the ‘constant companion’ of our 2013 Mac Pro ‘turbo tube,'” morgan reports. “The iMac with 5K Retina display sitting next to it can no longer taunt it. The two Macs have equally amazing displays. Though we tested at the full 5120×2880, most of the time both displays are set to the scaled 2560×1440 with HiDPI ‘Retina’ mode in effect.”
“The Mac Pro tower continues to benefit from the efforts by NVIDIA engineering to provide downloadable drivers with each revision of OS 10.10.xx” morgan reports. “The ‘Maxwell’ class of GPU is able to run the Dell 5K display’s full potential.”
