"about my mac" shows Intel 3000, does not mention AMD 6490. According to support article https://support.apple.com/en-us/HT202053 it should show both. Can anyone confirm? And yes, I have had some recent issues with my display. The AMD 6490 does show up in a system report but I wonder if it has been disabled since it doe snot show up in "About my Mac".
MacBook Pro (15-inch Early 2011), OS X Yosemite (10.10.3)
