MacBook Pro Retina with graphic card switching. Profile... card dependent?
The MacBook Pro Retina has 2 graphics cards, sort of. There is the integrated Intel 4000 "card" and the NVIDIA card (1gb VRAM). By default, dynamic graphic card switching is enabled in System Preferences, Energy Saver. After installing the application "gfxCardStatus" one can see which card is being used. If you have dynamic switching active the card used is dependent on which applications have been launched. For example, if Photoshop or Bridge is launched then the card will switch from Integrated to Discrete (NVIDIA). That raises the question: Is the profile generated by calibration software valid for both cards? I would not think so. This raises the question of how this is managed. I would always want the screen to be set up for imaging apps like Photoshop. Add in the variable of an external monitor and it could get complex. Any ideas? Barry Rudick

I would not think so.
If it's all digital and identical processing is being applied (ie. the same pixel values end up in the frame buffer - and people are likely to notice if this is not the case), then why wouldn't it be valid ? (Of course there is always the possibility of bugs, ie. that a videolut not being applied to both outputs etc.) Graeme Gill.
