>From what I learned there are two display devices normal (sRGB) and wide gamut. My monitor is a wide gamut device. If you load the (Dell) profile for the device Windows is wide gamut enabled. The same goes for loading the AdobeRGB profile. Once I load a wide gamut profile the Chrome browser is displaying two versions of a sRGB jpg. Apparently you need a colorimeter to calibrate sRGB and a spectrophotometer to calibrate wide gamut. I don't understand the difference (yet).
I set everything to sRGB and disabled wide gamut. Now I see two identical renderings in Chrome and identical renderings across LR, all other browser and ipad/iphone.
