I posted this in the Macbook Pro forum but I thought it may be better answered here since it is directly related to my photography entry. So I have a 2014 Retina MBP 15" and I hooked it up to my Asus PA279Q via a Mini DisplayPort to DisplayPort cable. When I hook it up it looks very yellowish and when I calibrate it with my Spyder Pro 4 it says the display can only display 60% SRGB and the same for Adobe RGB. Hooked up to my pc it is 100% SRGB and 99% Adobe RGB so I am doing something wrong. I have tried two cables and got the same result and try different ports. The colors in the Asus look horrible! I tried switching to HDMI but Adobe RGB is disabled in HDMI. So my question is am I doing something wrong, do I need a different cable or am I missing a setting? Any help would be good I thought they fixed the wide gamut issue awhile ago. I am running El Capitan. I did try the fix here http://www.ireckon.net/2013/03/forc...ix-the-picture-quality-of-an-external-monitor And saw that it renamed my monitor to EDID RGB Override but it did not make any difference to color and calibration. My sensor says it is anywhere from 60%-80% sRGB or aRGB when it is hooked up via displayport to HDMI when the monitor is in both sRGB and aRGB mode.
