I use a retina MBP 15" laptop for all post processing and computing needs. When I calibrate the retina screen, I get above 90%of the RGB spectrum. At least thats what I think it is. I just added the Dell monitor in the title and calibrated. The first calibration yielded like 90% RGB, but it was too bright. I adjusted the brightness, as well as the ambient light and re-calibrated. The profile it generated is only 85% RGB. Now, I have done minimal research into this, but is that a decent %? I feel like something is off but I really dont know where to start.
