So I have a 2014 MacBook Pro Retina and when I hook it up to an external monitor via a Mini DisplayPort to DP adapter and then go to calibrate that monitor the calibration process says that monitor can not display the full color spectrum that it needs to. I have tried an asus PA279q and a Dell U2410 and both come up as 80% srgb and 80 argb both should be much wider. I have tried a few different cables with my computer but both come up with the low color output when they shouldn't be. Is there something I need to do with the Iris card to help with this, I am really at a loss!
